< Playing Rules >
|Time allowance||The time allowance is 10 minutes per side, with overtime of 25 moves every 15 minutes|
|Playing Conditions||All games are played on even, with Black giving a komi of 6.5 points|
|Color||Colors are determined by the system automatically|
< Preliminary Rounds >• Participants play freely at least six games in their Class room during the Preliminary Rounds. Participants are not allowed to play with the same person twice.
• Places will be decided by the following method of calculation. In the Main Class, 32 players (Asia & Oceania 16, Europe & Africa 8, North, Central & South America 8) will win their way through the preliminary rounds, and in the Ranked Classes 16 players (Asia & Oceania 8, Europe & Africa 4, North, Central & South America 4) will do so.
The ranking is determined by points in descending order.
1. Points = W / N + W x 0.02 (W = number of wins, N = number of games played)

Example: you win 4 out of 8 games, you collect 4/8 + 4 * 0.02 = 0.58 points.
2. With tied points, the player with higher number of wins is ranked higher.

4. With tied points, wins, and SOS, the players are ranked equal.
