Introduction

Hello, fellow developers! I'm excited to share my latest project: a classic Tic-Tac-Toe Game. This project is a great way to practice your JavaScript skills, particularly in handling game logic, DOM manipulation, and user interactions. Whether you're just getting started with JavaScript or looking for a fun challenge, this Tic-Tac-Toe game is perfect for honing your skills.

Project Overview

The Tic-Tac-Toe Game is a web-based implementation of the popular two-player game. The project showcases how to create interactive elements, manage game state, and implement simple AI logic. The game is designed to be fully responsive, making it playable on both desktop and mobile devices.

Features

  • Two-Player Mode: Play with a friend on the same device.

  • Game Logic: Automatically checks for a winner or a draw after each move.

  • Reset Functionality: Easily restart the game at any point.

  • Responsive Design: The game layout adapts to different screen sizes, providing a consistent experience on all devices.

Technologies Used

  • HTML: Structures the game interface.

  • CSS: Styles the game board, buttons, and other UI elements.

  • JavaScript: Manages the game logic, including player turns, win conditions, and resetting the game.

Project Structure

Here's a quick look at the project structure:

Tic-Tac-Toe/
├── index.html
├── styles.css
└── script.js

  • index.html: Contains the HTML structure of the Tic-Tac-Toe game.

  • styles.css: Includes CSS styles for the game board and responsive design.

  • script.js: Handles the game logic, including player turns and win conditions.

Installation

To get started with the project, follow these steps:

  1. Clone the repository:

     git clone https://github.com/abhishekgurjar-in/Tic-Tac-Toe.git

  2. Open the project directory:

     cd Tic-Tac-Toe

  3. Run the project:

    • Open the index.html file in a web browser to start playing the Tic-Tac-Toe game.

Usage

  1. Open the website in a web browser.

  2. Start the game by clicking on any empty cell in the grid.

  3. Take turns to place your marks (X or O) in the cells.

  4. Check the result: The game will declare a winner if there’s a winning combination or a draw if all cells are filled.

  5. Reset the game: Click the "Reset Game" button to start a new game.

Code Explanation

HTML

The index.html file sets up the structure of the Tic-Tac-Toe game, including the game board and control buttons. Here’s a snippet:

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Tic-Tac-Toe Game</title>
    <link rel="stylesheet" href="style.css" />
    <script src="script.js" defer></script>
  </head>
  <body>
    <div class="msg-container hide">
      <p id="msg">Winner</p>
      <button id="new-btn">New Game</button>
    </div>
    <main>
      <h1>Tic Tac Toe</h1>
      <div class="container">
        <div class="game">
          <button class="box"></button>
          <button class="box"></button>
          <button class="box"></button>
          <button class="box"></button>
          <button class="box"></button>
          <button class="box"></button>
          <button class="box"></button>
          <button class="box"></button>
          <button class="box"></button>
        </div>
      </div>
      <button id="reset-btn">Reset Game</button>
    </main>
    <div class="footer">
      <p>Made with ❤️ by Abhishek Gurjar</p>
    </div>
  </body>
</html>

CSS

The styles.css file styles the Tic-Tac-Toe game, including the grid layout, buttons, and responsive design. Here are some key styles:

* {
    margin: 0;
    padding: 0;
  }

  body {
    background-color: #548687;
    text-align: center;
  }

  .container {
    height: 70vh;
    display: flex;

    justify-content: center;
    align-items: center;
  }

  .game {
    height: 60vmin;
    width: 60vmin;
    display: flex;
    flex-wrap: wrap;
    justify-content: center;
    align-items: center;
    gap: 1.5vmin;
  }

  .box {
    height: 18vmin;
    width: 18vmin;
    border-radius: 1rem;
    border: none;
    box-shadow: 0 0 1rem rgba(0, 0, 0, 0.3);
    font-size: 8vmin;
    color: #b0413e;
    background-color: #ffffc7;
  }

  #reset-btn {
    padding: 1rem;
    font-size: 1.25rem;
    background-color: #191913;
    color: #fff;
    border-radius: 1rem;
    border: none;
  }

  #new-btn {
    padding: 1rem;
    font-size: 1.25rem;
    background-color: #191913;
    color: #fff;
    border-radius: 1rem;
    border: none;
  }

  #msg {
    color: #ffffc7;
    font-size: 5vmin;
  }

  .msg-container {
    height: 100vmin;
    display: flex;
    justify-content: center;
    align-items: center;
    flex-direction: column;
    gap: 4rem;
  }

  .hide {
    display: none;
  }
.footer {
  margin: 50px;
  text-align: center;
  color: white;
}

JavaScript

The script.js file manages the game logic, including handling player turns, checking for a winner, and resetting the game. Here’s a snippet:

let boxes = document.querySelectorAll(".box");
let resetBtn = document.querySelector("#reset-btn");
let newGameBtn = document.querySelector("#new-btn");
let msgContainer = document.querySelector(".msg-container");
let msg = document.querySelector("#msg");

let turnO = true; //playerX, playerO
let count = 0; //To Track Draw

const winPatterns = [
  [0, 1, 2],
  [0, 3, 6],
  [0, 4, 8],
  [1, 4, 7],
  [2, 5, 8],
  [2, 4, 6],
  [3, 4, 5],
  [6, 7, 8],
];

const resetGame = () => {
  turnO = true;
  count = 0;
  enableBoxes();
  msgContainer.classList.add("hide");
};

boxes.forEach((box) => {
  box.addEventListener("click", () => {
    if (turnO) {
      //playerO
      box.innerText = "O";
      turnO = false;
    } else {
      //playerX
      box.innerText = "X";
      turnO = true;
    }
    box.disabled = true;
    count++;

    let isWinner = checkWinner();

    if (count === 9 && !isWinner) {
      gameDraw();
    }
  });
});

const gameDraw = () => {
  msg.innerText = `Game was a Draw.`;
  msgContainer.classList.remove("hide");
  disableBoxes();
};

const disableBoxes = () => {
  for (let box of boxes) {
    box.disabled = true;
  }
};

const enableBoxes = () => {
  for (let box of boxes) {
    box.disabled = false;
    box.innerText = "";
  }
};

const showWinner = (winner) => {
  msg.innerText = `Congratulations, Winner is ${winner}`;
  msgContainer.classList.remove("hide");
  disableBoxes();
};

const checkWinner = () => {
  for (let pattern of winPatterns) {
    let pos1Val = boxes[pattern[0]].innerText;
    let pos2Val = boxes[pattern[1]].innerText;
    let pos3Val = boxes[pattern[2]].innerText;

    if (pos1Val != "" && pos2Val != "" && pos3Val != "") {
      if (pos1Val === pos2Val && pos2Val === pos3Val) {
        showWinner(pos1Val);
        return true;
      }
    }
  }
};

newGameBtn.addEventListener("click", resetGame);
resetBtn.addEventListener("click", resetGame);
