Playβn GO decided to pay tribute in this slot to writer H. P. Lovecraft and his insane tales of ancient beings from other dimensions. The main character is Richard Wilde (yes, the same adventurer you know from Book of Dead), this time searching for the Tome of Madness. And thereβs no doubt it really is madness β once you spin the game, youβll find this atmosphere isnβt for the faint-hearted. Tome of Madness is played on a 5Γ5 grid, where you win if you manage to connect a cluster of 4 or more symbols.
Every slot machine must be developed by a company that invented, designed and put it into operation. Many players eventually find that they only enjoy playing on machines from specific software provider, so they narrow down their selection by preferred brand.
The graphics are absolutely top-notch and perfectly match the fantasy theme. The symbols are packed with occult markings, ancient masks and dark icons. The game board sits in a gloomy room, with Richard Wilde himself staring back at you. The music is slow and ominous, layered with mysterious sounds. Every now and then youβll catch a whisper or chilling tones that wonβt let you forget youβre toying with something dangerous. The real fun starts with the bonus features and symbols, because Tome of Madness is full of crazy bonuses. Every winning combination charges the portal. Once itβs filled, various special effects trigger β like removing symbols, adding WILD symbols, or transforming icons. The WILD symbols come in plenty of forms β classic WILDs, special WILDs with multipliers, and even a Mega WILD. These WILDs also appear more often when you manage to get the portal going. When you fully charge the portal, the Other World Free Round triggers β a bonus round where loads of WILDs and special effects are added. And if youβre really lucky, you can summon Cthulhu himself, which is the absolute peak of the game. At that moment the reels go completely wild and you can land some huge wins. The volatility is high, which means the game can be pretty dry at times, but when it hits, itβs worth it. RTP sits around 96.59%, which is slightly above average. The maximum win is up to 2,000x your stake β at first glance itβs not as massive as some other Playβn GO slots, but thanks to the high volatility and mad bonuses, itβs genuinely within reach. Whatβs more, the game isnβt just about the wins β itβs an experience.

WILD symbol
The online slot Tome of Madness wouldnβt live up to its name if it only featured simple gameplay mechanics. Thatβs why youβll find three types of WILD symbols here. As always, they can substitute for other symbols whenever it suits them, because thatβs often the only way they can secure you a win. But at the same time, each of them has its own role. The Special WILD symbol can come to your aid during the portal feature. The Multiplier WILD, on the other hand, doubles all wins. And finally, the MEGA WILD is here to move around the grid after it lands, creating even more rewarding opportunities.
Cascading wins
Symbols drop onto the grid and form winning combinations. Youβll win when you hit at least 4 matching symbols connected in a single cluster. The winning symbols are then removed, and new symbols appear to fill the empty spaces. The whole sequence continues for as long as new wins keep forming.
EYE Marks
This feature triggers in completely random positions. The eye opens as soon as you create a winning combination on an eye mark position. However, if you donβt land any further wins, 2 Special WILD symbols will be added to the reels. During subsequent bonus rounds, every eye will open and youβll receive a MEGA WILD.
Portal
Every win always charges the portal meter. Once you land 7 winning symbols, 2 Special WILD symbols are added to the grid. The same happens again after 14 symbols. If you then land a win with their help, the ABYSS portal feature triggers, which removes an entire reel. At 27 winning symbols, 2 Special WILD symbols are added to the grid again, but this time the VOID portal feature triggers. If a WILD is part of a winning combination, the portal moves 1 random symbol. Removed symbols continue to contribute towards charging the portal!
Other World Free Round
You trigger this feature when you collect 42 winning symbols. This awards you 1 free round with three random portal effects. If the portal is charged, an additional portal effect is added for every 3 more winning symbols, up to a maximum of 7. During the feature, a portal effect will also trigger if there are no further wins. The portal effects include:
Special WILD symbol: 4 of these WILD symbols are added to the grid.
ABYSS: 4 Special WILD symbols are added to the grid. If you land a win with any Special symbol, the ABYSS portal effect triggers.
VOID: 4 Special WILD symbols are added to the grid. If you land a win with them, the VOID portal effect triggers.
During the feature, youβll have 11β12 EYE Marks available. If you open them all, a Cthulhu MEGA WILD symbol is added to the grid, which moves down with each cascade until it disappears.

Our rating of the game
Tome of Madness
The online slot Tome of Madness isnβt just about clicking and waiting for a win β itβs an experience. If youβre into Lovecraft, dark mythology and mysticism, this game will pull you in. The bonus features are original, suspenseful, and bring something fresh to the world of online slots. On the other hand, if youβre only after a simple, quick slot, the mechanics might catch you off guard. But if youβre not afraid to dive into the madness and summon Cthulhu onto the reels, Tome of Madness offers one of the most interesting rides among online slots.
The original Lovecraft- and Cthulhu-inspired theme is truly unique
The graphics and music create a dark atmosphere that draws you in from the very first second
The 5x5 grid and cluster system are a refreshing change from classic reels
Portal effects and different types of WILD symbols add dynamism and constant action
The presence of Richard Wilde links the game to other famous Playβn GO slots
Other World Free Round is thrilling, and the option to summon Cthulhu is genuinely epic
The 96.59% RTP is solid and player-friendly
Cons
High volatility means wins may take a while to land, so itβs not for the impatient
The maximum win of 2000x isnβt that high compared to other modern slots
The cluster mechanics may be confusing for traditional players
The dark horror theme wonβt suit everyone β if you prefer lighter slots, this wonβt be for you
On mobile it can feel a bit visually busy, mainly due to the detailed symbols and effects
Creating clusters instead of paylines wonβt be everyoneβs cup of tea
