Wild Turkey is a pretty standard slot during the base game. But Wild Turkey becomes much more interesting during its free spins feature.
When you get 3 or more wild symbols anywhere on-screen you will start the free spins bonus.
And during free spins, those wild symbols will appear stacked on all reels. Giving you a much higher chance to get a nice win. And if a wild symbol appears stacked on the entire reel you even get 2 more free spins each time this happens.
So the free spins feature can pay out very good with all those stacked wilds and can also keep giving you more free spins.
