How to play joint game (we often play it in school), please answer quickly if you know, I am afraid that others will laugh at me and I can’t even play it. I'm too embarrassed to ask them!

First of all, they are divided into two groups, and they all determine the steel hammer. Whoever wins is the boss, followed by the second one, and so on. Then the two groups chase each other. For example, if the boss meets someone with a lower level than the boss, That person can't move, and if he does, he will explode until someone in the group touches him. If someone of the same level touches him, he will be hit with a steel hammer. Whoever loses will be hit, until all the people in the group are hit. , if group A has one more person than group B, the last person in group B will have two lives. (You don’t know how we did the last one!) Hope you adopt it! ! !
