Question 1

How do the difficulty levels for Sudoku and Wordoku work?

Accepted Answer

Grading and Difficulty Levels

There are several different Sudoku puzzle variations available in Puzzle Maker Pro:

Our Wordoku puzzles are graded with the same rules:

One of the important things when solving, publishing and creating sudoku puzzles, is to set the difficulty level. In other words: Grading the puzzle.

When you look at sudoku puzzles from different sources, such as magazines or puzzle books from mainstream or independent publishers, websites, or apps, you'll find that a 3 star or medium sudoku puzzle does not always have the same characteristics.

You may notice that sometimes you can easily solve a 6 star (very tough) sudoku puzzle, while you might get stuck at a 3 or 4 star puzzle in another puzzle book, or even in the same puzzle book.

2022 Changes

In earlier versions of Puzzle Maker Pro, we've used various websites to 'calibrate' our sudoku algorithms. At the start of 2022 we've released an update of Puzzle Maker Pro that has a brand new sudoku generation engine.

To help you, as a puzzle (book) publisher, we disclose the rules by which our sudoku puzzles are graded. We've determined these rules by examining puzzles from various sources, and we've tried to set up a balanced grading approach, that can also be logically explained.

Sudoku 9x9 Grading

First of all: Sudoku is a logic puzzle, not a math puzzle. Sudoku grading is based on the logical operations that are required to solve the puzzle.

Note: Some vendors use the number of clues (a.k.a. the number of digits in the puzzle when you start solving it) to grade the puzzle. Please be aware that this is very wrong: There are sudoku puzzles with only 17 clues that would be graded as Easy by all sophisticated grading systems.

Logical Operations

Although this article is not a Sudoku tutorial, if you want to understand difficulty levels, you'll need to understand the types of logical operations that can be used:

Naked Single: Only one number is possible in a given cell (square), all other numbers have been eliminated
Hidden Single: Even though there are several numbers in a given cell, that cell is the only location (in a row, column or box) where the number can be placed
Naked Pair, Naked Triple, Naked Quad: 2, 3, or 4 numbers that are the only possibilities for 2, 3 or 4 cells
Hidden Pair, Hidden Triple, Hidden Quad: Just like the Hidden Single, there are other numbers in the 2, 3 or 4 cells, but the 2, 3 or 4 numbers that form the Pair, Triple or Quad, can only be placed in these cells and not elsewhere.

In general, for Sudokus up to 5 star level (which is called very hard, in Puzzle Maker Pro), you can find Naked Singles, Hidden Singles, Naked Pairs, Naked Triples and Hidden Pairs.

Other operations can found on several websites and in sudoku books, such as X-Wing, Y-Wing, (Simple) Coloring, Tracing, Overlay Reduction (also called Pointing Pair / Line Box Reduction), etc etc. These operations can be needed for 6 * and up.

Difficulty Levels

Level 1: Only a 'few' Naked Singles and Removing Options (if a '7' is already present in a row, column or box, you can remove it from each cell in that row, column or box)
Level 2: Many Naked Singles
Level 3: Level 2 plus a few Hidden Singles
Level 4: Level 3 plus many Hidden Singles and possibly a Naked Pair or Naked Triple
Level 5: Level 4 plus more Hidden Singles and several Naked Pairs or Naked Triples
Level 6: Level 5 plus more Naked Pairs / Triples and possibly a 'Very Hard' technique (e.g. Hidden Triple or Overlay Reduction)
Level 7: Level 6 plus more 'Very Hard' techiques and possibly a 'Tough' technique (e.g. X-Wing, Coloring)

Is this a big change compared to the old sudoku puzzles?

No, but as part of the new (2022) sudoku 'engine', I decided to make the grading rules more explicit and to offer transparency about them.

Grading of other Sudoku Variations

For regular 9x9 Sudoku puzzles, there are quite a few websites and apps that can be used to solve and/or grade the puzzles. For other formats, ranging from 4x4 to 25x25 sudokus, and for the variations such as Twins, Triathlon, Marathon, Samurai and 3D sudoku, there is no such thing. (And, as far as I know, nobody else is transparent about their grading system. If there's any standard to be found anywhere, I'll be happy to use that for Puzzle Maker Pro)

The approach that's used in Puzzle Maker Pro is easy to use, but there are some caveats, which I'll explain after describing the main approach.

Main Approach

A 9x9 sudoku has 81 squares, while a 10x10 sudoku has 100 squares and a 16x16 sudoku has 256 squares. Sudoku variations have more squares as well. For example, a Triathlon sudoku has 189 squares and a Samurai sudoku has 360 squares.

