“Tic-tac-toe” or “Three in a Row” is a classic, simple game for two people.

One player places a cross in the grid (“x”). The other player places a circle (“o”) in the grid.

Whoever forms a row first (3 identical characters next to each other, also diagonally) wins.

 

Games on three-in-a-row boards can be traced back to ancient Egypt (around 1300 BC), where such boards were found on roof tiles.
