A woman is suing Casino del Mar in Viña del Mar, Chile, for CLP 4.67bn ($4.7m) after the casino refused to pay a slot machine prize of CLP 3.816bn that she says she won in November 2025.
Casino del Mar said in court that the disputed amount was the result of a technical fault, arguing that the customer knew the amount displayed was not a legitimate win.
Lilian Tumani, the woman behind the lawsuit, filed an infraction complaint and a civil claim after the casino refused to pay the prize, and the case is now before the Third Local Police Court of Viña del Mar.
In its response, Casino del Mar argued that the machine’s displayed prize did not correspond to a valid win. The operator cited a technical report from manufacturer Konami Gaming, which it said identified a defect in the machine.
The casino also referred to a review by the Superintendencia de Casinos de Juego (SCJ), Chile’s gambling regulator. According to the company’s court filing, the regulator concluded in August 2026 that the amount resulted from abnormal machine behavior rather than recorded bets or approved payout limits.
Casino del Mar said it contacted the manufacturer, paid Tumani the credits she had accumulated and offered her the machine’s maximum payout, but she rejected the offer.
The operator has also challenged Tumani’s account of the incident by pointing to her gambling history. It said she had visited the casino since 2005 and held Platinum status, its highest customer loyalty tier. Between August 2021 and September 2026, she accumulated more than 1,350 hours of slot machine play and made more than 1.2 million plays, according to the company.
“The defendant knows today, and has always known, that the prize displayed by the slot machine was the result of an error,” the casino said in its court submission.
Tumani’s lawyer, Pablo Gómez, disputed the operator’s position, arguing that a machine should not be considered reliable for accepting wagers but unreliable when it displays a winning result.
Enjoy and Casinos de Chile have asked the court to dismiss the case against them. They argue that Casino del Mar currently operates the venue, holds its operating permit and maintains the contractual relationship with the customer. They also challenge the court’s jurisdiction over the civil claim.
Tumani’s legal team has also argued that Casino del Mar’s request to surrender its operating permit early could create a risk that assets would be removed from the business before any compensation is paid.
Viña del Mar’s casino tender attracted no bidders in August 2026. The current operator is expected to continue running the venue until 2028 while Chile’s gambling regulator prepares a new process
