Tetrix is a classic game on www.flash-game.net in which your mission is to keep the blocks from piling up to the top of the playing field. To do this, you must move and rotate the tetrads as they fall, attempting to fit them together. If you can completely fill one horizontal line with colored squares, that line disappears and any filled squares above move down. If you is unable to fill lines completely, the tetrads 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. Good luck!
