Indeed, this is becoming quite common. Bochurim need a healthy outlet since they are in yeshivah and not using social media, going out to entertainment, etc. (boruch Hashem).
These are obviously only meant to be used during breaks bein hasdorim, so the more studious bochurim can stay and learn, while the more restless bochurim can play.
This is especially useful in the winter when it’s hard to play outside, since most yeshiva lack an indoor gym (game room is a cheaper alternative).