The approach chosen for Puzzle Maker Pro is to scale the difficulty level thresholds proportionally: When a 9x9 sudoku needs 7 hidden singles to be considered Level 3, a 10x10 sudoku would need 9 or 10, a 16x16 sudoku would need 22 and a Samurai Sudoku would need 32 hidden singles to be Level 3.

Small Sudokus 4x4 and 6x6

For the smaller sudokus, there are fewer difficulty levels, since certain options (quads) cannot occur, and even in Hard 6x6 sudokus, triples will be very rare.

Caveat

However, the occurence these patterns, such as naked or hidden triples or quads, does not increase proportionally, at least not linearly, but faster than that.

For example, when you have a 9x9 sudoku, where in a given row, 5 clues are given. In that case there are 4 squares empty, which 4 possible numbers for these squares. The chances that there is a (naked or hidden) triple or quad are very small. But if you compare this to a 25x25 sudoku, where 5/9 or around 60% of the clues are given, the result is very different. You'd have 15 clues and 10 empty squares. The odds of having triples or quads are still small, but a lot bigger than for a 9x9 sudoku.

Currently, Puzzle Maker Pro does not compensate for this additional complexity.

Like the older version, the difficulty levels 3 and 4 will be reasonably easy to solve, level 5 will be comparable to regular 9x9 level 5 difficulty, but levels 6 and 7 can be relatively much harder to solve. Of course this all depends on the actual puzzle format and variation.

Question 2

Height Map Editor Tutorial - Quick Overview

Accepted Answer

The Height Map Editor is an interactive tool to create your own 3D landscape. You can raise and lower individual squares (blocks) and level entire rows and columns.

There is one basic rule for the height of the cells: cells in front have to be lower than cells in the back. (Otherwise there would be a path on the back of the cell, which is not visible).

The Height Map Editor always applies this rule automatically, which may cause some unexpected results when you’re changing the height of some cells. That’s why there’s an Undo option, so you can always go back to the previous version of the height map.

In the screenshot you can see:

You can save the height map as a preset for later use.

Question 3

How to create Criss Cross puzzles with Puzzle Maker Pro - Criss Cross

Accepted Answer

This tutorial shows how to create Criss Cross puzzles with Puzzle Maker Pro - Criss Cross.

The main tutorial for Crossword Variations shows all the steps and information that applies to all the different puzzle types.

Introduction

Criss Cross is a type of crossword puzzle where words are loosely connected to each other, like the example below.

https://malcolm-en-gb.s3.eu-west-1.amazonaws.com/instances/wuGqS3zSeN/resources/piIUZvmTdp/Criss%20Cross%20-%2000%20Overview.png (Criss Cross - 00 Overview)

In this tutorial we'll show you how to create this type of puzzle using your own word list.

Puzzle Maker Pro - Criss Cross

All the options and functionalities for Criss Cross are covered in the main tutorial for Crossword Variations.

There are a few details to pay attention to:

Style 2 tab

As you can see in this screenshot, using full size word numbers influences the puzzle generation, because each word number needs a separate square. In essence this means that there are fewer squares for the words. In general this is not a problem, but it's good to be aware of the changes in the puzzle.

Grid tab

Criss Cross - Grid Settings

https://malcolm-en-gb.s3.eu-west-1.amazonaws.com/instances/wuGqS3zSeN/resources/Hu5J07URBL/Criss%20Cross%20-%20Grid%20Settings.png (Criss Cross - Grid Settings)

You can adjust the grid size to create puzzles that fit in the available space. For example with these image settings, there's a rectangular area available for the puzzle, and it makes sense to set a grid size of e.g. 10x25 for a natural look.

Image tab

For Criss Cross puzzles you can use the Set Title, Set Description or a Custom text for the image title and description.

Letters in a word are switched, but all the letters will be used. For example: Sudoku may result in UUOKDS,
Each word in a phrase is scrambled separately, the letters of the different words are not mixed,
Spaces, punctuation marks and other special characters are not scrambled,
Currently the module works with the standard English alphabet (A to Z).

Word Scramble Overview

To use Word Scramble, select the puzzle type in the drop down menu, or in the regular menu.

Word Scramble Overview

https://malcolm-en-gb.s3.eu-west-1.amazonaws.com/instances/wuGqS3zSeN/resources/k7jaTSc3Th/Word%20Scramble%20Overview.png (Word Scramble Overview)

When you select this puzzle type for the first time, a default list of words is shown, and the preview shows an image using the first word.

In addition to the 'basic' word scramble functionality this module has quite a few options:

Generating Word Scrambles

The total number of Word Scrambles can be set ("Quantity"), or you can use the entire word list ("Entire List").

When generating Word Scrambles, and when generating a new preview (click Next Preview), a meme style image is shown as a preview. You can configure and style these images using the Images/Meme tab.

