How do I get closer to my brother?

Anyone with brothers please send advice! So I am a college student with 2 brothers and a sister. I am close with my sister, but not as much with my brothers. We talk and we laugh but I feel like I don’t see or talk to them much because most of the time if they’re not at school, they’re sleeping or playing games in their room. They rarely go out of their rooms, and don’t really spend time with anyone or leave their rooms unless my parent request we all hang out/come out our rooms for something

It’s not like we live in a bad home or have a bad relationship, my house is very chill and fun. I just have a hard time sometimes trying to connect with them. I do talk to my older brother about movies and such a little bit, but I don’t really get too see my younger brother as much. How do you become closer to your brothers? Are there any small ways to get closer in a subtle way?

I don’t want to just randomly go up to him and act like we are buddy buddy tell each other everything besties close, but find subtle little ways to get closer over time.
