Thunderbird Slots, by Rival Gaming is a new slot game and truly one of a kind. This is a five reel and 50 pay line video slot where you can bet as many as 10 coins per line. There are expanding wilds with a 2x multiplier during free spins and a Super Spirit Round triggered during the free spins and the first reel remains wild for the entire round. The theme is centered high atop a mountain on a nest of stone, which is where you will find the Thunderbird. The Thunderbird is a legendary creature in certain North American indigenous peoples' history and culture. It is considered a supernatural being of power and strength. It is especially important in the art, songs and oral histories of many Pacific Northwest Coast cultures.
Some of the symbols used in this slot game include a drum, a woven hat, fir cones, feathers, a bear mask, a face carving, a serpent, a fish, a storm maker, which is the Thunderbird, and the 10, J, Q, K, and A playing cards. The Thunderbird is the wild symbol during regular play but in free spins it is an expanding wild. Three or more of the Fish symbols will trigger the Free Spins Bonus Round. During the free spins if you get three or more of the Super Spirit Fish, you will then activate the Super Spirit where you will get the entire first reel as wild during the entire round. Five of the Fish symbol gets you 50 free spins, four gets you 20, and three gets you ten free spins.
