This Sonic-themed block game will keep your brain churning. You have to place the blocks as they fall to create full lines. Once you create a full line, it will disappear. As a block falls, click the up key to rotate it and make it fit with the pieces that are already placed. Be careful about letting any one line get too high. If any line touches the top of the screen, the game is over. Your objective is to clear the screen as quickly as you can. Dr. Robotnik will fly onto the screen occasionally to try to mess your game up!
