Bison Bonanza: Slot Verdict Okay, fair enough, what we are dealing with here is essentially Sweet Bonanza with critters instead of candy. That's an inescapable fact, so if these similarities are a hard no for you, then Bison Bonanza is as guilty of being an ersatz impersonation as any other. We've seen Hacksaw do this pgslot auto as well with Joker Bombs and The Bowery Boys, and Blueprint themselves have even used the format before in Deal or No Deal Banker's Bonanza, so the trend is well established. It could even be argued Blueprint hasn't been particularly imaginative in its choice of theme. You don't need us to tell you how many North American wildlife slots dot the marketplace already, particularly those fronted with buffalo. If you can overlook these things or just couldn't care less anyway, Bison Bonanza is a real stampede of a game, with plenty to get stuck into.