Hoewever, for Instant Puzzle Books, the images are not used, but instead the text output is used. That means you do not need to create the image output for your Instant Puzzle Books.

The text output consists of a TXT file and a CSV file, see also "Text Output for Word Puzzles". The CSV file can (for example) be used in Canva Pro to quickly generate images (in addition to the built-in Images/Memes option).

A default layout for Instant Puzzle Books will be used (just click "Create" to see this). With the Time Saver add-on, you can adjust the layout, using columns and customize other layout options.

Styling

Styling the puzzles and puzzle books for Word Scramble can be configured in several places:

Font Styling

You can customize the font by clicking the white panel (or the looking glass icon) in the Font Settings area. You can set both the font and the font color.

For the Instant Puzzle Books you can set the exact font size.

https://malcolm-en-gb.s3.eu-west-1.amazonaws.com/instances/wuGqS3zSeN/resources/umTwRURKAG/Fixed%20Font%20Size.png (Fixed Font Size)

For Images/Memes the font size is determined automatically, since this will vary depending on the image size (the number of pixels).

Introduction to Letterbox Puzzles

A Letterbox puzzle consists of a grid filled with different letters. By removing all letters that occur twice or more, the resulting letters will form a word - read from top left to bottom right. The puzzle in the screenshot below is an example:

Letterbox Tutorial Overview

Select "Letterbox" in the Puzzle Type dropdown menu or in the Word Puzzles menu
Set the number of rows and columns for the grid (see the preview [5]), and the quantity of puzzles you want to generate
Your word list. By default, a short word list is added, but you should always use your own word list (see also the next paragraph)
"Verify" your word list - check that all the words have unique letters
Preview panel for the puzzle or the solution

Using Your Word Lists

Puzzle Maker Pro - Letterbox works with word lists or text files that have a single word or short phrase on each line. If there's also a clue or description after the word (as in: "word:clue"), the clue will not be used.

Each word must consist of unique letters only, since the aim of the puzzle is to cross off all duplicate letters. (Actually, "duplicate" is a valid word).

After you type or copy your word list, or after selecting a word list file, you can click the "Verify" button to verify all the words in the word list. It will give a warning for words that have duplicate letters.

When generating puzzles, words with duplicate letters will be skipped.

Letter Options

Letter Options Overview

On the "Letters" tab you can find several options to control the letters that are used in your puzzle:

Even though your word list may contain spaces and other characters, like hyphens or commas, you can easily remove these from the words
"Fill Characters": After the word is placed in the grid in random positions, the other squares are filled with 'noise', random characters from the set of "Fill Characters" that you provide. By default it's set to the regular English alphabet. Letters that also occur in the hidden word, will not be used as noise.

You can get creative with the Fill Characters, e.g. use only certain letters, or use digits as noise in the puzzle, like the example below:

Letterbox Multiple Fonts Grayscale

You can choose to add Bold and Italics letters to the puzzle. Random letters will be Bold or Italic, if the selected font supports this.
Add more color variations: Use up to five colors or gray shades in your puzzle (see next paragraph)
Click "Next Preview" to generate a preview with the changed settings. The preview will be shown in the preview panel at the right.

Using Multiple Colors

Letterbox Multiple Fonts Colors

You can also use multiple colors or multiple gray shades for the letters. In total you can use five different colors:

You can select a color in the font properties window. When you use three different fonts, you can select a different color for each font. These colors will be randomly assigned to each letter. (That means: If you select a red color for "Arial" and a green color for "Times New Roman", you can get four different combinations: Arial/Red, Arial/Green, Times New Roman/Red and Times New Roman/Green)
You can also add two more colors by selecting the "Color Variations" option. You can then use the two color panels to select additional colors
You can mix and match: You can select up to three different fonts and use the same color for each, you can also select "Arial" three times, but select a different color for each font.

Styling

The "Styling" tab offers several options to change the look and feel of your Letterbox puzzle, in addition to the differernt font options.

Letterbox Styling Colors

Letterbox Styling Colors

You can set the Canvas color and the Cell Background color. The "Cell" is the square in which each letter is placed. The Canvas color is only shown when padding is used [3]
You can set the width (weight) of the Cell Border and the Color. In the screenshot we have selected a red line of 20 pixels. (This may look different depending on the image size that you selected on the Output Settings tab)
Padding - You can choose to have each letter in its own square, with a little padding around it. The empty space will have the Canvas color:

After selecting “Mazes 3D Isometric” in the drop-down menu at the top, you’ll see a view like this:

Every Puzzle Maker Pro module consists of several parts:

The puzzle settings at the left, a puzzle preview (6) at the right, buttons to create puzzles or previews at the bottom (5) and the option to display the puzzle preview or the solution preview (7).

