What should roommates do if their addiction to games affects their personal rest?

Everyone has his own hobbies, some like playing games, some like playing badminton, and some like watching plays. We can't say anything about other people's hobbies. After all, that's their own business. But sometimes what they do will affect us, so we should communicate with them in a euphemistic way first.

I have a roommate who was obsessed with playing the glory of the king for a while. She only knows how to play games every day, playing during the day, playing at night and eating. He is free when he plays games during the day. Whenever he plays games at night, the noise of the games is too loud, which disturbs our rest. In this case, we will do so.

First, people in our dormitory will remind her to wear headphones to play games. At first, this method was very useful. As soon as you tell her that we are going to sleep, she will put on her headphones immediately and won't disturb our rest.

Secondly, sometimes I go up to her and show her my watch. After being reminded many times, I turn down the sound. It's late for bed, and she has realized that she can't play any more. It's time for bed.

Third, when she has been addicted to the game for a long time, she won't listen to you anyway, but she has to play the magic weapon. Our head teacher forbids us to play games, and we will be punished if we are found. When she can't stop playing games, as long as she takes out her mobile phone and dials the mobile phone of the class teacher, she will stop playing games immediately.

Fourth, if it really doesn't work, there is a last resort, that is, when she wants to rest, the rest of us turn the volume of our mobile phones to the maximum and deal with her the way she deals with you.
