The ‘Book Of’ theme in online slots might feel overused and repetitive to experts like us, but the statistics don’t lie. Tournaments, leaderboards, and popularity sections at online casinos indicate that ‘Book Of’ slots are players’ top choice.
We can see their appeal and expand on the best ‘Book Of’ slots and their features in this article.
About ‘Book Of’ Slot Games
‘Book Of’ slots began with Novomatic’s Book of Ra slot in 2006. Play’n GO’s Book of Dead 2016 slot release reignited their popularity. 100+ ‘Book Of’ slots have followed the benchmarks set by the above two releases, but only a few got picked up by players.
These games usually adopt the following features:
- 5 reels and 3 rows with 10 – 25 paylines
- Ancient Egypt theme and a ‘book’ scatter symbol
- Free spins round with a randomly selected expanding symbol that connects indifferent to its position
- Retriggers with additional free spins and expanding symbols
- Scatter that often takes the role of the wild
- Gamble feature & newer games bonus buy too
- High volatility and 5,000x max win
Most online pokies carry similar features, so ‘Book Of’ games mainly stand out for their free spins round and book scatter. Their main downside is that they look fairly similar in gameplay and theme, while rarely featuring a second special feature like Hold & Win or Jackpots.
Our selection of ‘Book Of’ slots was curated to bring similar options with slight variations to spice things up.

Here at Pokies Bet, we play all kinds of slots. And although the ‘Book Of’ slot theme has been executed hundreds of times; we want to help you find the best slots from each category.
Below, you can review our top 5 ‘Book Of’ slot picks. They have been selected after comparing them against numerous similar games and carefully considering their math model, graphics, and gameplay.
Book of Time – most original theme
Hacksaw’s original take on classic themes is evident in the Book of Time slot game. All symbols have quirky graphics, and the grid is set in a forest. The game isn’t just original in terms of graphics, though, providing two free spins bonuses.
The classic ‘Book Of’ free spins bonus is triggered with 3 – 5 scatters for up to 20 free spins and 3 randomly selected expanding symbols. Landing extra scatters provides retriggers but not over 3 expanding symbols.
Book of Time’s 2nd bonus feature is called ‘What Time Is It?’. Here, three clocks drop expanding wild multipliers randomly on the reels for a bombastic winning spree.
All special features can be purchased for a fixed price, making Book of Time an excellent pick for even high-risk takers.
Book of Dead – most popular slot
Book of Dead by Play’n GO was the first popular video slot release to dominate both land-based and online casinos. The game hit the casino floors in 2016 and remains popular today. Book of Dead’s math model has set the benchmark for all future releases with the ‘Book Of’ theme.
The book symbol is the game’s scatter and wild symbol, making its appearance exciting for several reasons. Get 3 or more on the reels to win 10 free spins with a randomly selected expanding symbol. Retriggers are possible, and each brings another expanding wild. Filling the screen with Rich Wilde symbols is how you can bag the max win in Book of Dead.
Another highlight of this game is that you can adjust the paylines and play from as low as A$0.01 per spin! Book of Dead was followed by the release of Legacy of Dead from the same company, which feels identical but provides slightly improved RTP.
Book of Shadows – highest max payout
Nolimit City is known for its adult-themed slots, and Book of Shadows is right up their alley. This ‘Book of’ slot carries the highest max win from shortlisted titles at over 30,000x the wager.
Book of Shadows is unique from all similar takes for two main reasons. Firstly, the player can pay more per spin to change the reel setting from 5×3 reels to 5×5. The free spins round plays accordingly. Also, you get a reshuffle option for a different expanding symbol when you enter the free spins round.
Elsewhere, Book of Shadows is your typical ‘Book Of’ slot game with free spins, retriggers, and a new expanding symbol with each retrigger. Like Book of Dead, the book has a dual role as scatter and wild!
Forgotten – best RTP rating
Forgotten slot by BGaming is a ‘Book Of’ slot in terms of gameplay, not by name. The game is the most recent on our list and comes with the highest RTP at 96.89%. The max win set at 7,500x isn’t bad either. Forgotten has a bonus buy feature, scatters, wilds, x2 chance, and free spins with expanding symbols.
To enter the Forgotten slot bonus round, you need at least three book scatters. You can also buy your way into the round and choose how many expanding symbols you would like to include for a higher shot at big prizes. Up to 8 expanding symbols are offered for 535x. No other ‘Book Of’ slot provides such an option, and most of us will never experience more than a couple of expanding symbols on classic games like Book of Ra.
Book of Ra Deluxe – the most classic take
Novomatic’s Book of Ra slot established this theme and has since given birth to numerous spin-offs. Aussies can even find a Book of Ra Deluxe app to play the game for free on mobile.
The Book of Ra Deluxe version is hugely popular at online casinos despite its classic, and slightly dated, look. In terms of gameplay, Book of Ra Deluxe is the worst of all other options we’ve covered mainly because you don’t get additional expanding symbols through retriggers. However, the base symbols pay way higher values compared to the rest of the games, so landing a big win isn’t exclusively possible during the free spins.
It also feels like it is easier to get into the Book of Ra Deluxe free spins bonus round, it took me less than 30 spins on average. If you would like to see how the ‘Book Of’ slots craze began, this deluxe version is an easy-on-the-eyes trip down memory lane.

Tips to Select ‘Book Of’ Slots
The criteria employed during our assessment of any good slot game remain unchanged when searching for good ‘Book Of’ slots to play. Things like high RTP, volatility matching your bankroll, design, music, and bonus features.
My bonus tips are that players searching for classic versions of ‘Book Of’ slots should turn to Novomatic and Play’n GO, while those searching for original features should instead play releases by BGaming and Nolimit City. Hacksaw is also among the few developers to produce ‘Book Of’ slots with more than just a single free spin round with expanding symbols.

Although all online casinos feature games like the Book of Dead, you won’t find 50+ ‘Book Of’ slots at any random site. During our reviews, we’ve noticed that some operators offer a ‘collections’ lobby, grouping different slot genres based on their theme.
Our casino shortlist was curated to only include safe and reputable Aussie online casinos with a ‘Book Of’ slots collection for easy access to all highlighted games and more.
Conclusion
Why change something that works? This seems to be the mantra of casino developers still releasing ‘Book Of’ slot machines for online casino distribution. If players engage with them, it makes sense to continue bringing original themes and features no matter how many ‘Book Of’ slots are already there.
As a player, you should carefully assess your options, since there are many within this category, and pick a game that matches your expectations. For example, I am sick of the same old free spins bonus with expanding symbol which is why I gravitate towards Book of Time by Hacksaw.
Likewise, my love for Egypt has almost dried up with so many Ancient Egypt ‘Book Of’ slots, and alternative games like Forgotten and Book of Shadows feel like a breath of fresh air.
Book of 99 by Relax almost made it to my shortlist too, but it doesn’t offer much more than the stunning 99% RTP.