For Mazes 3D Isometric you’ll see the following options:

The best thing you can do, is to change colors, move sliders, and change other options, click Preview, and see what happens.

Maze Generator

The Maze Generator can be configured by you in several ways: by changing the maze generator algorithm, and by controlling the start and end points.

Maze Generator Algorithm

The maze generator is a mix of several algorithms. You can control the mix, using the “Solution Complexity” slider. Setting it to 0 (zero) will result in fairly long straight paths, while a setting of 100 will create a chaotic meandering maze. To get an idea of the results, here are two mazes with the extreme settings:

Mazes 3D Iso Complexity 0 Example

Mazes 3D Iso Complexity 100 Example

Besides the difference in solution complexity, for 3D Isometric mazes, the effect on the 3D look and feel is also different.

Start and End Point Options

There are several options to set the Start and End points:

Default: This will create a maze from Top to Bottom. The exact end-points will depend on the maze type and settings
Random: Create a path from one (randomly selected border) to the one across it
Longest Path: This will generate a maze first, and then find the longest possible path in the maze, and set the Start and End points accordingly
Manual: You can select the Start and End points, by right-clicking on the maze, and then select Start or End point from the popup menu. Please be aware that the maze, the paths in maze, the cell connections, will change every time a maze is generated.

Grid Types

The current version of Mazes 3D Isometric has several built-in 3D maps, along with a Random Map and the Custom Height Maps (requires the Height Map Editor Add-On).

The Flat map is a simple, flat map in isometric style. You can set the size using the “Rows” setting.

The Fill Colors are the main surface colors. You can set:

Canvas (1): The background for your maze. With the 3D Isometric view, there will always be the four corners of the image that are not part of the maze. You can choose a color or set it to transparent
Cell / Plane colors: there are three colors, for the top plane (2), the right front plane(3) and the left front plane (4)
For the two ‘vertical’ planes, you can choose to set a fixed color, or to set the color relative to the Top Plane Color. The percentage you enter is calculated in the RGB color space for 24 bit color: Each color (Red, Green and Blue) has a value of 0 to 255. The percentage is take from the maximum value of 255. That means 10% is 25.5. If the top plane has an R (Red) value of 17, a relative value of 10% will set the plane R value to 42.5.

Line Style

There are three different lines to style, as you can see in the screenshot:

Outer Border: a border when there’s no maze cell at the other side
Cell Border: These are in fact the maze lines, indicating which cells are connected, and which paths can be followed
Plane Edge: The line between the top and vertical planes and between the two vertical planes. Usually this distinction is clear by the cell shading, but it’s here when you need it.

Solution Path Style

https://malcolm-en-gb.s3.eu-west-1.amazonaws.com/instances/wuGqS3zSeN/resources/qcIr48XXDR/Mazes%203D%20Isometric%20Style%20Solution%20Line%20Screenshot.jpg (Mazes 3D Isometric Style Solution Line Screenshot)

For the Solution Path you can set the width and color, and choose whether the line should be curved and/or dotted.

You can choose to use either Text or Images for the Start and End point. By default the text option is used, with the letters S and E for Start and End. You can also use control codes (Alt + number) instead of regular letters.

To use Images, you can either click on the white panels to select an image, or drag and drop an image on it.

How to use Puzzle Maker Pro - Letter Dice

Accepted Answer

Puzzle Maker Pro - Letter Dice Overview

This tutorial applies to Letter Dice

There is one add-on available for Letter Dice: Time Saver for Letter Dice

Letter Dice Explained

Letter Dice is a word puzzle, based on an existing tabletop game where a number of dice is being thrown, and you have to find as many words as possible by combining the letters on adjacent die faces. Usually 16 dice are thrown, which are then sorted in 4 rows of 4 dice.

https://malcolm-en-gb.s3.eu-west-1.amazonaws.com/instances/wuGqS3zSeN/resources/ebpePeS2Lk/English%204x4.png (Letter Dice - English 4x4)

Example of a Letter Dice puzzle for English words

The Letter Dice module can create these dice throws, and has some additional options:

Dice setups for several languages are provided, including French, Spanish, and German
Variations for 25 or 36 dice for English puzzles are included
You can create your own dice, just by typing the letters for each die on a single row
You can create additional fun innovative games, for example number games - place numbers on the dice, and the goal could be to add/subtract/multiple/divide numbers and get to 24 as many times as possible
You can create die faces with words on them, and create a game to find fun sentences or sentences with as many words as possible

Letter Dice Overview

To use Letter Dice, select the puzzle type in the drop down menu, or in the regular menu.

https://malcolm-en-gb.s3.eu-west-1.amazonaws.com/instances/wuGqS3zSeN/resources/Jyo7cLcqHE/Letter%20Dice%20Overview%20with%20Arrows.png (Letter Dice Overview with Arrows)

To create puzzles, you'll need to add the dice setup (as shown in the screenshot), and click Next Preview to generate a puzzle. Each click will result in a different puzzle.

