At first look, you sinply have to dock tetromino-like pieces into the board: once you fill in a vertical or horizontal line, it will disappear.
But, unlike other similar games, there are special blocks (bombs, magnets, arrows) that can help you (or not) during your quest to keep on playing.
There are dozens of levels, starting from easy to extremely hard.
Your goal is to dock all bricks of each level until none remains. You have 3 lives per level, and you loose a life of you come up to a dead end.
Complete a level without loosing a life to get a 5 star rating.
