Two or more players (probably no more than six, but who knows?), in a crowd-full of players, or not necessarily.
Players face each other. Each player has one hand up, fingers extended. Players take turns (more or less) pointing at each other. As soon as you’ve been pointed at, you lose a finger, fingeratively speaking, and put that finger down. The last player with a finger sill standing is considered the “last player standing.”
I know. It doesn’t seem like much. But you’ll be delighted and amused by the intensity of play as the game evolves.
Another fun, provocative, and very short game for as many people as want to play it.
Eric Zimmerman taught this game at Indiecade during his talk “Being a Game Designer: Principles for a Thoughtful Practice“
