Here are some things, which I want to implement in due course of time!
Let user choose option to who wants X and who wants 0.- Make it two way-game, Computer vs Human and Human vs Human.
Maintain a Leader-Board for all players who have played.- Add more graphics, to enjoy user-interface.
Any such changes if you can make or have any other ideas, please do contribute!
For any queries you may send me an e-mail on shahmishal1998@gmail.com
