O`s and X`s .

The game of Nought`s and Crosses . Been around since at least the Roman times. Am told there are a possible 255,168 combinations, wh`ever played on a board or paper.
My theory is whoever goes first can not lose. So put it to the test down at Bonnymead park, in the childrens playground. Nobody else there, so had to play myself. Won all three games. So I must be right.