There are no solutions (images or otherwise) for Letter Dice puzzles.

Dice Setup

By default an English set for 4x4 dice will be used. This is a set of dice - regular dice with 6 faces each - that was used for a popular letter dice game the past 30 years.

You can also select several other sets, like 5x5 or 6x6, and some other languages. Please be aware that the 6x6 English set contains some blank die faces, to increase the difficulty of the puzzle. This is not a printing error.

The letters on the die faces have been taken from public sources, however it's very easy to edit the sets yourself.

Set up your own dice

With Puzzle Maker Pro - Letter Dice you can completely customize your own letter dice game:

https://malcolm-en-gb.s3.eu-west-1.amazonaws.com/instances/wuGqS3zSeN/resources/ASJIFRpSYi/Letter%20Dice%20Overview%20Numbered.png (Letter Dice Overview Numbered)

Define the number of dice, printed in rows and columns. When a new puzzle is generated, the dice will be placed in random order, and for each die a random face is selected
Set up the Separator. If you have die faces that contain more than one letter, you need a separator between the letters. By default, the comma is used. You can use a dash or a dot or any other character that is best for you
Set up the Dice. Each die will be created from the letters on a single line. For example the top line in the example "A,A,E,E,G,N" defines a die with six faces. Without the separator you could just type "AAEEGN", but then you wouldn't be able to add "Qu" to a die face.
After editing the dice, click "Verify" to check if you have the right number of dice, and if each die has the same number of faces. (Since this is a computer generated puzzle, each die can have more or less than 6 faces). You don't have to have the same number of faces on each die, but the software will warn you, just to prevent mistakes. Missing dice will result in blanks in the puzzle
Create a new preview from your own dice

Tips and puzzle ideas

Don't forget to add / print puzzle rules in your puzzle book or printable, if you create your own puzzle types.

Word Dice - Create dice with full words on each face, optionally creating separate dice with nouns, verbs and adjectives. Goals could be to create the longest possible (valid) sentence, or to create many sentences
Syllable Dice
Math Dice - Create dice with numbers, e,g, 1 to 10, and operators (+, -). The goal could be to calculate a given number in as many ways as possible.

Font Styling

You can customize the font by clicking the white panel (or the looking glass icon) in the Font Settings area. You can set both the font and the font color.

Please be aware that the lettercase is by default set to 'Unchanged', to make sure that "Qu" is printed correctly. If you change it to uppercase (the default setting for e.g. Word Search), it would be printed as "QU".

For some other languages, such as Czech and Finnish, you may need to set it to Uppercase, to make the letters print correctly.

Grid Styling

You can customize canvas and die face color, as well as the line color and width:

First, you have to save your own presets. You can do this on the Puzzle Settings tab.

In the Time Saver, select the presets you want to use from the list on the left. (Click "Refresh List" if your presets are not showing).

Set the quantity for each presets. In the example, we set it to create 10 puzzles with the first preset, and 20 puzzles with the second preset.

Make sure the box "Use Time Saver to generate Puzzles is checked, then click the Create / Create (TS) button at the bottom left.

Flexible Grid Layouts

There are several ways to create Letter Dice puzzle books: Some books only have one puzzle per page, and include additional information, such as puzzle rules, score information and lines to write the found words. Other puzzle books have 4 or 6 puzzles on each page, and expect the puzzler to have a notebook available to write the solutions. (Hint: You can publish Letter Dice solution books / journals along with the puzzle books).

Adding Lines for the Words / Solutions

By clicking on the little gray squares in the Puzzle Layout (Instant Puzzle Books -> Page Layout -> General Layouts -> Puzzle Layout) you can also switch off some of the puzzle locations. In the example, only 3 puzzles will be printed per page. (This is a new feature in Puzzle Maker Pro v2022.14).

Puzzle Maker Pro does not print the solution lines for you. However, by switching off some of the puzzle locations, you can easily add lines or other information in Powerpoint or PDF. In Powerpoint you can use the Master Slides to set up the lines and other information just ones, and have it applied to all of the pages automatically.

Question 8

How to create Full Page Word Search puzzles with Puzzle Maker Pro

Accepted Answer

This tutorial will show how to create Full Page Word Search puzzles with Puzzle Maker Pro.

The Tutorial applies to:

Puzzle Maker Pro - Standard Word Search, with the Time Saver for Word Search
Puzzle Maker Pro - Zig Zag Word Search, with the Time Saver for Word Search

Note: You can create full page word search puzzles with either Word Search module, but if you want to create entire puzzle books with the full page layout, you'll need the Time Saver Add-On.

