How to play Book of 99
Book of 99 features a classic 5-reel, 3-row layout with 10 fixed paylines. The betting range is flexible, starting at $0.10 per spin and going up to $100, making it suitable for both budget players and high rollers.
The symbols are beautifully designed to match the Egyptian theme. Lower-paying symbols include classic card icons (10, J, Q, K, A), while higher-paying symbols feature thematic icons like scarabs, pharaohs, and the Book of 99 itself. The Book symbol acts as both the Wild and Scatter, substituting for other symbols and triggering the Free Spins Feature.
Wins are to be had by landing three or more matching symbols on an active payline, starting from the leftmost reel. The game’s straightforward mechanics and intuitive interface make it easy for players of all skill levels to jump in and start spinning.
Bonus features and special symbols
Free spins feature
The Free Spins Feature is the highlight of Book of 99. It’s triggered by landing three or more Book symbols anywhere on the reels. You’ll receive 10 free spins, and before the bonus spins start, a random symbol is chosen to become the expanding symbol.
During the free spins, if you land three or more of the chosen symbol, it expands to cover the whole reel, significantly boosting your chances of big wins. What’s more, the Free Spins Feature can be retriggered by landing three or more Book symbols during the round, offering you even more opportunities to win.
Wilds and special symbols
The Book symbol in Book of 99 serves a dual purpose. It acts as the Wild, substituting for all other symbols to help form winning combinations, and as the Scatter, activating the Free Spins Feature. This makes it one of the most important symbols in the game.
Mobile experience and accessibility
Book of 99 is well optimised for mobile play, guaranteeing a seamless experience across Android and iOS devices. The game’s crisp graphics and smooth animations translate perfectly to smaller screens, while the intuitive touch controls make it easy to modify your bets and spin the reels.
Whether you’re playing on a smartphone or tablet, Book of 99 delivers the same high-quality experience as its desktop version. This makes it a great choice for players who enjoy gaming on the go.
