The game plays across 5 reels, 3 rows, and 10 paylines. Mystery symbols can transform into matching icons, while money symbols worth up to 5,000x trigger a respins bonus. Free spins are also available, including special Super Spins where the chosen symbol is the money orb.

The paytable reveals all symbol values and bonus features. Low card icons pay up to 7.5x, while John Hunter himself awards 100x for five-of-a-kind. Wins form across 10 paylines from left to right.
This adventure can be enjoyed on desktop, iOS, Android, and Windows mobiles without any change to the graphics, features, or controls.
Mystery Symbols: Cover entire reels and transform into a randomly chosen icon. These can pay on any reel, not just from left to right.
Money Respin Feature: Landing 6+ money orbs triggers 3 respins. Each new orb resets the counter, and the round continues until no new symbols land or the grid fills. If all 15 spaces fill, you win an extra 2,000x, though the 5,000x max win cap applies.
Free Spins: Triggered by 3+ book scatters. A random symbol is chosen as the mystery reveal for the round. Levels include:
Super Free Spins: If the Super Book triggers, the money orb is always chosen, boosting chances of activating respins during free spins.
Progression: Scatter symbols fill a meter and every fourth scatter upgrades the round and adds two more free spins. Players can gamble for higher levels before the round begins, though losing removes the free games.
The game features a maximum win of 5,000x your stake, which can reach 1,250,000.00. It is rated highly volatile, meaning wins are less frequent but typically larger when they land. The RTP is an above-average 96.50%.
