SameColors

The objective of the game is to remove all blocks from the board by selecting the largest groups of pieces 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).
