Gravity →
Automatic downward movement. In timing discussions, 1G means one cell per simulation frame. Gravity controls falling speed; lock delay controls how long a landed piece can remain adjustable.
Score →
The game's reward total for actions such as clears and drops. It is separate from garbage attack. The same placement can earn different points in different games, modes or levels.
