I was playing the Finals Showdown with a friend and we played until we got into a 1v1 Fall Mountain together. We started messing around on the obstacles until the timer ran out, seeing what would happen in a tie...

The answer is you both lose. So lame. How are we going to put the broken pieces of our society together if our games are telling us working together is wrong? So disappoint. #CrownsforSolidarity

This is well known if you time out on fall mountain or lost temple. However if multiple players survive the time limit (unlikely) in jump showdown, hex a gone or roll off everyone will get a crown.
