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 tetrimino 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.

Parameters 25%.png

Aside from fall speed, the speed of gameplay in TGM is basically determined by the following 4 parameters. The names given here are unofficial, as no official names are known.

Name Description
Appearance Delay (出現時間 - shutsugen jikan, ARE) The frames between a last block locked to a new block appears. Is this called for 'ARE'? while this time, players can input actions for shift / IRS.
Delayed Auto Shift Delay (横溜め時間 - yokotame jikan) The frames to delayed auto shift. When holding left or right during the specified frames, horizontal movement is faster. It will move 1 row per frame.
Lock Delay (接着時間/固定時間 - setchaku jikan or kotei jikan) The number of frames until a piece locks down and it can't be moved or rotated. If the altitude of the piece changes, the lock delay countdown will be reset.
Line Clear Delay (消去時間 - shoukyo jikan) The animation frames of line-clearing animations. during this time, the game accepts input for DAS / IRS / IHS.

¹Will likely turn out to be vaporware, as the same issue existed for TGM4's 2nd test under the name TGM2015, so it will be unreleased for as long as TTC owns the rights to Tetris.
