Landing 2 SCATTER symbols on any reel triggers a SONG FEATURE depending on the music. After ANY feature concludes, the next SONG FEATURE is chosen in the following sequence: DARK ROOTS OF EARTH, then THRONE OF THORNS, then COLD EMBRACE. The SONG FEATURE consists of 3 FREE SPINS, each with a different feature active. During DARK ROOTS OF EARTH, if a WILD symbol appears on the reels it will spread up or down. During COLD EMBRACE, if a WILD symbol appears on the reels it will be frozen in place on the reels for the remaining FREE SPINS. During THRONE OF THORNS the reels will expand to 4-5-6-5-4, with 2400 ways to win.
