Inverted

   Inverted coasters were a breakthrough in the roller coaster universe. an inverted coaster hangs from the track. the first kind of coaster that hung from the track was a suspended coaster. from there, designers like B&M, Vekoma, and Intamin AG. made true inverts that could loop ang go upsidedown, dubbing the titile an SLC(suspended looping coaster). SLC and inverts have been very popular in parks lately and many people like them.

   Floorless

   Floorless coasters are ment to give you the same feeling as an Invert except above the track. Only done by B&M, th floorless coaster is pretty self-explanitory and are very demanding and popular in the industry right now. The floorless coaster deduted in 1999 at Six Flags Great Adventure. The coaster was given the name  Medusa. Two of B&M's Dive Machine coasters (coasters that dive straight down at a vertical angle) have floorless trains.

Stand-Up

   In the year of 1984, Togo industries released King Cobra, the world's first stand-up coaster located at Kings Island. The Togo models are pretty hard to find anymore and the B&M models are more common. AS the name suggests, the stand-up coaster is a coaster were you are standing on your feet throughout the majority of the ride.

Flying

   First introduced by Vekoma as Stealth (now relocated at Carowinds as BORG Assimilator), the flying coaster is ment to give you the feeling as though you were flying. Flying coasters are mainly done by Vekoma and B&M and are very popular. In 2005, B&M unleashed Tatsu at Six Flags Magic Mountain, a massive flying coaster soaring about a hundred feet off the ground for most of the flight.

4-Dimensional

   If you thought the flying coaster was cool, wait untill you see this. In the early 2000s, Arrow Dynamics summoned X. X is what you would call a 4-Dimension coaster. at the time there was only one but X now has a sister in Japan known as Ejainaika. X was, and still is, a break through in the coaster universe. THin one of a kind coaster isn't normal, as traveling along the track X as another set of raila that maneuvers the seats to turn up to a full 360 degrees. It also introduced its own OTSR(over the shoulder restraints) system, along with quite a few new elements. No matter how many roller coaster you have ridden, you have never experienced anything like this.
