As a player, your goal in PropelX is to safely pass through win zones to collect bigger multipliers. The sum of all collected multipliers equals your win, which must be cashed out to collect and secure. The catch? Any zone could be the one to crash your plane, resulting in a losing round and forfeiting your bet and any uncollected winnings! Here’s the steps to play PropelX from SmartSoft Gaming:
Step 1: Set your bet value
Press the “+” or “-” buttons to incrementally increase or decrease your bet amount, or expand the bet value menu to pick your bet size from the list. Using the keypad is the easiest way to quickly set exact amounts. PropelX features a dual betting panel, where two simultaneous bets can run on a single round, each with individual configurations and values.

Step 2: Press BET to wager
Between rounds there is a 5 second window to commit bets. The BET button will change to say BET ACCEPTED when you successfully wager your amount.
Step 3: Watch the flight path
This is where the game really starts! The pre-round countdown will complete and the plane will start moving forward along the flight path. You’ll notice the BET button is now yellow and reads COLLECT.
As the plane travels forward it will encounter 3 different types of zones. Zones are were you collect more win multipliers to add to your total cash out potential. The three zones not only have different risk levels, but also award different multipliers.
- Low risk – the highest probability of passing without a crash. Awards the smallest win multipliers.
- Medium risk – slightly riskier to pass without a crash, awards a bigger win multiplier.
- High risk – the most challenging and low probability zone to safely pass. Awards the largest win multipliers of all zones.
If you successfully pass a zone without crashing, a random multiplier value is added to your total win counter. This win counter total is indicated in real time on the COLLECT button at the bottom of the game page. Your win counter will always start at ×1.00 and increase with each consecutive zone you safely pass.

Step 4: Cash out or fly onwards
When you’ve passed at least 1 zone safely, you have a choice to make – cash out the total and collect your winnings, or, let the plane fly onwards and try to pass more zones. Remember, each and every zone could be the one to crash your plane. If this happens you immediately lose the round and your win counter is wiped. Timing your cash out is critical to being successful in PropelX.
Luckily, you can make a judgement call based on the upcoming zones. If you have a big win counter and see a High risk zone approaching, you might consider cashing out. If you haven’t passed many zones and only see Low risk zones, chances are in your favour to increase your win more – you might choose to push on!
The default theoretical Return to Player (RTP) is 97.0% and the maximum multiplier is ×1,000,000.
Below are the key game features of PropelX by SmartSoft:

PropelX is developed on HTML5 and JavaScript, which means your game will run flawlessly on most modern mobile browsers. You don’t need to download anything, simply launch the game from your browser and start playing. PropelX uses the same mobile portrait display view on PC versions with a black border to fill the widescreen display. This game is a mobile-first design.
PropelX is a truly mobile-first, lightweight crash game with a very low barrier of entry to learn and start enjoying. The key takeaway here is the creative risk level mechanic with the three Zones.
In the classic crash experience there isn’t any indicator for the upcoming crash point. Completely random and utterly butt clenching. However in PropelX, each approaching zone could be a crash point. Therefore, the plane can not crash between zones. Also, the probability of a crash is relative to the zone risk level.
This is unique and in some ways, an upgrade to the standard crash model. The suspense feels different because you can see the potential crash risk in real time as it approaches. As well, the win counter can dramatically escalate a lot quicker than the classic curve crash game because of the zones. Encountering several High risk zones in a row can send your cash out potential sky high in a matter of moments due to their large win multiplier rewards.
