At first look, the Jungle Jim El Dorado slot machine feels a bit like deja vu. The backstory (an explorer out for gold in the El Dorado jungle) is one we've come across elsewhere. Although visually Jungle Jim looks a little different, with avalanche style reels and Aztec symbols, it's no surprise this one draws comparison with Gonzo's Quest from rival developers NetEnt.

But there's definitely a lot to be admired about Microgaming's own take on the jungle explorer theme. Plus, with an RTP that means this slot pays out 97% over its lifetime, the scope for making a profit here is one that's too tempting to ignore.

Symbols in the Jungle Jim El Dorado slot machine stay true to the ancient Aztec theme, with gold-filled treasure chests rubbing shoulders with totem poles, warrior masks, and exotic crystals, across 5 invisible avalanche reels.

Rolling Reels and Free Spins take the action up a notch in this Aztec, Microgaming video slot game. And it's during these special features that players could potentially land a multiplier capable of turning a single line bet into a win worth 15x that amount.

The Jungle Jim wild unlocks the rolling reels feature, where multiple winning matches can be made until the time runs out. Every time a winning combo connects, the symbols disappear and new ones drop into the space they've left vacant, giving players repeated opportunities to land wins without the reels spinning again.

Find the circular symbol scatter and you'll enter free spins mode, starting off with 10 spins for every three scatters on the reels. If the rolling reels feature triggers during free spins, you'll receive a multiplier between x3 and x15 on your biggest payline wins. So there's big money to be made when either of these jungle Jim slot features come into play.

One of the best things about the Jungle Jim El Dorado online slot is the betting range. With stakes of between 25p to £25 possible, higher rollers have scope to play with, but not at the risk of alienating players whose gambling bankroll is more modest.

There's no additional incentive to play the maximum bet amounts here. So low rollers shouldn't fear missing out on any features reserved for higher paying players. Plus, with the possibility of landing a 3,680 x your stake win (with the free spins and multipliers attached) even a 25p bet can bring home a decent sized return.

Another area we put to the test during this Jungle Jim El Dorado slot review is the game's ability to deliver gameplay as optimally on mobile as on desktop PC and MAC. So, we tested Jungle Jim's compatibility with a range of smartphone and tablet devices including Android and iPhone. To see how the experience compared to playing at real money casinos online.

We found the mobile casinos offering Jungle Jim optimised perfectly with the limitations of the mobile devices we tested. Which included a range of Android and Apple handsets of differing generations. The results proved that, with a HTML ready device, Jungle Jim is readily available to play on mobile without compromising its graphics or any of the slot's main features.

The Jungle Jim El Dorado slot might not be original in its theme, but you don't have to be a fan of the explorer genre to enjoy everything this 25 payline machine has to offer.

There's enough action to keep you spinning those reels without getting tunnel vision (even on smaller screen sizes). And the 97% RTP ensures that wins crop up at an above average amount, which is beneficial whether you're playing the maximum betting limits or at more modest penny stakes.

So yes, this one does have echoes of other similar slot games, but with that 15X multiplier making it possible to win up to 3,680 times your stake, we won't let a little thing like that keep us from the big wins that Jungle Jim slot could (and frequently does) deliver.
