The objective of the game is to remove all blocks from the board by selecting the largest groups of stones with the same color. You can remove blocks with same color that are touching each other vertically or horizontally.
The score is calculated as follows: (n-1)*(n-1), where n is the number of removed blocks at one time. Bonus is added if the board is completely cleared. The bonus added is the size of the board (e.g. 81 on easy level).
High score can be sent to the server from your phone.

Undo movement is also supported. The game keeps the history of block removals. You can always go back to a previous state of the game if a piece has been removed accidentally. Shortcuts are helping to access the frequently used commands. You may undo with the star key or create a new game with the pound key.
