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.
