How Book of Aztec Works
Book of Aztec is a 5-reel, 3-row video slot with 10 adjustable paylines from Amatic. The game transports you to ancient Mesoamerica, where you search for lost treasures alongside a fearless explorer.
Wins pay left to right on adjacent reels across active paylines. The Book symbol is unique: it acts as a Wild substituting for all symbols, and as a Scatter paying on any position. Three or more Books anywhere trigger the Bonusspin feature.
During the 10 bonusspins, one symbol is randomly chosen to become the expanding symbol. When this symbol appears, it expands to cover all positions on its reel. Crucially, it pays on all active lines regardless of whether the symbols are adjacent—allowing for spectacular wins across non-consecutive reels.
Symbol Paytable
Book (Wild/Scatter)
5× = 2000
Card symbols (A, K, Q, J, 10) offer lower but more frequent payouts, ranging from 100 to 150 coins for five of a kind. All paytable values are multiples of your line bet, except scatter wins which multiply your total bet.
Bonusspin Feature Explained
The Bonusspin round is where Book of Aztec reveals its true potential. Here's exactly how it works:
- Land 3, 4, or 5 Book symbols anywhere in the base game to win 10 bonusspins instantly
- Before the bonus begins, the game randomly selects an expanding symbol from any symbol except the Book
- During each bonusspin, regular wins are paid first according to standard payline rules
- Then, if the special expanding symbol appears, it expands to fill its entire reel
- The expanded symbol pays on all active lines, even if symbols aren't consecutive—meaning you can win on reels 1, 3, and 5 without needing reels 2 and 4
- During expansion, the Book does not substitute for other symbols
- The bonus can retrigger: 3+ Books during bonusspins add another 10 spins to your remaining total
The expanding symbol mechanic is what makes this feature powerful. If the Explorer Woman is selected and appears on three reels, you're paid for three of a kind across every active line simultaneously.
