To fill a box in with an X press the number key it recommends in the top left corner. If you press a number the scratch cat will fill in another one. The 9 key and the 6 key change the same block so if you click one after another the 4 boxes wont change. If you or Mr. Scratch Cat get three in a row or if you just fill all the blocks in press space. It will then show 3 options: "I won!" "You won!" "We tied!" Press I for "I won!", y for "You won!", and w for "We tied!" Got it? Go beat Mr. Scratch Cat. He is very good at this game!
