Book of Tombs is a five-reel, three-row slot from Booming Games with 10 fixed paylines and an ancient Egyptian adventure theme. Its special Book symbol acts as both Wild and Scatter, helping complete winning combinations while also unlocking the Free Spins feature. Landing three to five Books awards eight Free Spins, during which a randomly selected symbol becomes an Expanding Symbol and covers an entire reel whenever it appears. Additional Book symbols can retrigger another eight spins and introduce further Expanding Symbols, with up to nine different symbols potentially becoming active. An optional Gamble feature also lets players risk a winning payout for the chance to double or quadruple it. With a 95.42% RTP, high volatility and a maximum win of 5,504x the stake, Book of Tombs offers a familiar but entertaining take on the Egyptian Book-slot formula.
Prepare to explore the hidden chambers of an ancient Egyptian tomb with Book of Tombs, a mythology-inspired online slot filled with mysterious artefacts, golden treasures and the promise of impressive wins. Released in January 2021, this five-reel adventure brings together a familiar Egyptian theme and the popular Book-style bonus mechanic, featuring Wild symbols, expanding symbols and retriggerable Free Spins.
The game features a 5-reel, 3-row layout with 10 fixed paylines, keeping the gameplay straightforward while offering plenty of opportunities to uncover winning combinations. Its most important symbol is the Book of Tombs itself, which acts as both a Wild and Scatter. It can substitute for regular symbols during the base game and unlock the Free Spins feature when three or more Books land together.
The real excitement begins during Free Spins, when a randomly selected symbol becomes an Expanding Symbol, covering an entire reel whenever it appears. Better still, landing additional Book symbols can retrigger the bonus and introduce more Expanding Symbols, with up to nine different symbols potentially becoming active. With a published RTP of 95.42%, high volatility and a maximum win of 5,504x the stake, Book of Tombs offers an enticing adventure for players who enjoy classic Egyptian slots with expanding-symbol features.
Before entering the ancient tomb, here are the essential details of this Booming Games release:
Book of Tombs uses a traditional five-reel, three-row layout with 10 fixed paylines. Players aim to land matching symbols along the paylines, while the Book symbol provides both Wild substitution and access to the main bonus feature.
The golden Book symbol is the game’s most important special symbol because it performs two functions.
As a Wild, it substitutes for regular paying symbols to help complete winning combinations. It cannot substitute for the Expanding Symbol selected during Free Spins.
As a Scatter, it unlocks the bonus round when three or more Books appear on the reels in a single spin. This dual-purpose mechanic makes the Book valuable during both the base game and the bonus feature.
Landing three or more Book symbols anywhere on the reels activates the Free Spins feature and awards eight spins.
The bonus round begins with one randomly selected regular symbol becoming the Expanding Symbol. Whenever this symbol appears, it expands to cover every position on its reel, potentially creating several matching combinations across the grid.
The exciting part is that the feature can retrigger. Landing another three or more Book symbols during Free Spins awards an additional eight spins and introduces another randomly selected Expanding Symbol. This process can continue, with up to nine different symbols becoming expanding during the feature.
There is no fixed maximum number of retriggers specified in the reviewed game information, which is why the feature is often described as offering Unlimited Free Spins.
The Expanding Symbol mechanic is the main attraction during the bonus round. A randomly selected symbol is chosen at the beginning of Free Spins, and whenever it lands on a reel, it expands vertically to cover all three positions.
This can create multiple matching symbols from a single reel, potentially helping to form winning combinations across several paylines.
Each successful retrigger introduces another expanding symbol, increasing the number of symbols that can transform during the bonus. With up to nine expanding symbols available, the feature can become considerably more interesting as the round progresses.
Book of Tombs also includes an optional Gamble feature that allows players to risk a winning payout for the chance to increase its value.
Players can choose between two options:
However, there is a catch. An incorrect guess means the original winning amount is forfeited. The Gamble feature is entirely optional, and players can choose to collect their winnings rather than risk them.

The Book acts as a Wild, helping complete winning combinations, and can also trigger the Free Spins feature.

During the bonus, a randomly selected symbol expands to fill an entire reel whenever it appears.

Return to Player (RTP): Book of Tombs has a commonly published RTP of 95.42%. AskGamblers rounds this figure to 95.4%, while other listings also identify 95.42% as the standard configuration. Some operators may offer alternative RTP settings, so check the game information displayed in your chosen casino.
RTP represents a theoretical long-term return across a very large number of spins. It does not mean an individual player will receive R95.42 for every R100 wagered, and it cannot predict the outcome of a particular session.
Volatility: Book of Tombs is classified as a high-volatility slot. This means results can fluctuate considerably, and players may experience extended losing periods between larger payouts. High volatility does not mean that a substantial win is due after a series of unsuccessful spins.
Hit Frequency: The published hit frequency is 34.17%. This is a theoretical statistical measure of how often the game produces a hit under its calculation rules. It should not be interpreted as a guarantee of a winning spin every few attempts.
Maximum Win: The published maximum win is 5,504x the stake. This is the game’s theoretical upper payout, not a typical result or a guaranteed outcome. The Expanding Symbols feature and retriggerable Free Spins offer opportunities for larger combinations, but reaching the maximum win remains unlikely.
Book of Tombs combines a familiar Egyptian adventure theme with a bonus feature that can become increasingly powerful as more expanding symbols are unlocked.
Explorers, pharaohs, ancient artefacts and tombs create an appealing treasure-hunting atmosphere.
The Book acts as both Wild and Scatter, making it important throughout the game.
The bonus can award another eight spins whenever three or more Books land.
Up to nine different symbols can become expanding during an extended bonus round.
Selected symbols expand to fill all three positions on a reel, potentially creating multiple winning combinations.
Players can choose between collecting a win or risking it for a chance to double or quadruple the payout.
The 5,504x maximum potential gives the game an ambitious theoretical payout ceiling.
Decide how much you can comfortably spend and stop when you reach that limit.
Remember that it serves as both Wild and Scatter, helping complete wins and trigger the bonus.
Learn how the randomly selected symbol expands and how additional retriggers introduce more expanding symbols.
Although Free Spins can retrigger repeatedly, there is no guarantee that the feature will produce a substantial payout.
The Double or Quadruple option can increase a win, but an incorrect guess forfeits the original payout. Collecting your win is the less risky choice.
The 5,504x payout is a theoretical upper limit, not a result to expect during an ordinary session.
Confirm the percentage displayed by your chosen operator before wagering real money.
Previous losing spins do not make a future win more likely. Increasing your stake to recover losses can put your budget at greater risk.
Set time limits and treat slot play as entertainment rather than a way to make money.
