Introduction
Join the intrepid Lara Jones in Book of Souls, where the basic 3x5 layout and ten paylines are just a small part of a very distinctive slot. If you’re looking for free Spearhead Studios slots, then this is definitely a good place to start.
Each symbol is carved on a block of stone that falls away when you spin so you can see the Mayan temple behind it. There are five card symbols (all with Mayan designs) and four higher paying regular symbols, all thematically appropriate. Card symbols pay for three or more matches, themed symbols for two or more. The Book of Souls has an impressive three part function - it pays in its own right, it works as a wild and it’s the scatter used for triggering free spins. Snake wilds can also appear at random to add extra to your game.
Theme, Graphics & Soundtrack
Deep in the jungle is an ancient ruin, its stones carved with mysterious symbols that cover the remains of a Mayan temple. Even the card symbols are drawn with Mayan calligraphy. The way the stones fall rather than spinning also adds to the realistic feel, like you’re in an actual ruin.
This site hasn’t completely been abandoned, however. There are still flaming torches burning at the entrance and a man with a gun sneaks through, obviously intent on stealing the titular Book of Souls. There’s also an explorer with a hat and a whip who looks like a combination of Lara Croft and Indiana Jones (strangely enough, she’s called Lara Jones) and you’re with her as she tries to find the book and keep it safe from her nemesis.
You can feel there is a much deeper story in this immersive, animated slot, a feeling just added to with a soundtrack that wouldn’t sound out of place in a movie set in the same location, complete with the occasional animal noise. You might even compare it to the popular Rich Wilde and the Book of Dead slot.

Book of Souls RTP & Volatility
This slot has a very satisfying RTP of 96.9%, which is at the higher end of your average slot. The volatility is medium, making it nicely balanced and suitable for a whole range of players.
How to Play Book of Souls
If you’ve made it into the depths of the jungle, then there are only a few steps you need to take to start playing this slot:
1. First, take a look at the row of displays under the reels. Some of them - like paylines - you can’t change, whilst Wins and Balance will change as you play. It’s Bet Amount that you’ll probably want to adjust.
2. Perhaps a little confusingly, the bet adjustor isn’t actually next to the Bet Amount display. You don’t just press the nearby arrows as you would on some slots. Instead, find the image of a pile of coins next to the spin button and click that to reveal available amounts.
3. For more instructions, you can go to the top right of the screen to find the menu button, which in turn will open options for settings, paytable and game rules. Familiarize yourself with everything here.
4. In the case of settings, you can change your spin speed, set a reminder for 30, 60 or 90 minutes to keep your session a reasonable length, mute all volume or adjust music and sound effects separately.
5. If you have a budget set, then you’re ready to play, but there is one more decision to make. Autoplay can be set for up to 100 spins, with the option to stop when you reach win or single loss limits, or when bonus spins are triggered. Alternately, you can just click spin for one turn at a time.
Bet & Win Sizes
Once you’ve found the bet adjustor you can set it to a variety of amounts between 0.10 and 100, giving you plenty of range depending on how cautious you like to be. If you get the maximum five matches on a symbol, payouts are as follows:
- 10, J, Q - 100
- K, A - 150
- Mayan Calendar, Golden Idol - 150
- Nemesis - 2,000
- Lara Jones - 5,000
- Book of Souls - 200
Book of Souls Bonus Features & Free Spins
Snake Wilds
Some people might panic when they see animated snakes starting to randomly slither across their game, but a so-called “Snake Spin” in Book of Souls is a very good thing. They will be followed by the arrival of snake wilds, between three and ten of which will take up position on the reels and potentially help you fill some winning lines.
Free Spins
Book of Souls doesn’t just offer respins, but a full free spins round. If the Book of Souls, in its function as a scatter, appears three or more times on the reels, then you’ll be awarded ten free spins, which can be retriggered. During the free spins round, one of the regular symbols becomes a bonus symbol. A bonus symbol can expand to vertically fill a reel, where it acts as a line scatter.
Our Verdict
Well, it might not be the slot to play if you’re scared of snakes, but other than that this is an exciting and well-designed offering. The graphics and theme create a truly immersive experience, particularly with the animations, both during regular spins and before Snake Spins. Laden with atmosphere and extra features, what isn’t to like about Book of Souls?
