OXO

OXO is a tic-tac-toe game that used one of the two displays of the EDSAC computer to display the game rather than the contents of the memory as was its purpose. The player would play against the computer which would play a "perfect" game. Input was given using a rotary telephone controller after which the screen was updated and the computer would take its turn.
