Jungle Jim and the Lost Sphinx Game Review

Jungle Jim and the Lost Sphinx Game Review

Posted on November 15, 2023 by in Gambling

Micro gaming’s intrepid explorer Jungle Jim is here again. This time he is on a journey to Egypt to look for lost treasures and priceless artifacts.

Produced specially for Microgaming by Stormcraft Studios (Fortunium, Agent Jane Blonde, Dragon Shard) Jungle Jim and the Lost Sphinx is the long-awaited sequel to Jungle Jim El Dorado launched in 2016.

Jungle Jim and the Lost Sphinx is a supercharged version of the real game. The sequel takes pride in a substantially greater win potential, with extra features such as the Win Booster side-stake and Respins. Just like El Dorado, Rolling Reels and Multiplier Trails rest at the centre of this slots mechanic.

Rolling Reels (also reffered to as cascading or falling reels) is a well known feature found in many internet video games. Icons creating part of a triumphing combo explode and disappear from the reels, creating way for new signs to fall into the place from up. With any fortune, this ‘rolling’ action could potentially activate a series of consecutive achievements, all for one bet on a single spin. With each successful roll, the value of the Multiplier Trail heightens by one level. The greater the number of winning consecutive rolls, the greater the value of the multiplier prized.

The ground game begins as a 5×4 35 payline slot, nevertheless, there is a clever feature made into the Multiplier Trail that opens an additional row on the third consecutive roll, changing the base game into a 5×5 50 payline slot. The base slot multiplier levels are noted below:

Level 0 – 1x Multiplier (starting spin, 5×4 reels, 35 paylines)

Level 1 – 2x Multiplier

Level 2 – 3x Multiplier

Level 3 – 4x Multiplier (play upgrades to 5×5 reels, 50 paylines)

Level 4 – 5x Multiplier

Level 5 – 10x Multiplier

Another punter-friendly bonus created into the Multiplier Trail is the Respins Feature. If no win is prized after the third Roll (when the new row is opened) a single Respins is prized giving the punter a 2nd opportunity at continous further up the Multiplier Trail.

It’s thrilling to know the maximum multiplier in the Base Game is 10 times, two times that of El Dorado’s 5 times maximum multiplier.

The Win Booster is a side-wager feature we have come across earlier in Fortunium but functions alittle different in Jungle Jim and the Lost Sphinx. Clicking on the Win Booster heightens your total stake by 4x, and opens a bonus Scatter sign visible above the Win Booster button. Triggering the Win Booster substantially heightens your opportunities of activating Free Spins because only two Scatter signs are needed to activate twelve Free Spins (in place of three Scatters needed in constant mode).

Game Symbols

The Egyptian title is taken through to the beautifully crafted high-end game signs, while the beautiful gemstones are reminiscent of those featured in El Dorado; a nostalgic nod to the real slot maybe? The Jungle Jim element is Wild, and substitutes for all signs (apart from the Scatter) and assists to complete winning combos. Wild signs show up only on reels 2, 3, 4 and 5.

Three or more Scatter signs will activate the Free Spins Bonus and Scatters also possses a cash value.

The payment values for five signs on a triumphing payline are as shown below:

Scatter – 20 times total stake

Jim – 10 times total stake

Book – 5 times total stake

Chest – 4 times total stake

Pot – 2.5 times total stake

Red Gem – 1.2 times total stake

Orange Gem – 1.2 times total stake

Green Gem – 1 time total stake

Blue Gem – 1 time total stake

While these payments may appear low at first sight, put in mind this is a Rolling Reels slot, and there is a chance these triumphing values will be promoted by the Multiplier Trail.

Free Spins in Jungle Jim and the Lost Sphinx Participating in normal (unboosted) mode, three or more Scatters landing anywhere on the reels will activate twelve Free Spins. Engaging the Win Booster at a cost of 4 times your wager implies that punters will only require to land two Scatters on the reels to open the Free Spins feature. When the Free Spins Bonus is activated, we witness Jungle Jim hastening onto the display and rappelling down into the private chamber of the Lost Sphinx.

The Free Spins Bonus acts out on a 5×5 reel grid with fifty fixed paylines. Facing up the reels, punters will take note that the Multiplier Trail has heightend in value, with an nice maximum multiplier of 20 times. Once more, this is an improvement on the real El Dorado Free Spins Bonus which provides ten free spins with a maximum multiplier of 15 times.

Another extra to the Free Spins Feature is the collectible Golden Sphinx sign. If a Golden Sphinx sign lands on reel three, and extra spin is prized, and the Multiplier Trail is upgraded to begin one level higher. For example, if a punter lands a Golden Sphinx element for the first time, it will close in the Level one multiplier (3 times), implying that the Multiplier Trail now begins at level two (4 times). It is a nice feature that could improve the win potential, and also increase some expectance and fun to the Free Spins Bonus.

The 20 times Multiplier Trail implies that the win potential in Free Spins is 6250 times!
