Jungle Jim El Dorado slot from Microgaming

Jungle Jim El Dorado slot from Microgaming
The charismatic Microgaming’s Jungle Jim is clearly a clone of the legendary NetEnt’s Gonzo, going on the same quest for Aztec treasures in the rainforest. These 2 adventurers from different eras might even run into each other (and become buddies off-screen).

Microgaming’s developers actually made it constantly rain in the backdrop. Now all you have to do is hope it will rain cash on you. Good odds it will, since the RTP of the Jungle Jim El Dorado slot machine (2016) is 96.31%, and a lot of features are present to enrich your chances. Win or lose, you will be entertained by Jungle Jim and his quirky reactions to your achievements on the reels. The Rolling Reels are actually not rolling but cascading. We advise you to try the Thunderstruck Wild Lightning slot by Microgaming for free.

This mechanism works in your favour, as winning combos dissolve and make room for the next symbols to fall in their places. This way, you don’t pay for the rolling after a successful spin, and you get another chance to win. Plus, it activates the Multiplier Trail, resulting in bigger and bigger payouts, as long as you keep getting hits. Accept the challenge and follow Jim on his epic quest for the lionized golden city of El Dorado.

Personal testers’ opinion

Imagine your surprise when you first launch the game. Wow, are we back in 2013? Isn’t this just NetEnt’s Gonzo? The same math model (above 92 000 coins maximum win, i.e. over 3600x the total bet is the ultimate jackpot), the same almost RTP, and identical gameplay!

We are extremely displeased when a developer is producing reskins (copying his own creations). Like dressing the body in a new swimming costume, then letting it swim in the same old lake, feeling pretty and fresh, but everybody knows these body curves and flaws - who are you trying to fool, actually?

And with clones, the providers really astound us! This not only feels like the same body in a new suit, but it is also a nasty snatched outfit! If it makes Microgaming sleep well, so who are we to protest against such practices? It will not be the last time a software company thieving, especially when somebody else's idea is genius!

Back to Jungle Jim El Dorado slot machine. We enjoyed testing it since we hit some big wins and also because Jim is perky and adorable. Every little thing he does, puts a smile on your face, even when you might be on a losing streak. The probability of hitting any win is equal to 42.55% (which is a high number, hence advantageous for the player), and 62% of the bets are set aside for payouts in the base game. Free Spins are launched every 142nd spin (0.71%), statistically, which is just a standard waiting nothing more, nothing less. Our average winning was 63x the bets in the bonus round. In the main game, we did better and reached a maximum winning of 510x total bets.

We do recommend sessions with real money, as the Jungle Jim El Dorado slot machine has proven potential for large payouts and because it is popular among many Microgaming fans (i.e. often hot, and the prize pool - ready to cut you out some sizable prize). However, the machine is certainly not suitable for completing the bonus requirements (3.51 out of 10).
