Welcome to the Tic-Tac-Toe Game

Introduction

Tic Tac Toe is a classic two-player game where players alternate marking spaces in a 3x3 grid. The objective is to place three of your marks (either "X" or "O") in a horizontal, vertical, or diagonal row before your opponent does.

Features

• Two-player Mode: Players can take turns to play as "X" or "O."
• AI Mode: Play against a computer opponent, with the AI making moves based on predefined logic.
• Win Detection: The game automatically checks for a winner after each move, detecting horizontal, vertical, and diagonal winning conditions.
• Tie Detection: If all spaces on the board are filled and no player has won, the game ends in a tie.
• Reset Option: The game provides an option to reset the board and start a new game.
• Intuitive User Interface: The game is easy to play with simple click/tap interactions.

Game Rules

• Players alternate turns.
• Player 1 is assigned "X" and Player 2 is assigned "O."
• A player wins by getting three of their marks in a row (either horizontally, vertically, or diagonally).
• The game ends in a tie if the board is full and no player has won.
• After a win or tie, the game will prompt players to restart after clicking the window.

Gameplay

1. Starting a Game:

• Upon launching the game, the player needs to select the mode: 2-player mode or Vs. Computer (if they want to play with AI). After this, the 3x3 grid will be displayed.

2. Making a Move:

• Players click on an empty cell to place their mark (either "X" or "O").
• The game will check if the move results in a win or tie.

3. Winning the Game:

• The game will check if any player has succeeded in getting three marks in a row after each move.
• If a player wins, the game will display a message announcing the winner.

4. Tie Game:

• If all cells are filled and no player has won, the game will announce a tie.

5. Restarting the Game:

Technical Details

Game Logic

The game checks for a win or tie after every move by:

• Checking all rows, columns, and diagonals for three identical marks.
• If a player places their mark in a winning position, the game ends and declares the winner.
• If all cells are filled without a winner, the game ends in a tie.

User Interface (UI)

• 3x3 Grid: The board consists of 9 cells, with each cell initially empty.
• Buttons: Players can click on any empty cell to place their mark.
• Messages: After each game, the UI displays whether the game was won or tied.
• Responsive Layout: The game layout dynamically adjusts based on the screen size, ensuring optimal playability on any device.

Technologies Used

• HTML: Contains the structure of the game, including the 3x3 grid container where JavaScript dynamically generates the grid.
• CSS: Defines the layout and appearance, including the responsive design rules for different screen sizes.
• JavaScript: Contains the logic for dynamically creating the game board, player moves, AI behavior, win/tie detection, and restarting the game.
