Book of Madness Slot Review

Book of Madness is a horror-themed high volatility online video slot developed by Gamomat (formerly Bally Wulff). It features the typical 5-reel x 3-row grid setup, which is common with most online slot machines. The game also comes with enough bonus features that leave no dull moment in its gameplay and are capable of helping players earn generous payouts. We have the Wild symbols that will substitute and create more winning combinations Scatters that will pay out winnings and trigger the Free Spins feature, and the Gamble feature that can significantly increase your winnings.

Let’s have a look at everything about the Book of Madness slot. You should also note that you can access and play Book of Madness and other free slots online here at SlotoZilla.

Gamomat Software Provider

Gamomat (formally Bally Wulff) is a Germany-based producer of high-quality slot machines and other casino games for the global market. The company was launched in 2008 and started in the land-based market. Eventually, it also branched into producing slot machines for the iGaming industry. At the moment, Gamomat has already released more than 130 online slot titles, and players can play their games in over 35 countries and 27 languages. Some of the other Gamomat slots include Crystal Burst, Books and Temples, Back to the Fruits RoAR, Shogun’s Secret, Duck Hunter, and many others.

Pros and Cons

Here are the pros and cons of the Book of Madness slots:

  • Wilds and Scatter features are available
  • There are two types of Gamble games
  • Interesting theme and design
  • Players can earn Free Games


  • No progressive jackpot

Overall Opinion about Book of Madness

The Book of Madness online slot might not be the most impressive when it comes to overall potential, but it has a lot going for it as well. The horror theme is simply fascinating and beautifully depicted in the graphics, design, symbols, and soundtrack. It also has impressive features with good winning potential, and payouts are pretty generous.

One of the things that impressed me about this game is its Gamble Feature. Unlike other slots where you have a double or nothing type of game, it is not so here. Instead of going all-in with your winnings on any of the two different gamble games, you can get half your winnings as many times as possible. That way, if you lose the Gamble feature, you can still collect a part of your winnings.

Overall, this game is an excellent option for any slot enthusiast. The gameplay is seamless, and there has been no complaint about its performance. Also, it works perfectly well on both desktop and mobile devices.

Book of Madness Theme and Unique Features

When you play Book of Madness, you will find a horror theme that revolves around a spooky asylum where all sorts of creepy experiments are being conducted. The Book of Madness symbols, including a zombie nurse, a scary werewolf, a hospital bed drenched in blood, a blood bag, and a big syringe with a weird liquid in it, perfectly fits the theme. The same goes for the design, graphics, and soundtrack.

Like when you play the Book of Fortune slot game online, you will also come across 10 paylines on the playing grid. However, though the paylines here are adjustable, a player can only choose to play with 5 lines or the entire 10 lines.

Book of Madness Bonus Features

Book of Madness slot comes with certain features that add to the overall playing experience, and these features include:

  • Scatter – The book symbol itself is the Scatter, and its primary function is to trigger the Free Spins feature in this game. In addition to this, Scatters can also pay out some decent winnings when they land on the reels.
  • Free Spins Feature – Landing three or more Scatters will trigger the Free Spins round and award players with 10 Free Spins. At the start of the free games, any symbol except the book will become a bonus symbol throughout the bonus. Furthermore, players can trigger more Free Spins during this feature.
  • Wilds – The Book of madness itself is the Wild symbol as well. It can substitute for all symbols to create winning combinations during the regular gameplay. However, although it can substitute for other symbols during the Free Spins feature, it cannot replace the selected bonus symbols.
  • Gamble Games – Like many Gamomat slots, this game also features a Gamble Game. After any win in this game, a Gamble Feature will come up, allowing players to try and increase their winnings. Book of Madness has two different Gamble games, namely, Card Game and Ladder Game. In the Card Game, you will have to guess the color of a downward-facing card. If you are right, your winnings double, and you can go again, but if you are wrong, you lose your stake. The Ladder Game features a ladder filled with prizes, from the lowest to the highest. If you win, you will keep going higher till you get to the highest prize, and if you lose, you lose your stake.

Book of Madness Payouts

The most enjoyable part of a slot machine would be when players manage to land winning combinations and walk away with decent winnings. The Book of Madness online slot machine is one such machine that is capable of dishing out some impressive payouts. Thankfully, the betting range of the game is flexible and accommodates all players. Bet per line ranges from 0.01 credits to 10 credits, and with the 5/10 selectable paylines options, the minimum bet per spin is 0.05 credits while the maximum is 100 credits.

Although many symbols are capable of some incredible winnings, the one with the best payout is the Zombie Nurse. She can award 5000x bet per line for 5-of-a-kind symbols across an active payline.

RTP and Volatility

Gamomat set the return to player (RTP) percentage of the Book of Madness slot machine at 96.15%, which is relatively standard for the industry. This value means that the game will pay back 96.15 credits in winnings for every 100 credits wagered on it in the long run.

When you play Book of Madness online, you will also find that the game features high volatility, which brings about infrequent wins. However, whenever the game triggers winning combinations, they tend to come big due to this high volatility.

Mobile Experience

Mobile optimization has always been a trend of Gamomat slots, so it is not surprising that this game is also a mobile slot.
