Update of competition rules: I want to make this competition into a long-term competition. The address of the new annual competition is unnecessary and will be deleted. The original competition address will still be used. In future competitions, the total ranking will always be used for grouping, and the lowest score is 0, This will be more beneficial to new players. Each round of competition will take the form of invitation. Players who want to continue the competition need to confirm to continue the competition, which will be convenient for players who do not want to continue the competition. There will be no fixed start time for the competition. After each round of competition is completed, there will be about two weeks to invite players to participate in the new round of competition. New players can apply to join in these two weeks. The winner and runner-up of the total points will be rewarded for every 12 rounds of competition. The winner will get the championship ring and $100, and the runner-up will get $100 (only those who participate in at least 9 rounds of competition will be eligible for rewards, in order to avoid the original players with higher points from not participating in the competition to get rewards). Other rules are the same as the original rules.
