Create cluster wins whilst exploring the cosmos in Gravity Bonanza™. This intergalactic voyage is played across 7×7 reels and features various asteroids, stars, and moons as its symbols. These must form an adjacent cluster of five or more matched symbols to award a win which are then removed from play, triggering a cascade of new symbols to fall from the top of the game board. A black hole can also land on the reels gathering all instances of a random symbol and paying its cluster prize at the end of the round, this will also trigger additional tumbles as symbols are removed.
