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 Price Comparison

Average Bonus Buy Price

This slot's bonus buy price sits within the usual range for comparable slots. Buying the feature can be a reasonable option if your goal is to reach the free-spin round without waiting for a natural trigger. The trade-off is that you skip the base-game spins that would normally happen before the feature, including any wins or volatility from that part of play.
