The player controls the Kloaster, a space vessel that acts as the game's paddle which prevents a ball from falling from the playing field, attempting to bounce it against a number of bricks.

The ball striking a brick causes the brick to disappear.

When all the bricks are gone, the player goes to the next level.

There are a number of variations (bricks that have to be hit multiple times, flying power-ups, etc.).

This game is a classic game with a lot of variations. Kloaster is now available for IOS.
