Rotation system 25%.png

Main article: TGM rotation

The TGM series uses various rotation system but the primary one is the Arika Rotation System (ARS). TGM1 and TGM2 both use ARS. TGM3 has two distinct systems used in Classic (extended ARS) and World (SRS). TGM ACE uses three systems SRS, ARS1 and ARS2.

ARS inherits its tetromino colors and rotation rules from Sega's 1988 arcade version of Tetris, and expands it by implementing wall kicks, which allow pieces to rotate in tight spots.
