Tic Tac Toe os Android

The app is designed for Android mobile devices and after launching it displays an unpretentious relaxing game, similar to a game of paintball, but played only on a desktop with 9 fields.
Instructions for use:
After opening the application, click on the START button. It starts the computer and we try to prevent it from creating a line consisting of 3 identical stones (circles or crosses).
The aim of the game is to create a row of 3 stones next to each other either vertically, horizontally or in diagonals.
