If a symbol matches the top of its column — both are cleared. Otherwise it stacks.
Rotate the strip to align matches. Clear 3+ in a row horizontally for chain bonus.
Drop fast for higher multiplier (×10 → ×1). Column hits 10 = GAME OVER.

BOMB
One-time rescue. Triggers automatically when columns get dangerously high (6+). Lands on a random column top and fires diagonal rays downward, destroying cells in their path.
