Tic-Tac-Toe Game using C# and .NET Framework

Overview

This is a simple Tic-Tac-Toe game developed using C# and the .NET Framework, utilizing Windows Forms to create an intuitive graphical user interface (GUI). The game allows two players to take turns playing as "X" and "O" on a 3x3 grid. The game handles win conditions, draws, and keeps track of player scores. Additionally, it provides options to restart the game or start a new match from scratch.

Features

• Player Turn Display: The current player's turn is displayed to guide users as they take turns.
• Win and Draw Detection: The game automatically checks for win conditions (three identical marks in a row, column, or diagonal) and displays the result. If all nine squares are filled without a winner, it announces a draw.
• Scoreboard: The game keeps track of the number of wins for each player (X and O) and the number of draws.
• Restart Game Option: A "Restart" button allows players to reset the board and continue playing while keeping the scores intact.
• New Game Option: A "New Game" button resets the board and also clears the score, offering a fresh start for both players.
• Button-based GUI: The game board is a 3x3 grid of clickable buttons, where each button represents a cell.
• Responsive UI: Buttons change color when selected, indicating the active player. Winning cells are highlighted in green.

Game Mechanics

The game board is made up of nine buttons arranged in a 3x3 grid. Each button can be clicked to place either an "X" or an "O", depending on the player's turn. The player switches after each move, and the game automatically checks for a win or draw after each turn.

Win Detection

The game checks for eight possible winning combinations:

1. Three in a row horizontally (Rows 1, 2, or 3).
2. Three in a row vertically (Columns 1, 2, or 3).
3. Three in a diagonal (either top-left to bottom-right or top-right to bottom-left).

If a player wins, the winning buttons are highlighted in green, and the scoreboard is updated accordingly.

Draw Detection

If all nine buttons are pressed without a winner, the game announces a draw and increments the draw count on the scoreboard.
