Well, of cos it is a very big task to do.

Even a 4x4x4x4 Four Level Cube program is already hard to write!

But the most difficult part is to find the best way!!

For a simple 3x3 TT game, the program also trace out the exceptional case to prevent lose!!

X                     
    O                
        X

For above case, if program find the most block position to put(i.e. Corner), it will cause quick lose!!
