SuDoku MegaBooks
MegaBooks are
Virtual Puzzle Books that contain every SuDoku puzzle that appears on the
Puzzles page of this website.

The MegaBook may be updated at any time to collect all the puzzles that have been published so far (using the Solver's 'Download' button).
So the MegaBook keeps growing! At the beginning it will contain just a few puzzles and as time goes by it gains new puzzles as they appear on the website. Each month there are 9 new puzzles:
- 1 Beginner SuDoku
- 1 Easy Sudoku
- 1 Tricky SuDoku
- 1 Difficult SuDoku
- 1 Challenging SuDoku
- 1 Ultimate SuDoku
- 1 Killer SuDoku
- 1 Picture SuDoku
- 1 Variant SuDoku
MegaBook 2021 Plus (now complete with 432 puzzles in total!) and
MegaBook 2025 Plus (still growing) may be purchased
here.
