RULES: Steer the blocks using your keyboard's arrow keys (left/right). Down key causes block to fall faster. 4 sizes of colored building blocks drop. You win points and even earn back lost lives, as long as you stack the blocks properly -- in exact order of decreasing size (or same size). All blocks disappear on a platform when you build a complete pyramid. You can also drop the smallest block on empty platform to gain points. Fail to properly place a block and you lose a life. Have fun! [more games] Please report technical problems
