Game overview
In 333 Boom Banks 2, we expanded the original heist format with a layered PowerCombo mechanic that links symbols and vault actions in one spin cycle. You interact with three coloured vaults that activate different bonus paths instead of isolated features. We designed this structure so you can switch between base play and bonus pressure without changing screens.

Bank heist theme and visuals

Coloured vault symbols and clean interface elements reflect a classic bank robbery style without extra overlays. Vault activations are marked by short animations and sound effects that signal feature entry.
How 333 Boom Banks 2 PowerCombo works
In the 333 Boom Banks 2 slot, you play on 5 reels with 20 fixed paylines that pay from left to right. Coin values are adjustable, and you collect Gem Tokens during spins to fill coloured vault meters shown above the grid. When vaults reach capacity, they explode to trigger bonus features, with up to 3 bonuses running at the same time.
Symbol values and payouts
In 333 Boom Banks 2 PowerCombo, symbols are split between high-value vault icons and lower-value card ranks. Wild and Boom Boom sit at the top tier, while cash items and playing symbols cover the standard pay range.
| Symbol | Payouts |
 | 5 = 10x 4 = 2x 3 = 1x |
 | 5 = 10x 4 = 2x 3 = 1x |
 | 5 = 4x 4 = 1.2x 3 = 0.6x |
 | 5 = 3x 4 = 1x 3 = 0.6x |
 | 5 = 2x 4 = 1x 3 = 0.4x |
 | 5 = 1x 4 = 0.4x 3 = 0.2x |
 | 5 = 1x 4 = 0.4x 3 = 0.2x |
 | 5 = 1x 4 = 0.4x 3 = 0.2x |
 | 5 = 1x 4 = 0.4x 3 = 0.2x |
 | 5 = 1x 4 = 0.4x 3 = 0.2x |
 | 5 = 1x 4 = 0.4x 3 = 0.2x |
Payouts scale directly with your bet size, keeping the same multipliers across all stake levels.
PowerCombo feature
The PowerCombo feature is the main mechanic in 333 Boom Banks 2 PowerCombo. You track three coloured vaults (Green, Yellow, Red) and collect matching Gem Tokens to fill each meter during spins. When a vault reaches its limit, it bursts open and triggers its bonus, and you can fill more than one vault to run combo bonuses at the same time.
Three vault bonus types
In 333 Boom Banks 2 PowerCombo, we linked each coloured vault to its own bonus mechanic that activates once the meter is filled. At Fortune Factory Studios, we built these three paths so you can trigger one feature on its own or combine several outcomes during the same run.
Green Vault – Extra Free Spins
The Green Vault adds extra Free Spins to an active bonus round once the meter is filled. This extends the number of spins without increasing the stake. The feature increases total spin count within the same bonus session.
Yellow Vault – Multiplier Increase
The Yellow Vault applies a win multiplier during bonus play after activation. It can run alongside other vault effects and affects all eligible wins. Multiplier values increase during the active bonus sequence.
Red Vault – Jackpot Access
The Red Vault opens access to 6 fixed jackpots, from Mini to Super Grand. One jackpot is awarded per trigger, with the outcome decided instantly. The maximum jackpot aligns with the 12,500x win cap.
Six fixed jackpots
We included a structured jackpot system in 333 Boom Banks 2 PowerCombo to define clear payout tiers within the Red Vault feature. Each level is fixed and does not depend on pooled contributions.
| Jackpot tier | Payout |
| Grand Jackpot (highest tier) | 12,500x |
| Mega Jackpot | 750x |
| Major Jackpot | 17.5x |
| Maxi Jackpot | 10x |
| Minor Jackpot | 7.5x |
| Mini Jackpot | 2.5x |
Jackpot values scale with your bet size, keeping the same ratio at £0.20 and £20. The top tier aligns with the 12,500x win cap.
Free Spins bonus round
The Free Spins round starts when you land 3+ Golden Vault scatters anywhere on the reels and it awards 10 Free Spins. During these spins, PowerCombo vault triggers can still activate, and extra scatters can retrigger the round to add more spins. This bonus is where most high-value results are concentrated due to the higher spin count and stacked mechanics.
Win Booster option
The Win Booster is an optional add-on that increases the chance of triggering bonus features during standard spins. When enabled, it raises the cost per spin above the £0.20 base stake and accelerates the vault filling process. This option is often used by British players who prefer shorter sessions with faster feature access.