Introduction

Full page word search puzzles are printed on a spread consisting of 2 pages. The puzzle itself is printed on one page, the word list is printed on the second page. In Puzzle Maker Pro it's easy to generate the puzzles, but it takes a little bit of math to get it right. An example of the pages in Powerpoint could look like this:

https://malcolm-en-gb.s3.eu-west-1.amazonaws.com/instances/wuGqS3zSeN/resources/ZctWy8np1D/Full%20Page%20Example.png (Full Page Example)

First we'll explain a bit of background, next we'll show you how to do it in Puzzle Maker Pro in several steps.

Page and Puzzle Dimensions

The entire layout depends on your page setup, the trim size and margins. The puzzle dimensions should be adjusted to this. Or the other way around, if you want a certain size for the puzzle, say 30x40 or 34x44, you may want to adjust the page settings accordingly.

As you can see on the previous image, the puzzle page consists of several parts:

The title
The puzzle itself
The margins

Optionally you may want to add a page number as well.

Trim Size and Margins

There are several trim sizes that are commonly used for KDP books. For printables, you may use slightly different dimensions, corresponding to common paper sizes (Letter Size in the USA, A4 in Europe).

Let's say you want to use margins of 0.5" on each side. (This is not a requirement for Puzzle Maker Pro). This will have an impact on the printable area for each trim size:

A trim size of 6x9" will have a printable area of 5x8"
A trim size of 8x10" will have a printable area of 7x9"
A trim size of 8.5x11" will have a printable area of 7.5x10"

The horizontal:vertical ratio is important, because it determines how many letters you can use horizontally and vertically. It gets slightly more complex if we add a title, but luckily you only need to do the math once.

Adding room for the title.

In Puzzle Maker Pro, the space for the title is allocated as a percentage of the total height for each puzzle. In this tutorial we have just one puzzle per page. Let's say we set the title percentage to 5%, that means:

A trim size of 6x9", printable area 5x8", title area is 5% * 8" = 0.4". The puzzle area will be 5x7.6"
A trim size of 8x10", printable area 7x9", title area is 5% * 9" = 0.45". The puzzle area will be 7x8.55"
A trim size of 8.5x11", printable area 7.5x10", title area is 5% * 10" = 0.5". The puzzle area will be 7.5x9.5"

As you can see, the sizes are different, and more importantly, the ratio between horizontal and vertical is different. This means that the number of letters horizontally and vertically will be different:

5x7.6" has a horizontal:vertical ratio of 1:1.52, which means 1.52 letters vertically for each letter horizontally
7x8.55" has a horizontal:vertical ratio of 1:22, which means 1.22 letters vertically for each letter horizontally
7.5x9.5" has a horizontal:vertical ratio of 1:27, which means 1.27 letters vertically for each letter horizontally

For the larger trim size 8x10", the 1:1.22 ratio means a hor/vert ratio of 30x37 or 33x40 letters.

If you change the margins, you'll get slightly different calculations.

Using a fixed grid size

On the other hand, if you want to use a fixed grid size, say 30x40 or 34x44, you can also do that. Puzzle Maker Pro will resize the puzzle (image) to fit into the space that's reserved for the puzzle. This may result in a tiny bit of additional white space next to the puzzle.

Page Setup in Puzzle Maker Pro

You'll need to set up the Trim Size, the Page Layout, and the Titles.

Trim Size and Margins

https://malcolm-en-gb.s3.eu-west-1.amazonaws.com/instances/wuGqS3zSeN/resources/IHUyJmo9Gy/full%20page%20word%20search%20trim%20size.png (full page word search trim size)

You can set the Trim size on the Instant Puzzle Books -> Page Format tab.

Set the Trim Size, and optionally select Bleed. (Bleed will affect the printable area, Puzzle Maker Pro will take this into account)
Set the Margins. Optionally you can use different margins for left and right pages. In that case:
Click "Mirror Margins", and you'll also want to make sure "First is Right Page" is not enabled. This will ensure that each full page word search puzzle and its word are printed on facing pages. You'll have to add a first page later on, since KDP requires that the first page is always a 'right' page.

Page Layout

https://malcolm-en-gb.s3.eu-west-1.amazonaws.com/instances/wuGqS3zSeN/resources/5d1Y0Gf0ce/full%20page%20word%20search%20Page%20Layout.png (full page word search Page Layout (1).png)

You can set the Full Page layout on the Instant Puzzle Books -> Page Layout -> Word Search Layouts tab. (This is only available with the Time Saver Add-On for Word Search).

