Setup
Also called Pattern · Shape
A deliberate arrangement intended to make a future clear possible. A recognizable shape is not enough: the queue, entry path and post-clear board must also work.

Continuation →
What you build after the current setup or opener. Read the remaining board and queue rather than assuming a memorized continuation is always available.
T-slot →
A cavity intended for a T piece. A T fitting inside does not automatically earn a spin: the entry, final action and occupied corners must satisfy the game's detection rules.
