TETRIS GLOSSARY
VS score
Also called VS
TETR.IO's combined attack-and-defense performance measure. It reflects both sending and clearing garbage over time; it is not win rate, rank, or a universal measure of Tetris skill.

APM →
Garbage attack generated per minute, not keyboard actions per minute. Whether cancelled attack is included depends on the game's statistic; compare values within the same ruleset.
Downstacking →
Clearing down through an existing stack or garbage to reach lower gaps. Look at the gap below your next clear and avoid covering it with blocks that survive the clear.