First, make sure to click Collate Setting "B". This will print all the puzzles first, and the solutions at the end of the book. (The solution layout can be set on the tab "General Layouts").
Layout types 7 and 8 are used for full page word search puzzles
You can set the number of word columns to 3 or 4.

Titles Setup

https://malcolm-en-gb.s3.eu-west-1.amazonaws.com/instances/wuGqS3zSeN/resources/43xHIOxl1Y/full%20page%20word%20search%20titles%20setup.png (full page word search titles setup)

You can set the titles setup on the Instant Puzzle Books -> Titles Setup tab in the Title Layout Settings area.

Set the "Puzzle Title Height" to the number you used in your calculations. 5-10% is enough to have a clearly printed title. The font size for the title will automatically be adjusted for the space you set.
The solution title height is usually not important, but you can set this as well.
If you want, you can change the font for the titles. This font does not apply to the word list.

Puzzle Setup in Puzzle Maker Pro

The previous steps were more or less the boring part. Important, but you still have nothing to show for it.

The options for Word Search are explained in other tutorials. For full page word search puzzles, you'll need to set the grid size, and have a large enough word list.

https://malcolm-en-gb.s3.eu-west-1.amazonaws.com/instances/wuGqS3zSeN/resources/g17ILUuRSc/full%20page%20word%20search%20preview.png (full page word search preview)

In this example we've set the grid size to 40 rows and 32 columns.

As with all modules in Puzzle Maker Pro, you can use the mouse scroll wheel on the Preview panel to zoom in (or out) and see more details of the puzzle.

Don't forget to set the right settings on the Advanced tab, such as spaces.

Creating the Puzzle Book - Time Saver

There are several techniques to create the entire puzzle book: Obviously there is the Time Saver, and some people prefer to create the puzzles manually, one by one, and then assemble them into a puzzle book using a separate module of Puzzle Maker Pro.

When you use the Time Saver, you have some additional options for the puzzle titles, and the whole process is faster. However, you'll have less control over the individual puzzles.

Make sure to click the "Use Time Saver to generate Puzzles" to make sure the Time Saver is used. When this is enabled, the "Create" button will change into "Create (TS)".

Time Saver - Main

https://malcolm-en-gb.s3.eu-west-1.amazonaws.com/instances/wuGqS3zSeN/resources/ZEoat0GPdZ/full%20page%20word%20search%20ts%201%20main.png (full page word search ts 1 main)

On the "Main" tab you can set some preferences:

Merge All Word Lists - this will merge all your separate word list into one huge set of words. Use this if you have many themed word lists and want to mix them all up for the word search puzzles
Separate Puzzles Per Word List - this will create puzzles for each word list. This will also allow you to use the titles of the word list files as puzzle titles.

Time Saver - Word List

https://malcolm-en-gb.s3.eu-west-1.amazonaws.com/instances/wuGqS3zSeN/resources/paLkfJB3Sr/full%20page%20word%20search%20ts%202%20word%20lists.png (full page word search ts 2 word lists)

Select all your word files on the "Word Lists" tab. Each word list file should contain just the words, one on each line. No headings, no additional information. Just the words in plain text. Just be careful when you copy word lists from the internet, you may by accident copy additional characters that cannot be processed by Puzzle Maker Pro.

Time Saver - Puzzle Setup

https://malcolm-en-gb.s3.eu-west-1.amazonaws.com/instances/wuGqS3zSeN/resources/IiDRaEaPMF/full%20page%20word%20search%20ts%203%20puzzle%20formats.png (full page word search ts 3 puzzle formats)

Finally the Puzzle Setup. Use the dimensions you calculated at the start of this tutorial (or the ones you just want to use). Optionally select the other options in each row. Just click on the cell (e.g. where it says 40 or 32 or 20 in the screenshot) to edit the number or switch an option on or off.

When you click "Create (TS)", Puzzle Maker Pro will generate puzzles and a puzzle book. (Don't forget to select Powerpoint and/or PDF on the Instant Puzzle Books -> Output Type tab).

The way Puzzle Maker Pro handles these settings:

For each word list, it will process the table with puzzle formats, and generate the quantity of puzzles you've set here.

If you have 10 word lists, and just one puzzle format with quantity 10, you'll get 100 puzzles
If you used "Merge All Word Lists", it counts as 1 single (large) word list. In that case you would get just 10 puzzles.

Creating the Puzzle Book - Manually

Another option to create a Word Search puzzle book (or any other type of puzzle) is to manually create puzzles that appeal to you visually. Puzzle Maker Pro will create a completely randomized new puzzle each time you click "Next Preview".

https://malcolm-en-gb.s3.eu-west-1.amazonaws.com/instances/wuGqS3zSeN/resources/sNPJzh5r1x/full%20page%20word%20search%20-%20manual%201.png (full page word search - manual 1)

Click "Next Preview" to generate a new puzzle
Optionally switch between Puzzle and Solution Preview, by clicking the "Preview Solution" option
Click "Save Preview", this will save the puzzle files in the project folder, exactly the same way it would be saved when you click "Create".

