Jungle Spirit: Call of the Wild is a 2017 NetEnt release that uses a rainforest theme as the backdrop for one of the studio’s more exciting high-volatility offerings. It has a real sense of tension that fits the setting.

Built on 243 ways rather than fixed paylines, the game immerses players in a lush jungle environment with detailed wildlife symbols and atmospheric sound design. Bets range from $0.20 to $400, placing it firmly in the mid-to-high tier. The adventure angle feels genuinely earned here — the animals on the reels are specific and well-drawn rather than generic clip art.

Two features define the experience. The Butterfly Boost mechanic fires randomly during the base game, expanding a symbol to fill two or three positions and boosting the odds of a strong hit without warning. Free Spins add a more strategic layer: before they begin, you choose one of the featured animals to act as an expanding symbol throughout the round. Whichever animal you pick fills entire reels when it lands, turning the free spins into a tense streak-based experience depending on how often your chosen symbol appears.

RTP is 96.47% and volatility is high, which means sessions can involve dry patches before the bigger wins arrive. The max win of 2,700x your stake is a meaningful ceiling that rewards patience when the game runs hot.

Jungle Spirit is a smart high-volatility slot with a feature structure that gives players real agency. It suits those who want more than a passive spinning experience and are comfortable with variance.
