Gears is the 12th Expert floor in Monkey Ball and Super Monkey Ball, and the 21st Expert stage in Super Monkey Ball Deluxe. It also appears as the 131st Ultimate stage with continues, and the 171st without.
This stage consists of a row of spinning cogs, each with a decreasing number of teeth. The start and the goal are located on small platforms at the opposite ends of the row of cogs.
To get to the only goal, you must cross the bridge of gears. However, the time limit forces you to roll along at least two (three in Super Monkey Ball Deluxe) thin passages between the teeth of the gears.
