The Machine That Only Played Nim

A computer built for a festival could play exactly one game. The committee related to it deeply.

What happened

In solidarity with a machine in London that could only play Nim, every part of the festival was a game of Nim. Dinner was Nim, played with Knödel. The raffle was Nim. The speeches were replaced by Nim. The committee lost every game to a nine-year-old from Favoriten, who has been undefeated at Slopfest ever since.

Elsewhere in 1951

Ferranti's Nimrod, a computer built only to play the game of Nim, is shown at the Festival of Britain.
