Sports Rules and Tournaments

According to kho kho rules, when an active chaser turns their shoulder line more than 90 degrees from their original direction of movement, it constitutes a foul. This prevents unfair movement and maintains the directional integrity of the chase.

Kho kho is a team sport that builds multiple positive qualities. Obedience to rules, loyalty to teammates, discipline in following protocols, sportsmanship in competition, and teamwork are all core values developed through playing kho kho.

In American football, the offensive team must gain at least 10 yards in 4 attempts (called downs) to earn a new set of downs. If they fail to gain 10 yards after 3 downs, they typically punt on 4th down to avoid giving the ball to the opponent in good field position.

The line of scrimmage is the imaginary transverse line where the ball is placed at the start of each play. Offensive and defensive players must position themselves on or behind their respective sides of this line until the ball is snapped.
