About The Game

This is a console game built in C#. Two players take turns placing their mark (X or O) on a 3x3 grid. The first player to align three marks in a row, column, or diagonal wins the game. If all cells are filled with no winner, the game ends in a draw.

Features

• Two Game Modes: Play against a friend locally, or challenge the AI
• AI Opponent: The AI randomly selects from available cells each turn
• Input Validation: Handles non-numeric input, out-of-range numbers, and already taken cells
• Play Again: Replay without restarting the program
• Clean Console UI: The board refreshes each turn for a smooth experience

Tech Stack

• C#: Core programming language for all game logic
• Visual Studio / .NET : Used for development and execution

Installation / How to Play
