Since Carcassonne is brought into BGA in late 2016, the King of Carcassonne championship series is set up with an initiative to bring in online worldwide Carcassonne tournaments designed for literally everybody, across all time zone, especially those can't go physically to the official World Championship for whatever reason.

After initial trial and error, currently there are 3 tournaments that are running regularly every year, and occasionally other tournaments are held as well.

Out of the 3 tournaments, the first 2 are open to everyone, and thanks to the love of Carcassonne community, they are some of the biggest tournaments in BGA.

1. King of Carcassonne World Championship - Swiss system format that usually starts at Jan

2. King of Carcassonne World Cup - Single Elimination format.
(In 2021 edition, it attracted a record high of 482 players, going close to 512, the upper limit of places available in BGA for tournaments in this format. So, starting from 2022, the Groups Stage format is employed. Using Single Elimination in both stage 1 and 2 to keep the whole tournament in Single Elimination format essentially, the number of participants can theoretically increase to 1,000,000. The tournament also moves from August to July)

The first two tournaments, in their high prestige on their own, also act as qualification to the 3rd and ultimate tournament

3. King of Carcassonne Tournament of Champions - Round Robin format in which the winner is crown the King of Carcassonne of the year!
Currently to qualify for the Tournament of Champions, you must reach the required standard (see below) in one or both tournament(s) in the same year.

Invitation to the Tournament of Champions goes out in three batches, players qualified for standard A get the first invitation to the tournament. It is guaranteed to have enough (or more) space for standard A players at that time. If those players don’t respond by a certain date, or withdraw thereafter, then open seats are offered to the Standard B players, and so on to the Standard C players. Players can register to fill up seats available once the invitation is sent to them.
