Mastering Rock Paper Scissors: How to Build and Style a Simple Game

Building a Simple Game Mechanism

Are you looking to build an online game that is both easy to develop and addictive for users? One game type that can tick those boxes is a simple game mechanism that pits the user against the computer, with button-based gameplay mechanics.

In this article, we are going to explore the key elements of this type of game, so you can get started building your own today!

Creating HTML Buttons for the Game

The first step in developing your game will be to create the HTML buttons that the user will click on during gameplay. HTML buttons are a basic element and can be added to your web page using simple tags that can be customized to create buttons with a range of colors, sizes or shapes.

Adding Event Listeners to Buttons in JavaScript

Once you have your buttons in place, you’ll need to add event listeners in JavaScript. Event listeners allow your buttons to respond to user actions such as clicks or keystrokes.

Without event listeners, your buttons wont be able to recognize user input and the game will not work correctly.

Fetching User Input and Generating Computer Input

Once your game has its basic functionality, your buttons should be able to generate user input. You can use JavaScript to capture the user’s input and then use the Math.random() function to generate a computer input, which will simulate the computer’s move.

This creates a competitive and challenging environment for the user, which will keep them entertained for longer.

Creating a Function to Compare Inputs and Determine the Winner

The next step is to create a function that will compare the user input to the computer’s input and determine the winner of the game. This function can be implemented in JavaScript using simple if/else statements that compare the two input values.

Once the winner is determined, you will need to update the score.

Improving the Gaming Experience

To make your game more engaging, you should focus on improving the overall gaming experience. Keeping score is an essential part of any game, so it’s recommended to implement a score counter for the user and computer.

This will make the game more competitive and challenge users to keep playing.

Updating Score When a Player Wins

Updating the score when a player wins is the next logical step. JavaScript makes it easy to update the score when needed.

You’ll only need to call an update function to keep track of the score, which should be triggered each time a player wins.

Checking If a Player Has Won Five Times and Declaring a Winner

To make the game more challenging, it’s important to define when a player has won. You can set a limit of five wins and then declare a winner once a player has reached this number.

This adds an additional level of excitement to the game, as both players will need to keep playing to determine who the ultimate winner is.

Resetting Score When a Player Wins

Once a player wins the game, your game should automatically reset the score to zero to start a new round. This means that players can continue to play as many rounds as they wish, without ever having to refresh or restart the game.


In conclusion, building a simple game mechanism can be quick and easy, especially if you are familiar with HTML, JavaScript and the math.random() function. By following these steps, you can create a fun and addictive game that will keep your users entertained for hours.

So, why not give it a try today? With a little effort, you can create a game that will excite and challenge players all over the world.

Styling the Rock Paper Scissors Game

In our previous section, we discussed how to build a basic rock paper scissors game mechanism. However, to make your game stand out from the rest, it’s important to give it a polished look and feel.

In this section, we will explore how to style your game by replacing HTML buttons with images, adding CSS, and updating JavaScript to show player and computer actions as images.

Replacing HTML Buttons with Images

One way to add visual appeal to your game is by replacing the standard HTML buttons with images. This can be achieved by using the HTML tag, which can be customized using attributes such as height, width, and alignment.

You can then use JavaScript to add interactivity to your images by using mouse events such as onMouseOver, onMouseOut, and onClick. These events will allow the user to interact with the images just like they would with clickable buttons.

Adding CSS to Improve the Game Interface

In addition to replacing buttons with images, you can also improve the user interface by adding CSS. CSS stands for Cascading Style Sheets and is used to style HTML elements.

You can use CSS to change the background color, font, image, and layout of your web page. This will allow you to create a unique look for your game and make it stand out from the crowd.

To implement CSS, you can add your CSS code to either an external stylesheet or to the section of your HTML code.

Updating JavaScript to Show Player and Computer Actions as Images

To create a more immersive game experience, it’s recommended to update your JavaScript to show player and computer actions as images. This can be achieved by using the tag to display the corresponding image for each player action, rather than just displaying a text result.

This will help to engage players even more and create a more memorable experience for them.

Summary of What Was Learned in the Article

In this article, we learned how to build a simple rock paper scissors game mechanism using HTML, JavaScript, and CSS. We covered topics such as creating HTML buttons, adding event listeners, fetching user input, and comparing inputs to determine winners.

We then explored ways to improve the gaming experience, such as keeping score, checking for a winner, and resetting the score when a player wins. Finally, we discussed how to style our game by replacing HTML buttons with images, adding CSS, and updating JavaScript to show player and computer actions as images.

Optional Future Improvements for the Game

Once you’ve built a basic rock paper scissors game, there are several future improvements that you can consider making. For example, you could add more player options, such as lizard and Spock, to increase the complexity and challenge of the game.

You could also add multiple levels of difficulty to the game, such as easy, medium, and hard, allowing players to take on greater challenges as they progress. Finally, you could add sound effects to the game to make it even more immersive.

All of these additional features will require further development but can help you create a more engaging and exciting gaming experience. In this article, we learned how to build a simple rock paper scissors game mechanism using HTML, JavaScript, and CSS, and how to improve the gaming experience by adding visual appeal and sound effects.

We discussed topics such as creating HTML buttons, keeping score, and updating JavaScript to show player and computer actions as images. By following the steps outlined in this article, readers can create a fun and interactive game that will keep their users entertained for hours.

As technology continues to advance, it’s more important than ever to have a basic understanding of coding and game design, and creating a simple game like rock paper scissors is a great place to start. So why not give it a try today?
