Bonus functions and unique mechanics
- Wild symbol «Bank with a gem»: replaces all fruits, participates in payouts and carries an initial multiplier ×1. After each payout in which the bank participates, its multiplier increases by +1. The bank is transferred across the network after cascades.
- Freespins: activate when 3 or more banks appear simultaneously. Starts with 6 free spins. All banks that land on the field during the bonus become sticky and retain their current multiplier until the end of the round.
- Rainbow function: can activate at any moment of the base game. The rainbow transmits across the network and leaves on its path one or several banks with a gem, which increases the chances of triggering freespins or a large cluster.
- Cascades (Cascading Reels): after each payout, symbols disappear, and new ones fall from above, creating the possibility for a chain of payouts within a single spin.
