In an evenly matched Go game, there's something you can do to determine who gets first move, called nigiri. Like the sushi!

One player takes a handful of white stones, the other guesses whether it's an odd or even number by showing either 1 or 2 black stones.

I enjoy it because the white stones are like the rice you'd use to make nigirizushi. But 'nigiri' just means squeeze or grasp
