Slot Summary

Press Collect before the aircraft is destroyed: that decision defines PropelX, Smartsoft Gaming's aviation crash game. The climb passes through distinct danger zones, giving the flight a sequence of recognizable hazards. The accumulating award remains exposed until collection, so the central tension comes from deciding how much of the flight to attempt.
MechanicsCollect the multiplier before the aircraft crashes

How It Plays

Clouds, lightning, and a skull-marked fighter divide the route into different hazards. Clouds offer smaller multipliers and lower danger, while the fighter presents the greatest risk and reward.

Clearing a zone adds its multiplier to the running total. The upcoming zones are visible before the aircraft reaches them, providing context for the next collect-or-continue decision.

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 (Medium). The model is calibrated so the average return equals this slot's published RTP (97.00%), with wins capped at its top multiplier (1,000×).

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.

Yes. PropelX includes automated cash-outs as well as autoplay, so collection can follow a preset target.
