The term Giga Coaster was coined by Cedar Fair and Intamin AG to describe their world record breaking ride: Millennium Force. This coaster was built in May 2000 and was the first coaster to go over 300 feet in height. Essentially, any full circuit coaster between 300 feet and 399 feet (91.4m-121.6m) should be classified as a Giga Coaster.
