Discover hidden riches from antiquity as symbols expand across 10 thrilling bonus spins. The gleaming Book works double duty—acting as both wild and scatter to unlock incredible winning opportunities.
This 5-reel, 3-row Aztec adventure from Amatic combines classic slot mechanics with a powerful bonus feature that can turn any symbol into an expanding win multiplier. BF Games takes a different approach with a RESPIN mechanic that expands rows, where the grid grows from 3 to 6 rows and reaches up to 32,768 ways to win.
The golden Book symbol substitutes for all symbols and pays on any position. Land 3, 4, or 5 Books anywhere to trigger 10 bonus spins with scatter payouts of 20x, 200x, or 2000x your total bet.
At the start of bonus spins, one symbol is randomly selected to expand. This symbol pays across all active lines even when symbols aren't consecutive, dramatically increasing win potential.
Adjust your stake from CAD $1 to $500 and play between 1 and 10 paylines. The max bet button instantly sets you at the highest stake for maximum win potential on every spin.
During bonus spins, landing 3 or more Book symbols awards an additional 10 spins added to your remaining count. Keep retriggering for extended bonus rounds with the same expanding symbol.

The Book of Aztec bonus feature is where the real treasure hunting happens. Here's exactly how the expanding symbol mechanic works to boost your wins.
Land 3, 4, or 5 Book symbols anywhere on the reels during the base game. You'll immediately win 10 bonus spins plus a scatter payout based on the number of Books that triggered the feature. Relax Gaming's Book of 99 also awards 10 free spins when scatter Books land, but requires collecting 99 wild symbols to activate the feature.
Before your bonus spins kick off, the game randomly picks one symbol to expand—any symbol except the Book itself. You might land the premium Explorer, a shimmering golden artifact, or even one of the card symbols.
Regular line wins are paid first. Then, if your expanding symbol appears, it stretches to fill entire reels and pays on all active lines regardless of position. Three scattered expanding symbols can create massive multi-line wins.
During bonus spins, 3+ Book symbols add 10 more spins to your remaining total. The expanding symbol stays the same, letting you accumulate wins with the same high-value expander throughout the entire bonus session.
Book of Aztec features 10 adjustable paylines running left to right across the reels. Each payline is colour-coded on the game screen for easy tracking of your winning combinations. Endorphina's Book of Santa uses the same 10-line configuration with left-to-right payouts and a golden Book scatter that triggers the free games round.

This Amatic slot combines straightforward gameplay with genuine win potential. The expanding symbol bonus feature offers something different from standard free spins, and the dual role of the Book symbol creates frequent action. GAMOMAT's Book of Crazy Chicken Egyptian adventure delivers 10 free games with a rooster explorer as the premium symbol and identical expanding bonus mechanics.
