William Hill UK is asking an unknown number of customers to return what could be a significant sum of money after a software glitch in one of its slot-style games awarded huge jackpots in error.

Multiple players of the Jackpot Drop game are understood to have received the erroneous payouts, with several posting online that they amounted to six-figure sums.

One Reddit user claimed their father had “won” roughly £250,000 (~US$336,000), before the Evoke-owned operator froze his account. An X user posted a screenshot of a friend’s account showing a balance of £141,897 (~US$190,000), also frozen. Dozens of social media users have reported similar experiences, suggesting the erroneous payouts could run into the millions of pounds.

Cap in Hand

The operator is now asking for funds that were withdrawn into customer bank accounts before accounts were frozen to be returned, on the basis that the payouts “did not arise from valid gameplay.”

According to the Reddit post, William Hill sent the following message to the user’s father:

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.

“As a consequence of this issue, funds were incorrectly credited and, in some cases, withdrawn from a number of customer accounts, including yours, that were not generated through valid or properly functioning gameplay.”

Random by Nature

A possible problem for William Hill is that Jackpot Drop is a progressive slot-style game that “drops” jackpots at random. That’s different from a traditional progressive where big wins are tied to a specific in-game event, such as hitting a top symbol combination or winning a bonus round.

In Jackpot Drop, payouts are expected to be dished out at random, which means players could argue they could not have reasonably known that an error had occurred.

William Hill is reportedly offering customers around 11% of withdrawn funds as a settlement, asking for the remainder to be returned. That may prove difficult for some players, particularly if the money has already been spent on debts or mortgages, for example.

UK Courts Shift Toward Players

This one is likely headed for the courts, which often used to side with operators because small print inevitably asserts that malfunctions void all plays and pays. However, London’s High Court has proven to be a more player-friendly battleground in recent years.

In March 2026, the High Court ordered Paddy Power to pay out a £1.1 million (~US$1.4 million) jackpot after the operator argued the player had been shown an incorrect winning animation due to a software error.
