Wow! Another spectacular win at Betfury. I played a lot of Money Train slots but never won anything big. It is one of the slots (specifically the later ones) where a single persistent symbol can give you the max win if landed on time. In later versions, you can buy this feature too, but it costs way too much for my taste.     
Anyway, congratulations to the winner. hope he will do something good for himself and his loved ones.
