Introduction
JavaScript is an open-source programming language. It is designed for creating web-centric applications. It is lightweight and interpreted, which makes it much faster than other languages. JavaScript is integrated with HTML, which makes it easier to implement JavaScript in web applications.
In this ‘Introduction to JavaScript Games’ article, we are entirely focussing on the practical application of JavaScript in real-world web applications. We will be building two games based entirely on JavaScript throughout this article, so brace yourself and start your JavaScript journey!
The two games that we are going to build are:
- JavaScript Game: Snake
- JavaScript Game: Tic-Tac-Toe
JavaScript Game: Snake
Let’s go ahead and build our very first JavaScript game that looks and feels exactly like one of those old-school Nokia snake games. The logic is not very complex and we think you’ll have fun developing this game, so let’s get started!
Fig: JavaScript Game: Snake
You can use any text editor of your choice for developing this game. Using Visual Studio Code is a great IDE for various programming languages like JavaScript and Python.
Our area of focus will be on three aspects of this project that we will work on:
- HTML - This file is the base file for this project and houses the contents of this JavaScript game.
- CSS - This is a stylesheet that we use to stylize various elements of our game.
- JS - This JavaScript file contains all the magic that happens behind the scenes for this game to work.
Project Directory
The Project Directory should look like the image attached below, in the end. This project is inspired by a GitHub repository, and therefore a license file is included in the project directory to comply with the software distribution and modification conditions.

- This file contains the basic HTML boilerplate code.
- Import CSS stylesheet inside the head tag.
- The title of the game, as usual, is defined within the head tag.
- The layout of the web page is within the body tag.
- We are using the canvas tag to design the game.
- Include the javascript file in the end, within the body tag.

- “use strict” gives an error when a variable is declared without specifying its type. This leads to cleaner code.
- We declare all the variables that we will be needing in the game and set a default value.
- We define a function ‘initialize()’ that initializes the game canvas onto the screen:
- We select the corresponding HTML elements by ID and store them in a variable.
- Next, create a game area and then define its width and height, along with single-cell size.
- Then, we set the game by clicking on the ‘start game’ button.
- We define a function ‘startGame()’ that performs the following operations:
- Sets the initial score to 0.
- Sets the starting snake direction to the right.
- We store the game speed inputted by the user and validate the input.
- Snake is declared as an array and is initialized with a single cell value by pushing the cell width.
- We call the createFood() function that creates a food cell randomly on the canvas.
- Lastly, we reset the timer and then set the timer according to the game speed.
- We define a function ‘createFood()’ that creates the food at random locations on the canvas by doing the following:
- ‘snakeFood’ is a javascript object that has ‘x’ and ‘y’ names having values for width and height respectively.
- Width and height are kept random at every function call to create food randomly on the canvas.
- We define a function ‘createGameArea()’ that performs the following operations:
- We set the snake x and y-axis to initial values.
- Then we fill the ‘gameArea’ with white color and border as dark gray.
- We then adjust the snake’s x and y positions according to its direction.
- Then we check for abnormal values of the snake’s x and y-axis:
- If true:
- We call the ‘writeScore()’ function that shows up the score on canvas.
- Reset the timer.
- Enable the game start button.
- And stop the game.
- We also check if the snake encounters food:
- If true:
- We add that food to snake size.
- We create a new food on the canvas.
- Else:
- We pop a cell from the snake’s size when it moves forward and assign it to ‘newHead’.
- newHead is added to the beginning of the snake array.
- Then we loop through the snake array and create squares by calling the createSquare() function according to its length
- We also create a square for the snake food by calling the function.
- We define a function Control(x, y, array) that checks if the snake hits itself, and returns true if it does, false if it doesn’t.
- We define a function writeScore() that prints the user score on the screen and when the game ends:
- We set the font size and family.
- Then, we set the font color.
- After that, we set the game area to show the text on the canvas.
- We then define a function createSquare(x, y) that creates a square for the given x and y-axis:
- We define the color of the shape.
- Then, we define the cell dimensions.
- Lastly, we define the function changeDirection(e) that changes the direction of the snake, by the following ways:
- We first take the keypress event and store the key value in a variable.
- Every key on the keyboard is assigned a number.
- We identify which key is pressed by checking its number and then move the snake in that direction.
- Then we set the events to the screen by doing so:
- Whenever a key is pressed, changeDirection() function is called.
- The initialize() function runs whenever the windows loads.
app.css
This file contains the code that we use to stylize the elements of the snake game. Let’s go through the stylesheet and understand all the styles applied to this project.

