Basic Terms File:25%.png

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

Block File:25%.png

---

The Block is a single square grid cell.

Tetra/Tetramino/piece File:25%.png

---

In Japanese or even in general common usage, the word "block" can refer to both Tetra piece or single grid cell. Another annoying fact, is that there is several syntaxe for the same word :

• Tetramino (TTC term)
• Tetromino (mathematical term)
• Tetrimino

To avoid confusion we will always use the short word Tetra from Greek witch mean "four".

4 blocks arranged into a shape give the tetra. There is 7 differents tetra, each one with a specific color. For concise description we are always refering to them by a single letter instead of color. TGM inherits its piece colors and rotation rules from Sega's 1988 arcade version of Tetris.

I, L, J, S, Z, T and O tetriminos.

Tetrion File:25%.png

---

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.

ARE File:75%.png

---

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.
