Garbage
From wiki
Garbage is a form of "attack" in multiplayer Tetris that has been around since the days of the Game Boy. The basic gist of it is that if you clear multiple rows of tetrominoes at one time, extra rows, with a gap will add to the bottom of your opponent's playfield.
[edit] Garbage System
The garbage system is simple. The more rows you clear at once, the more garbage rows are sent to your opponent.
| Clear Type | Rows Cleared | Garbage Rows Sent |
|---|---|---|
| Single | 1 | 0 |
| Double | 2 | 1 |
| Triple | 3 | 2 |
| Tetris | 4 | 4 |
| T-Spin Single | 1 | 2 |
| T-Spin Double | 2 | 4 |
| T-Spin Triple | 3 | 6 |
| Back-to-Back Bonus | 0 | +1 |
Some games will deviate from this. For example, sending more than one gap per row (Tetris The Grand Master Ace) or having 1:1 clear to send ratio (Super Tetris 3).
