Tic tac toe, also known as noughts and crosses or in some countries, the game has roots going back to ancient Egypt! Ancient Egyptians enjoyed playing a similar game of tic-tac-toe, with boards found from as early as 1300 BCE. The ancient Romans played a similar game called "terni lapilli", though simpler than today's game, it already showed humanity's innate need to form three things in a row.
By the 19th century, the game we know and love as tic tac toe become popular across Europe and America. The game became a family staple with parents, grandparents and kids playing together, and that's when it was discovered just how much of a game theory bonanza it is. The British started using "noughts and crosses" in 1850s, and in USA the name "tic tac toe" caught on by the early 1900s.
In the middle of computer revolution, tic tac toe was one of the first games to be digitized. In fact, OXO was one of the first video games ever created (1952) - a version of tic tac toe programmed for the EDSAC computer by Alexander S. Douglas. WarGames (1983): One of the first movies to depict AI and game theory was a movie about a kid who accidentally engaged in a game of global thermonuclear war while playing tic tac toe with a computer.
The internet years brought the game back into peoples lives in new and exciting ways. The web took over as the way to play tic tac toe, for people in different cities or countries to play, or just for players to get some practice in quickly. Our version builds on this tradition, with an elegant UI, responsive animations, and intelligent AI so you enjoy it even more.
Select X or O. Traditionally, X moves first and gains early control.
Players alternate placing their symbol in an empty square.
Align three symbols horizontally, vertically, or diagonally.
If all nine squares are filled without alignment, the game ends in a draw.
Modern adaptations expand the traditional format to increase depth and strategic complexity.
From a game theory perspective, tic tac toe is a "solved" game. When both players play perfectly, the game will always end in a draw. This means that if you know the right moves to make and your opponent knows them too (or if you're playing against our Hard AI), neither player can force a win - the best you can hope for is a draw.
Our Hard mode uses the minimax algorithm, the same algorithm used in game theory to calculate the best move. It explores ALL paths that the game could take on, and chooses the one that results in the best outcome. In tic tac toe, this means it can never lose - at worst, it will draw. If you can get a draw against our Hard AI, congratulations - you've mastered the game of tic tac toe!
