Wild Wild West: The Great Train Heist™ is a 5 reel, 3 row, 10 fixed payline video slot with free spins, four wild features and a bonus round. Maximum payout for this slot is only 10x 5OAK wilds on a 50x bet, which is the equivalent of 500x stake. Not particularly high, but regularly achievable. Possible payout is only between 5x - 50x, not outstandingly high but OK to keep you hooked. The bonus round is triggered when 3, 4 or 5 scatters land anywhere on the screen, awarding 10, 20 or 30 free spins with unlimited retriggers.
High single line win is only 50x bet, a far cry from similar 10 line games like Book of Ra or Book of Dead. Wild Wild West: The Great Train Heist™ has more of a low to medium variance.
