# About Tic-Tac-Toe Master

Tic-Tac-Toe Master is a delightful digital version of the universally loved classic game. Designed for two players, 'X' and 'O', this game invites you to take turns marking spaces on a 3x3 grid. The first player to align three of their marks horizontally, vertically, or diagonally wins the round. This implementation is built purely with HTML, CSS, and JavaScript, ensuring it runs smoothly in any modern web browser without needing any plugins.

The game boasts a clean, responsive design that adapts beautifully to any screen size, whether you're playing on a desktop computer, tablet, or smartphone. With clear visual distinctions between Player X (red) and Player O (blue), intuitive gameplay, and immediate feedback on game status, Tic-Tac-Toe Master offers a polished and enjoyable experience for quick mental challenges.

## How to Play

The rules are simple and true to the original Tic-Tac-Toe:

1.  The game is played on a 3x3 grid.
2.  Player 'X' always starts the game.
3.  Players take turns clicking or tapping an empty cell to place their respective mark ('X' or 'O').
4.  The objective is to be the first to get three of your marks in a row – this can be horizontally, vertically, or diagonally.
5.  If all nine cells on the grid are filled and no player has achieved three in a row, the game results in a draw.
6.  To start a new game at any point, simply click or tap the "Restart Game" button. The status display will guide you, indicating whose turn it is or the outcome of the game.

## Features

- **Classic Gameplay**: Experience the timeless strategy of Tic-Tac-Toe in a modern digital format.
- **Responsive Design**: The game interface dynamically adjusts to fit your screen perfectly, providing an optimal experience on desktops, tablets, and mobile phones.
- **Clear Visual Feedback**: Player marks (X and O) are distinctly colored, and the winning line is highlighted for easy recognition of a win.
- **Interactive Status Display**: Stay informed with real-time updates on whose turn it is ("Player X's Turn" or "Player O's Turn") and game outcomes ("Player X Wins!", "Player O Wins!", or "It's a Draw!").
- **One-Click Restart**: A convenient "Restart Game" button allows players to quickly start a new match.
- **Touch and Mouse Controls**: Seamlessly play using either mouse clicks on a computer or touch gestures on mobile devices.

## Controls

- **Making a Move**: Click (on desktop) or tap (on mobile) on an empty cell within the 3x3 grid to place your mark (X or O).
- **Restarting the Game**: Click (on desktop) or tap (on mobile) the "Restart Game" button located below the game board.

## Tips & Strategies

- **Occupy the Center**: If it's available, taking the center square is generally a strong opening move as it offers more potential winning lines.
- **Block Opponent's Wins**: Always pay attention to your opponent's moves. If they have two marks in a row, your immediate priority should be to block their potential win.
- **Create Forks (Two-Way Threats)**: Try to set up a situation where you have two possible ways to win on your next move. This forces your opponent to block one, allowing you to win on the other.
- **Corner Control**: After the center, corner cells are strategically more valuable than edge (side, non-corner) cells.
- **Think Ahead**: Anticipate your opponent's moves and plan your strategy a few steps in advance.
