The annual darts event, which raised £249,761, was won by the Royal Oak pub in Dorchester, who topped the table of 564 teams from 465 pubs across the country.
The competition supported CLIC Sargent, the cancer support charity for patients aged under 25 and their families.
The national final, held in Nottingham’s Trent Bridge Inn, saw the culmination of 81 area heats in January, followed by 12 regional finals held in February.
The Royal Oak emerged triumphant from the final 12 teams, beating the Bishop Vesey team from Sutton Coldfield by four games to three.
Team captain Colum Siddon said: “We weren’t exactly confident going into it because a couple of our players hadn’t played much darts before. But it was great to win.
“The final was really close actually. We went 3-1 ahead before they pulled it back to level. Then we just managed to win the last round.
“There was a great atmosphere and it was a good opportunity to meet other pubs. We will definitely be back to defend our trophy next year.”
Teams from the Brocket Arms, Wigan and Coronation Hall, Surbiton bowed out in the semi-finals of the competition. The George Inn, in Sandbach, the Yr Ieuan Ap Iago, in Aberdare, The White Hall Inn, Tiverton, and the Golden Bee, in Stratford Upon Avon were all knocked out in the quarter finals. The Bobbing Joan, in Alloa, the Robert Pocock in Gravesend, the Half Moon Inn, in Birmingham and Percy Shaw, in Halifax, were knocked out in group stages.
CLIC Sargent Lead Account Manager Sarah Colberg said: “We have to say a huge thank you to all of the hundreds of J D Wetherspoon staff who took part in this brilliant tournament.
“The final day saw some fantastic play and there was a brilliant, competitive atmosphere.
"This event has raised a huge sum of money, which will help CLIC Sargent fight for young lives struck by cancer.”
