The Archaeology of Big Wins: How Book of Secrets Works
Book of Secrets™ isn't your typical Egyptian-themed pokie—SYNOT Games has crafted a 5-reel, 3-row slot with 10 fixed paylines that delivers both classic gameplay and innovative bonus mechanics that Aussie players have come to expect from premium pokies.
Base Game Mechanics
The game operates on a straightforward left-to-right win system across 10 always-active paylines. Bets range from a modest $0.10 minimum up to $80 maximum per spin, making it accessible for casual punters and high rollers alike. All payouts multiply your total bet amount, not per-line stakes.
The Book of Secrets symbol is the star of the show. As the Wild, it substitutes for every other symbol to help create winning combinations. But it's also a Scatter, paying 2x, 20x, or 200x your total bet when you land 3, 4, or 5 anywhere on the screen—no payline required.
Free Spins with Expanding Symbols
Here's where Book of Secrets truly differentiates itself. When 3 or more Book symbols appear anywhere, you trigger 10 free spins. Before the free spins start, the game randomly selects one regular symbol to become the Special Symbol.
During free spins, after regular payline wins are calculated, if enough Special Symbols land for a payout, they expand to fill entire reels. The expanded symbols then pay like scatter wins—they don't need to be on adjacent reels or start from the leftmost position. This means you could have Special Symbols on reels 1, 3, and 5, and still score a 3-of-a-kind win.
If you're lucky enough to land 3+ Books during the free spins round, you retrigger another 10 free games with the same Special Symbol. This is where the maximum win potential of $110,000 comes into play.
Symbol Payouts That Matter
The Explorer Woman wearing her iconic fedora hat tops the paytable at 500x for five-of-a-kind. The golden Pharaoh Mask follows at 200x, while the emerald Scarab Beetle and jeweled Ankh Cross both pay 75x for a full line.
Lower-paying symbols are the classic card ranks—A, K, Q, J, and 10—stylised with Egyptian flair and paying between 10x and 15x for five matches. Even landing just two Explorer symbols pays 1x your bet, giving you frequent small wins to keep your balance ticking over.
RTP and Volatility
With a theoretical return to player of 96.05%, Book of Secrets sits comfortably in the fair range for Australian online pokies. The game leans toward medium-to-high volatility, meaning you'll experience dry spells punctuated by significant wins—especially when you land a high-value special symbol during free spins.
Why Australian Players Rate This Pokie
Aussie punters appreciate pokies that balance entertainment with genuine win potential. Book of Secrets delivers familiar Ancient Egypt theming with a fresh twist on the expanding symbol mechanic. The free spins feature triggers regularly enough to keep gameplay exciting, and the gamble feature adds an extra layer of decision-making for those who enjoy risk-reward scenarios.
The game's mobile optimisation means you can spin the reels during your commute or lunch break without compromising on graphics quality or gameplay smoothness. SYNOT Games' HTML5 build ensures compatibility across all modern devices without downloads or app installations.
