Spiral is the 26th Advanced floor in Monkey Ball and Super Monkey Ball, as well as the 55th Advanced stage in Super Monkey Ball Deluxe. It also appears as the 95th Ultimate stage with continues, and the 115th without. It is given a 5 out of 10 difficulty rating.
It begins with a long bridge leading to a path jutting off to the left and the entrance to the spiral at the right (the path at the left serves as a run-up). The spiral descends slowly and ramps to the center, meaning that the player must go fast to keep enough centripetal force to stay on the path (incidentally, similar to the level Centrifugal). The path at the beginning has some bananas, and a banana bunch sits behind the goal, which can be reached if the goal is crossed fast enough.
