About The Slot
So, the game starts out by introducing the main character, Jungle Jim. This good-looking explorer leads you to the game boards. The game is laid out in a 5x3 reel configuration and there are 25 paylines. The number of lines wagered is fixed in this game, so you can only play around with your bet values.

Bets start at 25p in the Jungle Jim El Dorado slot. Players can raise the stakes up to £25 per spin. Needless to say, the game caters to players of all risk appetites. I also checked out the game’s technical specs. The game has a return to player percentage of 96-97% and the payout rate of 43%. Take it from me. As an experienced slot reviewer, I can assure you that these are great numbers. Basically, you’ll get a winning payline two out of five times. The game also pays out 97% of all wagers to players, on average.

Let’s walk through the symbols in the game. There are eight different symbols in all. In descending order of value, there’s a treasure chest, a statue, a dragon scepter, a flute and four different coloured gems. Wins can go up well over 3,000 times, but regular wins are about 2-10x in size. The Wild symbol is marked with the words “Jungle Jim”. As usual, it replaces all other symbols in a winning combination, except the scatter. There’s also a extra spin symbol, which is the talisman. We’ll go through more detail into the features soon.

How Does This Mobile Slot Perform?
Jungle Jim El Dorado showcases one of Microgaming’s most impressive graphic productions to date. The symbols are drawn to look truly lavish. However, I think what really made the slot is in how every gem looks like the real thing. The stones have a realistic sparkle, colour and weight, unlike the twinkling gems in many other slot games. The background music and artwork also do its part to take you deep into the jungle. There’s the sound of crickets and trickling water, animations of drizzling rain, lush greenery in the backdrop and the sorts. As expected, the game is available to play on all desktop, mobile and tablet devices.

Game Features: RollingReels, Win Multipliers, Extra Spins!
The game engine powering Jungle Jim El Dorado is one of Microgaming’s best. This slot features the ever popular Rolling Reels™ feature. If you haven’t heard of it before, you’re missing out. In a nutshell, Rolling Reels™ is all about consecutive wins and multipliers. The feature is activated after every win in the base game. Winning symbols will explode and clear the board. Then, more symbols will tumble above to fill these spaces.

It’s pretty much an extra chance of winning at no additional cost. If you get a consecutive win, the reels explode again and offer yet another chance of winning. This goes on and on until your luck runs out. It’s an extremely thrilling experience and you’ll be holding your breath every time to try and make it to the next level. I’ve only scored three consecutive wins so far; do let me know if you go any higher!

To make things even more interesting, the game throws multipliers into the mix too. The Multiplier Trail increases on every consecutive win, up to 5x in the base game and 15x during the extra spins. You can keep track of this with the meter at the top of the screen.

There are few interesting things to note here. There are not many slots in the market that give away multipliers during the base game, and definitely not as many as 15 times. Even fewer slots include both cascading reels and multipliers in the same game. It’s also extremely important to highlight that these cascading reels, consecutive wins and multipliers are all part of the base game. You don’t have to unlock any special symbol or mini game; the rewards just appear!

That’s not all. There are also extra spins to be won inside Jungle Jim El Dorado. You’d earn these by scoring three or more Scatter symbols (the talisman symbol) anywhere on the reels. These Scatter symbols do not have to line up on the same payline. Anyway, when three of these marvellous Scatter symbols appear, the game will immediately trigger 10 free games.

As mentioned above, the multipliers go into overdrive. Every win during the free games is multiplied by 3x; consecutive wins are further multiplied 6 to 15 times! The free games are retriggerable too, which means that you can score additional extra spins within free games. If you’re lucky enough to win multiple times, the game will keep up and reward you accordingly.

Jungle Jim — All About The Rolling Reels Feature
This Rolling Reels™  game feature is proprietary to Microgaming and there are only a handful of games in their lineup that include it. Of course, keen players would argue that the concept of consecutive wins is neither new nor exclusive to Microgaming. This feature is also known as cascading reels, avalanching reels or tumbling reels. However, I feel that no software developer makes it quite as rewarding as Microgaming does. The feature occurs frequently enough to actually have an effect on your bankroll.

Another criticism of the game is how similar it is to Gonzo’s Quest. For those that aren’t yet familiar, Gonzo’s Quest is a really popular online slot that was created back a few years back, also by Microgaming. The adventurer in that game, Gonzalo Pizarro also ventured into the Amazon jungle in the search of El Dorado. Gonzo’s Quest also employs the same game features. So, does this slot demonstrate Microgaming’s dwindling originality or its proven formula?

Well, the designers have just taken old mechanics that work and installed it in a brand new slot. Players are always browsing the “New Games” shelves of casinos and producing revamped versions of slots are one of the ways of keeping those shelves continuously restocked. You can just take comfort in the fact that the original slot, Gonzo’s Quest is among the UK’s most popular slots ever.
