I hit this pretty nice free spins bonus at Cyber Club Casino. This game is great and the wilds also substitute for the bonus scatters (a bit unusual but certainly very helpful!)
This has to be one of the best NetEntertainment slots and is certainly one of my favourites. When you get a wild symbol (in the base game or during free spins) – after winnings are paid, the wild symbol(s) step one position to the left and again winnings are paid. This continues until there are no remaining wilds during the current game.
In the free spins bonus you can get enhanced wild symbols by collecting keys.
This was one of my best free spins rounds – I won £754.80 in the free spins bonus round for a £2 bet!
