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)
 * Arika Rotation System (or ARS)
 * Sega Rotation System
 * Nintendo Rotation System
 * DTET Rotation System
 * Any rotation system created in NullpoMino due to its various customizations offered for the 28 rotation stages and the wallkicks (only built-in wallkick settings, you cannot add or remove wallkick settings (one of the very few cases of NullpoMino not being customizable)).
 * Tetris Best rotation system (or TBRS), very flexible
 * Tetris Best 2 rotation system (or TB2R), only has floorkicks
 * Tetris Perfect rotation system (or TPRS), condemned
 * Tetris Return rotation system, approved version of the above, as side 3-kick tests were moved behind up to 2 floorkicks
