At first glance, it looks like another typical Endorphina slot – a 5x3 board, 20 lines, gamble feature. However, there are some details that make the slot special. A max win of x25,000 is very impressive!
Freebies are the juiciest part of the game due to expanding wilds + random multipliers. The best strategy here is trying to catch FS. Yeah, slot can be pretty harsh with its down streaks. Patches without a single x5 win can last 200+ rolls. But freebies can easily make up for it.

A kind of classic 5 reels slot dedicated to some mystics. It offers fs rounds powered by multipliers and expanding wild. This somehow reminds me of the classic version Book of Ra slot by Novomatic. Anyway FS round is all right, it triggers quite often and brings decent hits. Also there is a good chance to have 12 extra fs. One time I have collected 36 FS in total!
To sum it up I would recommend you to try this slot, probably you'll enjoy the bonus round as I did:)
