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
