Wolf Gold by Pragmatic Play Free Play ⚡ Full review of this 5 reels & 25 lines slot ⚡ Including Big Win Video and where to play for real money. The games are fast, always working perfectly. They are remarkable in creating casino-style games (the wolves were one of my favorites in the Rainbow Casino). When you hit a bonus or extra free spins, the auto-play feature turns off. It is a bit difficult to win when you bet high and I'm sure that is to entice players. .
