Top Spin

Construction
Passengers ride in a gondola suspended by large rotating arms rotating forwards and backwards, head-over-heels.

Other Information
It is a good idea to station a Handyman exclusively for a Gravitron, as its nausea ratings rival that of some roller coasters even on Beginners mode.

In RollerCoaster Tycoon 3, a Top Spin shoots water at the guests on the ride. Also, the different intensity modes were dropped.

This ride is called Top Spin in RCT2, RCT3, and the European version of RollerCoaster Tycoon. In the American version of RollerCoaster Tycoon, it is called "Graviton".
