0 a competition in the sport of curling (= a game played on ice in which special flat, round stones are slid towards a mark):
I organized bonspiels for the school kids to be played on outdoor sheets of ice with jam pails full of frozen sand for rocks.
In my short curling career, I've competed in several bonspiels (tournaments) and become a certified instructor.
We were always having bonspiels and everybody won something.
Although I had never met him I knew he had played in several bonspiels in the club.
