The game is to erase lines by shooting and moving the 7 types of blocks that fall on the screen. The more lines you erase at once, the higher score you get. Although the rules are simple, the game requires advanced strategy and good shooting skills. Players use their brains and reflexes to figure out which blocks to place where, when to erase lines, and how to stack them. Experience the fun of stacking blocks and erasing them all at once!
