How do i share data between computers

I'm working on a game that doesn't require you to run around anywhere unlike the other unity 3D games and multiplayer tutorials that I've seen, for my game you simply click the screen as many times as you can in the allocated time. The single player is fully working but i can't figure out how I could connect a game like this up with the unity multiplayer stuff as they only have to access the final score after the time to display either defeat or victory.

How could i share this variable between the computers?
