-
All players must strive to be fair to everyone during a match
-
All players must be obligated to have a referee mindset at all times
-
The ruling of the judge/referee must be followed during a match
-
You must play for your own benefit

STRUCTURE
The tournament will be 10 hanchan of a pure cumulative format, with no top cut. Prizes and rankings will be determined by your total score at the end of all 10 games. For all 10 hanchan, match pairings will be created using a fixed group count pairing system. This means players are ordered by total score after each round and divided into a fixed number of groups to create the pairings for the next round, as seen below.
FOOD AND DRINK
Water and coffee will be offered to players from the start of each tournament. All dark-colored drinks, including coffee, are not allowed in the carpeted Sanctuary room, so please dispose of your drink in advance if you are slated to play there.
The tournament will not be providing lunch, but there are countless eating establishments of various cuisines within a 2 block radius of the venue.
