Slot Summary

Released in November 2019, Jungle Jim and the Lost Sphinx continues Stormcraft Studios' Jungle Jim series by moving the explorer into an Egyptian chapter. Its identity comes from cascading wins that advance a multiplier trail, eventually expanding the play area and opening more lines. Free spins alter that chase through collectible Sphinx symbols, giving the sequel a clear mechanical link between its adventure story and its escalating win sequence.
MechanicsCascading wins advance multipliers and unlock expanding reels

How It Plays

A paid spin begins with regular line evaluation. When a win lands, its symbols are removed, new symbols fall into their positions, and another win can continue the same sequence.

Three consecutive cascading wins expand the grid and raise the active line count. If the next reveal loses, the respin rule provides another attempt without immediately discarding the advanced multiplier position.

Theme & Atmosphere

Egypt supplies the Ancient and Exploration setting, with the lost Sphinx giving the adventure a specific objective rather than leaving the Tomb Raider influence as generic decoration.

The Jungle Jim character connects the Egyptian tomb expedition to the wider Action & Adventure identity, keeping the focus on an explorer advancing through a hazardous discovery.

Features & Win Potential

Cascading wins and the multiplier work together: each successful replacement can move the reward level higher, while expanding reels increase the available positions later in the sequence.

The respin protects a developed cascade at a key point, while the Wild Symbol and Scatter Symbol retain conventional supporting roles around the main multiplier chase.

Bonus & Free Spins

Free Spins begin on the expanded configuration with the multiplier already above its base starting point, shifting the round toward longer cascade chains and stronger multiplier values.

The Sphinx symbol collection adds further free spins and removes the lowest multiplier value from the trail, so each collected symbol improves the round's remaining baseline.

Bankroll survival simulator

How long could a bankroll last on Jungle Jim and the Lost Sphinx? We simulate thousands of sessions from this game's published RTP and volatility — the long-run math, not a prediction of your next spin.

Running simulation…
How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (High). The model is calibrated so the average return equals this slot's published RTP (96.30%), with wins capped at its top multiplier (6,250×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
