X vs O is a free puzzle game developed by Yury Grebenyuk for Android 9.0. The game is based on the classic "bearded" game that we all have played at least once in our lifetime. The game has a simple yet appealing design, and it features a computer that you can play against.

The game's objective is to align three Xs or Os horizontally, vertically, or diagonally on a 3x3 grid. The game has two modes: single-player and two-player modes. In the single-player mode, you play against the computer, and in the two-player mode, you can play with a friend. X vs O is an excellent game to pass the time and lift your mood.
