Navigate the mazes in order to eliminate all the numbers. Simple math makes for great obstacles. Use arrow keys to move the red piece through the maze and to collect and eliminate all of the numbers. Each time you move the red onto a number it will absorb it. Absorbing a smaller number increases your number and absorbing other numbers leaves you with a difference. Doors, passageways and bonuses add to the fun challenge. 4 Bonus levels can be unlocked after the main 25 levels are completed.
