What is Multi Sudoku?
Multi sudoku is a general term for any sudoku puzzle that has more than one grid. The grids can overlap in various ways, creating different shapes and patterns. The most common types of multi sudoku are:
Samurai sudoku: This is a multi sudoku with five grids, arranged in a cross shape. The four corner grids are 9x9, and the central grid is 9x9 as well, but it overlaps with the other four grids by 3x3.
Double sudoku: This is a multi sudoku with two grids, overlapping by 3x3 or 4x4.
Triple sudoku: This is a multi sudoku with three grids, overlapping by 3x3.
Quad sudoku: This is a multi sudoku with four grids, overlapping by 3x3.
There are also other types of multi sudoku, such as windoku, hypodoku, butterfly sudoku, flower sudoku, and so on. Each type has its own rules and characteristics, but they all share the same basic principle: each grid must be solved according to the standard sudoku rules, and the overlapping regions must be consistent across all grids.
The History of Multi Sudoku
The origin of multi sudoku is not clear, but it is believed that it was inspired by the original sudoku puzzle, which was invented by Howard Garns, an American architect and freelance puzzle constructor, in 1979. He called it Number Place, and it was first published in Dell Magazines in the US.

The puzzle became popular in Japan in the 1980s, where it was renamed as sudoku, which means "single number" in Japanese. It was then introduced to the rest of the world in the early 2000s, thanks to Wayne Gould, a retired Hong Kong judge who developed a computer program to generate sudoku puzzles.
The first multi sudoku puzzle was probably created by Nick Deller, a British puzzle designer who published a samurai sudoku in The Times in 2005. Since then, many other types of multi sudoku have been developed and published in various newspapers, magazines, books, websites, and apps.
The Benefits of Playing Multi Sudoku
Playing multi sudoku can have many benefits for your brain and your mood. Here are some of them:
It improves your logic and reasoning skills. Solving multi sudoku requires you to apply deductive reasoning and eliminate possibilities based on the given clues. You also need to use spatial awareness and pattern recognition to visualize the grids and their overlaps.
It enhances your memory and concentration. Solving multi sudoku requires you to remember the numbers and their positions in the grids and their overlaps. You also need to focus on the puzzle and avoid distractions.
It reduces your stress and anxiety. Solving multi sudoku can be a relaxing and enjoyable activity that can help you calm your mind and release tension. It can also boost your mood and self-esteem by giving you a sense of achievement and satisfaction.
It prevents cognitive decline and dementia. Solving multi sudoku can keep your brain active and healthy, especially as you age. It can stimulate your brain cells and prevent them from degenerating. It can also delay the onset of Alzheimer's disease and other forms of dementia by improving your mental agility and flexibility.
The Different Types of Multi Sudoku
As mentioned earlier, there are many types of multi sudoku, each with its own rules and characteristics. Here are some examples of the most popular ones:
Type
Description
Example
Samurai sudoku
A multi sudoku with five grids, arranged in a cross shape. The four corner grids are 9x9, and the central grid is 9x9 as well, but it overlaps with the other four grids by 3x3.
Double sudoku
A multi sudoku with two grids, overlapping by 3x3 or 4x4.
Triple sudoku
A multi sudoku with three grids, overlapping by 3x3.
Quad sudoku
A multi sudoku with four grids, overlapping by 3x3.
Windoku
A multi sudoku with four extra 3x3 regions marked by thicker lines. The numbers in these regions must also be unique.
Hypodoku
A multi sudoku with four extra 3x3 regions marked by dashed lines. The numbers in these regions must also be unique.
Butterfly sudoku
A multi sudoku with four grids, arranged in a butterfly shape. The two upper grids are 9x9, and the two lower grids are 6x6, but they overlap with the upper grids by 3x6.
Flower sudoku
A multi sudoku with six grids, arranged in a flower shape. The central grid is 9x9, and the five petal grids are 6x6, but they overlap with the central grid by 3x6.
How to Play Multi Sudoku
The basic rules of multi sudoku are the same as regular sudoku: you have to fill in the empty cells with numbers from 1 to 9 (or 1 to 6 for some smaller grids), so that each row, column, and 3x3 region (or 2x3 or 3x2 for some smaller grids) contains each number exactly once. The difference is that you have to do this for more than one grid, and you have to make sure that the overlapping regions are consistent across all grids.
For example, if you have a samurai sudoku, you have to solve five grids at the same time, and the central grid overlaps with the four corner grids by 3x3. This means that the numbers in the overlapping regions must be the same in both grids. For example, if the top-left cell of the central grid is 5, then the bottom-right cell of the top-left grid must also be 5.
To play multi sudoku, you need to use a combination of logic and trial and error. You can start by looking for clues in the given numbers, such as singles, pairs, triples, and so on. You can also use techniques such as scanning, marking, elimination, and grouping. You can find more details about these techniques in this [guide].
However, sometimes you may encounter situations where you have to guess or make assumptions. This is especially true for harder puzzles or puzzles with fewer clues. In this case, you can use pencil marks or notes to keep track of your possibilities and test them out. If you find a contradiction or an error, you can backtrack and try another option.
