Several special features sit alongside the core format, adding mechanical variety within a moderately sized feature set.

Hold and Respin, or 'Hold & Win', is one of the most popular core bonus game mechanics in modern slots. The essence of this feature, unlike traditional free spins, is to 'Hold' bonus symbols on the reels and 'Respin' the remaining empty spaces to fill up the screen. This system was popularized worldwide through 'Money Train 2's' 'Money Cart Bonus' and is the foundation for numerous developer-specific brand features like Wazdan's 'Hold the Jackpot™' and Playtech's 'Fire Blaze™'.
Morphic Multipliers (Feature Progression) is a unique meta-progression system that permanently enhances the potential of bonus symbols. This feature introduces a long-term goal for players by linking multiplier upgrades to repeated bonus triggers. Upon completing the Hold & Win bonus feature a set number of times, higher multiplier values are unlocked. These unlocked multipliers can then be applied to special bonus symbols in all subsequent Hold & Win features. This creates a persistent sense of achievement and a growing reward potential over multiple play sessions.
