Jungle Jim El Dorado

Microgaming’s Jungle Jim El Dorado is an incredibly fun 3D slot featuring a unique art style and cartoonish animations. Like the best 3D slots, Jungle Jim has a real adventure of a storyline but lucrative bonuses and the Microgaming Rolling Reels is the real selling point.

Rolling Reels certainly makes up for the lack of extensive features. Rolling Reels remove the winning symbols in a payline allowing for potentially more wins! Every time this occurs your multiplier grows and can reach as high as 5x your prize. An exciting RTP of 96-97% and the combination of free spins and rolling reels offers the potential for some monumental prizes.
