Gravity Bonanza is a space-themed online slot from Pragmatic Play that takes place on an alien world filled with planetoids. The game is played on a 7×7 grid using a cluster pays system, where wins are awarded for clusters of 5 or more matching symbols connected horizontally or vertically.
The symbols in Gravity Bonanza include various cosmic objects like planets, meteors, stars, and food items stylized as celestial bodies. The highest paying symbol is a crescent moon, awarding 1,000x the bet for a cluster of 31 or more. There are no wild symbols, but the game features a special Black Hole symbol and scatter symbols.
The key features of Gravity Bonanza revolve around the Black Hole symbol and the Gravity Bonus. When a Black Hole symbol lands, it randomly selects a pay symbol type. All instances of the chosen symbol that appear on the reels during the current spin and any subsequent tumbles are collected by the Black Hole. At the end of the tumble sequence, the total number of collected symbols is paid out according to the paytable as the Gravity Bonus prize.
Landing 3, 4, 5, 6, or 7 scatter symbols awards 10, 15, 20, 30, or 50 free spins respectively. During free spins, the Black Hole symbol can appear with multipliers of x2, x3, x5, or x10, which are applied to the Gravity Bonus prize.
Gravity Bonanza also offers a bonus buy option, allowing players to purchase entry into the free spins round for 100x their bet. The RTP when using the bonus buy is slightly lower at 95.99%.
With a highly volatile math model, Gravity Bonanza has a maximum win potential of 10,000x the bet. The game has customizable RTP ranges, with the highest being 96.09%.
