• 16-player single-elimination bracket
• Matches consist of three segments: 90 minutes of 5+1, 60 minutes of 3+1, and 30 minutes of 1+1.
• The player with the most cumulative points at the end of the match wins.
• Games that start before the time for a segment runs out count toward the final score.
• Players can resign from the match within the last 10 minutes of the 1+1 segment, with the player's win percentage being capped at 35%.
• In case of equal number of points – tiebreaks:
• A four-game 1+1 match.
• A single bidding armageddon game with a base time of 5 minutes.

The tournament starts on January 1 and, depending on the number of participants, consists of 4 or 5 rounds.{{efn|Since 2020, due to the steadily growing number of players, a 5-round format is necessary.}} All players are divided into groups (up to 12 people{{Efn|If the number of all players in a given round is not divisible by 12, smaller groups are created. In case all groups cannot be of the same size, players with the highest rankings go to smaller groups.}}), and only the winners advance to the next round.{{Efn|In case of equal points, all winners in the group advance.}} Players play in each round a maximum of 22 games simultaneously (with each opponent as White and Black), with a maximum of one day allocated for each move. So it can be considered a form of correspondence chess. The winner of the Championship is the player who accumulates the most points in the final round.
