Overview
Spinstack is a single-player strategic stacking and clearing game. Pieces enter from above the board, and you rotate the concentric square base to decide which edge they fall toward. Complete a full square ring from the fourth layer outward to clear it. Floating pieces then collapse toward the center, creating opportunities for powerful chain reactions.
Design
Build outward around an indestructible core and carefully manage the growing board. Layers 0–3 form the permanent core and can never be cleared. Layer 4 and beyond can be completed and removed.
The game features the standard seven tetrominoes: I, O, T, S, Z, L, and J. Choose the base direction during the decision phase, adjust the piece while it falls, and rotate the piece or base depending on the selected mode.
