Design-wise, the Jungle Jim and the Lost Sphinx is an eye-catching title, but as usual, we are more concerned about the gameplay details, so let’s jump to the features that will make your wallet plump.

Jungle Jim and the Lost Sphinx - Slot Review

The Jungle Jim and the Lost Sphinx is a 5-reel, 35-payline (50-payline when expanded) slot that accepts bets in the range 0.10 – £20 per spin. The slot tells the story of the adventurer Jim who goes to the Valley of the Kings to find a hidden treasure. Yes, this is an Egyptian flavour slot packed to the brim with cool features.

The pay symbols you will land on the reels include treasure chests, gemstones, a book, pots. Jim himself is the best payer giving you 10x your stake for 5 OAK. The game logo is the wild that performs its standard symbol replacement duties.

Rolling Reels Feature

Every game studio has a different name for that feature. Microgaming calls it Rolling Reels, Blueprint calls it Cascading Reels, NetEnt prefers the term Avalanche. To cut the long story short, the symbols that form winning clusters disappear from the grid.

They are replaced by new ones that may eventually form yet another winning cluster and so on. Technically, the rolling reels mechanics enables you to land several (hundred) wins in just one spin. However, this time around Microgaming has added a nice improvement to the original version. You level up with every winning reaction:

Default level – 5-reel, 35-payline reel set
Level 1 – 2x multiplier
Level 2 – 3x multiplier
Level 3 – 4x multiplier + extended reel set (50 paylines)
Level 4 – 5x multiplier
Level 5 – 10x multiplier

Second Chance Respin Feature

In most slots, a losing spin would revert the multiplier back to 1. However, the Second Chance Respin feature not only allows you to keep your progress but also to level up. The feature comes to your rescue after the third winning cascade. If you have a losing spin, you get a respin i.e a second chance to land a winning combination and level up.

Free Spins and Win Booster

Three or more scatters in one spin trigger the feature and you win 12 free spins. If you wish, you can take advantage of the Win Bolster option and unlock an extra scatter that increases your chances of triggering the free spins round. The feature is played on an extended 50-payline reel set. During the free spins round, the Rolling Reels feature offers better multipliers reaching to 20x for the 5th level.

Bottom Line

If you are familiar with the original, you will feel right at home with the sequel. Although we have seen some negative comments about the Jungle Jim and the Lost Sphinx, it all comes down to personal preferences and we are positive that this is one of the best slots Microgaming has released lately.
