Doku!

Every colored region on the board hides one dot. The symbols on each tile tell you where a dot cannot go.

Tap a square to pencil a note on it. Tap it twice to put a dot down.

THE DAILY

One board a day, the same board for everybody. Solve it and your streak goes up. The last seven days sit on the front page, so you can see which ones you got clean.

THE JOURNEY

150 levels across 11 chapters, from a 4x4 that teaches you one rule at a time to the 9x9 boards at the end. Three chances per level. Solve one in the fewest moves it can be done in and it is marked perfect.
