Jeopardy! Teen Tournament
Leonard Cooper in 2013 is the only contestant in Jeopardy! tournament history (all tournaments combined) to lose his semifinal but win the tournament. A triple-zero score in the second semifinal necessitated the use of the wild card option in the semifinals, similar to the first round. In the third semifinal, Nilai Sarda ($30,400) defeated Cooper ($30,200) and Emily Greenberg ($24,400). The only other non-zero semifinal score was Irene Vazquez ($100) from the first semifinal.  Since then, all Jeopardy! tournament semifinals require a winner.  A triple-zero score will now require a tie-breaker.
