[07/03, 5:50 pm] Adil Khan: Is tennis only sport to have double serve
[07/03, 5:50 pm] Meta AI: Tennis is unique in having a "double fault" rule, where a player has two chances to make a valid serve. If they fail to make a valid serve twice in a row, it's considered a "double fault" and the opponent wins the point.
However, other sports have similar concepts:
1. Volleyball: A player has two chances to make a valid serve. If they fail twice, the opposing team gains possession.
2. Badminton: A player has two chances to make a valid serve. If they fail twice, the opposing player scores a point.
While these sports have similar rules, tennis is distinct in its "double fault" terminology and the specific rules surrounding serving.
