Basic Terms
There is a lot of appelation standard on Tetris Games and TGM have interesting specification. To avoid confusion we list here the basic.

Block
The Block is the smallest square shape in Tetris Game.

Tetrimino
4 blocks arranged into a shape give the tetrimino. There is 7 differents tetriminos, each one with a specific color. For concise description we are always refering to them by a single letter instead of color. Tetriminos are often also called "piece" or "tetra" and sometimes "block" (as show on 2ch.net) but for this last appelation it can be confusing.

Tetrion
Sometimes called the "outfit Frame" or more simply the "box that surround the game". Certainly you have never hear about this word but this is the official name given by the TTC. You will also never use it but i just mension it for avoiding confusion with the next definition.

PlayField
The playfield is surrounded by the tetrion. The standard size is fixed to 10 blocks length and 20 blocks height.

Stack
Stack definition.

StackFall
StackFall definition.

Row
Row definition. do we add entry for double and triple ?

Tetris
Tetris definition. To erase 4 lines.

Combo

Frame
Frame definition.

Step
Step definition.

Move/shift
Move definition.

Rotation
Rotation definition.

Delayed Auto Shift (DAS)
DAS definition.

Gravity Unit (G)
Gravity definition. it shows [drop lines / frame]. TGM field's height is 20, so max is 20G.

Drop
Drop definition.

Sonic Drop
Sonic Drop definition. force landing a current block.

lock Delay
Lock Delay definition.

Initial Rotating System (IRS)
IRS definition.

Temporary Landing System (TLS)
TLS definition.

Level

LevelStep
LevelStep definition. Normally the level increases by a block appearing, but if the level is x99(like 099, 199, ...) then we can increase Level only to erase lines.

Grade Recognition System (GRS)
GRS definition.

Arika Rotating System (ARS)
ARS definition.

Super Rotating System (SRS)

ARE
ARE is the period of time between the lockdown of the previous piece and the appearance of the next piece. Depending on the level, the amount of ARE may shorten.


 * During ARE : During ARE, the player must wait for the next piece to appear, and cannot actively cause anything to happen. However, ARE serves as a time for the player to input DAS, IRS and IHS actions which will be processed in the moment ARE finishes and the next piece appears.


 * Word Origin : ARE is a word of Japanese origin, and though it looks like an acronym, it does not stand for anything. It derives from the Japanese word, "あれ (are)," pronounced "a ray" quickly. The word "あれ" is a demonstrative pronoun, literally translating to "it" or "that". Japanese players originally referred to this in-between time using the word "あれ" as there was no good word to describe it. The capital letter alphabet form "ARE" (pronounced ay arr ee) became popular when someone wrote it in that form, possibly owing to its cooler, acronym-like look.


 * The Existence and Lack of ARE : ARE is a vital gameplay factor in TGM, as its existence allows for many systems like 20G, DAS, IRS and IHS to exist. They do not exist, however, in popular American versions such as Tetrinet and most Tetris Worlds-compliant games. It is debated whether the lack of ARE is a requirement in the World guidelines or not; TGM3 (Ti) and TGMA in particular, do have ARE even though they seem to follow the guidelines.
