One Friday evening the national lottery operator’s Norsk Tipping subscribers were alerted they had struck it rich in the Eurojackpot drawing. Soon after, however, gamblers were notified that their big money prizes were declared by mistake caused by a “manual error” in the company’s currency conversion system.

“Norsk Tipping receives prize values from Germany in Eurocents, which we then convert to Norwegian kroner. During this conversion process, a manual coding mistake was made in our gaming system”, — the company explained in a statement released the following day.

The operator revealed that prize amounts had been mistakenly multiplied by 100 rather than divided by 100, causing players to think they had won far larger sums than reality.

“We removed the false prize figures from our website and mobile app Friday night”, — Norsk Tipping stated. Accurate winnings were distributed around 3:15 a.m. local time, and the process finished by roughly 4:30 a.m. The company confirmed no players actually received incorrect payments.

Many Norwegians had already begun planning how to spend their phantom fortunes, including one couple who thought they’d won 1.2 million kroner (€/$  118,901) while in the middle of home renovations, according to The Guardian.

Another player believed they had claimed 1.9 million kroner (€/$ 188,260) in the mix-up. “It was very fun for a minute”, — Lise Naustdal commented to the publication.
