Description from the publisher
Collapse groupings of like-colored cubes - to prevent these cubes from filling the entire game screen you must burn blocks of three or more one-coloured cubes. Each further level demands you to be faster and faster. When cubes fill the entire game screen the game is over. So be attentive, quite accurate and as fast as you can. Larger groupings mean more points and very large groupings earn bonuses to compound your score even further.
