Highlight Features

Symbol Upgrade

Symbol Upgrade is a powerful feature that progressively converts low-value symbols on the reels into higher-value ones as the game proceeds. The core of this feature is not just a one-time symbol change, but a 'growth' structure where lower-tier symbols are permanently removed from the reels and replaced by higher-tier ones. This drastically increases the average expected payout of the reels towards the end of the round.

Retrigger

A Retrigger means winning additional free spins by landing scatter symbols again during a free spins bonus round. Furthermore, some slots adopt an 'unlimited retrigger' system, which means there is no limit to the number of times it can re-trigger. In theory, if luck is on your side, the free spins can continue indefinitely, making it one of the most powerful features a slot can have.

Bonus Buy Efficiency

Price x80

Low Bonus Buy Price

This slot's bonus buy price is below the usual range for comparable slots. That makes buying the feature relatively accessible, especially if you want to try the free-spin round directly. Keep in mind that some games offer multiple free-spin tiers, and SlotWise uses the lowest available buy price as the reference. A lower price may also mean that the free-spin feature itself carries a lighter payout profile than higher-priced games.
