Four card-playing friends were stunned to pick up identical straight run hands in a bizarre 61 billion-to-one fluke.
Lady luck was definitely at the table when the increasingly amazed foursome started to sort through their 13-card hands.
Each found he had a run of cards from an ace through to the 10 and completed with a jack, queen, king flourish.
The freak outcome happened last week as Owen Williams, Meirion Hopkins, Ieuan Griffiths and Mike Harwood sat down to play a game called Crush at Brynamman Industrial Club near Ammanford, South Wales.
They were so intrigued by the outlandish outcome they called Cardiff School of Mathematics to find out what the odds were.
Lecturer Rhyd Lewis astonished them further by calculating the odds at a breathtaking 61,204,166,001 to one.
"I was just amazed when I sorted my cards and realised what I had," said Mr Williams, 63, a commercial finance broker.
"It was the first deal of the evening and I was the first one to finish sorting my cards. A run through takes the kitty - so I thought I'd won £1.65."
But as the other players sorted their own hands, each found he had an identical mixed suit run. The friends were so amazed at the outcome they called over other club members to witness the four hands.
Mr Owen insisted the group had been playing with a "well-used pack of cards which were cut and shuffled in the normal way", before being dealt.
