William Hill Error Sees Millions Paid Out — Players Offered 11% to Return Funds

Bookmaker William Hill has been hit by a major malfunction in a slot jackpot mechanism that led to players being credited with winnings totalling millions of pounds, Next.io reported.

The issue involved the Jackpot Drop feature — an additional slot jackpot that players can join during gameplay. At random intervals, the system selects a winner and awards a prize. However, due to a technical fault, the mechanism began operating incorrectly, with users seeing balances of tens and even hundreds of thousands of pounds.

Some players treated the amounts as legitimate winnings and were able to withdraw funds. Account balances showed significant sums — in some cases around £142,000 (approximately €168,000) and £236,000 (about €279,000).

Screenshots of such balances quickly spread on social media.

After identifying the issue, the operator blocked the affected accounts and disabled the faulty feature.

The company is now seeking to recover the funds. In communications to customers, William Hill cited terms and conditions allowing payouts to be voided in the event of technical errors and requested that the money be returned.

At the same time, a compromise is being offered: users are allowed to retain around 11% of the withdrawn amount if they voluntarily return the remainder.

The situation may lead to legal disputes. Some players have already indicated their intention to challenge the operator’s demands, with the outcome likely to depend on the wording of the terms and the circumstances under which the funds were credited.

Earlier, Gambling Park reported that Betfred and Bally’s were considering buying William Hill shops in the UK.
