At the beginning of the base game, reels 2,3 and 4 are covered with Tree Vines. When a Wild symbol appears in the reel as a winning combination and is covered by the Tree Vines, the Tree Vines covering that Wild symbol gets removed.

Once all the Tree Vines are removed, the Dragon Treasure feature is activated, awarding 8 Free Spins. Each Armour symbol that appears in the reel awards one additional Free Spin during the feature, but Armour symbols don't pay.
