Other Sudoku Variations You Can Try

Four of the many other Sudoku variations are the Mini Sudoku, Mega Sudoku, Irregular, Sudoku, and the Multi Sudoku. Compared to the classic 9×9 Sudoku puzzle, these variants may have grid sizes other that the 9×9 size. They may also have additional rules that can only be applicable to their type. Take a closer look at these 4 variants that you might also like to work on.


Completing a Mini Sudoku puzzle by seeing to it that each number should only appear once in every row, every column, and every sub-square is still the primary goal for each player. Mini Sudoku, however, is smaller in grid size compared to the classic 9×9 Sudoku that you most often see. This particular Sudoku variant may either have a 4×4 or a 6×6 grid size.

This means that when you are playing a Mini Sudoku Puzzle with a 4×4 grid size, you should place the numbers 1 to 4 to their corresponding row, column, and sub-square without having any duplicates in any of those three places. Completing a 6×6 grid Mini Sudoku puzzle also goes like that; you must make sure that each row, each, column, and each sub-square only contains a single number from 1 to 6.

Mini Sudoku is especially good for beginners. This is due to its fewer set of numbers that makes it easier and faster to solve.


Mega Sudoku may either have a 12×12 or a 16×16 grid size. It is larger compared to the classic 9×9 Sudoku puzzle in terms of grid size. Just like in any Sudoku puzzle, the main aim is to fill those unfilled boxes with numbers 1 to 12 (for the 12×12 grid) and 1 to 16 (for the 16×16 grid) and making sure that each number only appears once in every row, every column, and every sub-square.

As you may be aware by now, Mega Sudoku has a larger grid size compared to the classic 9×9 Sudoku. This means that completing this particular Sudoku variant may cause you a longer period of time. Its level of difficulty, however, still rests on how the givens are prearranged.


The first thing that you will note in an Irregular Sudoku puzzle is the shape of its sub-squares. If you try to think about it, it is more applicable to call them “regions” rather than sub-squares since most of them are not really squares. But for this purpose, let us just retain the word sub-squares instead of regions. Just like in other Sudoku puzzles, you are still not allowed to repeat any number inside every sub-square, every row, and every column.

Irregular Sudoku puzzles may have three different grid sizes (6×6, 9×9, or 12×12). Each row, column, and sub-square should posses only one number ranging from 1 to 6 (for the 6×6 grid), from 1 to 9 (for the 9×9 grid), and from 1 to 12 (for the 12×12 grid).


If you are looking for a more complex Sudoku variant, then Multi Sudoku is right for you. Multi Sudoku does not only have a single grid but has multiple grids from different Sudoku variants. Because it has more than one variant, it also carries more than one variant rules.

In Multi Sudoku, you will encounter a Sudoku sheet that carries two or more overlapping Sudoku grids. These overlaps can be seen on certain sub-squares which must be solved with two variant rules from each main grid. The goal here is still the same which is completing the puzzle without having a single number appear more than once in each row, column, and sub-square. This is one of the most complex and challenging Sudoku variants that you could possibly try to solve.

Test yourself by trying these Sudoku variations and try to complete them while having fun.
