This is a small and nice gadget that will let you enjoy on your desktop a Tic-tac-toe game against your PC.
Tic-tac-toe is a game for two players, X and O, who take turns marking the spaces in a 3×3 grid. The X player usually goes first. The player who succeeds in placing three respective marks in a horizontal, vertical, or diagonal row wins the game. The friendliness of tic-tac-toe games makes them ideal as a pedagogical tool for teaching the concepts of good sportsmanship and the branch of artificial intelligence that deals with the searching of game trees.
An early variant of Tic-tac-toe was played in Roman Empire, around the first century BC. It was called Terni Lapilli and instead of having any number of pieces, each player only had three, thus they had to move them around to empty spaces to keep playing. The game’s grid markings have been found chalked all over Rome.
The game has a number of alternative English names.
Tick-tack-toe, tic-tac-toe, tick-tat-toe, or tit-tat-toe (USA, Canada)
Noughts and crosses or Naughts and crosses (Great Britain, Republic of Ireland, Australia, New Zealand, South Africa)
Exy-Ozys, Xsie-Osies (verbal name only) (Northern Ireland)
X’s and O’s (Egypt, Republic of Ireland, Canada, Scotland, Zimbabwe, India)
In the United States, the name “noughts and crosses” is not well understood, as the word “nought” is archaic in usage, and where X-shaped objects are not generally called crosses except in the case of specific named crosses like St. Patrick’s Cross.
