the player they lost to wins their match of the second round. If a player loses to a second round loser, they are eliminated from the tournament. Another variant, called the (third-place) challenge, is used, particularly in scholastic wrestling. The winner of the L bracket may challenge the loser of the finals in the W bracket, if and only if the two contestants had not faced each other previously; if the challenger (the winner of the L bracket) wins, they are awarded second place, and the loser of the W final is dropped to third place. This system is used particularly where the top two places advance to a higher level of competition (example: advancement from a regional tournament to a state tournament). Another is the balanced variant which is a bracket arrangement that is not strictly divided into two brackets based on number of losses. Players with different numbers of losses can play each other in any round. A goal of the variant is that no player sits idle for more than one round consecutively. The added complexity of the brackets is handled by using "if necessary" matches. The flexible approach allows practical bracket designs to be made for any number of competitors including odd numbers (9, 10, 11, 12, 13, etc.). A possible alternative is a single-elimination format where each match is a best-of-5-or-more series. This format still allows a competitor to lose (perhaps multiple times) while still remaining eligible to win the tournament. Of course, having multiple games in each series also requires considerably more games to be conducted. It is also susceptible to bad seeding. Another is the modified single-elimination tournament which guarantees at least two games per competitor, but not necessarily two losses for elimination. The brackets are similar to double-elimination, except the two finalists from the L bracket (each with one loss) face the two finalists from the W bracket (neither with a loss) in a single elimination semi-final and final. The Little League World Series began using a modified double-elimination bracket in 2011. Eight U.S. teams and eight international teams compete in respective double elimination formats until their respective championship games, which are single elimination. That is, irrespective of whether a team has one loss, or no losses, that team would be eliminated with a loss in either the U.S. or international championship game. The two respective champions then play a single elimination
