• Base →

  The supporting shape under a planned T placement. A complete spin setup also needs the correct surrounding corners, an accessible entry and usually an overhang.

• Overhang →

  Blocks extending above empty space. An overhang can enable a spin or tuck, but also blocks a straight drop. Always check how the required piece will actually enter.

• T-spin →

  A T-piece placement recognized as a spin by the ruleset. Common modern detection requires a final rotation and three occupied diagonal corners around the pivot. Simply dropping T into a T-shaped gap is insufficient.
