Rules. The initial ranking of players on the ladder is based on their current points. A player may challenge any other player above his or her position who is within a range of 5. Players may issue or accept more than one challenge at a time. Players are not required to accept more than 1 challenge per week but can accept as many as they want.
However, members must accept valid challenges from other players, or accept a loss by default. Players are not required to accept a challenge from another player they have defeated within the past two weeks. Member will be deducted 100 points if he or she doesn't play any match in 30 days unless there's a valid reason. The standard match format for the ladder is 1 tie-break set
However, players can agree on any match format based on the condition. If players can't come to an agreement then they must use the standard format.
After each match, the winning player will take points from the opponent. The number of points that the winner takes is calculated based on the winner's current points, opponent's points and the importance of the match. If enough number of matches are played, the best players will be at the top of the ladder. Any match format can be used.
