ipygame is a pygame-style API for writing small games inside Jupyter notebooks, primarily for teaching and classroom use. Instead of SDL2, it renders to an ipycanvas canvas output, so it works in environments where you do not have a desktop window (e.g. JupyterLab, hosted JupyterHub).
The goal is API familiarity, not perfect drop-in compatibility. Many common drawing and event patterns work, but the browser and the widget stack impose limits.
For local notebooks (CPython kernels), install from this repository:
pip install git+https://github.com/Kamuyin/ipygame.gitimport ipygame as pygame
screen = pygame.display.set_mode((420, 260))
screen.fill("midnightblue")
pygame.draw.rect(screen, "gold", (30, 30, 140, 80))
pygame.draw.circle(screen, "tomato", (280, 130), 50)
pygame.display.flip()The examples/ folder contains notebooks for basic drawing, input handling, and small game demos.

Some pygame features are not applicable in the browser or are not implemented yet. For a high-level view of what is currently covered, check the API coverage page in the docs.
Performance can be noticeably lower than desktop pygame. Rendering happens through the browser canvas and a widget message channel, so high-FPS loops and pixel-heavy effects pay extra overhead, and there is no native SDL2 window/GPU pipeline like on the desktop.
If you run the examples in JupyterLite (Pyodide), you may see rendering work while real-time keyboard/mouse input does not. This is a limitation of the Pyodide kernel + widget message processing for long-running loops, and it is not something ipygame can reliably fix from Python alone.
Audio is work in progress.
ipygame is based on the work by the pygame and pygame-ce projects and aims to provide a familiar API for educational notebooks. This project is not affiliated with, endorsed by, or a replacement for pygame/pygame-ce.
