The rules are easily explained - the fun can begin - NO ADS!

Place differently shaped tiles on a Sudoku board and try to fill a row, a column or one of the nine squares completely to remove these blocks. To make it a challenge, the tiles cannot be rotated or mirrored.

As soon as no tile can be placed on the board, the game is over.

If you can fill more than one row, column or square at once, you get extra points. If you remove multiple blocks in consecutive moves, you also get extra points. Challenge your own highscore, create new strategies to place the tiles and compare your scores with your friends.

Three tiles are always unveiled at once. So, you need to plan ahead and leave suitable areas empty so that you can still place the upcoming tiles on the board.

If the starting difficulty level gets too easy, try one of the harder settings. These increase the probability for tiles which are harder to place.

The hardest difficulty level already starts with randomly distributed blocks on the board.
