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

Introduction

Experienced slots fans will be familiar with the ‘Book of’ game mechanics, which are some of the most popular slots in online casinos. Book of Ra, developed by Novomatic, was the first of these games to launch, although it’s unlikely that the software developer would have been aware just how iconic this game was about to become. There are now well over 20 games that have adopted the ‘Book of’ title, as well as the general gaming mechanics.

Take a look through the available options and you’ll find that ‘Book of’ games come in a whole range of styles. The original Book of Ra obviously takes an Egyptian theme, as do many subsequent games, including the Rich Wilde and the Book of Dead free slot. But you’ll also find the same mechanic deployed across other themes too, including Book of Aztec, Book of the Ages and Book of Crazy Chicken - proving that slots developers have got a good sense of humour!

Graphics & Soundtrack

Promatic are rapidly making a name for themselves with stunning graphics, immersive soundtracks and a good understanding of exactly what slot fans enjoy in their games. Book of Mystery looks absolutely stunning, as we’ve come to expect from this developer.

Book of Mystery RTP & Volatility

This game has an RTP of 96.24%, which is slightly above the average for an online slots game. And it’s a low-volatility game, so even a modest gaming budget should be sufficient to fund a fairly lengthy gaming session.

How to Play Book of Mystery

Seasoned ‘Book of’ slots fans will want to dive straight in and start spinning those reels. But if you’re less experienced, just follow our easy steps to get started.

1. All ten paylines are fixed in place, so you only need to decide on your wager before starting your game. If you already know you’d like to play at maximum stakes, simply hit the Max Bet button to the left of Spin.

2. When you’re ready to play, hit the Spin button, which will play out one game at your chosen bet.

3. For multiple spins at the same bet level, choose the Autoplay function.

4. The menu button lets you view the game’s rules and paytable, as well as adjust game sounds to your liking.

Bet Sizes & Paytable Wins

Play from 0.01 to 10.00 per payline. This will give a wagering range from just 0.10 to 100.00 per spin, so just about every type of gamer will be able to find their sweet spot. Most symbols require you to match three or more across a payline to win a cash prize. But in this game, higher-paying symbols start paying out awards for matching just two, starting from the leftmost reel.

10 = 1x, 2x, 8x

J = 1x, 2x, 8x

Q = 1x, 2x, 8x

K = 1x, 3x, 12x

A = 1x, 3x, 12x

Anubis = 1x, 3x, 10x, 75x

Eye of Horus = 1x, 3x, 10x, 75x

Pharaoh mask = 1x, 3x, 15x, 150x

Female explorer = 1x, 10x, 100x, 500x

Book Scatter / Wild = 2x, 20x, 200x

Book of Mystery Bonus Features & Free Spins

The bonus features of Book of Mystery will be instantly familiar to all ‘Book of’ fans. They start with the book symbol itself, which is the game’s Wild and Scatter combined. So it can substitute for all other symbols, helping to form winning combinations every time it appears on the reels.

To activate the book’s Scatter function you’ll need to spin up three or more. And because it’s a Scatter they don’t have to appear on a payline, so if you can see three or more Scatters on the screen, you’ve won an instant cash prize. But you’ve also activated the Free Spins bonus round, which gives 10 Free Spins with an Expanding Symbol. The book opens and scrolls through all of the symbols, selecting one at random to become the Special Symbol. Every time this symbol lands, it can expand to fill the reel, potentially triggering some big wins in the process.

There’s also an optional Gamble game that follows every win. If you take up the challenge, you’ll be shown four pieces of parchment. Two of them are blank, but two of them are treasure maps - pick a map and you’ll double the value of your win. Select a blank parchment and you forfeit that win. You can Gamble a win up to ten times for any wins below 100.00.

Overall Review

Book of Mystery has a ready-made audience thanks to the popularity of the gaming mechanic. So if you’re already a fan of any similar games, you’re definitely going to love this offering from Promatic. We particularly liked the generous RTP and low volatility, which puts this game within reach of every type of player, no matter how modest their gaming budget.

We recommend playing the game in demo mode for a while to gauge how far your bankroll could take you if you decide to play the game for real money at an online casino. We’ve got a great selection of free Promatic slots right here on our site, as well as hundreds of games from other software developers too. So if Book of Mystery isn’t to your tastes, you’re sure to find a game that is. Search for games by software developer, by theme or by feature, such as expanding wild symbols.
