Wild Life is all about the Free Spins Bonus feature, which is played when you get 3 or more African scatter symbols anywhere on the reels. 3 will provide you with 10 free spins and 4 free spins for 4 times. If you get 5, you will get 20 free spins.
The wild symbol is more important in this feature - again, it appears on the 3 intermediate reels (2, 3 and 4) and also expands to take over the entire reel. However, once the reel is wild, it remains locked for the duration of the feature! If you get them early, be prepared to make your own free spins with a total bet of 1,030 times the roaring victory.
