The game is built on a 5-reel, 10-payline structure and offers high volatility, ensuring that every spin is filled with excitement and potential for big wins.

The theme of Book of 99 is steeped in Greek mythology, transporting players to a world of ancient gods, heroic figures, and mythical creatures.

The symbols on the reels further enhance this theme, showcasing characters such as the cyclops, the fearsome Lamia, and both male and female protagonists styled as ancient heroes.

Book of 99 operates on a standard 5×3 reel grid with 10 fixed paylines. The game’s RTP stands at an exceptional 99%, a rarity in the world of online slots. This high RTP means that players can expect a better return on their bets over time compared to many other slot games.
The game features both low-paying and high-paying symbols:
Winning combinations are formed by landing matching symbols on adjacent reels, starting from the leftmost reel. High-paying symbols offer substantial rewards, with a full line of five symbols paying between 75 to 500 times the stake.
Players can place bets ranging from a minimum of 10 cents to a maximum of 100 dollars per spin, accommodating both casual players and high rollers.

The bonus game in Book of 99 is a key highlight, offering players a chance to trigger free spins and significantly boost their winnings.
The bonus game can be activated in two ways:
Before the free spins begin, one of the regular pay symbols is randomly selected to become a special expanding symbol. During the free spins, if this special symbol lands, it expands to cover the entire reel after any regular wins are paid out. These expanded symbols pay out from any position on the reels, not just adjacent ones, increasing the chances of substantial wins.
Additionally, landing three or more book symbols during the free spins will retrigger the feature, providing even more opportunities to accumulate big wins.After any win, players have the option to enter a gamble round, where they can attempt to double or quadruple their winnings by guessing the color or suit of a face-down card.
Book of 99 stands out in the crowded ‘book of’ slot market with its exceptional RTP and engaging features. The game offers a visually appealing journey through ancient Greece, complemented by a thrilling bonus game that includes expanding symbols and a unique wild collection system. With high volatility and the potential for substantial payouts, Book of 99 is a compelling choice for both novice and experienced slot players.
