In an international judo match, the scoring system is based on how effectively a competitor throws their opponent or controls them on the ground. The two primary scores are Ippon, which earns a full point and results in an immediate win, and waza-ari, which is a half-point. Accumulating two waza-ari scores also results in a win. Other scores include yuko, which carries less weight than waza-ari. The match ends when a player achieves Ippon or when time expires, with the competitor having the highest score winning.
