I have never seen anything like that, three zeroes to end the game.
I was hoping it would happen when I saw the scores (made sense for everyone to bet it all) and it did!
One of them should have got that question though.
I know it’s happened before a few times but I had never seen it. You tube has a vid from a teen tourney in 2013
