Get it now and dive into your programming adventure!
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.
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.
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.
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!
JOY OF PROGRAMMING Software Engineering Simulator for PC starts at €10.91 at Difmark, 38% under the €17.49 of the official store — but that is a shared account, not a key of your own. If you want a key tied to your own account, the cheapest is €17.49 at Steam.
That €10.91 already includes the Gocdkeys coupon, so apply it at checkout or the store will show you a higher price.
Only 5 offers across 4 stores carry it, and thin supply means the price barely moves.
That puts it 11% under its average of €12.24 since 2025, so today is a better entry point than most days of its life.
That €17.49 key is expensive for what it usually costs.
Worked out from 201 daily records of the Steam Key for JOY OF PROGRAMMING Software Engineering Simulator across 4 stores. See the full price history.
The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.
With the shared account at Difmark you log into an account that already owns the game: it is the cheapest route, but it never becomes yours and the seller keeps the credentials. If they ever lose or change them, you lose access.
The key at Steam costs €6.58 more, but you redeem it on your own account and the game stays there for good. That is the difference between renting and buying.
The 3 Steam Gift offers are pricier than the key and leave more room for error, because they depend on the region and on Steam friendship.
3 of the 5 offers work on US — the Global ones plus the ones issued for your own region.

In this title you get to real Python code to control machines and drones in a 3D programming puzzle sim. Smaller situations build genuine coding skills most of the time, although a few players have noted bugs and realism issues. It's a decent game.
