Yes, kabaddi has several rules and techniques. Some important rules include the raider needing to continuously chant "kabaddi" to prove they are exhaling, and the defenders needing to prevent the raider from returning to their own half. Techniques like dodging, hand touches, and footwork play a crucial role in both offence and defence strategies. Additionally, teams can strategize by coordinating their movements and focusing on weaker defenders to maximize their chances of scoring points.
