Kickboxing, as the name suggets, is a sport which combines kicking and boxing. The sport originated in Japan and is now played in various countries of the world.
It is a two-player game where players fight each other with boxing gloves in a ring and use kicks and punches in turn, to overcome the opponent. Unlike in boxing where you get a chance to get up, in this sport once you fall, it's over; you become the loser.
Kickboxing is practiced in different forms in different countries and accordingly has names like Japanese kickboxing, American kickboxing and more. However, it is different from Thai boxing which has some different rules.
