That cool Rich Wilde dude sure is kept busy in a parallel universe full of strange monsters, ghosts, and other unwanted riffraff.

Tome of Madness has elements of both Reactoonz and Moon Princess, and it just so happens that those are two of our favourite Play ‘n GO slots.

Play ‘n GO is like a fish in the water with these types of slots: lots of bonus features, surprises, boosters, and sometimes also very handsome payouts.

With Tome of Madness, you can win up to 2,000 x your total bet.

That is very nice, but it goes against the prevailing trend of all these new slots with a high variance.

How does the Tome of Madness slot work?

You play Tome of Madness on a matrix of 5 x 5 symbols. The cluster mechanism is active and winning combinations appear starting from four identical symbols.

Winning combinations disappear, after which new ones drop down in their place. That way, you can make several winning combinations in succession. It would be best if you had these to earn the extra boosters and free spins. More about this later.

First, a few house rules: the betting ranges from $€ 0.10 up to $€ 100 per spin, and the theoretical payout rate is 96.59%.

We estimate the variance to be medium.

Symbols and payouts

There are four high and four low regular symbols.

The purple amulet has the highest value: a cluster of 10+ of these symbols will get you 100 x the total bet.

If you create a cluster of Daggers, rings, or skulls, you win between 30 x and 60 x your total bet.

The four gemstones (purple, red, green, and blue) pay out a maximum of between 2 x  and 6 x your total bet.

The famous book symbol is wild and replaces all other symbols.

Portal Features: mini bonuses and extra wilds

Sometimes an eye is placed on a random spot on the matrix. If you can make a winning combination at the location of this eye, you will receive a non-winning combination of 2 random wilds as a gift.

But there is more: on the left-hand side of the screen, you see the portal filled up more as you create more winning combinations.

Two extra wilds are placed on the matrix with every level you reach in the portal.

If you make a winning combination with these, you win an additional booster:

  • Abyss: a row or column with symbols is removed + 2 extra wilds
  • Void: a random symbol is removed + 2 extra wilds

Special wilds

There are special wilds that always activate a booster.

And lastly, there are multiplier wilds with the likeness of Rich Wilde on them. These double the payout on that combination.

Are you starting to feel a bit dizzy? Honestly, we felt the same. Sometimes there is so much happening during and after a spin that, pretty quickly, you have no idea anymore of what exactly is going on.

Is that a terrible thing? Not at all. It is just a question of playing the slot for a while, and then at some point, the penny will drop. Or not, and unfortunately, we can’t help, that is up to you.

Free spin bonus:

Did you manage to fill the whole portal? Then you win the main bonus feature.

You receive free spins where you are guaranteed to receive an Abyss or a Void feature. The more you fill the portal, the more boosters you win (minimum 3 and maximum 7).

During the free spins, there are several eyes you can find on the screen. If you manage to activate all of them with winning combinations, then the final big monster appears; the Mega Wild.

This kind of giant, moving octopus-like creature bears some resemblance to that fantastic Gargantoon that we all know and love from Reactoonz.

As this monster is called, the Cthulhu travels from the top downwards and gets you guaranteed big payouts as long as it remains on the screen.

A brilliant move by Play ‘n GO: you work towards a climax, and because it is never sure you will win it, it adds plenty of excitement to the game.

Our verdict on the Tome of Madness video slot

Play ‘n GO releases another top-notch video slot with Tome of Madness.

Everything we enjoy while gambling embodies this online slot: a cool theme, lots of surprises, progressive bonus features, and the possibility to win substantial sums of money.

A gem of a slot that many other providers can only envy.

4 out of 5 stars.
