In 2025, Gamomat released the Book of Madness 2 slot machine, a logical sequel to the original Book of Madness. At the time, the original game had attracted the attention of many players and breathed new life into the game’s mechanics, which had become bogged down in its Egyptian theme. The new game retained the core mechanics and promised good chances for big wins, but its visuals were radically changed, adopting a more unsettling theme. In this review, we will try to determine whether the developer has managed to replicate its success and retain its fans, or if the original game remains unbeatable.
Before we begin, I want to point out that this is a high-volatility slot machine. This game is geared more towards experienced players who are willing to take risks to win big. However, these are just characteristics; in reality, the game can be a good choice even for beginners, and this review will explain why.
The main feature of Book of Madness 2 is its brand-new look. This horror game takes you to an abandoned hospital with creepy corridors, filled with blood and a zombie nurse. During my test, I noticed a successful combination of a terrifying atmosphere and classic slot machine mechanics. Admittedly, this design won’t appeal to everyone, but I wouldn’t call it overly scary. I recommend trying the game out for yourself and forming your own opinion.
The graphics and sound quality are excellent. The background is animated, and visual effects on the playing field enhance the game’s dynamism. A rather unsettling and monotonous background score plays, and the sounds of the playing field only heighten the tension. Total immersion in the action is guaranteed, a real strength. Even long gaming sessions won’t be boring.
I also have fond memories of the mobile version. The interface is pleasant, even on a small screen, and the graphics quality remains as high as on PC.
The Book of Madness 2 slot machine features a traditional payout mechanic. The game board consists of 5 reels, each displaying 3 symbols. Winning combinations can be collected on 5 or 10 paylines; the player can adjust this setting independently. All winning combinations begin on the leftmost reel, and the symbols must be located on adjacent reels. To win, you must land 2 to 5 identical symbols on a payline.
The payout depends on the symbol that forms the winning combination, as well as the bet, which is adjustable. Before the game starts and at the beginning of each new spin, you can choose a bet between $0.05 and $100 per spin. The bet amount also depends on the number of active paylines. You can bet a minimum of $0.01 per line, making the slot machine more appealing to beginners.
High-paying symbols, such as a zombie nurse, a mummy, a mutant mouse, and a serum, offer significant multipliers, ranging from x0.5 to x500 of the stake. They allow you to win with as few as two symbols on a payline, but their frequency is quite low.
The low-paying symbols are represented by card values. They form a winning combination as soon as three of these symbols appear on a payline. The multipliers are small, ranging from x0.5 to x15. However, they appear frequently in winning combinations. These wins form the basis of the game and keep your bankroll at its initial level. The longer you play, the greater your chances of triggering the bonus game with its maximum winning potential.
The bonuses in Book of Madness 2 will allow you to win big. I’ll explain them in more detail and recommend you read them carefully before playing for real money.
As expected, the book serves two functions simultaneously: Scatter and Wild. As a Wild, it substitutes for other symbols, allowing for more winning combinations. As a Scatter, it triggers the bonus round with maximum payout potential.
The free spins round can be triggered by a combination of 3, 4, or 5 Scatter symbols on the game surface. You will receive 10 free spins, regardless of the number of bonus symbols. Additional free spins are possible for repeated Scatter combinations.
Before the free spins round begins, 1 to 9 special symbols are selected. If these symbols appear on the game surface, they expand to cover the entire reel. This increases the number of winning combinations and generates significant payouts. Furthermore, special symbols generate wins wherever they appear on the game surface, even if they violate the rule about adjacent reels.
After each win, you decide whether to collect your winnings or try your luck at doubling them. In the mini-game, you must guess the color of the face-up card. If you guess correctly, your winnings are doubled; otherwise, you lose them. You can double your stake up to 5 times in a single round.
The game is characterized by high volatility. This means you’ll receive large wins, but they won’t come frequently. That’s why I find it difficult to recommend this slot to beginners, as it will be hard to make significant winnings with a small bankroll. However, given the wide betting range and the traditional Book of Games mechanics, I can assure you that even beginners have a chance to win big. You just need to choose the right strategy.
The return to player (RTP) rate is 96.11%, which is in line with the average and proves that long gaming sessions can be as profitable as possible.
In conclusion, I can say that the Book of Madness 2 slot machine is a successful sequel to the original. It retains the core mechanics that made the original game so popular, but its design has been completely revamped and its bonuses improved. The ability to activate up to 9 expanding symbols during the bonus round is the main reason for the significant wins, while the design and soundtrack make the game more engaging and dynamic.
