OX Game

The main goal of this game is to fill the entire board with O's. But as you try and do that there are certain patterns that change O's into X's and X's into O's. There are three game modes: 3x3, 4x4, 5x5. Start with 3x3 and as u get better progress through the other game modes for a harder challenge. 3x3 is fairly easy, 4x4 is really hard and 5x5 is like hell.
