The cars spin freely on their own axis the whole way down — where your weight sits decides how hard you whirl. Same track every time; never the same ride twice.
Physics as a slot machine. The Spider's cars rotate on free bearings, so the spin comes from wherever mass and momentum happen to land — seat position, cornering forces, luck. Coaster nerds call the genre a spinner; everyone else calls it 'the one where we came off sideways.'
About this model. The horizontal track path is derived from the community-traced centerline in OpenStreetMap (© OpenStreetMap contributors, ODbL). Elevation is a first-pass profile from published information; scan-accurate geometry lands over the off-season.
