If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
Clear the board by clicking groups of three or more cubes.
Groups are connected cubes of the same color.
The more cubes you can crush with one click, the higher your score will be. Each level the required amount of cubes, you need to crush, to reach the next level will increase. Have fun!
This game is played with mouse only.
