The Collapse games are popular online games. It is somewhat like Tetris in reverse. While Tetris has the bricks falling down, Collapse has a whole panel of bricks of different colors moving upwards. The aim of the game is to prevent the topmost brick from touching the ceiling. You achieve that by destroying the bricks. Simple? Not really. There must be three or more bricks of the same color for you to be able to destroy them. And as the skill-level increases, the game gets tougher. You need a sharp eye and a quick hand to play this game. But once you play, you’re hooked.
