The youngest competitor was just 10 years old, while the oldest was in her 90s.

Dozens were involved in the two-day weekend event at Warrnambool's Deakin University campus, some from interstate and Victorian cities such as Traralgon.

Convener Jan Cooke said the games were "highly competitive" and won by experienced players from Melbourne, Geelong and Mount Gambier.

"It's great for the town, they all raved about the restaurants and walking along the beach at the end of the day," Ms Cooke said.

Christine and Peter Webb finished fifth on Saturday in the swiss pairs, making a comeback from a 28 out of 30 ranking early in the day.

"We don't know how it happened," Ms Webb said. "It's a mind game, it requires memory. It is the sort of game you will never stop learning."

The event started as a single-day event at the Archie Graham Community Centre and has occurred annually for at least a decade.
