Spudoku

Solve the puzzles on your device by dragging colors into place, or set up and solve them on a ColorKu board.

Puzzle difficulties range from EasyPeasy to Wicked, and the layout or symmetry of the puzzle can be selected.

Of course you get the solution, too.

And if you get stuck, Spudoku can give you a hint.
