Guernsey beat 10-man Isle of Man 3-0 to win Island Games gold for the first time in 12 years.
Craig Young opened the scoring after eight minutes as he slotted home from 10 yards out.
Ross Allen doubled the lead 17 minutes later after pouncing on a loose ball in the 18 yard box.
Dominic McGreevy was sent off for a second booking, before Kieran Mahon side-footed in the clincher after good work on the left by Matt Loaring.
Steve Sharman, Guernsey team manager: "It's really nice to get a gold medal, but really nice to get it in a way like that, with intelligent football.
"From our point of view we were clinical with our chances and we had a fantastic goal keeper who did his job. His job is not to look pretty but to save goals and that is what he did."
It is the third time that Guernsey have won gold at the Island Games, emulating their wins in 2001 and 2003.
They lost the 2005 and 2011 finals, and won bronze in 2009.