- Define CSS styles for the body, which includes background, font styles, and basic layout.
- Define the style for the input element.
- Define the look and feel of canvas.
- Define the position of the Simplilearn logo.
End Result
The game should look and feel like this in the end, though you are free to tweak the logic and style of this game and make it your own!

JavaScript Game: Tic-Tac-Toe
Now that we have created the first game based on JavaScript, let’s move onto building our next JavaScript game which will be tic-tac-toe. The very same game that we are used to playing since school. So without further ado, let’s get started!
Fig: JavaScript Game: Tic-Tac-Toe
Like in the previous game, we are going to concentrate on the three aspects, namely:
- HTML
- JS
- CSS

- The layout of the web page is within the body tag.
- Create a player entry form.
- Create the main game container which will be hidden at first and is only visible once the player entry has been submitted.
- Add the Simplilearn logo.
- Add a reset button that will be visible when the game starts.

- The“use strict” gives an error when a variable is declared without specifying its type. This leads to cleaner code.
- We add a listener that loads our game.
- Initialize the gameboard as an array of empty strings.
- Initialize the turn to the value of 0. It keeps track of a user’s turn.
- Set winner to false initially.
- Then, we define a function player that takes a parameter, name. And then returns it.
- We also define the variables for storing player names.
- Initialize app by creating an app() function:
- This function creates an input field variable that selects the input-field HTML element
- We also attach events to start the game and reset the game button.
- Define a function that handles adding players, by doing the following:
- We first check if both the input fields are entered, if not we show an alert instead of proceeding forward.
- If both user names are entered then we hide the input form and show the game board.
- We store the usernames and then call the ‘buildBoard()’ function.
- Define a function ‘currentPlayer()’ that returns the current player by checking if the turn is even or odd.
- Also, add an event listener that resizes the game board if the browser resizes.
- Next, we define a function ‘onResize()’ that resizes the game board whenever the browser resizes.
- We then define a function ‘buildBoard()’ that builds the game board, the following way:
- We first reset the container.
- Then call the following functions:
- onResize()
- addCellClickListener()
- changeBoardHeaderNames()
- We define a function makeMove() that add a value to a selected HTML cell element:
- If the cell already has some value, we don’t allow the user to enter a new value.
- Else, we check if the player is X or O, if X, the cell gets the value X, otherwise O.
- We then check if there is a winner.
- Update the turn so the next player can play.
- Change the board header according to the player.
- We define another function ‘isWinner()’ that checks and declares the winner:
- We first store the winning sequences in an array.
- Then, we take 3 cells at a time and check if all the cells within the winning sequence belong to the same player.
- If they do, we declare that user as the winner.
- To display the player name, we check if it is player X or player O, then according to that we display the player name in the header along with the congratulations message, and return true.
- If there is no winner, we call the function checkIfTie() and return false.
- We then define a function changeBoardHeaderNames() that changes the player names in the header:
- If there is no winner, this function changes the header content to the player name whose turn is next.
- We also define a function resetBoard() that resets a board:
- Gameboard cells are set to array of blank strings.
- We set all the values to default, set turn to 0. And winner to false, to restart the game.
- In the end, call addCellClickListener() so it listens when the user clicks on a cell.
- In the end, we define functions for adding and removing cell click listeners, that respond whenever a user clicks on a cell.
