Unlucky 13: The Shirt Swap Service for Bad Luck Bringing Jerseys 

Luck and superstition in sport go hand in hand, and with a huge year of sport ahead in 2026, we’re here to make sure bad omens don’t get in the way of your matchday experience. 

More than a third of UK sports fans admit they’re superstitious, with half openly believing in luck. And in the world of casinos and gambling, the number 13 has the worst reputation of them all. 

Of course, the dice and cards don’t care about superstition, but when luck is on the line, even the bravest gamblers don’t always want to test fate by backing number 13. For many players and fans, they see it as a straight-up jinx – and casinos know it. Some even lean into the superstition, skipping the 13th floor altogether from their designs!  

But this season, we’re putting an end to the ultimate bringer of bad luck; by helping you retire your very own number 13 jersey and bring positive energy to your beloved team all season long! 

No longer will you have to cheer on your team without tempting fate, as our Unlucky 13 Shirt Swap Service lets you ditch the curse, keep the confidence, and enjoy the game without a second thought. 

Please, take the shirt off my back. How does it work? 

Applying for the Service is easy! Submit your application below, send us your unlucky shirt and in return we will send you £50 towards a new adult Super League jersey of your choice, which will hopefully bring cup glory your team’s way this season (Terms and Conditions at the bottom of the page).   

Still interested, click here to apply! 

All that we ask in return is for you to let us know more about your superstitious beliefs when completing the application for the Service. After all, it is a team effort! 

Let’s work together & officially retire the number 13 in all UK sports 

Imagine a world without the number 13 in sport.  

No more superstitions. No more fear of bad luck. Wouldn’t that be lovely? 

We’re calling on you and every other superstitious fan across the UK to unite and speak up against fate itself by requesting the governing bodies of the UK’s biggest sports to temporarily retire the number 13 for the remainder of 2026. 

Yes, we know it’s a big ask, but all we’re really asking is for the Department for Culture, Media & Sport (DCMS) to encourage sporting bodies to remove the number 13 temporarily, for the betterment of all UK sports. 

That’s where you come in. 

By signing this petition, we’re giving you the platform for your voice to be heard, and you’ll help show the decision-makers in UK sport just how deeply superstition is woven into game-day routines. 

2026 is a huge year for sport. So let’s take fate into our own hands and retire the number 13 from events such as: the FIFA World Cup, domestic football & rugby competitions, and other flagship sporting events throughout the year. 

It’s only temporary. It’s mostly symbolic. But if it helps even one fan breathe easier on match day…isn’t it worth it?

Entrance opens from 8:00am GMT on February 2, 2026, and will close at 12:00pm GMT on March 2, 2026, or earlier if the total budget cap is reached, whichever occurs first.
