• Bonus Symbols: Trigger Free Spins.
• Safe Symbols: Offer instant cash prizes ranging from 1x to 100x your bet.

Core Features Explained

MultiBoost Mechanic

The star of the show is the MultiBoost feature, activated by Super Stacked Wilds. When these wilds shift into view, they increase the multiplier by +1. During the base game, this resets after each spin, but in Free Spins, the multiplier persists, creating massive win potential.

Safe Symbols

Landing 3 or more Safe Symbols from left to right triggers instant payouts:

• Mini: 20x
• Minor: 50x
• Major: 100x

If the MultiBoost multiplier is active, these prizes are multiplied, making Safe Symbols a lucrative addition.

Free Spins

Free Spins are where the real magic happens:

• 3 Bonus Symbols: 6 Free Spins
• 4 Bonus Symbols: 8 Free Spins
• 5 Bonus Symbols: 10 Free Spins

During this round:

• Multipliers from MultiBoost do not reset.
• Every shifting wild adds to the multiplier, stacking up for explosive wins.

Feature Buy

Impatient? You can buy Free Spins for 100x your bet, giving you instant access to the game’s most rewarding feature.

Gold Bet

For an extra 50% stake, activate Gold Bet, which increases your chances of triggering Free Spins without altering payouts.

Math Model and RTP Analysis

With an RTP of 96% and high volatility, Break the Vault MultiBoost caters to risk-takers who love big swings. The hit frequency of 31.86% ensures a decent flow of wins, but the real payouts come from Free Spins and stacked multipliers. The max win of 6,731x is impressive, making this slot a serious contender for high rollers and thrill-seekers alike.

Mobile Compatibility

Optimized for desktop, tablet, and mobile, the game runs smoothly across all devices. The responsive design ensures that the cinematic visuals and dynamic animations remain intact, whether you’re playing on a big screen or on the go.
