Spinning Platforms are gimmicks that only appear in the Topsy-Turvy Challenge Act in the console/PC version of Sonic Generations. Their main purpose is to serve as platforms that are somewhat harder to use.
Spinning Platforms vary in size, but keep the same general appearance. They are always seen from the side, since they only appear in the 2.5D side-scrolling sections. Although they are mainly red, they have a blue circle with a yellow star in the middle, similar to bumpers. Larger ones have a silver circle surrounding the blue circle. Yellow arrows on the red section of the Spinning Platform indicate which direction they are spinning.
Spinning Platforms are round platforms that spin so that the player must balance on them if he/she wants to stay on them. Most of the time, they are necessary to continue, and they usually spin in the opposite direction that the player is heading in order to slow down the player. An easy way to use these platforms is to jump quickly off them in the desired direction almost immediately after landing on them.
- Due their shape and appearance, Spinning Platforms are similar to Flywheels. Unlike Flywheels, the player cannot run or spin around Spinning Platforms.
