Read Full BioUsers playing at William Hill’s online casino suddenly saw their accounts credited with huge sums. In one case, a user was credited with a six-figure sum. The company has rushed to contain the damage, offering users 11% of their winnings if they agree to return the rest.
The error appears to have occurred on the platform’s Jackpot Drop game. Upon receiving large payouts, some users quickly began withdrawing their winnings.
In response, William Hill sent emails requesting that users return the money. An email sent to users read, “During a routine review of platform activity, we identified an issue affecting the Jackpot Drop game, which resulted in incorrect sums being credited to players’ balances and withdrawals being processed incorrectly.”
It added, “Our review has confirmed that certain balances credited to your account and subsequently withdrawn did not arise from valid gameplay and are attributable to the issue affecting the Jackpot Drop game.”
William Hill said its Terms and Conditions allow it to void transactions, correct account balances, and recover any funds paid out incorrectly in instances where a game malfunction or technical error occurs.
Users Fight to Keep Funds
Users on social media posted screenshots of the unprecedented payouts. One user on X posted an image of what they say is their friend’s account, credited with over £140,000 ($188,000).
Another user said his grandfather won £330,000 ($442,000) and withdrew £33,000 of this. He claims William Hill is threatening legal action if the user does not return the funds they withdrew.
Previous Rulings Favor Users
In a previous case in the UK, Corrine Durber was credited with winning more than £1 million ($1.3 million) on a casino game at Paddy Power in October 2020. The gambling company blamed a computer error and attempted to reduce the customer’s winnings to £20,000.
The case went to court, and a judge eventually granted summary judgment in Durber’s favor last year, meaning she won without a trial.
In the ruling, the judge stated, “When a trader puts all the risk on a consumer for its own recklessness, negligence, errors, inadequate digital services and inadequate testing, that appears onerous to me.”
William Hill said it is hopeful that customers will be understanding and return the funds. A company spokesperson stated, “We have contacted relevant customers to clarify the issue, and are in the process of retrieving the funds in line with our standard terms and conditions. We have been grateful for our customers’ understanding on this matter.”
The platform faces an uncertain future, with parent company Evoke announcing a strategic review last year following tax rises in the UK. The company has since delayed the release of its financial results for the last quarter of 2025.
