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.

Garbage System

The garbage system is simple. The more rows you clear at once, the more garbage rows are sent to your opponent.


General Garbage System in Guideline Games
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).

Gameplay Example

The left diagram shows the player's field while the right shows his opponent.

If a player drops a "T" here:








ttt
t





jjjl
jsslooj
ssjjlzooj
ggggggggg
ggggggggg
ggggggggg
ggggggggg
ggggggggg
















l
lllsjj
izzssjoo
izzsjoo
ijlllttt
ijlsstttt
jjssiiiit

It will clear two lines at once, sending one row of garbage to the opponent:

















jjjl
ggggggggg
ggggggggg
ggggggggg
ggggggggg
ggggggggg















l
lllsjj
izzssjoo
izzsjoo
ijlllttt
ijlsstttt
jjssiiiit
ggggggggg

Then, if the player drops a tetris here:






i

jjjl

ggggggggg

l

izzssjoo
izzsjoo

jjssiiiit
ggggggggg

It will clear four lines at once, sending four lines of garbage to his opponent.

Garbage In-Depth

Games with random garbage, like Tetris Worlds, will mathematically output two aligned garbage holes (an easy double) 1:10 garbage lines, three aligned every 1:100, and four aligned every 1:1000.

Some games, like Tetris DS feature semi-random garbage output. With random garbage, the player will receive at least a double's worth of aligned holes 10% of the time. Empirical data suggests Tetris DS leans closer to 72%.

Early games like Tetris (Game Boy) will switch the garbage's hole column every nine rows or so.

Some players prefer pure random garbage because aligned garbage tends to "see-saw" back and forth wildly. Others enjoy the depth and challenge presented by random garbage.

Tetris Worlds is currently the only game which lacks retaliation garbage, meaning clears from garbage will not send back any garbage. Because of this, clearing garbage becomes less desirable, which a player may argue deprives the game of some depth.
