Tome of Madness Review

Tome of Madness slot is a brilliant game by Play'N GO released in 2019 and featuring Cluster Pays mechanics. It comes with a magnificent story to tell and awesome features to provide.

Play’N GO — Slot Developer

Play'N GO is one of the iGaming leaders in the development of world-class casino content. The company was established in 1997 and was one of the first online gambling pioneers! Besides the Tome of Madness online slot, the provider has an impressive number of mega-hits in its library, including the all-time favorite Book of Dead!

Slot Theme And Storyline

The Tome of Madness slot is a sequel to the adventures of Rich Wilde, a character created by the developer. But the game is also a representation of an imaginary world described in the H.P. Lovecraft fictional writings. The monster here is Cthulhu, who resembles a giant sea monster that inspires horror.

As a regular slot player and enthusiast, I couldn't help but notice the original idea behind this Play'N GO masterpiece. Furthermore, the quality of graphics is stunning, and sinister voiceover will give you goosebumps. Thanks to an advanced HTML5 technology implemented in the machine, you can play Tome of Madness game on Android and iOS mobiles.

Tome of Madness Slot Rules And Gameplay

The Tome of Madness game takes place in a dark chamber with Rich Wilde standing next to the giant grid. It consists of 5 reels and 5 rows and is powered by the Cluster Pays engine. Four or more symbols of a kind touching vertically or horizontally form winning groups or clusters and pay according to the Paytable.

The Tome of Madness slot is packed with Autoplay, Quickspin, and various other technical settings. The betting range is detailed and relatively wide, providing betting options from €0.10 to €100 per spin. The Portal is located on the grid's left side, and charging it is your way to special modifiers and the bonus round!

Symbols And Paytable

Before continuing with the rest of my Tome of Madness slot review, let's check what is on the grid. The Paytable contains 4 high-valued and 4 low-valued regular symbols.

Rich Wilde is a Multiplier Wild and substitutes for all regular figures by doubling the payouts. Book and Cthulhu are Special and Mega wilds, respectively and also have replacing powers!

Symbol Value for 10+ Value for 9 Value for 8 Value for 7 Value for 6 Value for 5 Value for 4
Octopus Pendant 100x the bet 50x the bet 32x the bet 16x the bet 8x the bet 4x the bet 2x the bet

How To Play Tome of Madness Slot At An Online Casino?

Just like the other top games by the developer, the Tome of Madness slot is easy to find across the best casino sites. We checked all licensed operators and shortlisted those providing optimal gaming conditions. You can check them and choose a favorite for real money play.

  • Sign up and proceed with the KYC verification
  • Select a payment method and make a secure deposit
  • Look for Tome of Madness free spins to claim

Tome of Madness Bonuses And Special Features

The Tome of Madness slot is much more than another casino game based on a fictional story. It comes with advanced mechanics and a complex payout system. There are various key elements on the grid and several reel modifiers to trigger. Here is a summary of all bonus features:

Cascading Reels

Winning clusters pay sweet rewards but also explode and disappear. The other symbols on the grid fall down, creating cascades, and new ones come from above to fill out their positions. Therefore, you can win multiple times within a single paid spin and all features depend on that!

Eye Marks & Portal Effects

The Tome of Madness by PlayN GO is packed with several base game features. To unlock them, you need to open an Eye on the market grid positions. That happens by forming a winning cluster on such a mark, and this will add 2 Special Wilds to the mix.

These substituting symbols will appear when no new cascades are available in an attempt to continue the payout sequence. Moreover, all symbols participating in winning clusters will be collected by the Portal meter, which requires 42 characters. The charging process consists of 4 stages:

  • 7 collected symbols - 2 Special Wilds are added.
  • 14 collected symbols - 2 Special Wilds are added. Win with one of them to trigger ABYSS, which removes a row or column of symbols.
  • 27 collected symbols - 2 Special Wilds are added. Use one of them to win and activate VOID, which removes all symbols of one kind from the grid.
  • 42 collected symbols - bonus minigame is activated.

