Microgaming has launched Jungle Jim and the Lost Sphinx, the latest in a series of igaming slots developed exclusively by Stormcraft Studios.

Returning to action after his epic quest for lost treasure in El Dorado, Jim travels to the mysterious sands of Egypt in this five-by-four reel, 35-payline slot, which enhances to five-by-five reels and 50 paylines at key stages of the game.

Jungle Jim and the Lost Sphinx features Microgaming’s Rolling Reels and Win Booster mechanics, along with a multiplier trail that increases during free spins.

Set beneath a starry sky, the base game opens play to a five-by-four reel grid and a multiplier trail of up to 10x sat prominently above the reels. On each successive win, Rolling Reels blast away winning symbols as new symbols roll down, creating potential for further wins with increasing multipliers.

After three consecutive wins in the base game, the grid expands to a five-by-five configuration to unlock 15 extra paylines and award a 4x multiplier. A free respin is also awarded on a non-winning reveal.

When three scatter symbols land on the reels, players follow Jim, grappling hook in hand, as he lowers himself into the five-by-five reel, 50-payline chamber of the Lost Sphinx to reap the treasure of 12 free spins and a multiplier trail of up to 20x. The arrival of golden Sphinx symbols on the centre reel during the feature will help players in their bid to reach the 20x multiplier, as each Sphinx symbol collected awards an additional spin and upgrades the multiplier trail to start one level higher.

Players can significantly improve the frequency of free spins being triggered by activating Win Booster, during which only two scatter symbols are required to access the coveted feature.

James Buchanan, director of global operations at Microgaming, said: “We are so excited for the return of this iconic character in Jungle Jim and the Lost Sphinx. Jungle Jim is ready to dig up incredible rewards with win potential of up to 6,250x. The combination of innovative game mechanics and a graphically rich visual experience makes this latest instalment of Jungle Jim a game not to miss.”
