Game features of Jungle Jim and the Lost Sphinx
Jungle Jim logo wild
The logo symbol acts as the wild for this slot when it surfaces on reels two through to five. This symbol substitutes for all others except the scatter and sphinx symbols.
Scatter wins
The scatter symbol can appear in any position, and we can earn 5x, 10x or 20x total bet (excluding boosted bet) with 3, 4 or 5+ symbols. The symbol only appears during the base game.
The slot has high volatility with an RTP of 96.10% to 96.30%.
Rolling Reels with Multiplier Trail
The Rolling Reels feature is a bonus game triggered by a payline win. In this feature, the symbols involved in the win are removed from the reels. This action creates gaps that are filled by symbols from above the reels for the chance to create new wins. If the shifting reels create a new win, then this process repeats until no new win is created. Each roll increases a win multiplier trail:
- 1st roll: 2x multiplier
- 2nd roll: 3x multiplier
- 3rd roll: 4x multiplier + 50 paylines upgrade
- 4th roll: 5x multiplier
- 5th+ roll: 10x multiplier
If no win is recorded on the 3rd roll, then a Second Chance Re-Spin is awarded.

Win Booster
The Win Booster is an optional feature in the main game at the cost of an extra bet of 3x current bet. It enables an additional scatter to increase the odds of triggering extra spins.
Features of the game include Multiplier Trail, extra spins with Multiplier Trail, Win Booster, Rolling Reels, scatter wins, wilds and more.
Extra spins with Multiplier Trail
The sphinx symbol can only appear on the 3rd reel during extra spins where it is collected giving rise to a shift of the remaining symbols. It awards an additional spin and increases the minimum multiplier value, thus increasing the multiplier trail until the maximum is reached. The win multiplier is as follows:
- 1st roll: 3x multiplier
- 2nd roll: 4x multiplier
- 3rd roll: 8x multiplier
- 4th roll: 12x multiplier
- 5th+ roll: 20 multiplier
The trail resets when a winning combination is not formed. The extra spins are played with 50 paylines and are triggered by 3 scatter symbols.
Ancient Egypt themed slots
Jungle Jim is a fun slot on the theme of ancient Egypt… among many others! If you don’t know which one to choose, I’ve put together a list of the top 5 clones of Book of Ra, a very popular slot with the same theme.
Jungle Jim and the Lost Sphinx opinion: Fun Game with Potential
Jungle Jim and the Lost Sphinx opinion is a decent little game that comes loaded with features. It’s got high volatility, so remember that a higher bankroll might be necessary and some of the features are difficult to trigger. Somewhat disappointingly, the artwork seems to have lost some of its edge when compared to the original. While this game is no Book of Dead from Play’n GO, which does more with less, the slot is entertaining with some big payout potential.
