Number of features contributing to each role. One feature can contribute to several roles.
Each bar counts the features that contribute to a functional role. One feature can contribute to more than one role. Bar lengths are scaled to the largest count within this game; compare the numbers when looking across games.
These counts describe feature composition. They are not win probabilities, payout contributions, or quality ratings.
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.
Auxiliary Prize/Multiplier Reel is a unique and innovative feature that introduces a dedicated vertical reel operating independently of the main game grid. This additional reel does not participate in forming standard payline wins, but instead serves a specialized function: it exclusively lands on either win multipliers or fixed jackpot prizes. The core of this feature is to provide an instant, dynamic enhancement to any wins achieved on the main reels, adding an extra layer of excitement and potential to every spin.
High Bonus Buy Price
This slot's bonus buy price is above the usual range for comparable slots, so buying the feature is not the default recommendation. It may still be worth considering if the free-spin round offers unusually strong mechanics, higher volatility, or a payout profile that is meaningfully richer than standard features. Without that extra upside, the buy price may feel expensive relative to typical bonus buys.
