Jungle Spirit: Call of the Wild is a 5-reel slot from NetEnt, released in March 2017. The base game gives you 243 ways to win across a 5x3 grid, but that expands to 1,024 ways during free spins when the reels grow to 5x4. RTP is 96.47%, volatility is high, and the maximum recorded win sits at 7,768x your stake.
Butterfly Boost - The Base Game Feature
The headline mechanic in the base game is the Butterfly Boost. When you land a winning combination, golden butterflies appear and expand between one and three of the winning symbols so they fill their entire reel. That extra coverage turns modest wins into something more substantial, and it triggers often enough to keep base game sessions interesting without needing to wait for free spins every time.
There are no wild symbols in Jungle Spirit. That is a deliberate design choice by NetEnt. The Butterfly Boost expansion mechanic does the same job, and the result is a cleaner-looking game where the feature feels less mechanical than a standard wild substitution.
Free Spins - Choose Your Animal Spirit
Three or more scatter symbols trigger the free spins round. Before the spins begin, you pick one of five animal spirits. Each gives a different spin count and risk level. The chosen animal becomes the only premium symbol on the reels during the feature, which focuses the expanding symbol mechanic considerably.
The five options are:
- Tiger - 4 free spins. The highest variance option in the feature. Fewer spins, but each one carries the biggest individual win potential when your chosen symbol fills reels.
- Elephant - 8 free spins. A step down from Tiger in variance, with more breathing room to build wins across the session.
- Bear - 12 free spins. A reasonable balance between spin count and win size. Good if you want a longer feature without dropping to the lower-variance picks.
- Crocodile - 16 free spins. More spins, smaller individual payouts, but better coverage for players who prefer to grind wins rather than chase a single large hit.
- Cobra - 20 free spins. The lowest variance option inside the feature and the one most likely to produce steady wins across a long spin sequence. The game's maximum recorded win of 7,768x was achieved in Cobra mode - the volume of spins compensating for the reduced per-spin potential.
During free spins, the reel grid expands from 5x3 to 5x4, bringing 1,024 ways to win into play. The Butterfly Boost applies throughout the feature, so your chosen animal symbol can still expand across full reels mid-spin. Retriggers are possible if you land more scatters during the bonus round.
RTP, Volatility and Hit Rate
The 96.47% RTP sits above the industry average for high-volatility slots. Hit frequency runs at around 17% - roughly one in six spins returns something in the base game - though many of those returns are small relative to the bet size.
High volatility is the correct overall label, but the free spins animal selection lets you dial that up or down within the bonus round itself. Tiger gives you a high-variance feature; Cobra smooths it out considerably. That player choice is unusual in slots at this price point and makes Jungle Spirit worth revisiting across multiple sessions rather than feeling identical each time.
Bet range runs from £0.20 to £100 per spin.
Theme and Design
The jungle setting holds up well for a 2017 release. Animals are rendered in detail against a dense canopy backdrop, and the sound design mixes tribal drums with ambient animal calls. NetEnt put real production budget into this one - the butterfly animations that trigger the expansion mechanic are smooth and satisfying rather than a distraction.
Premium symbols are the five animal spirits: tiger, elephant, bear, crocodile, and cobra. Lower-value symbols use the standard card ranks. The paytable skews strongly toward premium symbols, which is why the free spins animal selection matters - you are betting on one of those symbols dominating the feature board.
Jungle Spirit Megaways
NetEnt, now part of Evolution, released a Megaways variant of this game. Jungle Spirit Megaways runs on the Big Time Gaming engine with up to 117,649 ways to win, a 96.20% RTP, and a max win of 6,547x. An Avalanche mechanic and a Feature Buy option sit on top of the familiar animal spirit concept. The mechanics are substantially different - Megaways changes the reel height dynamically on every spin. Both versions are available at UK-licensed casinos. If you enjoy the original, the Megaways edition is worth a look, though the original carries the higher max win and a slightly better RTP.
Mobile Performance
Built in HTML5, Jungle Spirit scales to phone and tablet screens without any separate download or app. The reel expansion during free spins works cleanly on smaller screens. NetEnt's mobile build quality has been reliable across their catalogue for years, and this title is no exception.
Verdict
Jungle Spirit: Call of the Wild is one of NetEnt's stronger mid-catalogue releases. The Butterfly Boost keeps base game sessions engaging without relying on frequent bonus triggers, and the animal spirit selection in free spins gives you a genuine strategic decision rather than passive feature play. High volatility means the base game can feel quiet between features, but the 17% hit rate prevents it becoming a patience test. If you favour high variance, go Tiger. If you want more spins and a steadier ride, Cobra is the pick.
