Best 'Book of' Slots Online: Top Games You Can Play in 2024

• Books have provided authors and readers with access to incredible adventures that are only limited by their imagination.

• It's easy to see why they've featured in so many slot themes, and in this guide, we've looked at the best 'Book of' online slots.

• Just like all the other slots in our extensive catalogue, these games feature plenty of bonus rounds, rounds of free spins, and popular slot mechanics.

1. Book of Dead

The Book of Dead slot is based on an ancient Egyptian collection of spells designed to protect the dead in the afterlife. Play'n Go uses this game to introduce the world to Rich Wilde, a fearless archaeologist on a mission to unearth lost treasures. The slot features several Egyptian artefacts as its symbols and includes a bonus round of free spins with a randomly-selected expanding symbol. You can also gamble any payout using an optional feature that can instantly double or quadruple your prize.

2. Book of Adventure Super Stake Edition

Deep underground in a poorly lit Egyptian tomb lies the Book of Adventure Super Stake Edition slot. This StakeLogic creation includes a round of free spins with a random expanding symbol. Beginning with 10 free spins, this bonus can be retriggered, each time adding a new expanding symbol. You can also activate the Super Stake feature to double your wager for a higher probability of landing winning combinations.

3. Legacy of Dead

The Book of Dead slot proved so popular that Play'n Go released a sequel called Legacy of Dead. While this game does not feature Rich Wilde, it does take you on yet another adventure deep underground. Similarly, the slot offers a bonus round with free spins which begins with a random standard symbol given expanding capabilities. If the bonus is retriggered, an additional expanding symbol is activated, and this feature can go on repeating itself until there are nine active expanding symbols.

4. Rise of Merlin

While a mage is the central protagonist in the Rise of Merlin slot, he depends on a book for spells and incantations. This visually-stunning game includes several mythical creatures, including dragons, as well as powerful magical crystal balls that can help the mage to read someone's future. Three crystal balls trigger a round of free spins where a standard symbol is selected to expand. This bonus can be retriggered, and every time that this happens, an additional expanding symbol is chosen.

5. Cat Wilde and the Pyramids of Dead

Play'n Go's Rich Wilde has a daughter, Cat, who also loves going on adventures looking for lost treasures. The Cat Wilde and the Pyramids of Dead slot is similar, at first, to the Book of Dead slot that inspired it, however, everything can change when a bonus feature is triggered. Three scatters landing on the grid can lead to either an instant cash prize of up to 500x, a round of eight free spins, or a jackpot bonus with a 5,000x top prize.

6. Book of the Irish

The Book of the Irish slot is an unusual combination of 'Book of' and Irish themes. Developed by Inspired, this slot's main feature is its bonus round which begins with 10 free spins. Before this bonus begins, a random standard symbol is selected to be the bonus' expanding symbol. The slot also offers an optional gamble feature that gives you the chance to double your prize or win free spins instantly.

7. Book of Kings

The Book of Kings slot is one of Playtech's entries in the 'Book of' slot genre. Based in the Egyptian desert alongside the tombs of kings, this slot shares many similarities with other games in this list. Three scatter symbols trigger a bonus round with an expanding symbol, however, if the Book and Snake symbol helps to trigger this bonus, a 3x multiplier is also applied.

8. Pilgrim of Dead

The success of the Book of Dead is evident in the sheer number of sequels. Pilgrim of Dead is one such example, and while there are many similarities between the two, there are also stark differences. When a bonus round is triggered and a symbol is selected to expand, players have the option to reject it. This will select another random symbol which players cannot reject. In addition, the first expanding symbol to land on the grid stays sticky for the duration of the round.

9. Book of Golden Sands

Pragmatic Play has not stayed out of the 'Book of' slot theme. Book of Golden Sands is one of its most popular releases in this category as it offers a free spins bonus where expanding symbols can be collected. As you collect these symbols, they're added up to boost future winning combinations, and this could lead to a max payout of 10,000x. This slot also offers the optional Buy Bonus option for 100x your base stake.

10. Book of El Dorado

The legendary and lost South American city of gold is the main theme of Pragmatic Play's Book of El Dorado slot. In this game, three scatter symbols trigger a round of 10 free spins where two standard symbols are chosen randomly and given the power to expand. The bonus round can be retriggered an unlimited number of times, however, the expanding symbols remain the same.
