Introduction to Book of Monsters
The "Book of Monsters" is an online video slot machine developed by EGT (Euro Games Technology), a Bulgarian-based software provider, in collaboration with other companies like Gamomat and various third-party developers. The game was released sometime between 2010-2020 for desktop and mobile devices. As the name suggests, Book of Monsters features creatures from mythology, ancient folklore, and popular culture, giving players an eerie yet exciting experience.
Theme, Setting, and Visual Design
The setting is a mysterious library or bookshop, with shelves stacked high with old tomes and leather-bound books containing forbidden link knowledge. A faint blue glow emanates from the walls as the game’s soundtrack plays an ominous tune reminiscent of an ancient incantation. Symbols include various mythical creatures like werewolves, vampires, mummies, skeletons, bats, spiders, wolves, and other Halloween-like creatures.
Symbols, Animations, and Sound Design
The game features 10 regular pay symbols: five high-ranking monsters (with values ranging from 0.5x to 50x the total bet), four low-paying icons representing card suits, and one special symbol called Wild Monster. Each creature has a unique animation when part of a win combination or triggered by specific bonus rounds.
Reels, Paylines, or Grid Mechanics
Book of Monsters uses a standard 5-reel setup with ten fixed paylines, each covering different combinations on the grid. There are no wild reels in this game; however, two special symbols have unique functions (explained below). The player can select from five bet levels and change their stake using buttons located at the bottom right corner of the screen.
Core Gameplay Mechanics and Flow
To begin playing Book of Monsters, players must first set their bets per line by adjusting the BET button. Wins are awarded in cash prizes based on matching combinations occurring left to right or right to left along each payline. The game has a standard auto-play function for continuous uninterrupted spins without user intervention.
Wild Symbols, Scatter Symbols, and Special Icons
There are two special symbols: Wild Monster (comprising two eyes) which substitutes all regular paying icons except the Scatter Symbol; it appears on reels 1-5 during regular gameplay but becomes active only after triggering Free Spins. The other is a standard Scatter Icon representing an ancient tome titled ‘Book of Monsters’, located exclusively on reel 4.
Bonus Features and Bonus Rounds
The game has one main bonus round triggered by the Book of Monsters icon (Scatter) appearing anywhere in view, regardless of line position or win combination requirement; this initiates Free Spins. Each appearance of three scatter icons awards two free games that reset every time a monster appears at least partially on screen during these spins.
Free Spins Mechanics and Variations
In the main bonus round (Free Spins), players are awarded 2-5 random free games per each appearing Scatter icon within one game session; the range is from 3 to 25, depending upon initial triggers or wins occurring. Every time a monster appears during Free Games at least partially on screen and covers part of paylines – their value (initial bet value) will be multiplied by an additional multiplier starting with 1x.
RTP, Volatility, and Risk Profile
Book of Monsters has an average RTP percentage ranging around 96.11-96.41%, indicating relatively medium to high volatility depending on different stake levels selected for players due to potential winnings being either moderate or very large in size (possible range from 5–2500x maximum). It may appear to have a low risk profile during small bet settings, however the max win cap can make it riskier when betting larger amounts.
Betting Range, Stake Options, and Max Win Potential
The available stakes for Book of Monsters span between $1/line (minimum) up to 10 currency units per spin; using all lines gives a total stake amount of minimum 5–50. It’s recommended not exceeding these values due to higher variance while the top wins are much lower than other games with similar bet maximums.
Game Balance and Payout Behavior
Book of Monsters is considered well-balanced by many, allowing an excellent blend between low RTP levels and high-frequency payoffs through its wild symbol acting as a substitute that may activate during each bonus round where potential combinations occur frequently enough for players to expect wins several times in succession throughout normal play sessions.
Mobile Play and Technical Performance
Book of Monsters features the same settings and game mechanics across various platforms including mobile devices supporting iOS 6/7/8+, Android operating systems (version 4+), Blackberry, Windows Phone etc., offering users flexibility without significant differences between versions available on different operating systems.
