🎰 General Information

Book of the Fallen is a video slot developed by Pragmatic Play, one of the leading providers in the iGaming industry. Released in 2021, this title immerses players in the mysterious world of ancient Egypt, where pharaohs and lost tombs conceal legendary riches. The game combines classic elements of the Book of series with modern mechanics and stunning visual design.

The game is built on a 5-reel, 3-row grid with an adjustable number of paylines ranging from 10 to 20. This flexibility allows players to tailor their risk and reward profile according to their preferences. The medium-to-high volatility ensures that while wins may not land on every spin, they are significant when they do — a feature that appeals to seasoned slot enthusiasts.

✨ Game Features

Book of the Fallen is packed with features that elevate the gameplay beyond a standard Egyptian-themed slot. Below is a breakdown of the core mechanics and special symbols.

📖 The Book Symbol — Wild & Scatter

The book acts as both a Wild and a Scatter symbol. It substitutes for all regular symbols to help form winning combinations. Additionally, landing three or more books anywhere on the reels triggers the Free Spins bonus round. This dual functionality is a hallmark of the book slot genre and keeps the gameplay dynamic.

🔄 Expanding Symbols

At the start of the Free Spins round, one regular paying symbol is randomly selected to become the Expanding Symbol. During free spins, this symbol expands to cover the entire reel when it appears, paying out on all visible positions. This mechanic can lead to massive wins, especially when the high-value Anubis or eye of Horus symbols are chosen.

🎁 Gamble Feature

After any win, players have the option to enter the Gamble feature. They can double their winnings by correctly guessing the colour or suit of a hidden card. The gamble offers two stages: first guess colour (red/black) for a 2x multiplier, then guess suit (spades/hearts/diamonds/clubs) for a 4x multiplier. A wrong guess forfeits the win. This feature adds an extra layer of excitement for risk-tolerant players.

⚙️ Paylines Adjustment

Unlike many modern slots that use fixed paylines, Book of the Fallen allows players to choose between 10 and 20 lines. Fewer lines mean lower total bet per spin but also fewer chances to win. Experienced players often use this to stretch their bankroll or focus on high-volatility play.

💎 Symbol Payouts

The paytable is divided into low-paying and high-paying symbols. The low payers are classic card ranks (10, J, Q, K, A) stylised with Egyptian motifs. The high payers include:

• Scarab Beetle — medium value
• Anubis — high value
• Eye of Horus — highest regular symbol
• Book — wild/scatter

Five of a kind of the Eye of Horus pays 500x your line bet, while five Anubis symbols pay 200x. The book symbol pays 100x your total bet for five of a kind.

🚀 How to Play

Getting started with Book of the Fallen is straightforward, even for beginners. Follow these steps to join the adventure:

1. Set your bet size — Use the +/- buttons at the bottom of the screen to adjust your coin value and bet level. The total bet is displayed clearly. Minimum bet is €0.10, maximum is €100 per spin.
2. Choose the number of paylines — Click the payline button to select between 10 and 20 lines. More lines increase your total bet but also your winning potential.
3. Spin the reels — Press the spin button (circular arrow) to start a single round. For uninterrupted gameplay, use the autoplay feature to set a predetermined number of spins (up to 100) with optional stop conditions.
4. Watch for special symbols — Keep an eye out for the book symbol. Three or more trigger the free spins round, where the expanding symbol mechanic can lead to substantial payouts.
5. Use the gamble feature wisely — After any win, you can choose to gamble. Decide if you want to risk the win for a chance to double or quadruple it. Use sound strategy: gamble small wins, keep large ones.

💡 Pro Tip: Always adjust your paylines to match your bankroll strategy. For maximum coverage, play with 20 lines. For a tighter, high-volatility session, reduce to 10 lines and increase your bet per line.

💰 Bonuses and Free Spins

The Free Spins round is the heart of Book of the Fallen. Triggered by landing three or more book scatters anywhere on the reels, players are awarded 10 free spins for 3 books, 15 for 4, and 20 for 5. The scatters do not need to be on an active payline.

⚡ Expanding Symbol Mechanic

Before the free spins begin, the game randomly selects one regular paying symbol to become the Special Expanding Symbol. This symbol can be any of the card ranks or Egyptian icons. During the bonus round, whenever this symbol appears on a reel, it expands vertically to cover the entire reel, paying out on all positions simultaneously. If multiple expanded symbols land, they are evaluated together, often resulting in full-screen wins.

🔄 Retriggering Free Spins

Free spins can be retriggered by landing three or more book scatters again during the bonus round. Each retrigger awards an additional 10, 15, or 20 spins respectively. There is no upper limit to retriggers, making it possible to accumulate dozens of extra spins and build massive winning streaks.

🎯 Bonus Buy Feature (Where Available)

In jurisdictions that permit it, Book of the Fallen offers a Bonus Buy option. For a price equal to 100x your current bet, you can instantly trigger the Free Spins round. This feature is ideal for players who want to bypass the base game and get straight to the high-potential bonus action. Note that the bonus buy may not be available in all countries due to regulatory restrictions.
