The double-loss elimination system is generally divided into two groups, the winner group and the loser group. After the first round of competition, the winner belongs to the winner group and the loser belongs to the loser group to continue the competition. After each round, the losers in the loser group will be eliminated; The situation of the winner group is similar, except that the loser is only eliminated from the winner group and becomes a loser group. After failing again in the loser group (that is, there are always two failures), he will be eliminated from the whole game.
Similar to the common single-loss elimination system, the common double-loss elimination system also has 2-power contestants (for example, 4,8, 16) to ensure an even number of contestants in each round.
