Thousands in Norway told they won up to millions in lottery error

Scores of Norwegians thought they had become millionaires after
receiving a notification from the state-owned gambling company saying
they had won eye-watering sums - until it turned out it was a mistake.

"Several thousand" people who won prizes in the Eurojackpot were
notified of incorrect amounts on Friday, Norsk Tipping said. The
company declined to confirm the exact number of those impacted to the
BBC.

Norsk Tipping CEO Tonje Sagstuen apologised and resigned a day later.

Some 10+...iirc...winners for the jackpot.  Each got a piece of the
jackpot, but I suspect some had high expectations of being the winner.
