The Phuket Vagabonds just failed to make the cup final when they lost to the Sri Lankan 7s champions UC Lions 10-5 after extra time in the semi-finals earlier on Sunday.
Tournament organiser Pat Cotter said the event at the Thanyapura Sports and Leisure Club on Friday and over the weekend had been "a great weekend of rugby at a great venue."
Hundreds of players and more than two dozen teams took part in this year's main and veterans tournaments, as well as a youth Rugby tournament featuring the Phuket Lomas.
Matches from the different tournaments smoothly alternated on the pitch at Thanyapura over the weekend, so the final games were all played on Sunday afternoon. The surface of Thanyapura's well-drained artificial pitch showed its mettle when a monsoom storm let loose without troubling the players.
The Phuket International Rugby 10s tournament celebrated its fifteenth anniversary on the island this year, and Mr Cotter said the organisers were already looking ahead to an even bigger event next year.
