Tic Tac Toe, also known as Noughts and Crosses or XOX, was played in the first century BC in the Roman Empire but may have originated earlier.

This version has been developed alongside our Gomoku board game engine, and has several grid sizes (3x3, 4x4, 5x5 & 6x6) and various difficulty levels to choose from.

While the classic 3x3 grid is very simple, larger grids can pose more of a challenge.
