15 people want to play hide-and-seek, and 9 people come, which means that 9 people have been caught, so 15-9=6, so there are still 6 people left to find.

game rule

First, select a range. After guessing boxing or certain rules, choose one person to blindfold or count behind everyone's back, which can be long or short. Others must find a place to hide during this time. Then that person will find someone else, and the person who finds it first is the person who looks for it in the next round.

Those who have not been discovered and finally returned to the starting point and have not been discovered by the explorer will not participate in the second game of guessing boxing and directly become hidden people. The game can be played repeatedly.
