An ACBL club sanction grants the right to an entity to conduct bridge games at regularly scheduled times and locations and award masterpoints at those games in accordance with specific ACBL rules and regulations.

There are approximately 3,200 clubs that conduct ACBL sanctioned games. Some operate only a monthly game, while others operate as many as 21 games a week. Altogether, over 3 million tables of sanctioned games in clubs are played annually throughout ACBL territory.

Games must be conducted in accordance with both the letter and the spirit of ACBL regulations as well as the “Laws of Duplicate Bridge.” The success or failure of games conducted by a club is the responsibility of the club manager. The club manager is free to operate the club as he or she sees fit, as long as the operation of ACBL sanctioned games falls within the limits prescribed by ACBL.
