Book of Aztec from Amatic delivers a gripping adventure through ancient Mesoamerican temples with a 5-reel, 3-row layout and 10 adjustable paylines. The golden Book symbol serves dual duty as both Wild and Scatter, substituting for all symbols while also paying on any position. Landing three or more Books anywhere on the reels awards 10 bonusspins with a randomly selected expanding symbol—excluding the Book itself—that pays across all active lines regardless of position.
The theoretical RTP of 95.09% positions Book of Aztec in the medium range for player returns. Wins occur left-to-right on adjacent reels across your active paylines. Only the highest win per line is paid, but wins from different lines accumulate. Scatter wins from the Book symbol are added on top of line wins and are calculated as multiples of your total bet, not line bet.
The ancient Book acts as a Wild symbol, substituting for all other symbols to complete winning combinations on your active paylines. It appears on all five reels and can dramatically increase your hit frequency by filling gaps in near-miss patterns.
As a Scatter, the Book pays on any position regardless of paylines. Landing 3 Books = 20x, 4 Books = 200x, or 5 Books = 2000x your total bet. These wins are added directly to any line wins from the same spin.
When you trigger the bonus with three or more Book symbols, the game randomly selects one symbol—any except the Book—to become the expanding symbol for the duration of your 10 bonusspins. This chosen symbol expands to fill entire reels and pays according to the paytable across all active lines, even if the matching symbols are not consecutive. Crucially, during the expansion phase, the Book no longer substitutes, meaning only the selected symbol counts for those expanded wins. You can retrigger an additional 10 bonusspins by landing 3+ Books during the feature, adding them to your remaining spin count.
All paytable values shown are line bet multipliers for standard symbols. The Explorer Woman offers the top payout at 5000x your line bet for five-of-a-kind, while the Pyramid and Book scatter both pay 2000x for five symbols. Medium-value card symbols Ace and King share identical payouts, as do the lower-value Queen, Jack, and Ten trio.
Book of Aztec offers flexibility through its adjustable paylines and wide bet range. If you are playing with a smaller bankroll, consider starting with fewer active lines—perhaps 5 or even just the middle line—to extend your session and increase your chances of triggering the bonusspin feature. The Book scatter pays on any position, so you can still hit the bonus trigger even with minimal lines active.
For players seeking maximum win potential, activate all 10 paylines and use the MAX BET button to instantly set your wager to the highest level. This approach maximises your line wins and ensures every possible winning combination is captured. Keep in mind the RTP of 95.09% means the game retains slightly more than average over the long term, so manage your bankroll accordingly and set loss limits before you begin.
The expanding symbol mechanic during bonusspins is where the biggest wins occur. If the randomly selected symbol is a high-value picture symbol like the Explorer Woman or Pyramid, and it expands across multiple reels, you can achieve wins across all 10 paylines simultaneously. This non-adjacent payout structure is the key differentiator in Book of Aztec and what makes the bonusspin feature so lucrative compared to the base game.
