Break the Vault MultiBoost Slot

Break the Vault MultiBoost is an online slot released by newcomer developer Jelly in 2025, which has implemented a robbers theme in its gameplay. This title marks the second release in the series, returning familiar elements and introducing nuanced features to differentiate the gameplay. Unlike many classic slot games, the Break the Vault MultiBoost title features a range of advanced mechanics, ranging from the interesting payline counts and bonus games.

Break the Vault MultiBoost Game Background

The Break the Vault MultiBoost slot features a unique playgrid with a 3x4x4x4x3 layout, which differs from traditional online slots in the industry. There is a fixed payline count of 576 in this slot game, which all begin from the leftmost reel, and operate adjacent.

As we know, the Break the Vault MultiBoost slot is based on robbery and banks, which have directly influenced the slot's overall visual design. Like many slots in the genre, the gameplay will take place outside of a bank, with a range of other elements present that showcase the theme. Besides the Break the Vault MultiBoost playgrid, a car is on fire, and three robbers are visible, dressed in appropriate attire. To further reinforce the game's theme, Jelly have scattered cash notes and golden bars across the bottom of the playgrid

There is a range of slot games available here at BoyleSports Games that feature a similar visual style, including Catch the Robbers and Iron Bank.

Break the Vault MultiBoost Slot Symbols

There is a wide range of symbols in the Break the Vault MultiBoost slot, some of which complement the game's overall design. As with many online slots, the lower-value symbols are drawn from Blackjack games and feature classic playing card imagery in metallic fonts. The higher-value symbols in the Break the Vault MultiBoost slot are represented by thematic imagery, such as weapons, jewellery, and other fitting elements.

Lower Value Symbols:

Medium Value Symbols:

Gun
Necklace

Higher Value Symbols:

Briefcase of Cash
Gold

In addition to the symbols mentioned, others may land on the reels and trigger one of the Break the Vault MultiBoost bonus features. These symbols are the Bonus, Wilds, and Safe symbols, each with unique imagery that maintains the robbery theme.

Break the Vault MultiBoost Bonus Features

In the Break the Vault MultiBoost slot, Wild symbols may land on the reels and substitute for any base game symbol to create or add to a matching combination. These Wild symbols appear as full-stack symbols and, when partially in view, nudge to become fully visible. Each time the Wild symbol nudges to become a full stack, the MultiBoost Multiplier increases by +1. The MultiBoost Multiplier may be awarded if the Wild symbol is part of a matching combination, which will multiply its base game prize by the active multiplier value.

Safe symbols can land on the reels in the Break the Vault MultiBoost slot game, and if 3 or more are connected adjacently starting from the leftmost reel, a prize may be triggered. The Stacked Wild symbol can step in as a Safe symbol to connect two symbols in adjacent reels when available. Safe symbols offer a range of prizes, from multipliers of between 1x and 10x the bet stake to jackpot slots titles such as Mini, Minor, Mega, and Major, each with unique multipliers visible above the reels.

The Break the Vault MultiBoost slot game also has a Free Spins feature, which can be triggered if players land 3 or more Bonus symbols on the reels in the same spin. The number of Bonus symbols that appear will determine the amount of free spins awarded, with 3, 4, and 5 symbols granting 6, 8, and 10 spins, respectively. During this Free Spins bonus, if the Wild symbol activates the MultiBoost feature, the multiplier will remain persistent throughout the bonus rounds. Once the free spins count has diminished, players will return to Break the Vault MultiBoost base gameplay, and the multiplier will be reset.
