Book of Treasures - Review, Demo Play, Payout, Free Spins & Bonuses

Introduction 

Book of Treasures by Thunderspin Gaming combines strong Mayan theming with two exciting feature rounds and a generous 243 ways to win.

 
Theme, graphics & soundtrack 

The Mayan theme is one of the most enduring in online slot games. Book of Treasures provides an immersive playing experience, with the action taking place between two huge Mayan monuments that sit behind constantly flickering flames and beneath palm trees with their large leaves in perpetual motion. 

The symbols are not enclosed in boxes or frames; instead, they float against the backdrop of a Mayan building, which further adds to the immersive feel of the game. The symbols are suitably Mayan themed and feature jewel-coloured faces, birds, and traditional Mayan iconography. This is nothing that online slots players won’t have seen before, but it is perfectly passable and well-designed.

The soundtrack complements the graphics and is calming and evocative of a Mayan temple. There is an impressive change of tempo in both the graphics and the music when the free spins round is triggered and the action moves inside the temple. 

Book of Treasures RTP and Variance 

The RTP of Book of Treasures is 96.50 per cent. It is a high volatility game, which means wins can be infrequent but can be for considerable amounts when they land. 

We recommend trying Book of Treasures and other Thunderspin free slots in demo mode here at Slots Temple to get a feel for the gameplay and payouts before committing your own money at an online casino. 

Players who enjoy high volatility slot games, such as Rich Wilde and the Book of Dead, Cleopatra, Mystery Museum, Lara Croft Temples and Tombs, and the Book of Dead slot, are likely to enjoy playing Book of Treasures.

Bet sizes & paytable wins

There are ten paying symbols including the wild, which is the highest paying symbol and substitutes for all other symbols. The wild also acts as a scatter symbol and is used to trigger the free spins feature. The top win is 1,500x the total bet.

There are a generous 243 ways to win across a standard 5x3 grid. 

The minimum stake is 0.20 and the maximum stake is 2,000. Whilst this caters to the majority of online slots players, it may not be suitable for high rollers. It is also possible to purchase the free spins round, but this comes at a high price of 80x the bet amount.

Book of Treasures bonus features

Book of Treasures has two bonus features:

Free spins 

Three or more book symbols are required to trigger the free spins feature; the more books that land, the more free spins are awarded up to a maximum of 50. During the free spins feature, one of the higher paying symbols occupies one of the three vaults and plays in the same way as the Book of Treasures bonus feature in the base game. Free spins can be retriggered; if they are, higher paying symbols will fill additional vaults. 

Book of Treasures bonus feature

This sounds more complicated than it is, which is why we recommend having a few spins in demo mode. During each spin, the bottom symbol on the middle reel emerges from a book; if this symbol features on any two reels apart from the middle reel, these reels will be filled with the symbol and multiple winning lines will be formed. Blank reels that do not contain the required symbol are disregarded for the purpose of calculating any winnings. The wild symbol can also emerge from the book, which can lead to significant wins. 

Book of Treasures review: our verdict

Book of Treasures is an action-packed game with a much-loved Mayan theme. Free spin and bonus hunters will find much to like about this game; however, due to the high variance of the game, patience is required. Although the option to purchase free spins is nice to have, the high price tag is likely to be off-putting for many players.
