Rich Wilde and the Tome of Madness is based on another with an explorer on a mission. This slot is based on cascading reels and you form winnings by getting 4 or more matching symbols in a connected cluster either vertically or horizontally, similar like Gemix, Viking Runecraft and the likes. When you get a win, the contributing symbols are removed with new symbols falling in to give you continuous wins. Wins stop once there are no more winning clusters.
Symbols on the reels include 4 different colored stones as well as skulls, rings, daggers and pendants. The highest paying symbols give you 100 times your stake for a cluster of 10 or more symbols. If Rich Wilde himself for part of a win, your combo is multiplied x2.
Every win will contribute to the charge Portal (to the left of the reels) which unlocks several bonus features. There are 4 stages on the portal that release 2 wilds randomly on the reels to create more wins. Look out for the eye mark symbol which randomly land on the reels. Should a winning combination land on the eye of mark, it creates 2 additional wild and makes winnings even easier. There is a special Abyss and Void effect that each has its own feature to clear the grid and at the same time help filling the Portal charge.
If you manage to fill the charge the bonus feature is triggered with a set amount of portal effects. You can win up to 7 portal effects. Portal Effects are triggered when no more wins can be achieved, and these include:
• Special Wilds – 4 special wilds are added to the grid
• Abyss – 4 special wilds are added. If a win is formed with any special wild, the Abyss portal effect feature is triggered
• Void – 4 special wilds are added. If you get a win with any special wild, the Void portal effect feature comes into play.
Twelve Eye Marks are visible in the feature and if you generate wins on each of those locations you can release the Mega Wild Cthulhu. This is where you start winning some serious cash especially if base game wilds lands on the reels giving you the multiplier. This slot is nice but extremely highly volatile from what I can see. A lot of empty spins and bonuses pay on average between x20 – x50 your stake. If you do not get he mega wild, then there is no Mega win unfortunately.
