Brick Tetris

Shapes called Bricks fall, one at a time, from the top of the playing field to the bottom. Bricks are comprised of 4 squares arranged into 7 different patterns. The object of the game is to keep the blocks from piling up to the top of the playing field. To do this, the player must move and rotate the Bricks as they fall, attempting to fit them together. If the player can completely fill one horizontal line with colored squares, that line disappears and any filled squares above move down. If the player is unable to fill lines completely, the Bricks will stack up and eventually reach the top of the playing field. The game ends when a new tetrad that is placed at the top of the playing field is unable to drop at all due to the filled blocks.

NOTE: To help the skilled player plan better moves, the next board to fall is typically shown somewhere on the screen. Which blocks appears next is determined by a random number generator.
