With its very high volatility and an RTP of 95.1%, Book of Time Machine is designed for players who enjoy tense, anticipation-filled gameplay where a single spin can transport you to a massive payout. At Slottomat, you can try this temporal adventure for free, experiencing all its features without risk. This comprehensive review will break down everything you need to know about the mechanics, symbols, and special features that make this slot a standout title.

Game Overview & Theme

Book of Time Machine transports you across different historical epochs, from the age of dinosaurs to ancient Egypt and beyond. The visual presentation is crisp and engaging, with a steampunk-inspired time machine interface framing the reels. The soundtrack builds suspense, perfectly complementing the high-stakes nature of the gameplay. Unlike traditional comic book slots, this game leans into historical adventure, using the "Book" mechanic as a gateway to different eras. The 5x3 grid and 20 fixed paylines provide a familiar layout, but the real magic begins when the special Book symbols start to work.

Symbols, Paytable & Betting Range

Before you set the dials on your time machine, you'll need to place your bet. Book of Time Machine accommodates a wide range of players with a betting span from a minimum of €0.10 up to a maximum of €100 per spin. The symbols are a mix of thematic icons and classic card royals. The lower-paying symbols are the 10, J, Q, K, and A, styled to fit the adventurous theme. The higher-value symbols are thematic artifacts you might collect on your journeys: a mysterious urn, an ancient dagger, a golden scarab, and a majestic eagle. The most valuable standard symbol is the Explorer character. However, the key to unlocking the game's true potential lies with the special symbols: the Book of Time Machine itself acts as both the Wild and the Scatter.

The Book of Time Machine: Wild & Scatter Feature

The titular Book of Time Machine is the engine of this game. This golden, glowing book serves a dual critical function. First, it acts as a Wild symbol, substituting for any regular pay symbol to help form winning combinations on the 20 paylines. Second, and more importantly, it is the game's Scatter. Landing three or more Book symbols anywhere on the reels triggers the main event: the Free Spins feature. This is the core of the experience and where the biggest wins are waiting to be discovered.

Free Spins & The Special Expanding Symbol

Triggering the Free Spins round with three or more Book Scatters is your ticket to the past. You are awarded 10 free spins to start. Before the round begins, the game randomly selects one regular pay symbol to become the "Special Expanding Symbol" for the duration of the free spins. This mechanic is central to all "Book of" style games. When this special symbol lands in sufficient numbers (at least 3) on a payline during the free spins, it expands to cover the entire reel, dramatically increasing the potential for huge wins. If you manage to land three or more Book Scatters again during the free spins, you will retrigger an additional 10 free spins, extending your journey through time.

Gamble Feature (Optional)

For players seeking an extra adrenaline rush, Book of Time Machine includes a classic Gamble feature. After any standard win, you have the option to gamble your winnings for a chance to double them. This typically involves a simple card guess (red or black) or suit guess game. It's important to remember that this is a high-risk choice; a wrong guess will result in the loss of the gambled winnings. This feature is entirely optional and can be skipped to bank your wins immediately.

RTP, Volatility & Winning Potential

Understanding the mathematical model of a slot is crucial for setting expectations. Book of Time Machine has a Return to Player (RTP) rate of 95.1%. This figure, which you can learn more about in our detailed Slots RTP Explained guide, is slightly below the current market average, indicating the game has a built-in house edge. More defining is its very high volatility. This means wins won't land frequently, but when they do, they have the potential to be significantly larger than your initial bet. This model creates a gameplay experience full of suspense, perfect for players who enjoy the thrill of the chase for a substantial payout. It's a style similar to other high-volatility adventures like The Book of Patagonia.

Tips for Playing Book of Time Machine

While slots are games of chance, a strategic approach can enhance your session. First, always play the free demo to understand the feature triggers and pace. Given the very high volatility, ensure your bankroll can withstand potential dry spells while waiting for the lucrative free spins round. The free spins feature is where the major wins are found, so patience is key. Use the game's autoplay function with caution, setting loss and single win limits to manage your session effectively. Remember, the goal of the demo is to enjoy the gameplay and thematic experience.
