Tic-tac-toe originated from the ancient Roman Empire around the first century BCE, and it was called Terni Lapilli. The rules of the game differs as each player only had three pieces, moving around the empty spaces to keep playing. First print reference of the game appears in Britain with the name "Noughts and Crosses" in 1864. The name "tic-tac-toe" is renamed from "Noughts and Crosses" in the 20th century USA.
Tic-tac-toe is a two player game that takes turn marking spaces on a 3 by 3 grid, and the objective of the game is to place three connecting marks in a horizontal, vertical, or diagonal row.
Although Tic-tac-toe appear simplistic to play, it contains 138 terminal board positions and 255,168 possible ways these terminal board positions are obtained.
Tic-tac-toe is one of the first games to be played by children due to its fast setup and easy engagement.
The first strategy game on a computer was OXO, a version of Noughts and Crosses (known in the US as Tic-Tac-Toe), which was recreated on the EDSAC (Electronic Delay Storage Automatic Calculator) by Alexander S. Douglas of the USA in 1952.OXO was ground breaking in a number of ways, as it was also the first video game and the first multiplayer game.