The Tips and Tricks for Solving Multi Sudoku
Solving multi sudoku can be challenging and frustrating, but it can also be rewarding and fun. Here are some tips and tricks that can help you improve your skills and enjoy the game more:
Start with the easiest grid. Usually, this is the grid with the most clues or the smallest size. By solving this grid first, you can get more information and eliminate more possibilities for the other grids.
Focus on the overlapping regions. These are the key areas that connect the grids and affect each other. By filling in these regions first, you can create more opportunities and constraints for the other regions.
Use colors or symbols to mark your candidates. This can help you visualize and organize your options better. For example, you can use different colors for different grids, or different symbols for different types of candidates (such as singles, pairs, triples, etc.).
Check your progress frequently. This can help you avoid mistakes and spot errors early. You can use online tools or apps that can check your answers and highlight your mistakes. You can also use logic or math to verify your solutions.
Take breaks and relax. Solving multi sudoku can be mentally exhausting and stressful, so it is important to take breaks and relax your mind. You can do something else that you enjoy, such as listening to music, reading a book, or playing another game. You can also stretch your body and drink some water to refresh yourself.
The Common Mistakes to Avoid in Multi Sudoku
Solving multi sudoku can also be prone to errors and mistakes, especially if you are not careful or attentive enough. Here are some common mistakes that you should avoid when playing multi sudoku:
Ignoring the overlapping regions. This is one of the most common and fatal mistakes that can ruin your puzzle. If you forget or neglect the overlapping regions, you may end up with inconsistent or impossible solutions.
Mixing up the grids or regions. This is another common mistake that can cause confusion and frustration. If you mix up the grids or regions, you may end up with wrong numbers or misplaced candidates.
Overlooking clues or candidates. This is a mistake that can make your puzzle harder or unsolvable. If you overlook clues or candidates, you may miss opportunities or constraints that can help you solve the puzzle.
Guessing randomly or blindly. This is a mistake that can waste your time and energy. If you guess randomly or blindly, you may end up with contradictions or errors that can force you to start over.
Not checking your answers or solutions. This is a mistake that can prevent you from completing or enjoying your puzzle. If you do not check your answers or solutions, you may not notice your mistakes or errors until it is too late.

FAQs
Here are some frequently asked questions about multi sudoku:
Q: How hard is multi sudoku?
A: The difficulty of multi sudoku depends on several factors, such as the type of multi sudoku, the number of grids, the size of the grids, the number of clues, and the level of complexity. Generally speaking, multi sudoku is harder than regular sudoku because it involves more grids and more constraints. However, some types of multi sudoku may be easier than others. For example, double sudoku may be easier than samurai sudoku because it has fewer grids and less overlap.
Q: How long does it take to solve a multi sudoku puzzle?
A: The time it takes to solve a multi sudoku puzzle depends on several factors, such as your skill level, your experience, your strategy, your speed, and the difficulty of the puzzle. Generally speaking, multi sudoku puzzles take longer to solve than regular sudoku puzzles because they involve more grids and more constraints. However, some types of multi sudoku puzzles may take less time than others. For example, windoku may take less time than samurai sudoku because it has fewer grids and more clues.
There is no definitive answer to how long it takes to solve a multi sudoku puzzle, but you can estimate it by using this formula: time = (number of grids x number of cells x difficulty factor) / (speed factor x experience factor). For example, if you are solving a samurai sudoku puzzle with 369 cells and a difficulty factor of 3, and you have a speed factor of 2 and an experience factor of 1.5, then the estimated time is: time = (5 x 369 x 3) / (2 x 1.5) = 1845 / 3 = 615 seconds or about 10 minutes.
Q: What is the difference between multi sudoku and jigsaw sudoku?
A: Multi sudoku and jigsaw sudoku are two different types of sudoku variations. Multi sudoku is a type of sudoku that consists of more than one grid, overlapping each other in different configurations. Jigsaw sudoku is a type of sudoku that has irregularly shaped regions instead of the standard 3x3 regions. Jigsaw sudoku can also be considered as a type of multi sudoku, if it has more than one grid. For example, jigsaw samurai sudoku is a type of multi sudoku that has five grids arranged in a cross shape, with irregularly shaped regions in each grid.
Q: How many solutions does a multi sudoku puzzle have?
A: A multi sudoku puzzle should have only one unique solution, just like a regular sudoku puzzle. However, some multi sudoku puzzles may have more than one solution, either by design or by mistake. This can happen if the puzzle is not well constructed or if it has too few clues or too many symmetries. A multi sudoku puzzle with more than one solution is considered invalid or unsolvable.
Q: How do I create my own multi sudoku puzzle?
A: Creating your own multi sudoku puzzle can be a fun and creative activity. You can use online tools or apps that can generate multi sudoku puzzles for you, or you can create them manually by following these steps:
Choose the type and size of your multi sudoku puzzle. For example, you can choose samurai sudoku with five 9x9 grids.
Draw the grids and the overlapping regions on a paper or a computer program. Make sure that the grids are aligned and that the overlapping regions are consistent.
Fill in some numbers in the grids randomly or according to a pattern. Make sure that each grid follows the standard sudoku rules, and that the overlapping regions are consistent across all grids.
Remove some numbers from the grids to create clues. Make sure that there is only one unique solution to the puzzle, and that there are enough clues to make the puzzle solvable.
Test your puzzle by trying to solve it yourself or by using online tools or apps that can check your solution.
