Evaluation

JOY OF PROGRAMMING launched into Early Access in January 2024 and graduated to its full 1.0 release on January 18, 2025. At that milestone, the developer explicitly stated that 1.0 does not mark the end of development: "I plan to support JOY OF PROGRAMMING for the foreseeable future and add new levels whenever I have ideas for new challenges." The developer has delivered on that promise. A free content update shipped on August 31, 2025, adding two new levels to the Driving category. This is the most recent developer communication on record as of October 1, 2026 — approximately 13 months after the last content drop. During Early Access, major content updates arrived frequently: March 2024, April 2024, May 2024, June 2024, September 2024, and November 2024 — roughly every 1–3 months. Post-1.0, the August 2025 update continued this pattern, though at a slower pace. The developer noted in that August 2025 post that they are currently focused on a second game called Card Coder, which explains the reduced frequency of updates. However, the developer has not announced an end to JOY OF PROGRAMMING's development — only that their attention is divided. The gap since the last update (August 31, 2025 to October 1, 2026 — roughly 13 months) is longer than the typical post-launch cadence, but the developer's own statement of ongoing intent, combined with the documented post-1.0 release and the acknowledged reason for slower output (a second project), means this silence does not yet signal abandonment. No final update has been announced.

A Fair Warning

JOY OF PROGRAMMING is not a casual game. In fact, it is one of the most difficult games on Steam. It offers the real programming experience: Lots of thinking, hard work, gathering information, debugging and some frustrations. But you will also learn new skills, become a better developer, and most of all enjoy that sweet sensation of finally cracking a hard problem.

Features

  • Tutorial levels to get you started with the programming concepts in JOY OF PROGRAMMING

  • Create your own puzzles with the included level-editor

  • Find collectible factsheets with interesting computer-science tidbits

  • Earn stars by completing levels and use them to unlock new programming features

  • Work towards achieving many different certificates for completing all levels in one category

  • Real programming: No pseudo code, no imaginary language. Instead, fully functional python code with your favourite packages like numpy, pandas, scipy, pillow, sklearn and more. Some basic prior programming knowledge (in Python or otherwise) and a strong interested in programming is recommended.

  • In-game IDE: A codemirror based in-game Python IDE offers syntax highlighting, auto-completion, docstring tooltips, debugging, auto-indentation, code-folding, copy/paste and undo/redo. Advanced users can also opt to use external IDEs like VSCode or PyCharm instead.

  • Realistic challenges: From robotics to abstract algorithms and creative coding - the full breadth and depth of computer-science awaits.

  • Open puzzle design: Each level has many different valid solutions.

  • Clear goals: Each level has one mandatory goal and up to three optional goals.

  • Immediate feedback: Never wonder whether your code is working. Get immediate, incremental feedback on each good (or bad) step towards a working solution.

  • Performance metrics: Compare your best solution anonymously with others with respect to speed, memory usage and code length.

  • No hard locks: Never get stuck on a single level, there are always several open challenges available.

  • Optionally submit your solution and your code to the leaderboards and share it with the world.

Designed By A Computer Science Professor

The game is developed primarily by a single developer, who also happens to be a computer science professor. An accompanying Youtube series by the developer provides example solutions for several of the levels and walks through them step-by-step.

Level Editor

An innovative Python based level editor allows creating and scripting entirely new levels with exciting new challenges. Optionally, these new levels can also be shared with the community via the game's Workshop.

Happy Coding and get JOY OF PROGRAMMING now!
