The D&D Championship Series was a yearly Dungeons & Dragons championship run at Gen Con. Prior to 2008, the event was known as the D&D Open Championship. The Open first ran in 1977.
Teams of players compete to complete and score well in a pre-written, multi-part adventure, with higher-ranking teams advancing to later rounds. Eventually a single winning team is selected based on scores.
The championship was originally handled by the RPGA, a fan organization run by TSR and Wizards of the Coast. The judges were all sanctioned RPGA Dungeon Masters. Prior to the competition, the RPGA created the adventure.
The event has been run by Wizards of the Coast since 2016 with an adjusted format.
From 2008–13, the championship used the 4th edition Dungeons & Dragons rules. Fifth edition was used for the 2016 Open.
