Sudoku Variants
Once you’ve mastered the logic of solving a standard sudoku puzzle, I suggest checking out one of these fun sudoku variants such as diagonal sudoku, jigsaw sudoku, picture sudoku, and word sudoku.
Sudoku rules for each variant are provided below. They are also typed at the top of each printable page.
Diagonal Sudoku Printable Puzzles
In a diagonal sudoku puzzle, all of these same rules apply as in a traditional sudoku puzzle, but there is one additional rule. The numbers must also be used exactly one time each along each main diagonal of the sudoku grid.
Jigsaw Sudoku Printable Puzzles
Jigsaw sudoku puzzles are a fun twist on the traditional sudoku puzzle.
The goal of a jigsaw sudoku puzzle is to complete the grid so that each row, each column, and each outlined irregular region contains exactly one of each number between 1 and n where n is the size of the puzzle. Numbers cannot be repeated in any row, column, or outlined irregular region.

Puzzle Solutions
Puzzle solutions are available on a password-protected solution page. I do not openly post the puzzle answer keys because one of my goals as a resource creator is to craft learning experiences for students that are non-google-able. I want teachers to be able to use these puzzles in their classrooms without the solutions being found easily on the Internet.
Please email me at sarah@mathequalslove.net for the password to the answer key database featuring all of my printable puzzles and math worksheets. I frequently have students emailing me for the answer key, so please specify in your email what school you teach at and what subjects you teach. If you do not provide these details, I will not be able to send you the password.
Not a teacher? Go ahead and send me an email as well. Just let me know what you are using the puzzles for. I am continually in awe of how many people are using these puzzles with scouting groups, with senior adults battling dementia, or as fun activities in their workplace. Just give me enough details so I know you are not a student looking for answers to the puzzle that was assigned as their homework!
