A coaster having a rotatable track area capable of rotating, for example, 180° and repositioning a car for further movement along another track different than the one from which it originated. The rotatable track area can have a cross section of any polygonal shape. A corresponding rotation system with computer controls can selectively rotate the rotatable track area in predetermined increments according to the coaster track end positions so as to selectively align the rotatable tracks with the coaster tracks.
