Understanding the slot specifications
Max Win
The payout ceiling in the game rules, usually a bet multiplier. It is a limit, not a typical outcome.
RTP
The theoretical return over a very large number of rounds. A game may have different RTP versions; the percentage does not predict a session.
Volatility
The spread of outcomes. High volatility generally means sharper swings; it does not by itself increase RTP.
Bonus buy
Paid access to a bonus feature without waiting for the regular trigger. Price and availability depend on the game and version.
Ante Bet
A higher cost per regular spin for a changed chance of triggering a feature. This is a separate mode, rather than a bonus-round purchase.
Respins
Additional spins that may retain some symbols or accumulated conditions. The exact behaviour follows the slot rules.

Iron Bank — game overview

Iron Bank combines mystery symbols and multiplier wilds with three different bank features.

What remains between feature turns

Iron Bank stages a Cuban heist alongside Jaguar. Before free spins, the plan selects mystery positions, expanding substitutes or multiplier collection. The bank remains the shared setting while those strategies change how the board develops after entry.

Six reels and four rows provide 4,096 ways. Mystery symbols reveal one type, while middle-reel wild stacks can carry multipliers. Several contributing stacks multiply their values together.

What each feature retains

Three or more Vault symbols offer 8 Mystery spins with persistent mystery symbols, 10 Expanding Wild spins with held expanded wilds during respins, or 12 Multiplier Collect spins that build reel multipliers. A full Mystery reel adds a spin; filling all three Collect meters adds 3.

In Mystery, the selected type on marked reels turns into sticky mystery symbols. They reveal a shared result each spin, and a filled reel adds another spin. Full-reel wilds work differently: their multipliers multiply together when they contribute to one combination. Similar-looking filled columns can therefore produce different calculations.

Collect’s larger opening allocation accompanies a different boosting process rather than a longer Mystery sequence. Holding wilds during respins and keeping mystery positions also retain different objects. The chosen strategy determines which part of an earlier turn can be reused.

Common questions

Where can I check RTP and stakes?

In the running edition’s rules. Different configurations may use different parameters.

Are the feature and casino free spins the same?

The feature is part of the game mechanic. Casino promotional free spins have their own activation and usage terms.

Can I open a demo here?

Yes. Select “Launch demo” to load the game in the player. The demo uses a virtual balance; its language and supported currency follow the site language.
