Marble Cascade
Place ramps and bumpers, then watch a marble chain-react through your layout for combo points.
Tap empty slots before the marble drops to place ramps, bumpers, or redirectors from a rotating inventory; marble auto-falls and ricochets, scoring per peg and comboing through narrow gates you built.
Tap an empty slot to cycle the next piece into place; watch the marble drop.
