Rules & Rotation

Rotation SystemSRS uses modern five-test kicks. ARS uses TGM-style spawn states, two-state I/S/Z pieces, right-biased horizontal kicks, and no I kicks. Piece Randomizer7-Bag guarantees all seven pieces per bag. History-4 emulates the less predictable TGM distribution. Enable HoldShow the reserve slot and allow one swap per active piece. Next QueueNumber of upcoming pieces rendered. The internal queue remains five pieces deep. Ghost PieceShow the landing projection beneath the active tetromino. 180° RotationAdd a one-button half-turn using conservative SRS+/ARS kick tests. Initial RotationApply a held rotation input as the next piece enters the well. Hard Drop BehaviorLOCK places immediately. SONIC moves to the floor but preserves lock delay.

Handling & Timing

DASDelay before a held horizontal input begins auto-shifting. ARRInterval between auto-shifts. 0 ms moves instantly to the wall. Soft Drop FactorMultiplier applied while Down is held. Instant acts as a non-locking sonic drop. Lock DelayGrace period after a piece touches the stack. Lock Reset LimitMaximum grounded movement/rotation resets per piece.
