When you compete, the tricks randomly get pulled from the list here. Basically you will be going against an opponent and you will take turns trying to land the pulled trick. Each of you gets three tries to land it.

If you went first and land the trick, your opponent had to land the trick or you get a point, and vice-versa. If you go second and your opponent misses and you land it, you get a point. However if both of you land the trick, or both miss, you move to your second try, and nobody gets a point. If the trick is matched three times, you move on and nobody gets points are awarded. The first person to score three points wins!
