Double Spiral is the 27th Expert stage in Super Monkey Ball 2, and the 56th Expert stage in Super Monkey Ball Deluxe. It also appears as the 166th Ultimate stage with continues, and the 206th without.
This stage features two slowly twisting spirals.
To get to the goal, go down the right, downward ramp, and immediately roll onto the twisting spiral as soon as it adjoins to the ramp because the other spiral does not have the goal. If you go across the left, upward ramp, then the goal will be upside down or not adjoined. Make your way across the spiral carefully with a lot of precision, so you will make it to the goal.
