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.

This ride is called Top Spin in both RCT2 and RCT3.
