Logical

LOGICAL adds a distinctive puzzle game experience to the Game Boy Color. Each of the 99 levels starts with a unique arrangement of pipes and slotted gears. Balls of various colors roll through a pipe at the top of the screen, and they'll fall into the gear and pipe arrangement. The goal is to get balls of the same color to fill all of the slots of a gear. Once that happens, the balls disappear. But time is always a factor in doing this, so you've got to be efficient. As the game progresses, several complicating factors enter the mix: some pipes will only allow balls to travel one way, and other will only let balls of one color pass through. The biggest problem is that some levels require colors be removed in a particular order. Try to solve as many puzzles as you can with LOGICAL
