1. Introduction

A card-matching game (also known as a Memory Game) is a simple and fun game where players flip two cards at a time, trying to match pairs. The game is won when all pairs are matched.

In this guide, we’ll build an interactive card-matching game using jQuery, with animations, sounds, and a timer.

2. Setting Up the Environment

Before we start coding, ensure you have:

A code editor (VS Code, Sublime, or Notepad++)
A web browser (Chrome, Firefox, or Edge)
Basic knowledge of HTML, CSS, and JavaScript (jQuery)

We will use:

HTML for structure
CSS for styling
jQuery for interactive behavior

Including jQuery

Make sure to include jQuery in your project. Add this in your <head> section:

<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>

3. HTML Structure

We will create a game board with cards arranged in a grid.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Card Matching Game</title>
    <link rel="stylesheet" href="styles.css">
    <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
    <script defer src="script.js"></script>
</head>
<body>
    <h1>Card Matching Game</h1>
    <p>Match all the cards to win!</p>
    <div id="game-board"></div>
    <button id="restart">Restart Game</button>
</body>
</html>

4. Styling with CSS

The CSS styles the game grid, cards, and animations.

body {
    text-align: center;
    font-family: Arial, sans-serif;
    background-color: #f4f4f4;
}

#game-board {
    display: grid;
    grid-template-columns: repeat(4, 100px);
    grid-gap: 10px;
    justify-content: center;
    margin: 20px auto;
    width: 440px;
}

.card {
    width: 100px;
    height: 140px;
    background-color: #ccc;
    display: flex;
    align-items: center;
    justify-content: center;
    font-size: 2em;
    cursor: pointer;
    border-radius: 10px;
}

.card.flipped {
    background-color: white;
}

.card.matched {
    background-color: lightgreen;
    cursor: default;
}

5. Implementing Game Logic with jQuery

Now, let’s create the logic for:

Flipping cards
Checking matches
Restarting the game

Step 1: Define Variables

$(document).ready(function () {
    const cards = ["🍎", "🍎", "🍌", "🍌", "🍇", "🍇", "🍉", "🍉", "🍊", "🍊", "🍒", "🍒", "🥝", "🥝", "🍍", "🍍"];
    let flippedCards = [];
    let matchedPairs = 0;
    let canFlip = true;

    function shuffle(array) {
        return array.sort(() => 0.5 - Math.random());
    }

    function createBoard() {
        let shuffledCards = shuffle(cards);
        $('#game-board').html('');
        shuffledCards.forEach((emoji, index) => {
            $('#game-board').append(`<div class="card" data-id="${index}" data-emoji="${emoji}"></div>`);
        });
    }

    function resetGame() {
        matchedPairs = 0;
        flippedCards = [];
        canFlip = true;
        createBoard();
    }

    $('#restart').click(resetGame);
    resetGame();
});

Step 2: Handle Card Clicks

$(document).on('click', '.card', function () {
    if (!canFlip || $(this).hasClass('flipped')) return;

    let card = $(this);
    card.text(card.data('emoji')).addClass('flipped');

    flippedCards.push(card);
    if (flippedCards.length === 2) {
        canFlip = false;
        setTimeout(checkMatch, 500);
    }
});

Step 3: Check for a Match

function checkMatch() {
    let [first, second] = flippedCards;
    if (first.data('emoji') === second.data('emoji')) {
        first.add(second).addClass('matched');
        matchedPairs++;
        if (matchedPairs === 8) {
            alert("You won!");
        }
    } else {
        first.add(second).removeClass('flipped').text('');
    }
    flippedCards = [];
    canFlip = true;
}

6. Enhancing the Game with Animations and Sound

Adding Flip Animation

Modify the CSS:

.card {
    transition: transform 0.3s ease-in-out;
}

.card.flipped {
    transform: rotateY(180deg);
}

Adding Sound Effects

Include sound effects:

<audio id="flip-sound" src="flip.mp3"></audio>
<audio id="match-sound" src="match.mp3"></audio>

Modify JavaScript:

function playSound(id) {
    document.getElementById(id).play();
}

$(document).on('click', '.card', function () {
    playSound('flip-sound');
});

7. Adding a Timer and Score Tracking

Timer Implementation

let timer;
let timeElapsed = 0;

function startTimer() {
    clearInterval(timer);
    timeElapsed = 0;
    $('#timer').text('Time: 0s');
    timer = setInterval(() => {
        timeElapsed++;
        $('#timer').text(`Time: ${timeElapsed}s`);
    }, 1000);
}

$('#restart').click(function () {
    clearInterval(timer);
    startTimer();
});

Score Tracking

let score = 100;
function updateScore() {
    score -= 5;
    $('#score').text(`Score: ${score}`);
}

$(document).on('click', '.card', function () {
    updateScore();
});

8. Making the Game Responsive
