Finally, a steampunk-themed online slot game by BF Games. This time, players will visit a huge city which is based on steampunk stories. This is a slot game that follows the rules of classic Online Slots, but it also has some extra features. So, in addition to the refined graphics, lovely animations and a bunch of basic symbols, Steampunk Big City also has a wild symbol which looks like a gun and replaces all basic symbols when necessary. The beautiful metallic butterfly is the Scatter symbol and three of them will provide 12 Free Spins where the wild symbol is stacked which means more chances for winning big prizes.
