TicTacToe (Console)

A simple two-player Tic Tac Toe console application written in C# targeting .NET 10. This project demonstrates a minimal terminal game where two human players share a keyboard, take turns placing X and O marks on a 3x3 board, and the game detects wins and draws.

Features

• Two local human players (same keyboard)
• Prevents placing marks on already occupied squares
• Detects win conditions and ties (draw)
• Colored marks when supported by the console: X = red, O = green
• Simple, readable ASCII board and input prompts

Project structure

• Program.cs — application entry point; sets up and starts the game
• StartMenu.cs — optional ASCII title screen and console setup
• Board.cs — holds the board state, draws the board, validates and places marks, checks for wins/ties
• Player.cs — manages player input, turn switching and the main game loop

Requirements

• .NET 10 SDK
• A console that supports coloring (Windows Terminal, Visual Studio integrated console, or similar)

Build

Open a terminal in the project folder (where TicTacToeGame.csproj is located) and run:

dotnet build

Run

From the project root run:

dotnet run --project TicTacToeGame.csproj

or run the compiled binary from the output directory produced by dotnet build.

How to play

• The game shows a 3x3 board in the console. Players alternate turns.
• Input a number from 1 to 9 to place your mark on the board.
• The UI maps numbers similar to a numpad layout:
  • 7 8 9 — top row (left → right)
  • 4 5 6 — middle row
  • 1 2 3 — bottom row
• If you enter invalid input or choose a filled square, the game asks you to try again.
• The game ends when a player wins or the board is full (tie). The winner (or tie) is printed, then the game exits when a key is pressed.

Customization ideas

• Add an AI opponent for single-player mode.
• Add a scoring system across multiple rounds.
• Improve the UI with a clearer highlight for the last move.
• Add command-line options for different color schemes or rules.
