How to play Gravity Bonanza mobile slot

Fall in love with this 7×7 grid where black holes can create huge scatter collect wins as this Gravity Bonanza slot takes you on a culinary journey through the known universe.

The Gravity Bonanza mobile slot is a tumbling win high variance cluster pay grid game, with a top win of 10,000x your bet and an RTP of up to 96.09%. You’ll find free spins, a special black hole collect symbols, and up to 10x multipliers, all in a sci-fi food theme.

Is this slot theme a little odd? Sure. You are floating in space, an astronaut over what looks like real moons and planets, but also chocolate chip cookie and ice cream satellites.

The main symbols are just as confused, with a real Moon as the high-paying symbol, followed by a cheeseburger Saturn, a star, a sushi roll, a green… marble? (maybe?)… and finally, a rocky red Saturn again. Because we won’t know it’s a planet if there’s no ring around it.

You soon accept it as you spin and get wins when five or more symbols touch horizontally or vertically, exploding beautifully and leaving behind space for more symbols and more wins. It’s always a satisfying grid slot mechanics.

The black hole in the Gravity Bonanza slot

The main feature in this Gravity Bonanza online slot is the special Black Hole symbol. It can show up on any reel and, when it does, will remain sticky for every tumble.

What it does is simple enough – it collects one type of symbol on that spin and every tumble, then pays out the total amount collected. Essentially, it turns one symbol into a scatter on that turn.

In the base game, this symbol helps balance out the high volatility of this game, allowing for some quick wins to fill the coffers, but it’s in the free spins where you’ll get most of your big wins.

Free Spins with up to 10x multipliers

You’ll stick around for the black holes but fall in love with the free spins as three or more little alien spaceships trigger the Gravity Bonanza slot bonus.

Nothing changes, except this time, the Black Hole can randomly come with a 2x to 10x multiplier on all the scatter wins. It is a small enough addition, but one that could see you win 10,000x your bet.

You can buy the bonus for 100x your bet, but the RTP actually lowers to 95%. It’s not something you want to see when you are spending that much cash on a hail-mary bet.

We would recommend you stick with the original slot, and if the free spins are elusive, maybe try the Krakens Sky Bounty slot instead.

Bonus Features

Cluster Pays and Tumbling Reels: 5 or more symbols touching will trigger a win. The winning symbols will explode, and more will come tumbling down, giving you another chance to get further wins. This continues until no more wins can be found.

Black Hole Symbol and Gravity Bonus: Every once in a while, you get a black hole symbol showing up on any reels. It acts as a scatter pay collector.

It chooses one symbol and collects all instances of it on that spin and further tumbles. At the end of the tumble, the gravity bonus pays an amount equal to the pay of the collected symbols - i.e. eight collected symbols pay as an 8 of a kind.

Scatters and Free Spins: 3, 4, 5, 6 or 7 Scatter Flying Saucer symbols trigger 10, 15, 20, 30, or 50 free spins. The black hole can hit a random multiplier of x2, x3, x5, or x10 during the Gravity Bonanza bonus. You can retrigger the free spins at the same amount again.

Buy Free Spins: For 100x your bet, you can buy the free spins. They can trigger anything from 10 to 50 free spins.
