These addictive and mind-boggling puzzles are for everyone. Su Doku is the symbolic logic puzzle that has taken Japan and the U.K. by storm. SuDoku Pro is PC software that you can download for free. It can generate millions of unique Su Doku puzzles that you can solve on your PC or print out to solve using pen and paper.

The maximum number of mathematically possible Su Doku puzzles is a really big number. Rest assured, it is definitely more than a million. SuDoku Pro can create that many genuinely unique Su Doku puzzles for you to solve, and more, in fractions of a second. Most Su Doku puzzles are 9Г—9 grids, but with SuDoku Pro, you can also experiment. Start at 4Г—4 grids, advance towards 16Г—16 grids, and eventually master even 25Г—25 grids. For each grid type, choose between three difficulty settings.

Print out a specific SuDoku Pro puzzle, or print as many puzzles as you like in batches: the choice is yours. Or print a half-solved puzzle for pen-and-paper completion while you are not at your PC.

Don't get lost when the going gets tough: SuDoku Pro can help you on your way with the Undo/Redo feature. It can also show you the solution to an incomplete Su Doku puzzle, or just give you that "one tiny hint" when you find you are really desperate.
