A German family-owned manufacturer from Waldkirch, the company behind Europa-Park and producers of water rides, dark rides, and acclaimed hyper coasters.

Point-of-view footage filmed from the front row of a coaster, letting prospective riders virtually preview the full experience.

An Idaho-based manufacturer that invented the hybrid coaster concept, converting ageing wooden coasters into steel I-box track rides with unprecedented airtime and inversions.

A legendary German manufacturer whose classic looping coasters from the 1970s and 80s remain beloved across European parks for their smooth, intense ride experience.

A coaster where cars rotate freely on a vertical axis throughout the ride, so every run offers a different orientation.

A situation where multiple coaster trains accumulate in the brake run because the station is not clearing fast enough — reducing throughput and extending wait times.

A roller coaster enhanced with VR headsets displaying a synchronised virtual experience that overlays the physical ride.

A coaster type with seats extending on either side of the track, so riders have nothing above, below, or beside them — maximising the sensation of flight.

The sensation of weightlessness or being lifted from your seat caused by negative G-forces on roller coasters.

A hill-shaped element engineered to produce negative G-forces, causing riders to float or be lifted from their seats.
