The Original Swinger.
The Swinger, created by Dan Wolfe/The Amazing Earl and Buggy, is the world's first fully functionnal custom-made ride for the ROller COaster Tycoon series.
Guests swing around in little supended seats. The original Swinger has a few glitches. A second version of the Swinger was released to fix a number of bugs, increase the ride's guest capacity and improve the artwork. The original Swinger holds up to 9 riders, while the updated Swinger holds up to 18 riders. This ride and the Motocross ride were programmed by Buggy, with Amazing Earl providing the artwork.
Swinger Version 2.0.
Sadly, the ride isn't coded to allow the seats to swing according to G-Forces, as in a real ride.
