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.

Wheel of Fortune

Wheel of Fortune is a bonus game styled after a TV show's 'prize wheel', where the player spins a large wheel divided into multiple segments to win the prize indicated by the pointer when it stops. This feature is simple yet allows for very dramatic presentations, which is why it is very frequently used as a method for determining the winner of a progressive jackpot.
