This simple way to avoid this problem is to avoid using the style
property to store your game state. A cleaner way would be to keep a
separate JavaScript array to store the state of the 9 cells. On each
click, you could very easily run through this array and update the
style on the table cell using classes to assign the X or O background
image.
