Try and remove all of the blocks from the screen. Sounds easy doesn't it! But you can only remove blocks of the same type if there are two or more next to each other and the more blocks of the same type that you remove the higher they score. With skillful play you can really crank up your score.
There are three great game modes with lots of themed levels (including outer space which has space related blocks, backgrounds and layouts) which also feature blocks with special powers.
