70-somethings Wenda Douthwaite, Arthur Beasley, Norman Stone and Ron Cole were playing at a village hall in Warwickshire when the extraordinary feat occurred.
The probability of four players each receiving all of one suit are 2,235,197,406,895,366,368,301,559,999-to-1.
Cole told The Mirror: "I shuffled the cards a number of times like I always do. I then passed the deck to Alan, who cut them. And he passed the cards back to me to deal."
Douthwaite added: "As soon as I picked up my hand I saw I had a complete set of spades. We laid our cards on the table and Arthur had all the hearts, Norman the diamonds and Ron the clubs.
She added: "They weren't in order but they were all there."
