Category:Rotation systems

A rotation system broadly represents where and how tetrominoes spawn, how they rotate, and what wall kicks they may perform. Different rotation systems exist through a broad spectrum of games, some having their own unique system, others in a series may change only a little. Notable systems:
 * Original Rotation System, used by the first Tetris games. Also called ORS.
 * Super Rotation System (or SRS)
 * In Tetris at tetris.com, due to the nature of the mouse movement, it is possible to get 3-kicks, 180, and O rotation.
 * Arika Rotation System (or ARS)
 * Sega Rotation System
 * Nintendo Rotation System
 * DTET Rotation System
