Rotation system 25%.png

The TGM series use several rotation system but the primary is the Arika Rotation System (ARS). TGM1 and TGM2 shares same ARS system. TGM3 have two distinct system named Classic (extended ARS) and World (SRS). TGM ACE propose three systems SRS, ARS1 and ARS2.

The ARS inherits its tetramino colors and rotation rules from Sega's 1988 arcade version of Tetris, and expands it by including compensations (wall-kicks), allowing pieces to rotate in tight spots. See TGM Rotation for further explanation.
