LCHNB-PRO

This is a scoring software designed specifically for tennis, which follows the rules of tennis scoring.
The scoring rules for tennis are divided into three levels: 'Set', 'Game', and 'Score'.
Score: The first point is scored at 15, the second point is scored at 30, and the following is scored at 40.
Game: Whoever scored 40 first, the number of games will increase by 1.
Set: When one side wins 6 games first, it is considered as winning 1 set. When both sides win 5 games each, one side wins another game, which is 6:5, to win a set. When both sides win 6 sets, a tie break is required to determine the winner.
