Ninja Warrior is a head-to-head competition with multiple rounds and triple-elimination each episode. There are no teams, and each child contestant competes for themselves. Contestants are divided into age groups (9+10, 11+12, 13+14). Boys and girls compete with each other without segregation. Five runs in each age group are played to determine the episode’s winner in each age group, for a total of three winners per episode, one per age group. Within each age group, the first two runs are seeding races without risk of elimination. Each run’s winner then faces the other run’s loser, with the two winners then facing each other to determine that episode’s winner in that age group.
