i was wondering if somebody could help me, whenever i try to play multiplayer it always says failed to connect to then some numbers. i am confused why it doesnt let me play cause when i'm at friends houses i can play there with my account.

Download the latest version of toribash that should fix it

Check if your firewall is blocking it.

i have the latest version and i dont have a firewall

are you behind a router?

There's a thread about this in the Game FAQ:
