In this extended, graphically rich version of the classic Tic-Tac-Toe game you play against a virtual opponent with lightening fast reaction speed. This fully featured game gives you multiple levels and playing options. Blow up the grid size up to a massive 12X12! With two game modes you can also try the challenge of non-square grids. Try to fill your X's or O's in any row, column, or diagonal line, it's all fair game.
