PropelX sends a fighter plane through clouds, lightning and unwelcome company, with two bets aboard and a growing multiplier to collect before disaster strikes.
Released on 29th June 2026, PropelX is a multiplayer crash game from SmartSoft Gaming. A fighter plane follows a flight path through danger zones, building a multiplier until an explosion brings the round to an end.
Clouds, lightning and a skull-marked fighter identify the hazards ahead. Players can place two separate wagers on the same flight, then collect manually or set an automatic cash-out target. Collection becomes available once the aircraft survives its first zone.
PropelX has a 97% RTP and a maximum multiplier of 1,000,000x, subject to a separate payment cap. Its compact presentation puts the flight, multiplier and betting controls at the centre of the game.
Choose your stake: Adjust the amount using the betting panel’s plus and minus controls, checking the limits available at your casino.
Add a second wager if wanted: The two panels let you place separate bets on the same round, with each collected individually.
Set automatic collection if required: Auto Cash Out accepts a target from 1.01x. It only settles the wager if the required multiplier is reached.
Confirm before take-off: Place your wager during the five-second betting countdown. Once the flight begins, that round’s betting window closes.
Pass the first danger zone: The plane progresses automatically. It must survive the opening zone before the Collect control becomes available.
Collect your return: Press Collect while your wager remains active to receive your stake multiplied by the cash-out value, subject to the payment cap.
Understand the losing outcome: If the aircraft explodes before your wager is collected, that wager and its accumulated potential return are lost.
Auto Play repeats bets automatically and can be enabled for one or both panels. It is separate from Auto Cash Out, which controls collection rather than placing the next wager.
The flight contains low-, medium- and high-risk zones. These are encountered along the route rather than chosen from a difficulty menu before betting.
Player activity, recent multipliers and betting history provide information around the flight. Previous results cannot predict the next outcome, and other players collecting does not tell you when to follow them.
PropelX gets the basics right immediately. It is clean, extremely simple and easy to understand, which suits the quick crash format well. We spent very little time trying to work out where anything belonged.
The aircraft is viewed from above, travelling along a vertical route against a dark, gridded background. Clouds and other hazard symbols sit ahead of it, while the multiplier remains prominent beneath the action. The two betting panels occupy their own clearly separated spaces below the flight.
That arrangement gives the game a distinctly mobile-first feel. The narrow play area, large buttons and clear separation between the wagers make sensible use of the available space. There is enough information to follow the round without the controls looking like a cockpit in their own right.
What we enjoyed most was how little effort the interface demanded. PropelX feels designed for someone who wants to open a crash game, understand the controls and get on with it. There is no sense that extra decoration has been squeezed in simply to make the screen look busier.
Its creative ambition is fairly modest. The aircraft theme covers familiar territory for the studio behind JetX, and the clean presentation gives it less individual character than some of the genre’s stranger ideas. Players looking for an elaborate setting or a succession of new things to discover may find it a little plain.
We had no particular complaints about that approach. PropelX knows the sort of experience it wants to provide, and the design supports it consistently. Its strongest quality is the ease of using it.

PropelX’s 97% RTP corresponds to a theoretical house edge of 3%. RTP describes the mathematical return over a very large volume of play; it does not promise that an individual session will return anything close to that percentage.
The maximum multiplier is 1,000,000x. However, the game also applies a separate per-bet payment cap and automatically collects when that limit is reached. The multiplier ceiling therefore does not mean every stake can receive a million times its value.
Check the casino’s monetary cap alongside its minimum and maximum stakes. A larger wager can reach a fixed payment limit at a lower multiplier, making that restriction particularly relevant when assessing the headline potential.
The opening zone deserves attention too. You cannot immediately collect after take-off: the aircraft must first survive that zone. An early explosion can therefore end the wager before manual collection becomes available.
Continuing through the flight allows the potential return to increase while leaving the active wager at risk. The low, medium and high-risk markers describe the dangers along the route, but they do not give you control over the outcome. The decision remains whether to collect an available return or continue.
Auto Cash Out follows your selected target only if the flight reaches it. It cannot prevent an earlier loss or remove the house edge. Likewise, two betting panels allow separate collection decisions but share the same flight result and do not improve the RTP.
PropelX delivers exactly what we want from a straightforward, mobile-first crash game. Its clean layout and uncomplicated controls make it easy to settle into, while the danger zones give the familiar aircraft theme a little extra character. Everything feels clear and purposeful, and we have few complaints about how it plays.
The modest feature set gives it limited appeal for anyone seeking something more adventurous, and the separate payment cap takes some shine off that enormous maximum multiplier. Still, PropelX handles the essentials well. Its simplicity is its strongest quality, making it a solid choice for players who prefer their crash games without much fuss.
PropelX has a 97% RTP, equivalent to a theoretical house edge of 3%. This is a long-term mathematical figure, not a guaranteed return for an individual session.
The maximum multiplier is 1,000,000x. A separate per-bet payment cap also applies, triggering automatic collection when reached, so check the monetary limit at your casino.
The low, medium and high-risk levels describe zones encountered during the flight rather than selectable difficulty settings. The aircraft progresses automatically, and collection becomes available after it survives the first zone.
