Bonus Features: Key to Big Wins
The bonus feature system in Iron Bank is a multi-layered mechanism that significantly increases win potential. The developers have provided for both random features in the base game and three full-fledged free spins modes.

- Can lead to an instant bonus trigger
Random Mystery Symbols

Mode 3: Multiplier Collect
Parameters:
- Initial number of spins: 12.
- Volatility: High.
- Optimal for: Consistent win accumulation.
Mechanics:

Potential: Predictable win accumulation with the possibility of extending the round. Tests show stable results of x47 - x48.