The next step would be to create the puzzle book from all the saved puzzles:

https://malcolm-en-gb.s3.eu-west-1.amazonaws.com/instances/wuGqS3zSeN/resources/IeL7BFWvau/full%20page%20word%20search%20manual%202.png (full page word search manual 2)

On the "Output Settings" tab you can find an option "Skip Puzzle Creation". When you switch this option on, and click "Create" (or "Create (TS)"), Puzzle Maker Pro will not generate new puzzles, but will only create the Powerpoint file or PDF from the existing puzzles in your project folder. (You have to make sure there are no additional puzzles or other files that you don't want to appear in the book).

What is a Preset

A Preset is basically the list of all the settings you can use for a puzzle. What is saved in a preset for Sudoku is different than for Word Search. In general, all the settings and options that are shown on the Puzzle Settings tab are part of it.

Time Saver Presets

In the Time Saver tab you can also find presets. These contain all the settings on the Time Saver tab (and sub-tabs) for that puzzle type. For example, for Sudoku, it will contain the entire table of sudoku variations and quantities. For Word Search it will include the word list and the table of puzzle sizes, along with the Main settings.

It is not required to use presets at all, but in some cases it can make your workflow more efficient.

Presets and Word Puzzles

A specific use case is when you generate word puzzles, such as Word Search: The word list you select for Word Search is part of the preset. When you 'load' that preset, you should see the same word list or word list file displayed.

When you use the Time Saver for Word Search, you can use select these (word search puzzle) presets to generate a puzzle book, and choose the option to use the word list that's included in that preset.

Please note: Puzzle Maker Pro supports different workflows. You don't have to use the presets, it's an option that may work for you.

Alternatively you can use a single preset for consistent styling of your puzzles, and use the Time Saver to override the word list.

Question 10

Getting Started with Checkerboard Sudoku

Accepted Answer

This tutorial applies to Puzzle Maker Pro - Checkerboard Sudoku.

Checkerboard Sudoku

Checkerboard is a sudoku variation with a specific grid setup: Like a checkerboard.

https://malcolm-en-gb.s3.eu-west-1.amazonaws.com/instances/wuGqS3zSeN/resources/FNWEI47XeO/Checkerboard%206x6.png (Checkerboard 6x6)

To solve a Checkerboard Sudoku, you apply the same rules as for regular sudoku, and additionally you have the Checkerboard rule: The white squares contain only odd numbers, the gray squares contain only even numbers.

This is a fun innovative sudoku variation. Because it's easier to solve - it has less options for each square - it's a great variation to include in activity books for children and adults.

Because Checkerboard Sudoku requires an even number of rows and columns in the grid, this variation is not available with a 9x9 grid.

Checkerboard Sudoku math

To compare the number of options of Checkerboard Sudoku with regular sudoku, here's the math for the first 3 squares in a 8x8 sudoku grid:

In a regular sudoku, you have 8 options for the first cell, 7 for the next, 6 for the next, and 5 different options for the fourth cell, which would be 8 * 7 * 6 * 5 = 1680 different options for the first 4 cells. (for a full grid, the math becomes increasingly more complex, and the number of options are bilions.

For Checkerboard sudoku, you have 4 options for the first cell: just 1, 3, 5, 7. Then 4 options for the next (2, 4, 6, 8). For the third and fourth cells there are only 3 options. For just the first 4 cells you have 4 * 4 * 3 * 3 = 144 options, which is less than 10% of the regular sudoku options. The difference gets increasingly larger when we add more cells.

Find Checkerboard Sudoku in Puzzle Maker Pro

To create Checkerboard Sudoku puzzles in Puzzle Maker Pro:

https://malcolm-en-gb.s3.eu-west-1.amazonaws.com/instances/wuGqS3zSeN/resources/uoaWRSeyqD/CheckerBoard%20Sudoku%20Overview.png (CheckerBoard Sudoku Overview)

Go to Sudoku Variations
Select one of the Sudoku Grid Sizes that are available for Checkerboard Sudoku (6x6, 8x8, 10x10, 12x12, 14x14, 16x16)
Select "Checkerboard" in the Variation menu.

There are quite a few tutorials about all the regular features of Sudoku in Puzzle Maker Pro, ranging from grid setup to symbol options, please check the tutorials below.

Note: Even though it's possible to use images for Checkerboard Sudokus, it doesn't make much sense, and the sudokus may be impossible to solve, since there are no odd and even images.
