Paddy Power’s ‘Missing 13’ – time is running out for mystery jackpot winners

Thirteen customers were caught up in the same software glitch that wrongly denied one woman a £1m jackpot, a High Court case revealed. Now they could have just weeks to come forward.

Time is running out for 13 mystery Paddy Power customers caught up in a software glitch that wrongly denied one woman a £1.1million jackpot and they may not even know they were affected.

The customers were identified during the High Court case brought by Corrine Durber, after she was shown a £1,097,132.71 Monster Jackpot while playing Paddy Power’s Wild Hatter game in October 2020.

Corrine, a 54-year-old gardener from Gloucestershire, was paid just £20,265.14 – the Daily Jackpot – after Paddy Power told her that a computer error had caused the wrong prize to appear on her screen.

She refused to accept the explanation and spent five years fighting for the jackpot she believed she had won.

In March 2025, Mr Justice Ritchie ruled in Corrine’s favour, finding that she was entitled to the Monster Jackpot displayed to her.

Her award, together with interest, ultimately took the value of her victory to more than £1.5million.

But her legal battle uncovered an extraordinary revelation.

Corrine was not the only customer affected.

Evidence presented to the High Court revealed that 13 other customers had also been affected by the software problem and had apparently received smaller Daily Jackpot prizes.

In his judgment, Mr Justice Ritchie found that the jackpot displayed to Corrinne was the amount she was entitled to receive, applying the principle he described as “What You See Is What You Get” – WYSIWYG.

Paddy Power was ordered to pay the difference, with interest subsequently taking the value of Corrine’s victory above £1.5million.

During the case, evidence was given by Ashley Padgett, UK Director of Compliance for Paddy Power’s parent company, Flutter Entertainment.

A report about the IT problem had been made to the Gambling Commission on October 23, 2020, just days after Corrinne’s disputed win.

The evidence revealed that the problem had affected other customers.

Thirteen other Monster Jackpot winners had apparently received the smaller Daily Jackpot.

Four Betfair customers were also identified as having accepted smaller prizes than they may have been entitled to.

The evidence also indicated that the issue was not limited to Wild Hatter, with nine other games identified as potentially affected.

The identities of the 13 other customers have not been publicly revealed.It is therefore unclear what happened to each of them.
