How to Play
Even though Book of Muertos has pretty straightforward gameplay, we still prepared a how-to-play guide:
- Visit the casino and find the game in the library
- Start the game and load all its resources
- Set the bet size by pressing "+" and "-" in the "Per Line" section. The overall stake in the game varies between €0.1 and €100
- Read the rules and check the payouts
- Adjust the setting if you want to
- Start rolling the reels manually or by enabling auto-play
A 6x3 gaming board with 10 fixed paylines is what players can expect from Book of Muertos. The slot pays adjacently from left to right. All winning combinations start on the far-left cell and include matching symbols on 3+ reels.
The main feature of the slot's gameplay is free spins.
Book of Muertos RTP and Volatility
Book of Muertos is a highly volatile slot with an RTP of 96.01%.
Like many other "Book Of" games, Book of Muertos has high volatility. Look at the symbols' payout to see a significant difference between high-pays and low-pays. And don't forget about free spins, another volatile part of the gameplay.
The theoretical return to the player of Book of Muertos is 96.01%, which is an average value.
Theme
Muertos from Spanish means "Dead". So, we can consider the Book of Muertos a Mexican version of the Book of Dead. The slot is obviously dedicated to the Day of the Dead – a Mexican version of Halloween. Look at all those scary masks and skulls on the board.
You can also hear traditional Mexican music. The slot looks and sounds authentic and gives everyone a chance to get to know the culture of Central America closely.
You will see 10 different symbols on the board of the Book of Muertos.
The first group of symbols is cards. They are the cheapest category with the lowest odds:
- 10, J, Q: 0.5x, 2.5x, 10x, 20x
- K, A: 0.5x, 4x, 15x, 30x
The next group is high-pay regulars:
- Sombrero, revolvers: 0.5x, 3x, 10x, 75x, 150x
- Skull, girl in mask: 1x, 10x, 100x, 500x, 1,000
The main symbol is a Book. It acts as both Wild and Scatter and pays with the following odds – 2x, 25x, 250x, 500x. Three and more landed books activate free spins.
Mobile Compatibility
You can enjoy the atmosphere of the Day of the Dead on your phone or tablet. Book of Muertos is compatible with Android and iOS devices, as it was developed on HTML5 and JavaScipt.
The slot's mobile version is lightweight and functional at the same time. You can easily navigate and control the gaming process by tapping and scrolling on your gadget's screen.

Max Win
The maximum win of the game is 10,000x the bet.
Book of Muertos is not unique when it comes to the max win. Like many other "Book of" slots, it has a maximum multiplier of 10,000x. To get such a win, you must fill the entire board with skulls or girls in masks. Of course, your chances of getting the max win and big wins, generally, are higher during free spins.
Overall Rating
Book of Muertos offers a combination of a unique theme and traditional gameplay. We don't know many slots about the Days of Dead, but we know hundreds of "Book of" slots. We think that kind of combination can attract different groups of players.

A good-old “Book of” mechanics is never bad from my point of view. Free spins are a bit modified, as random expanding symbol is chosen for every spin but not at the start of the round.
The slot is volatile and can on durable down streak. Well, it’s not news for me, many Book of games act like that. And don’t forget that we are talking about Spinomenal game. The provider is not known for balanced math models.
