Book of 99 Slot Review
Book of 99 is a video slot developed by Relax Gaming and released in May 2021. This slot features a classic 5x3 reel layout with 10 fixed paylines, offering a straightforward yet engaging gameplay experience. Set against a backdrop inspired by ancient civilizations, specifically drawing from the narrative of Homer's Odyssey, the game presents thematic symbols and characters such as Odysseus, Pythia, Polyphemus, and Lamia. With a high volatility level and an impressive RTP of 99%, Book of 99 combines risk with the potential for substantial rewards.
Game Layout and Betting Options
The slot’s layout consists of five reels and three rows, with 10 fixed paylines where wins are counted from left to right. Players can place bets ranging from €0.10 up to €100 per spin, accommodating both cautious players and higher-stake gamblers. The game does not feature both-way paylines, so winning combinations must start from the leftmost reel and follow one of the ten active paylines.
Symbols and Theme
Book of 99’s symbols are closely tied to the theme of ancient Greek mythology and the Odyssey. Premium symbols include characters such as Apollo, Pythia, Polyphemus, and Lamia, each offering varying payout values. Apollo is the highest-paying symbol, awarding up to 500 times the bet for five on a payline. Pythia, Polyphemus, and Lamia also provide substantial payouts, with rewards scaling based on the number of matching symbols landed. Lower-paying symbols are represented by royal card icons like A, K, Q, J, and 10, which offer smaller but more frequent wins.
The Book symbol serves a dual purpose as both a wild and scatter. As a wild, it substitutes for all other pay symbols to complete or enhance winning combinations. As a scatter, it triggers the bonus features of the game.
Gameplay Mechanics and Features
Book of 99 incorporates several mechanics that enhance the gameplay experience. The Book Wild symbol is central to the game’s progression, not only substituting for other symbols but also contributing to the Book Collection meter. Each Book Wild collected adds to this meter, and once 99 books are accumulated, the bonus round is triggered automatically.
Winning combinations require at least two matching premium symbols or three matching royal symbols on a payline, starting from the leftmost reel. The hit frequency is approximately 29.83%, which means players can expect a reasonable number of wins during their sessions, although the high volatility indicates that larger wins may be less frequent but more significant when they occur.
Bonus Features and Free Spins
The highlight of Book of 99 is its free spins feature, which is activated either by collecting 99 Book Wilds or by landing three or more Book scatter symbols on the reels during a single spin. Once triggered, the bonus round awards 10 free spins.
At the start of the free spins, a special expanding symbol is randomly selected. This symbol can be either a character or a royal card. If a character symbol is chosen, the expanding feature activates when two or more of that symbol appear anywhere on the reels. For royal symbols, three or more are required to trigger the expansion. Unlike standard expanding symbols that need to be adjacent, all instances of the selected symbol expand after the win calculation, covering the entire reel and increasing the chances of bigger wins.
During the free spins, the expanding symbol mechanic significantly boosts the potential for large payouts. Additionally, the free spins can be retriggered by landing three or more Book scatter symbols again, granting extra spins under the same expanding symbol conditions.
Maximum Win and RTP
Book of 99 offers a maximum win multiplier of 12,075 times the stake, providing an opportunity for substantial payouts during the bonus rounds. The theoretical Return to Player (RTP) rate is set at 99%, which is notably high compared to many other video slots. This RTP, combined with the game’s high volatility, suggests that while wins may be less frequent, they can be quite rewarding when they occur.
Visuals and Compatibility
The game’s visual design complements its theme with a classic Greek temple grid and symbols that reflect the Odyssey story. The artistic style is clean and thematic, enhancing the overall atmosphere without overwhelming the player.
Book of 99 is fully optimized for both desktop and mobile platforms, including Android and iOS devices. It does not require any additional app downloads and can be played directly through web browsers. This accessibility ensures that players can enjoy the game on various devices without compromising the gameplay quality.
Demo Mode and Integration
For those interested in trying Book of 99 without risking real money, the game is available in a free demo mode on freedemo.games. Playing the demo allows users to familiarize themselves with the gameplay mechanics, paylines, and bonus features before committing to real bets.
Additionally, Book of 99 can be downloaded for free or integrated into other websites using a widget, plugin, or API, making it a flexible option for operators looking to add a high RTP, high volatility slot to their game portfolio.
Conclusion
Book of 99 by Relax Gaming combines a classic slot layout with a rich thematic backdrop and engaging mechanics. Its high RTP of 99% and high volatility provide a balanced mix of risk and reward, appealing to players who appreciate both frequent smaller wins and the chance for larger payouts. The Book Collection meter and free spins with expanding symbols add depth to the gameplay, while the straightforward betting range and fixed paylines make it accessible to a wide audience. Whether playing for real money or in demo mode, Book of 99 offers a solid slot experience centered around ancient Greek mythology.
