Club Challenges are monthly interclub competitions hosted by a different participating club each time. The previous winning club travels to the designated challenger club to compete in an eight-end game.

​

The losing team is eliminated from the challenge for the remainder of the season, while the winning team advances to face the next challenger at their home club. This process continues throughout the season until the final game determines the overall winner.

​

The season champion is the club that wins the final game of the challenge.
