A kinda creepy slot. It’s not like you’ll see some scary graphics or animations here. But all those symbols and even backround pic are creepy in their own unique way. Well done to designers.
Slot’s main feature is free spins, where additional random multiplier may appear. It can take pretty long before u trigger them. Slot tends to switch from cold mood to hot and vice versa.
Base spins…well even x10 wins are rare here. But once in a while slot produces almost a full board of a kind.

A mystic slot full of creepy creatures. The slot features a single free spins round. It is said that you may trigger extra multipliers in the bonus round but I haven't landed it. The base game has lots of dead or low paying spins and the max win I reached was not higher than 10x. I think the slot lacks some extra features to make the process more exciting. The bonus round contains of 10 spins and 9 of them were empty just the last one brought the sum on the screenshot:D

Cthulhu theme is quite interesting and ancient. Graphics and symbol art might look a little bit creepy and really unorthodox. I can't really figure this slot out, to be honest, since there are moments where every spins you make are paying, usually your bet size, sometimes lower and rarely higher than bet size. Then there are moments when completely nothing happens and the slot is claimed to be medium volatility, which doesn't seem to be the case. FS are nothing special regarding features. Meeh
