1 and 30 players will draw lots to decide the order of appearance.
In the 1. competition, first, players with numbers 1 and No.2 are selected by lottery to enter the competition first, and then one player is added every 90 seconds.
3. If a player is knocked out of the ring from the upper rope after entering the ring, and both feet touch the ground under the ring, then the player is eliminated, and being thrown out of the ring from the middle rope or the lower rope is not eliminated.
When all 30 players come out, the only survivor left in the ring is the winner of this 30-player war.
