Complete Tennis Rules Guide: Advantage Sets, Hawk-Eye Challenges and 2026 Rule Changes Explained

The four Grand Slams attract billions of global viewers annually. This guide is based on 2026 ITF, ATP, and WTA rules, systematically covering all core knowledge for tennis viewers.

1. Basic Match Structure

Tennis uses a three-tier scoring system: Point, Game, and Set.

Games are scored: Love, 15, 30, 40, Game. When the score reaches 40-40, it's called Deuce, and a player must win two consecutive points to win that game.

2. Advantage Sets and Tiebreaks

Advantage Set: When the score reaches 6-6, play continues until one player leads by two games.

Tiebreak: When the score reaches 6-6, a tiebreak is played. The first player to reach 7 points with a lead of 2 or more wins the set.

3. Service Rules

Serves must be made from behind the baseline. Two failed serves result in a Double Fault, awarding the point to the receiver.

4. Hawk-Eye Challenge System

Hawk-Eye uses high-speed cameras to track ball trajectory with precision within 3 millimeters. Each player receives three challenges per set.
