Overhang

Related terms

• Hole →

  An empty cell below occupied cells. It cannot be filled by a straight drop from above; some gaps allow a tuck or spin, while others require clearing the covering rows first.

• Tuck →

  Move a piece sideways under an overhang before locking. A spin uses rotation to enter; a slide uses horizontal movement. Both need a reachable path and enough time before lock.

• 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.
