They can be used for educational purposes, or just for fun. This is called the 9Fisher-Yates algorithm.Memory games are a great way to test your knowledge and improve your memory.

This process continues until the 'currentIndex' reaches 0, at which point all the cards will have been shuffled. We store the current card value in a temporary variable, 'temporaryValue', and then swap it with the random card. The 'randomIndex' is generated using Math.floor and Math.random, which returns a random whole number between 0 and the length of the 'cards' array. Then, using a 'while' loop, we swap the current card with a random card until all cards have been shuffled. This allows us to shuffle all the cards in the array. The function starts by setting the 'currentIndex' to the length of the 'cards' array. It's an essential part of making your memory card game fun and unpredictable. Now let's write the function that shuffles the card data so that the game is different every time it's played. back Įnter fullscreen mode Exit fullscreen mode This is a really simple HTML structure as we will create all the cards dynamically in javascript. Don't forget to add the link tag for the stylesheet in the head tag. The HTML structure for our memory card game will consist of a main container for the cards and a restart button. Inside the folder, create three files: index.html, style.css, and script.js. In your code editor, create a new folder called 'memory-card-game'. To start, let's create a new directory for our project and set up the file structure.

If you would prefer to watch a beginner-friendly step-by-step video tutorial instead, here is the video tutorial that I made.īefore we jump into anything, check out my repository on GitHub for this project, where I prepared an assets folder with the fruit icons that we'll use for the cards, and also created a json file with all the card data that we'll need to implement this game. The game will be restarted when all cards have been matched. The game will have a grid of cards, where each card will have an image and a score system to keep track of the player's progress. In this tutorial, we will learn how to build a beginner-friendly memory card game using HTML, CSS, and JavaScript.
