3

A row, column or diagonal has three squares. For simplicity, let's just talk about columns. During a game, a square can contain a cross, a nought or a blank. This means there are 3 x 3 x 3 = 27 column possibilities. But many of these are really the same. For example, X X O is the same as X O X. In fact, there are just TEN possibilities - can you find them all?

1	2	3	4	5	6	7	8	9	10

Click any of the three squares to change it from blank to nought to cross and to blank again.
