How can we split rooms in our house for uni fairly without meeting up?

I am starting uni this year and have got a house with three strangers. We all live quite far away from each other and before we move we need to decide what rooms we are having in the house. What is a fair way to do this without having to meet up?How can we split rooms in our house for uni fairly without meeting up?
Talk to them about who gets what room and if they want to leave it to chance you guys can always use an online dice roller and see who gets first pick or just show up there and figure things out.How can we split rooms in our house for uni fairly without meeting up?
The only way is to look at the floor plan of the house and try to come to an agreement via email or phone obviously.
