Master Floor 9 (Bridge Master in Super Monkey Ball Deluxe) is the 9th Master stage in Super Monkey Ball, and the 19th Master stage in Super Monkey Ball Deluxe. It is also the sole Master stage in the original Monkey Ball.
The stage is a series of thin, winding platforms that coil in several directions. The path goes from fairly difficult to insanely difficult, not to mention two crucial turns the monkey must make to the goal. At the very end is the goal.
There is only a Blue Goal in this level. (It is colored tan like in other Master stages.)
Similar to Curvature, you must keep your balance as the path becomes thinner as you go along the platform. It's best to be careful the whole way through.
- In Monkey Ball, the arcade version of this game, this level was the only Master level in the game. Instead of "Master 9," it was simply called "Master" and was labeled as "Final Stage".
- Bridge Master has been noted as one of the hardest stages in Monkey Ball history, along with Stamina Master from Super Monkey Ball, Helix from Super Monkey Ball 2 and Ultra Heaven 5 from Super Monkey Ball: Banana Blitz.
