Clear full rows. Doubles, triples, quad clears and combos send interference rows to a rival. Clearing rows cancels incoming interference. The ghost shows your landing spot.

Everyone gets the same seven-piece bags. Hold once per piece. Last surviving stack wins. A solo room starts practice; matches last up to ten minutes.
