(AsiaGameHub) –   Players accessing William Hill’s online casino unexpectedly found large sums added to their accounts. In one reported instance, a user received a six-figure deposit. The company has moved quickly to limit the fallout, offering users the option to keep 11% of their windfalls if they agree to return the remaining amount.

The glitch appears to have originated on the platform’s Jackpot Drop game. After receiving the unexpectedly large payouts, a number of users immediately initiated withdrawals of the funds.

In response, William Hill sent emails asking users to return the incorrectly credited money. One email sent to affected users stated, “During a regular review of platform operations, we identified an issue impacting the Jackpot Drop game, which led to wrong amounts being added to players’ balances and withdrawals being processed improperly.”

The email further noted, “Our review has confirmed that specific balances added to your account and later withdrawn did not come from valid gameplay, and are linked to the issue affecting the Jackpot Drop game.”

William Hill noted that its Terms and Conditions grant it the right to void transactions, adjust account balances, and reclaim any funds paid out in error in cases where a game malfunction or technical error takes place.

Users Battle to Hold Onto Funds

Users shared screenshots of the unprecedented payouts across social media platforms. One user on X posted an image they claim belongs to their friend, showing the account had been credited with more than £140,000 ($188,000).

Another user reported that his grandfather had been credited £330,000 ($442,000) and had already withdrawn £33,000 of that sum. He alleges William Hill is threatening legal action if the funds that were withdrawn are not returned.

Past Rulings Have Sided With Users

In an earlier UK case, Corrine Durber had more than £1 million ($1.3 million) in winnings credited to her account for a Paddy Power casino game in October 2020. The gambling firm blamed a computer error and attempted to reduce the customer’s payout to just £20,000.

The case proceeded 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 places all risk on a consumer for its own recklessness, negligence, mistakes, insufficient digital services and inadequate testing, that appears overly burdensome to me.”

William Hill stated it is hopeful that customers will be cooperative and return the funds. A company spokesperson said, “We have reached out to relevant customers to clarify the issue, and are in the process of reclaiming the funds in accordance with our standard terms and conditions. We are thankful for our customers’ understanding of this situation.”

The platform faces an unclear future, with parent company Evoke announcing a strategic review last year following tax increases in the UK. The company has since delayed the publication of its financial results for the final quarter of 2025.
