The Top 10 ‘Book of’ Slot Games: Max Wins, Features and Studios

Introduction

The 'Book of' series of slot games is a popular category that appears on many top slot sites. The first game was 'Book of Ra,' released way back in 2005. This slot started life as a land casino game, which was a huge hit in Germany. It was then brought online, where it became an overnight hit around the world.

Many of the games feature an ancient book as a key symbol, and they all have similar game features, which is what they are acclaimed for. The headliner is their Free Spins feature, where a special expanding symbol is randomly chosen before the free spins begin. This symbol can cover entire reels and can lead to bigger wins. Many of the games also have a Respin feature, and some even have unlimited respins, so there are lots to shout with these superb slots.

Play’n Go has created many of the ‘Book of’ slot games, including one of the most famous titles, Book of Dead, and its follow-up, Legacy of Dead.

Right, let’s get stuck in and take a look at these iconic games.

The Top 10 'Book of' Slot Games

Here at OLBG, we have years of experience working in betting and playing slot games. Therefore, we’ve created this list of the top 10 ‘Book of’ slot games based on our many insights from the last few years. So let’s dive in and tell you all about the top 10 slot games available, as there are many out there to choose from.

1. Book of Dead by Play 'n GO

Book of Dead is one of the most popular ‘Book of’ slot games of all time and has become a cult classic. The highest RTP is slightly above average at 96.21%. But there are other RTP rates out there which range from 96.21% down to to 84.18%. The game has an ancient-Egypt theme which is fronted by the adventurer Rich Wilde. 

The Free Spins bonus feature is where the game shines, and here you’re awarded 10 free spins. When triggering the Free Spins bonus round, you receive a payout of 2, 20 or 200 x the bet depending on the amount of Scatters that land. You can trigger an extra 10 free spins during the bonus round. Like all ‘Book of’ slot games, the key feature is that before the bonus round begins, a symbol is chosen randomly, which will become a special expanding symbol. If you trigger this expanding symbol on a few reels, it can give you some huge wins. To give you an example - Rich Wilde is the highest-value symbol, and if he fills all positions on the grid, you can win the maximum jackpot available, which is 5,000 x your bet.

2. Book of Ra Deluxe by Novomatic

This is the game that has launched 1,000 games - well, not quite 1,000 - but a fair few. The Book of Ra was the original ‘Book of’ slot game that was released back in 2005 and then Novomatic brought out Book of Ra Deluxe in 2008 and it was another overnight sensation. The theme is the popular genre of ancient Egyptian. There is one bonus feature to enjoy - the Free Games feature, which offers you free spins. 

Triggering it requires landing 3 or more Book of Ra Scatters anywhere on the reels. This awards you 2, 20, or 200 times your bet (for 3, 4, or 5 scatters). You then enter the bonus round and are awarded 10 free spins. Like all ‘Book of’ slot games, just before the feature starts, an expanding symbol is selected at random. Whenever this symbol lands on the reels, it expands to cover the entire reel, provided it contributes to a winning combo. If the chosen symbol appears on all five reels, it fills every position on the screen.

3. Legacy of Dead by Play 'n GO

Legacy of Dead is another title with an above-average RTP of 96.58% and an Ancient Egypt theme to boot. It’s a follow-up to the popular Book of Dead game and it was created by Play 'n GO. Again, when landing a Scatter to enter the Free Spins bonus round, you’re awarded up to 200x your bet, depending on how many Scatters land. 

A special expanding symbol is then randomly chosen. When the symbol lands, it then takes over the whole reel, which increases your chances of winning more.  During the Free Spins round, you receive 10 free spins, and if you land 3 Wild Scatters, the Free Spins bonus feature is retriggered. Here you’ll also receive another special expanding symbol. You can retrigger the bonus round several times in fact, you can get unlimited free spins, although the extra expanding symbols have a limit of 9.

4. Book of 99 by Relax Gaming

This game is all about the 99s, and I’m not talking about ice cream. Book of 99 has an impressive 99% RTP which is unusually high in the online slots world. Again, this has an ancient theme, although this time, we’ve shifted over to Greece. Like the previous games, the Free Spins feature and random expanding symbols are the bread and butter. However, this time, there are 2 ways to trigger the Free Spins feature. 

Firstly, it’s the standard way: landing 3 or more Scatters, where you receive the usual random expanding symbol and 10 free spins. Alternatively, you can collect Wild symbols using the Collection feature. Here each time a Book Wild/Scatter symbol lands, it’s collected in a meter. Each collected Book Wild/Scatter means you progress along a treasure map. When you’ve collected 99 Book Wild/Scatter symbols, you’ll enter the Free Spins feature.

Oh, and there’s also retriggers where landing 3 or more Book Wild/Scatter symbols during the Free Spins feature means 10 extra free spins.  And there’s no limit on how many extra free spins you can receive.

5. Book of Shadows by Nolimit City

Like most slot games by the masters of macabre Nolimit City, this game is stuffed with features. This title takes a different approach in that it has a horror theme. The RTP rate ranges between 96.01% and 96.19% depending on where you play. There's an innovative feature where you choose how many rows you want to play on. You can choose between 3 and 5 rows which makes the paylines between 10 and 20, respectively. 

And like all ‘Book of’ games, you can expect an expanding symbol plus unlimited free spins during the Free Spins feature. You also have an opportunity to swap your expanding symbol, which is pretty nifty. Book of Shadows also pays more than most 'Book of' slots with 30,338 times bet max wins.

6. Book of Kingdoms by Pragmatic Play

Another adventurer graces the screen in this desert-themed slot game by Pragmatic Play. which has a 96.69% RTP rate. Like most games, you’ll receive a payout once you trigger the Free Spins bonus round, which is 1 - 20 x your bet. An expanding symbol is randomly picked, and you are then awarded 5 free spins. You can also trigger 5 more free spins by landing 3 Scatters - in fact, you can win unlimited free spins, which is superb. 

There is also a Money Respin feature which is triggered by landing 5 or more Silver Coin symbols. Any standard symbols are then removed from the grid and the triggering coins lock in place. Initially, 3 respins are awarded, and the reels are made up of blanks and coins. If you land a coin, it’s also locked in, and the respins reset to 3. The round continues until you’re out of respins or you’ve filled all of the reels with silver coins.

Look out for the Minor, Major, or Mega Jackpot amount, as each coin comes with a cash value attached. At the end of the round, the cash values are added together for your overall award.
