Jigsaw Sudoku

Are you tired of Sudoku puzzles always being the same shape? If so, this is the game for you.

Jigsaw Sudoku, or irregularly shaped Sudoku puzzles, can never become boring. Each puzzle has a unique design which entices you to think differently and most certainly gets you to think 'out of the box'.

The "nonets" (3x3 boxes) have been twisted and take numerous shapes, similar to pieces of a jigsaw puzzle. All other Sudoku rules remain the same.

Created by Djape, a regular puzzle contributor to The Washington Post, Jigsaw Sudoku delivers 50 puzzles of various degrees of difficulty. Numerous features have been implemented to enhance the gaming experience: you can undo and redo as many moves as you like, get a hint or show errors. Further, you can enter "pencilmarks" which keep track of possible entries in each field. Finally, to help you get started in the solving process, you can use the "automatic pencilmarks" feature which enters number candidates for you.
