I'd not heard of it before this week & it's not available on most casinos I play, but found Helios Fury on Videoslots.
Tossed £100 at it for a bit of craic.
100 spins @50p, then 100@80p, it held balance.
Raised it to £1 & it bonused quickly. I was £3 in front in the base before the bonus hit.
Hat tip to the Maestro, he knows his slots. I think I might invest in a 'hideous' amount of food next 😉
