Gravity Bonanza Slot Review
Gravity Bonanza is a new online slot from leading game provider Pragmatic Play. Set in an immersive outer space environment, this highly volatile game offers players a chance to score big wins worth up to 10,000x their bet.
Gravity Bonanza incorporates a 7×7 reel format with cluster pays, requiring groups of 5 or more adjacent matching symbols for a payout. Wins can form horizontally or vertically.
The high variance slot has a default RTP of 96.09%, though this may vary between 94.00% to 96.09% based on operator. The maximum possible win is capped at 10,000x the stake.
Players can wager anywhere from $0.20 to $240 per spin across the 49 symbol positions. Gravity Bonanza includes an autoplay feature for up to 100 automated spins along with turbo mode for faster play. As a newer Pragmatic Play title, the game is optimized for mobile and desktop gameplay through instant play. No download is required.
Visual Design and Graphics
Gravity Bonanza features vivid visuals and animations that fully immerse players in an intergalactic environment. The backdrop reveals an alien planet landscape with swirling wormholes across the skies. The reels are framed by sleek space shuttle panels with an astronaut character floating nearby.
The high quality graphics and symbol animations retain their shine and smooth performance across desktop and mobile play. All symbols are thematically appropriate including colorful planets, pixel cubes, crystalline structures and space debris. Winning symbol clusters flash brightly before disappearing into black holes. Even the floating astronaut reacts with celebratory gestures.
The detailed environment, symbols and animations combine to provide an engrossing outer space setting suited to the cosmos theme. Players feel transported to the far reaches of the galaxy surrounded by the mysteries of space.
Gameplay Features and Mechanics
Gravity Bonanza incorporates Pragmatic Play’s signature tumbling reels mechanic. Any winning cluster of 5+ matching adjacent symbols awards a payout before disappearing. Remaining symbols collapse down with new ones tumbling in from above, potentially triggering chain reactions.
The unique Gravity feature activates when a black hole symbol lands on the grid. This starts capturing a randomly selected symbol type. All instances of the chosen symbol on the current spin and any following cascades get sucked into the black hole and tallied on a Gravity Meter. At the end of the sequence, the collected symbols award a payout based on the number captured.
This provides engaging anticipation as players watch to see which symbols get swallowed up, hoping to increase the Gravity Meter value for bigger payouts. Even small incremental hits feel impactful as they build the end reward.
Free Spins and Bonus Buy
Landing 3 or more Scatters during the base game awards 10 to 50 free spins, based on the number hit. Additional scatters during free games re-trigger more spins. Now the black hole can have a 2x, 3x, 5x or 10x multiplier applied to the Gravity Meter wins for tremendous payout potential.
For instant access, players can use the Bonus Buy option to purchase free spins for 100x their bet amount. This provides quick entry to the high paying bonus round. Up to 50 spins are available along with re-triggers for extended play.
Maximum Win Potential
Despite the slot’s high volatility, the dense symbol grid format leads to frequent small hits to help stabilize the risk. Maximum wins up to 10,000x the original bet are possible, especially during free games. While difficult to land, players have a shot at exponentially huge rewards through the black hole Gravity Meter payouts with multipliers in the bonus round.
Audio and Sound Effects
An ambient soundtrack builds anticipation with cosmic synths, cascading chimes and deep bass tones evoking the sensation of traversing the galaxy. Futuristic sound effects for cluster wins and black hole symbol actions enhance gameplay events. Together with the strong visuals, the audio increases immersion into this stellar setting.
Final Review Summary
Gravity Bonanza provides an engrossing outer space-themed slot experience through high quality graphics, entertaining features like the innovative Gravity Meter, and generous 10,000x maximum win potential. Cluster pays and tumbling reels keep the action moving across the 7×7 grid. Despite high volatility, small hits land frequently thanks to the large symbol layout. Overall the slot offers engaging gameplay with the potential for tremendous payouts.
