Horses and antelope and buffalo, oh my! Get lost in the beauty of The Herd™, a majestic 40-line slot journey through the American grasslands, with a sweeping sound track to match. Watch for herds of buffalo symbols in the base game where big wins are celebrated with an amazing buffalo stampede. The rush intensifies during The Herd's free spin bonus feature triggered by a two-symbol scatter on reels three and five. Players spin will decide their free-spin fate with the spin of two reels including a chance to win up to 20 spins and up to 4x multiplier. Players are then invited to “Build Your Herd” where another spin awards added groups of antelope, horses, or buffalo to the reels, increasing the chance for a big win. Free spin events are loaded with retrigger opportunities with a chance to win up to 100 free spins!
