Nomic is an initially boring finite game created in 1982 by the
philosopher Peter Suber.
On your turn you roll a die and add its value to your score. The
first person to reach 100 wins and the game ends. However, each player can also propose a new rule or a modification of an old one on their turn and if the rule is adopted then the game can morph into
something else.
Bob: "
Let's play Nomic."
Carol: "Great. I propose the first rule is that we change the name to NotNomic and replace the number 100 in the win state with Infinity. That way we have an infinite game we can enjoy playing forever."
Bob, Carol, Ted, Alice: "Aye."
Ted: "The ayes have it. The rule is adopted. I propose we change the name to NullNomic and change the number in the win state to zero so
the game is over before it starts and we don't have to play at all."
Bob, Carol, Ted, Alice: "Aye."
Alice: "The Ayes have it. Boy am I glad that
shenanigans is over. Anyone up for a beer?"
