Two players take it in turns to say the word potato, until one of you feels it is the right time to say Birdseye. Whoever says Birdseye first is the winner, unless you say Birdseye at the wrong time, in which case you are the loser. There is no rule on when you can say Birdseye, you can say it on the first go, or wait until the 10th round. It is 100% vibe based. You know when it's right, and you know when it's wrong.
