Factor X features

Somewhere far, far away in the depths of an undiscovered galaxy, there’s a world of star wins just waiting to be found. Jump in your rocket and join PocketWin Casino on an epic space-exploration adventure in Factor X mobile slots, and see if your fortune is waiting beyond the Milky Way.

Factor X features 15 win lines, an intergalactic mini-game and a progressive Jackpot that’s rising faster than a space shuttle after lift-off. Why not step up and give it a go? We know you’ll rocket.

Spacesuit up and prepare for launch – this’ll be an experience that’s out of this world! Factor X is exclusive to PocketWin Casino, so you won’t find it anywhere else on the planet (or off it). Will you return to earth with our stellar progressive Jackpot? Watch this space.

Getting Started

Before you blast off on your trek through the stars, you should really planet! That means setting your total bet per spin using the control panel below the reels. Tap the ‘+’ and ‘-’ buttons to increase or decrease the number of lines you’re playing on, and how much you want to bet per line. They will be automatically multiplied together to determine your total bet, which will be clearly displayed in the ‘total bet’ box in the middle of your control panel.

You can bet anything from 2p up to £20 per line, so try a few combinations until you find one that’s right for you. For example, bet 10p on all 15 win lines and you’ll pay £1.50 per spin. Make it £1 per line on just 5 win lines and your total bet will be £5. When you’re happy, hit ‘Spin’ to launch your spaceship!

Piloting a space shuttle is something you’ll probably want to concentrate on, so it’s lucky that your control panel has an ‘Auto Spin’ button! Click it to set how many spins you want and it’ll keep going until they’re all done! You can also set a minimum credit level that you don’t want to drop below, and/or ask your ‘Auto Spins’ to stop if you have a single win above a certain amount. Want to go back to manual play? Just press ‘Stop’.

How to Play Factor X

When you’re happy that all your settings are sorted and your Factor X rocket is ready for launch, just hit ‘Spin’! The reels will spin through hyperspace and stop at random. If you spin enough matching symbols on an active line, you’re in for a win!

How many symbols you need depends on which ones they are. With some, you’ll only need 2 or more, while others will only be lucky if you spot 3+ on an active win line.

It’s easy to get lost in space, but you should be just fine as long as you remember that our win lines always pay from left to right. When you spin a cosmic win, you’ll see your winning lines highlighted, and your prize amount will appear on screen. Just to make sure you don’t drop your winnings into any black holes, we’ll automatically add them to your credit for safe-keeping.

Reel Wins

In space, no one can hear you scream – so you can celebrate your win as loudly as you like! And rightly so, because each win will earn you a multiplier of your original bet per line. Just how much you get depends on which symbols you’ve matched up, and how many of them, so check the in-game paytable for the full breakdown.

Only the highest win on any one line will be paid, so if you match up more than one set of symbols, the largest win will eclipse any others. Win on more than one line in a single spin though, and all of your prizes will be added up to make one big meteoric win!

Wild Symbols

You’ll see a lot of stars out here, but this one’s special! The green star Wild symbol can stand in for anything except mini-game or Free Spins symbols, so if you spot one on an active line, you could be Saturn a surprise win!

So if you spin a Wild next to two 9s in deep space, you’ll win the same as if you’d lined up three 9s in a row! We hate to bring you back down to Earth, but you can’t win the progressive Jackpot with a Wild in place of a Jackpot symbol.


Match up two or more mini-game symbols to enter the ‘Spin Wins’ mini-game and hit ‘Spin’ to start the first booster wheel. What you land on with your first spin will determine what you see on the second wheel:

  • If you land on a purple ‘Super’, ‘Mega’, ‘Ultra’ or ‘Hyper’ segment, the bonuses available on the next wheel will be multiplied by x2, x3, x4 or x5 respectively
  • Stop on a red segment with 1, 2, or 4 stars on it and on the next wheel, you’ll have 1, 2, or 4 extra win markers respectively, giving you more chances to win!
  • If the wheel stops on a blue, green, or orange ‘upgrade’ segment, all wins of that colour on the next wheel will be doubled

Now it’s time to ‘Spin’ the second wheel and see where it stops. You’re guaranteed a win, as you’ll collect whichever multiplier you land on. If you have more than one win marker, all of the multipliers you land on will be added together to determine your total win!

Bonus Free Spins

If you spot some red Free Spins symbols on your win line, you could be in for a free ride to the next galaxy! Get 3, 4, or 5 Free Spins symbols on an active win line and you’ll land 5, 7, or 9 free spins respectively.

You’ll be in hyperspace while your free spins are in play, so you won’t be able to adjust any settings. Your number of win lines and bet per line will be locked to the same as your previous spin, but don’t worry! Your new alien friends will foot the bill for these spins, so your credit won’t be affected.

If this is your first visit to the PocketWin Space Centre, you’ll get a FREE £5* welcome bonus when you create an account! If you decide to make a deposit, we’ll also match that 100%* up to £100, giving you double your deposit to play with. Join today and reach for the stars!

Progressive Jackpot

The occurrence of 5 (five) "JACKPOT" Jackpot symbols on an active win line awards a progressive Jackpot. The progressive Jackpot is available on any bet, with 0.005% of the bet being added to the progressive pot. There is no hidden reserve pot.

When the Jackpot is won, it is reset and begins to rise again. Simultaneous wins can occur, if another player wins the progressive Jackpot then a notification to this effect would occur BEFORE the current player was awarded the Jackpot.

The game Jackpot seed value is £2000, The Jackpot is individual for this game, it is not shared with any other games.

In the event of a communication error after a progressive win result has been determined and before it has been displayed on screen, the win amount will automatically be transferred to the player's account. While the game is live, the Jackpots cannot be terminated.
