This is the all time classic Free Online Tetris game. Blocks of different shapes will drop, rotate them and move them to stack up along the bottom of your screen. When a line is completely filled up, it will vanish, lowering the stack.
The goal of the Tetris game is to make all the blocks fit into each other, thereby keeping the blocks from stacking to the top which would end the game. Click the Play button to start the game. Press the UP arrow to rotate the falling objects, and press the DOWN, LEFT and RIGHT arrow keys to move them.
