Doritos Epic Night In-In £100,000 giveaway!

Good news for Doritos fans – they’re giving away £100 cash to a thousand lucky winners! But they don’t want you to go Out-Out – instead, they’re giving away cash so you can treat yourself to an Epic Night In-In!

Look out for a promotional Doritos packet in your local supermarket, then enter the unique code from the back of the packet online to see if you’re an instant winner!

How to enter the Doritos instant win

  • Buy a promotional bag of Doritos with the ‘Win £100’ flash (it’s on the 180g sharing bags of Tangy Cheese, Chilli Heatwave, Cool Original, Pepperoni Pizza & Triple Cheese Pizza, plus the 150g bags of Tangy Cheese, Chilli Heatwave & Cool Original – and the 70g bag of Pepperoni Pizza flavour!)
  • Enter the batch code from the Best Before box (ten digits, beginning with G) at www.doritos.co.uk/nightinin
  • You’ll find out instantly if you’ve won, and winners will also receive an email.

You can enter once a day, and win one prize. Codes aren’t unique so you can use the same one multiple times, but keep in mind that you may be asked to show evidence of multiple receipts if you win! Winners will need to pass on their bank details to the promoter so they can be paid via BACS.

There are several issues at the start of this promotion, with valid codes not being accepted and error messages being shown. Hopefully these problems will be fixed soon!

What are the prizes?

  • Each winner gets £100 paid directly into their bank account – or the equivalent in Euros, for ROI winners.

The main instant win competition ends on 25 March 2023, but if you miss it don’t worry because there’s a late entry prize draw that closes on 30 May 2023 with fifty more £100 prizes!

About the winning moments format

The Epic Night In-In promotion has 950 winning moments in total – that’s one approximately every 100 minutes or so – and if you’re the first person to enter after one of these random winning moments, you’ll win a prize. This means that you can choose your entry time for the best chance of winning – overnight less people will be taking part, for example you’ll have a higher chance of hitting a winning moment between 1am and 6am.

The promotion is open to UK and ROI residents aged 18+, and Irish residents will need to answer a question on entry. Find full T&Cs on the main competition page at www.doritos.co.uk/nightinin

    Hi Di, You can enter multiple times with the same code for Doritos £100 win but have to show multiple receipts if you win more than once. Why would you get multiple receipts if you are using the same code and only purchased once?

    Same here, on the tangy cheese and pepperoni pizza flavours.

    Hi Di, i’m having issues getting my code accepted..keeps saying invalid suspicious entry

      I think a lot of people have this problem, but it seems to work if you leave 24 hours after your previous entry so you could try that!
