Line up blocks of the same color to make them disappear! Blocks fall down on the left side of the screen. You can use the arrow keys to move them around. However, watch out for blinking blocks. If you destroy one of them, they will raise the floor a level. This brings you closer to touching the top of the screen, which ends the game. Watch the meter in the upper right corner. When it is full, push the space bar to safely destroy the blinking blocks without making the floor go up. On the right side of the screen, look at the level objectives. Reach them to go to the next level.
