Your mission is to remove all tiles from the board. Each tile represents a colored ball and you have to blend some of these balls to generate a couple of like-colored balls. A tile can be removed only if it isn't blocked by other tiles - like mahjong solitaire games. Click to remove a pair of tiles of the same color. If there is no tile of the color you need, you may create one by blending two tiles and getting their mid-tone as a target color. Have fun!
