Everyone stands in a circle, and puts one hand in, either clenched as a fist or open. They take turns, going clockwise around the circle. On a players turn, they count "one, two, three" (doing the hand bobbing thing, most likely) and then 2 things happen simultaneously:

If the player successfully names the number of fingers in the circle (so the number of open hands times five), then they are out, and play continues without them. The last player left in loses.

In subsequent games, the loser will normally start. There is a small ritual for starting the game - the player bumps the top of their fist on the other players fists, counting up as they do so.
