Numbered gears, number changing paddles, and a factor full of both make for a game that never has a dull moment. The objective is to get the most points possible. The way you earn points is by matching the number on the paddle with the number on the gear that is falling. Don't worry, because if you're quick enough you can bounce the gears until you select the appropriate number. The mouse is used to move the paddle left and right and the left mouse click is used to change the number. Keep at it, because each level gets faster and produces more gears.
