Instantly familiar, refreshingly different.

Rediscover your love for Sudoku with this fun new variant - just drag and drop the pieces to complete.

Be warned, though, that you will have to engage your brain to figure out how Jidoku piece shape complements and extends all that Sudoku logic you already know...

Just like in our popular Killer Sudoku app, Jidoku contains hundreds of free puzzles with multiple sizes and difficulties, plus a validation feature to check progress.
