Cascading cluster-pays slot

This is a cascading slot in which symbols drop into the grid. When at least four or more identical symbols are touching vertically or horizontally on the reels then a win is created. The symbols involved explode which gives rise to symbols which fall to fill in the gaps. Explosions and new symbols fill the spaces which repeat, for free, providing new winning clusters are created.

Eye marks

Tome of Madness slot machine mark

Eye marks, similar to the Eye of Horus, may appear on any space. Opening an eye is done by a win in the location of the eye. When this happens then 2 special wilds are added once no more wins are reached.


This is a cluster-pays and 5x5 grid game which uses exciting features, colourful graphics and superb audio effects.

Abyss and the Void Portal

A portal draws its power from the energy of cluster wins. A cluster win on seven symbols will unleash two special wilds symbols. A cluster win on 14 symbols will unleash 2 special wilds. The Abyss Portal Effect is triggered with a win using a special wild. This portal will remove a column or row from the winning special wild symbol, which in turn charges the portal. A cluster win on 27 symbols will unleash 2 special wilds. The Void Portal Effect is triggered with a win using a special wild. This portal randomly selects a regular symbol to be removed from the grid.

Other World Free Rounds

A cluster win on 42 symbols will unleash the Other World Free Rounds. You will be awarded 1 free round with 3 random Portal Effects. Over-charging the portal results in an additional Portal Effect for every 3 additional winning symbols collected which is capped at seven total. The portal effects include 4 special wilds which are added to the grid, Abyss which adds four special wilds and Void which adds four special wilds. A special wild will trigger the Portal Abyss Effect or Void Portal Effect respectively. The Mega Wild Cthulhu is added to the grid when 11 or 12 Eye Marks are added. It shifts downwards on each cascade until disappearing.
