3 Player TicTacToe

New invention in TicTacToe. now 3 players can play. Boost up your mind.

Same rules but here the dimensions are different, 4x4 instead of 3x3
Any player getting three marks in line will win

the craze here is that when a player has two marks in line. now he is having two options to win, and the other two players will have to unite together and stop him (one will mark to one side of its completion to stop him and other will to the other side).
Hence it creates a heavy mind taking approach to stop two players form winning and making an approach crisp enough to deceive two players.
I am working to make this approach using GUI also and will upload it soon.