Other World Free Round

The Tome of Madness bonus minigame consists of just one round, but heavily enhanced by Portal Effects. They will be activated one after another until no more wins and effects are there. A bonus trigger with 42 collected symbols awards 3 Portal Effects and each batch of 3 collected symbols over add a Portal Effect for a maximum of 7!

Mega Wild Symbol

The bonus round grid will start with 11 or 12 Eye Marks, and you can open any of them by forming a winning cluster. If you succeed and activate all Eyes, the Mega Wild Cthulhu symbol will appear on the grid. It comes with a 2x2 size and will move one step below on the grid with every cascade for truly massive payouts!

Tome of Madness RTP, Volatility And Max Win

The Tome of Madness RTP is ranging, and the most widespread version comes with a rate of 96.59%. However, you should be careful about the other versions, as they won't be so generous. The alternative RTP rates are 94.52%, 91.59%, 87.52%, and 84.50%, and they are too low for a high-variance online slot!

The volatility levels suggest using a betting system, regardless of your experience and budget. Thus, you can keep the risk optimized and eventually survive until the bonus round activation. The Tome of Madness slot max win is 2,000x the bet, which can result in an ultimate prize of up to €200,000!

Tome of Madness Demo Version And Free Play

A free play version is available on SlotCatalog for unlimited tests of the game. You can activate the Tome of Madness demo via the link beneath the title of this review article. This is the most recommended way to get acquainted with the slot's rules, features, and dynamics.

Play The Game On Your Mobile

The Tome of Madness mobile mode is slightly different from the default in several interface elements. It works flawlessly in landscape and portrait mode, and I recommend the first one. There is no need to download additional software, and the only mandatory requirement is a fast and stable Internet connection.

Strategy & Tips For Winning

The best Tome of Madness strategy would be a Martingale-inspired system based on increasing bets on losing rounds. However, you need to determine the starting value of the wagers and the steps. In my experience as a passionate slot player, I have found that following these rules is far more efficient:

  • Sign up on verified and regulated casino platforms only
  • Use the Tome of Madness free play to get used to the details
  • Set a budget and sessions target goals and stick to them
  • Play the Tome of Madness slot machine with free spins
  • Change your wager, but don't make reckless bets after a few losses

The 200 Spins Tome of Madness Experience

As part of this review article, I conducted a detailed evaluation of the Tome of Madness slot. During that time, I managed to trigger all the features, but only once the Other World Free Spins. However, the Eye Marks award generously Special Wilds, as well as the Portal Meter. Abyss and Void are regularly triggered and always shuffle the grid nicely!

Pros And Cons Of Tome of Madness Online Slot

  • Bonus Game with multiple feature activations

Similar Slots To Try

The Tome of Madness Play'N GO is truly an amazing game, and it was no surprise that in 2021 the provider released a sequel. Alice Cooper and the Tome of Madness involved the notorious rock star with the horror script and somehow perfectly fit in it. The slot was loaded with engaging features like expanding wilds and a Reality Spins minigame.

If you are a fan of rock and rock stars, you must try Ozzy Osbourne by NetEnt. The medium volatile slot has an impressive RTP rate and offers Respin and Symbol Charge features, as well as a lavish Free Spins bonus. Last but not least, I must mention Book of Dead as one of the most successful Play'N GO slots. It offers a 5,000x jackpot and free spins with a revolutionary special expanding symbol!

Final Thoughts

It's awesome to see brilliant fictional writings come to life on the screens of online casino enthusiasts. The Tome of Madness slot is good enough to inspire its own TV series, and why not a video game? But after all, it's just a modern spinner packed with powerful mechanics and an intriguing scenario.

The game could confuse novice players at first, but once you activate the Portal Effects several times, it's quite intuitive. Of course, it would be best to start with the free Tome of Madness demo and switch to real money whenever you feel ready. We have the top-rated casino operators offering amazing bonus deals!
