Building a Fun Hi-Lo Game with Pygame: A Step-by-Step Guide

Introduction to Pygame Game Development

Pygame is a widely used game development library that is extensively popular among game developers. It is a powerful tool that enables developers to create different types of games, whether it is arcade games, adventure games, or simulation games.

In this article, we’ll look at how to develop a Pygame and the advantages of using Pygame libraries.

Setting up the Game

Importing Pygame

Before we begin, you must ensure that Pygame is already installed. Once Pygame is installed, you can begin by importing Pygame in your code.

This can be done by writing “import pygame” in the code.

Declaring Game Constants

Declaring constants in Pygame ensures that you have all the game constants in a centralized location that can be easily accessed and modified as required. Constants that need to be declared for a game include windowSize, black, white, green, blue, red, and FPS.

Initializing the Game Modules

Initializing all needed game modules is the next step. This includes initializing the font module, the mixer module for playing sounds, and the clock module, which synchronizes the game with the frame rate.

Setting Up The Caption and Icon

Adding a Caption and Icon to your game makes it easier for the user to identify the game. The caption is the name of your game, while the icon is the image that is displayed as the game is running.

Defining Game Fonts

Game fonts play a significant role in enhancing the user interface experience. To define game fonts, Pygame has an inbuilt module called “Font,” which initiates the font objects.

Set Up the Text for Game Buttons

Setting up text for game buttons improves the usability of the game, and is best achieved by using the “Font” module to create a surface with the desired text.


In conclusion, Pygame is an essential library for game development that provides numerous advantages. It offers a comprehensive range of useful modules and tools that developers can leverage to build games with ease.

By following the steps outlined in this article, you can quickly start building games with Pygame.

Creating the Hi-Lo Game

The Hi-Lo game is a simple card game where the player has to guess whether the next card in the deck is higher or lower than the previous card. In this article, we’ll build the game using Pygame.

Define our deck of cards

The first step to building a Hi-Lo game is to define the deck of cards. A standard deck of 52 cards is used, and each card is assigned a value from 1 to 13, with Ace being 1.

A card value of 2 to 10 corresponds to their face value, while Jack, Queen, and King have a value of 11, 12, and 13, respectively.

Set up card images

In Pygame, we need to load all the card images used in the game. We can create a list of card images, one for each card.

Declaring the Game Variables

In the Hi-Lo game, we need to declare various game variables such as the current card, score, and the deck of cards. We also need to set up the game over and game start variables.

The Game Loop

The game loop runs continuously and handles all the game logic. The loop consists of various sections, including displaying the current card, handling the player’s input, and updating the score.

Handling PyGame Events

Pygame events are used to handle input from the user. We can use the Pygame.event module to handle input events like mouse clicks and button presses.

The Game Logic

The game logic involves choosing the next card from the deck, comparing the value of the current and next card, and updating the score. We also need to check if the game is over and set the game over variable accordingly.

Button Animation

Animations in a game add a level of interactivity and interest to the game itself. The Hi-Lo game can incorporate some simple button animations to make the game more engaging.

Display the scoreboard

The scoreboard in the Hi-Lo game displays the player’s score and other relevant information such as the number of remaining cards.

Set up the entire display

The final step is to set up the entire display. This involves loading the card images, displaying the scoreboard, and displaying the current card and game buttons.


By following these steps, we can build a basic Hi-Lo game in Pygame. With some modifications, like adding sound effects or multiplayer options, we can make the game more interesting and engaging.

In this article, we discussed the process of creating a Hi-Lo game using Pygame. We defined the deck of cards, set up card images, declared game variables, created the game loop, handled Pygame events, implemented game logic, added button animations, displayed the scoreboard, and finally set up the entire display.

By following these steps, game developers can create a fun and interactive game that engages users and keeps them coming back. The importance of using Pygame in game development cannot be overstated, and we hope this article inspires developers to create unique and exciting games that leverage the power of Pygame.
