On each half-hour episode, three children or teenagers (blue, red, and purple) compete against each other in four events that are based on "extreme" versions of skills in popular sports, such as basketball, baseball, football, and soccer. While most of these events include the use of an elastic harness, others make use of a wave pool, and sometimes a racing track is used. During the show's run, more creative and ambitious events were developed, even including a fabricated ski slope.
