Jungle Jim and the Lost Sphinx


Jungle Jim and the Lost Sphinx Slot Review

Jungle Jim and the Lost Sphinx is a video slot from Stormcraft Studios created exclusively for Microgaming. The game has 5 reels and 4 rows with 35 to 50 paylines. You can play this game at online casinos such as Unibet, Mr Green or Twin Casino.

Theme and general information

Apparently, it is time that Jungle Jim goes on another adventure. After having found El Dorado, he is now in Egypt, looking for treasure there. He doesn’t seem to have quite as much fun with it, only appearing occasionally when a win is created or to make a show of climbing down into the tomb when the free spins are triggered. He is still a charming character, but we would have liked to see more of him.

Also, what is it with sending all those slot adventurers to Egypt? Lara Croft’s latest adventure saw her there. Rich Wilde has been there. And we wouldn’t be surprised if ELK Studio’s Kane will end up in Egypt as well.

Egypt is a favoured theme, of course, and it lends itself to the adventurer theme as well. But we have seen more impressive slots than this Jungle Jim one. It is night-time and that means the scene is generally quite dark. The setup is also somewhat simple. The reels are framed by a temple that is sitting somewhere in the desert. Hieroglyphs adorn the temple, which is a nice touch.

On the reels we get some Egyptian artefacts (no gods or pharaohs for a change) such as a vase, a book (which is irritating since they wrote everything down on scrolls) and a chest. Jungle Jim himself is the highest-value symbol.

The low-value symbols are the same gemstones we know from the previous Jungle Jim slot. The wild symbol is the Jungle Jim slot symbol and the scatter is a sort of amulet that also reminds us of the scatter in the previous El Dorado slot. During the free spins, a special Sphinx symbol makes an appearance as well.

The wild is the most valuable symbol, paying out 20x our stake for 5 on a payline. Among the regular symbols, Jungle Jim pays out 10x our stake for such a win. The artefacts are worth between 2.5x and 5x our stake for 5 on a payline.

You can play this game from 0.10 to 20.00 per spin without the win booster and 0.40 to 80.00 per spin with the win booster.

Various base game features

Jungle Jim and the Lost Sphinx comes with Rolling Reels, which means we get cascading wins and symbol removals. Here, multipliers come into play with every consecutive win, which is always appreciated.

Once you hit the 3x multiplier and don’t score another winning combination, you get a free re-spin to help you along reach the 4x multiplier. If that 2nd chance spin is successful, the 5th row is unlocked, and you now play with 50 paylines in the base game. Further wins would give you a 5x and then a 10x multiplier, which can result in great base game wins as well.

You can only get the 2nd chance spin once per wager.

Additionally, there is a Win Booster in the game. You can see it to the left-hand side. If you activate it, your bet size actually quadruples, so you want to be careful here. It does have a useful purpose, however, as it gives you a scatter. Whilst the scatter sits outside the main reels, it will help to activate the free spins as long as you land two more scatters on the inside of the reels.

Upgraded rows and multipliers in the free spins

Triggering the free spins requires three scatters one way or another. When we tried the Win Booster, we managed to trigger the free spins after only a few spins, so we considered it worthwhile.

You get 12 free spins and the Sphinx symbol comes into play. Also, the multiplier is upgraded to 2, 3x, 4x, 8x, 12x and 20x.

Consecutive wins are made easier thanks to the full 50x paylines across 5 rows in play now and if you manage to get a Sphinx on the reels, it will not only give you an additional spin and it upgrades the multiplier to start at the next highest multiplier. So, now the multiplier starts at 3x as the 2x multiplier has essentially been removed.

The Sphinx can thus remove all other multiplier until you reach 20x, where it would then stop for the remainder of the spins you have.

Conclusion: Effective features but an unimpressive theme

The theoretical RTP (Return to Player) for Jungle Jim and the Lost Sphinx is 96.3%, which is good for a slot that has a volatility that ranges from medium to high.

At first glance, we were fairly unimpressed by this slot. It is too dark and muted and doesn’t really reflect the fun and adventurous spirit we love from Jungle Jim. There was just something a little dull about the theme, perhaps owed to the fact that we’ve seen some magnificent Egyptian-themed slots lately.

That aside, however, the gameplay is quite effective and engaging. It doesn’t get boring playing Jungle Jim and the Lost Sphinx. There is plenty happening to keep you going and you should haul in enough wins thanks to those multipliers to keep you interested for some time.
