Of course, you’ll be joined by a deranged nurse, an angry werewolf, and a zombie on the reels. Other symbols include blood bags, injections, and a bloodied hospital bed.

The book symbol is special, as it serves as both the wild and the scatter. The graphics and eerie soundtrack combined create that perfect horror feel for more immersive spins.

Game Mechanics

Book of Madness Deluxe is a 5-reel, 3-row slot game that allows you to choose between 5 and 10 paylines. Wins are formed with 3 or more matching symbols on the reels. Wins pay from left to right.

The game is playable on all devices, with bets ranging from €0.05 to €100.00 per spin. You can also activate Turbo Spin if you prefer to speed up your gameplay. You can also activate auto spin for automated spins.

The game is a high-volatility slot with a 96.15% return-to-player percentage. This means winnings don’t drop too frequently, but when they do, they can boost your bankroll quite nicely.

You can hit a maximum payout of 5,000x your bet playing this Gamomat slot.

Special Features

The slot doesn’t have an overflow of features, but there’s a decent selection to increase reel entertainment.

Wild & Scatter Symbol:

The Book of Madness is the wild and scatter of the game. It substitutes for all symbols except stamped bonus symbols in free games.

Free Games:

Landing 3 or more scatters triggers 10 free spins. During the free spins, you can trigger additional free spins. The free games begin when a bonus symbol is drawn. Any symbol except the wild can become a bonus symbol.

Bonus Buy:

There are various bonus bet options you can use for a chance to head straight into the bonus rounds.

Bonus Hunt: Costs 3x your bet and gives you 5x better odds of hitting the free games.
Buy Free Games: Costs 100x your bet and triggers the free spins.

Gamble Feature:

There are two gamble features you can trigger: the card gamble and the ladder gamble.

Card Gamble: Guess the colour of the next card. Guess correctly to double your wins.
Ladder Gambler: Climb the ladder levels to increase your win potential. You can also lose your win if you’re wrong.

Play ‘On The Go’

Book of Madness Deluxe is a mobile-friendly game built with HTML5. It runs effortlessly on Android and iOS devices. On the smaller screen, the horror visuals become slightly more up-close-and-personal. So prepare yourself for a close-up experience with the nurse, werewolf and zombie. If you scare easily, the smaller screen might be a bit much.

Overall, the mobile experience gives you quality betting opportunities on the go. Touch controls are easy to find and use. However, accessing the Buy Feature can be tricky, so use caution.

CasinoWow Game Verdict

This slot checks all the boxes and fits right in with the Book of Madness saga. While the graphics, sounds and symbols are worth staying for, we’d be lying if we said it’s unique. It’s a continuation of the previous games, and when it comes to horror and asylums, we’d have liked to see some innovation on the reels.

However, if you enjoy a good saga, familiar features and big payout potential, then CasinoWow recommends Book of Madness Deluxe. With its 96.15% RTP, free spins, and max wins of 5,000x, it’s a fun slot nonetheless.
