Break the Vault MultiBoost Slot Overview
Break the Vault MultiBoost is a new casino slot from Jelly that takes us straight into the middle of a high-octane bank heist. The reels are packed with guns, gold bars, and safes bursting with cash, all wrapped in a style that makes you think of a more violent version of Netflix’s Money Heist or classic Hollywood robberies like Heat, released in 1995. It was a highly anticipated movie featuring both Al Pacino and Robert De Niro. The game captures the excitement of blasting open vaults while trying to escape with the loot, and it comes with some thrilling features to match. With its stacked wilds, multipliers, and a free spins mode where things can really escalate, this slot is built to deliver the tension of a robbery gone right.

Break the Vault MultiBoost is a video slot from Jelly with 5 reels, a grid setup of 3-4-4-4-3 rows, and 576 ways to win. The Min.bet is 0.2, while the Max.bet climbs up to 80. The slot comes with a max win of 6,731x the bet and an RTP that defaults to 96% (though versions of 94% and 90.5% exist).

The theme sticks tightly to its daring robbery setup. It’s a proper “grab the cash and run” slot with explosive energy. The features in Break the Vault MultiBoost are Super Stacked Wilds/MultiBoost, Safe Symbols, Free Spins, Feature Buy, and Gold Bet.
Break the Vault MultiBoost Slot Information
The slot’s design puts you right in the thick of a heist, with the reels standing in front of a bank. In the foreground are piles of cash and gold bars. A man in a suit stands to the left, while two other robbers hang out to the right of the reels. In the back is a fire from an explosion, and a helicopter hovers over the scene. Wins land when matching symbols appear on consecutive reels from left to right, starting on the first reel to the left. You can play Break the Vault MultiBoost on desktops, notepads, and mobile phones.
The lower-paying symbols in Break the Vault MultiBoost are 10, J, Q, K, and A, rewarding between 0.5x and 1x the bet for five-of-a-kind wins. The higher-paying symbols are guns, necklaces, suitcases of cash, and gold bars, which pay between 2x and 4x the bet for a five-of-a-kind win. The Wild Symbols are 3 Super Stacked Wilds depicted by the robbers, substituting all regular-paying symbols to help create winning combinations.
Break the Vault MultiBoost Slot Features
What is the max win in the slot Break the Vault MultiBoost?
You can win up to 6,731x the bet.
What features are available in the slot Break the Vault MultiBoost?
The features are Super Stacked Wilds/MultiBoost, Safe Symbols, Free Spins, Feature Buy, and Gold Bet.

Super Stacked Wilds/MultiBoost
Super Stacked Wilds appear on reels 2, 3, and 4, and when they shift into view, they activate the MultiBoost. Each shift increases the multiplier by 1, making every move of these wilds more valuable. In Free Spins, the multipliers don’t reset but instead persist throughout the round, leading to some potentially explosive wins.
Safe Symbols
Safe Symbols pay when 3 or more land from left to right, starting on reel 1. Super Stacked Wilds can connect with them too, boosting payouts. The prizes range from 1x up to 100x, with Mini, Minor, Major, and Mega levels sprinkled in at 20x, 50x, and 100x. If the MultiBoost multiplier is active, all these safe prizes get multiplied.
Free Spins
Free Spins trigger when 3 or more Bonus symbols appear, with 3 giving 6 spins, 4 awarding 8, and 5 unlocking 10. Only one Bonus can land on each reel. During Free Spins, every shifting Super Stacked Wild activates the MultiBoost, and the multiplier sticks for the duration of the round. This is where the slot’s real fireworks happen.
Feature Buy
For those who don’t want to wait for Free Spins, you can buy your way in for 100x your bet.

Gold Bet
For a 50% increase to your stake, you can activate the Gold Bet. This boosts your chances of triggering Free Spins but doesn’t affect payouts or prizes directly.
Break the Vault MultiBoost Slot Conclusion
When we first loaded up Break the Vault MultiBoost, we half-expected to hear a siren go off and see someone in a red jumpsuit with a Salvador Dalà mask charging across the screen. However, this game has a rawer and more explosive touch than Bulletproof Games’ recent Vault Raiders DoubleMax, which focuses a bit more on cleverness and a bit less on muscles. Jelly clearly had fun leaning into the heist theme, and it works. The vaults, the cash, the bling, and the stacked wilds all combine into a package that feels tense and exciting.
Playing through, the base game can keep you hooked thanks to those Super Stacked Wilds nudging multipliers higher, but the Free Spins round is where things get wild. The persistent multiplier mechanic means you’re constantly hoping for another wild shift to stack the odds in your favor. Add in the Safe Symbols with their prize tiers, and suddenly it feels like you’re cracking codes and cashing out jackpots.
Of course, the volatility is high, so don’t expect smooth sailing. Some spins will feel like you’re fumbling with dynamite that refuses to go off. But when the features align, the slot delivers adrenaline-filled moments that fit perfectly with its theme. Another bank job game we really appreciate is Relax Gaming’s cartoon-looking Iron Bank.
Break the Vault MultiBoost from Jelly is a stylish bank robbery adventure with slick mechanics and strong win potential.
