Book of Reels: A Slottomat Adventure into Ancient Tomes


Start a mysterious journey with Book of Reels, a engaging video slot from the innovative provider Slottomat. This game transports players to a world of ancient knowledge and hidden treasures, wrapped in a classic "book" theme with a modern twist. While the specific RTP for Book of Reels is not publicly listed, Slottomat has designed it with a high volatility model, promising a gameplay experience filled with suspense and the potential for significant wins during its special features. With 20 fixed paylines and a betting range accommodating both casual players and high rollers (€0.10 to €100 per spin), this slot offers a straightforward yet deeply engaging adventure. In this comprehensive review, we'll explore every page of this enigmatic game, from its core mechanics to its lucrative bonus rounds, and see how it stacks up against other popular titles.

Game Theme, Visuals, and Sound Design


Book of Reels presents a familiar but well-executed archaeological theme. The reels are set against the backdrop of an ancient, dusty library or tomb, with stone textures and mystical glowing lights. The symbols are a mix of classic card royals (10-A) styled with an ornate, aged font, and higher-paying thematic icons like a scarab beetle, an ankh, a golden eagle, and a mysterious explorer. The book itself acts as both the Wild and Scatter symbol, crucial for unlocking the game's main excitement. The soundtrack features an atmospheric, suspenseful tune with subtle sound effects for spins and wins, enhancing the exploratory feel without being overwhelming. The visual presentation is clean, modern, and focuses player attention squarely on the reels and the potential of the special book symbol.

How to Play Book of Reels: Rules & Paytable


Getting started with Book of Reels is intuitive. Players first set their total bet using the coin value and bet level controls, with the final wager reflecting the cost per spin across the 20 fixed paylines. Wins are awarded for landing three or more matching symbols on consecutive reels from the leftmost reel, with the book symbol substituting for all regular symbols. The highest paying regular symbol is the explorer, followed by the eagle, ankh, and scarab. The card suit symbols offer smaller, more frequent wins. The key to the game's potential lies in the special book symbol. Landing three or more of these anywhere on the reels triggers the Free Spins feature, which is where the high-volatility nature of the game truly comes to life. For players new to slot terminology like "volatility" or "scatter," our comprehensive Slot Features Glossary provides clear explanations.

Special Features and Bonus Rounds


The gameplay in Book of Reels revolves around its special features, designed to deliver those thrilling, high-volatility moments.



  • Book Wild & Scatter Symbol: The golden book serves a dual purpose. It acts as a Wild, helping to complete winning combinations. More importantly, it is the Scatter. Landing 3, 4, or 5 book symbols anywhere on the reels triggers 10 free spins.

  • Free Spins with Expanding Symbol: This is the core bonus round. Before the free spins begin, one regular symbol (excluding the book) is randomly chosen to become a special expanding symbol. During the free spins, if you land enough of this chosen symbol to form a win (2 or more on a line), it will expand to cover the entire reel, potentially creating massive wins across multiple paylines. This mechanic is the primary driver for the game's biggest payouts.

  • Retriggering Free Spins: The bonus round is not a one-and-done affair. Landing 3 or more book scatter symbols during the free spins will award an additional 10 free spins, providing extended play and more chances for the expanding symbol to work its magic.

Book of Reels RTP, Volatility, and Max Win


Slottomat has not publicly disclosed the exact RTP (Return to Player) percentage for Book of Reels. This is not uncommon for some providers, and it means players should focus on the confirmed mechanics. The game is officially classified as having High Volatility. This means wins may not land frequently, but when they do, especially during the free spins feature with expanding symbols, they have the potential to be substantial. The combination of a potentially high max win (exact multiplier not specified) and high volatility makes this a slot suited for players who enjoy tense, anticipation-building gameplay where a single bonus round can significantly impact their session.

How Book of Reels Compares to Other Slottomat Games


Slottomat has a diverse portfolio, and Book of Reels fits neatly within their collection of feature-driven games. It shares the "book" mechanic foundation with its sibling, Book of Reels Hold & Win, which incorporates a popular "hold and win" respin bonus for a different kind of prize collection. Compared to the classic fruit-themed Mega Fruit 20, Book of Reels offers more complex features and higher volatility. It differs from the fishing adventure of Mega Fishing Mania in its thematic setting but matches it in its potential for big feature wins. Fans of sci-fi themes might also enjoy Slottomat's Coin Galactic, while those seeking a classic Vegas vibe can try Sizzling Sevens Special.
