Jungle Spirit: Call of the Wild transports players deep into a lush, vibrant jungle inhabited by powerful wild animals. The game is known for its Symbol Expansion feature, where certain symbols can expand to cover an entire reel, and the Butterfly Boost feature, which randomly expands 1-3 symbols involved in a win. The highlight is the Free Spins bonus, where players choose their volatility by selecting from five animal options, each offering a different number of spins and transforming the reels into 1024 ways to win.
