The mystical Book of Secrets acts as both Wild and Scatter. Land 3 or more anywhere to trigger the Free Spins feature while earning scatter pays up to 200x total bet.

Receive 10 Free Spins when the sacred book appears. Before the spins begin, one symbol is chosen to become the Special expanding symbol, covering entire reels when enough symbols for a win are present.

Explorer Woman Jackpot

The adventurous archaeologist stands as the highest-paying regular symbol. Five across any active payline delivers a magnificent 500x bet multiplier, with payouts starting from just two matching symbols.

Expedition Briefing

Before your 10 Free Spins commence, Book of Secrets™ randomly selects one symbol (excluding the Wild Book) to act as the Special Symbol. When enough of these symbols appear for a winning combination, they expand to cover all three positions on their respective reels. These expanded symbols then pay like scatter symbols—meaning they do not need to be adjacent or start from the leftmost reel. This creates opportunities for massive wins across non-traditional patterns.

Absolutely. Landing 3 or more Book symbols during your Free Spins awards an additional 10 spins with the same Special Symbol that was selected at the start. The Free Spins feature can be retriggered multiple times, and all spins are played at the same bet level as the round that originally triggered the feature.

SYNOT Games has designed Book of Secrets™ to accommodate various bankroll sizes. The minimum bet is 0.10 EUR (ten cents), making it accessible for cautious explorers. High rollers can wager up to 80.00 EUR per spin. The MAX BET button automatically adjusts your stake to the maximum allowable based on your current balance. All symbol payouts shown in the paytable are multipliers of your total bet.

After any win not exceeding 55,000 EUR, you may opt to gamble your winnings via a card colour guessing game. Correctly predict red or black to double your win; an incorrect guess forfeits the entire amount. You can use the HALVE option to credit half your win to your balance while gambling only the remainder. The Gamble feature is not available during Free Spins, and you are limited to 10 consecutive gamble attempts per win. Note that Joker cards substitute for any colour.

Book of Secrets™ caps the maximum win at 110,000 EUR in a single game round. This limit is enforced before considering the Gamble feature. With the Explorer Woman symbol paying 500x your bet for five of a kind, and the Special Symbol expansion mechanic during Free Spins potentially covering multiple reels, substantial wins can accumulate quickly—especially when retriggering additional Free Spins.
