tic tac toe (zero katas)

This is simplest light weight tic-tac-toe application, just open up and quickly start playing with your friends. No need of filling any player names or waiting for screen to load. Ideal for playing during long train journeys or when are you waiting for your order in restaurants. I personally like this game since childhood, even though their are multiple apps for the same but I wanted something even more simpler and fast. Tic-Tac-Toe simplest
