This game will have you addicted in seconds. Your task is to remove a group of two or more tiles from the board. What's the catch? Well, each group of two or more tiles has to be the same color.
This application comes in grayscale and color. It looks spectacular on the color version. A key point to getting a high score is to try and get as many removed as possible. To remove the tiles from the screen, simply click on one of the tiles and the connecting tiles will get an explosion symbol on them. If you want to proceed with the deletion, click again.
