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!

To start, I have several years of professional python scripting experience as a sys admin. In game documentation is awful. Spinning the robot arm is the most unintuitive thing I have done. I thought this would be a great way to help others learn python but after testing it I would not recommend it as a learning tool, just as a frustration tool. Tutorials fail to teach basic concepts in a usable way. Just stay away unless you want to hate programming.
This game is _mostly_ great! The programming tasks are manageable, fun, and instructive, the UI is useful and adequate to the tasks, the levels are varied and interesting. What brings the whole thing crashing down is the author's inability to specify the task in terms that don't force the player to guess what he means. Examples: The Platform's input coordinates are described as relative, but they're actually as absolute as the Waypoints. The Drone lets you apply force to the left and right, units of force are specified but then we're told that "weight is ignored." If weight is irrelevant then we're talking acceleration, not force. Also, how do "left" and "right" allow you to move in 2 dimensions? As seasoned software developer, I found myself completely frustrated by the inadequate task descriptions.

As a Software Engineer in the current AI-pocalypse, this game is a refreshing take on coding without any AI and just pure logic and skill. I haven't yet completed the game but each level so far has been creatively crafted. And gaming-coding is imo the best way to learn coding. So a 100% recommendation to those who are beginning their coding or want to go back to their basics.
It scratches my brain just right. I work in manufacturing as a developer, so this kind of problem-solving feels right at home (at least the manufacturing scenario which is what I'm working on now). That said, this game will absolutely test your patience. It forces you to think outside the box, experiment, fail, reset, rewrite, and test again, just like real development work. The tutorial is pretty lackluster, and I would not call it beginner-friendly. The documentation is simple, but it does its job by providing the classes and methods available to you. What makes the game stand out is that it feels less like a tutorial and more like a programming sandbox disguised as a puzzle game. It gamifies the kind of trial-and-error thinking you use in real-world scenarios. Unless you are a top-tier developer, expect to spend a good amount of time on each scenario. You will be clearing code, starting over, and debugging your own logic constantly. Grab a rubber duck; you will need it. I’m grinding through it, and honestly, that is part of the appeal. Much like real programming, if I get stuck, I step away and come back later. The ah-hah moments happen after giving yourself a break that's true in real life as well. Every developer, whether new or experienced, should practice coding regularly. This game gives me a fun way to do exactly that. TL;DR: Not very beginner-friendly, but it offers a fun programming sandbox where both newer and experienced developers can sharpen their problem-solving skills.
I want to like this game but it is buggy as hell. Command count bug that was known back in 2024 still exists in 2026. Finding the exact float value that won't make the physics object fly off the screen when you touch it takes longer that figuring out the proper code to finish the level.
I did not enjoy this game at all. I thought it would be about a lot of puzzles that you need to create creative and clever algorithms for. Instead I spent much more time repeatedly learning about the new systems and what commands they take, and then once I had learned the commands the puzzles felt incredibly simple and straight forward. I don't need to learn the commands for a new fictional digital system every 30 minutes. I want to solve puzzles where I have to cleverly design algorithms and figure out what conditionals and loops I need to implement. Instead, it seems like the puzzles are all fairly simple but their "challenge" is that you need to relearn the environment every time. That's not a coding puzzle, that's just resetting your environment and forcing you to build from scratch.
I love Programming and programming games but JOY OF PROGRAMMING has horrible (if any) instructions and you mainly stumble your way through the tasks by trial end error. I refunded it after 90 Minutes of Playtime.
since you edit code directly from the .py files on your computer, you can literally use neovim, vscode or the code editor of your desire 10/10
I can see the effort and the good intention in the game. But even if I have seen some basic coding back in my days and have messed around with macros in Excel a bit, I'm utterly lost in trying to figure out what the correct syntax is for anything in Python. I suspect the developer found it to be obvious, as for him it really is just that. For me however, it was not exactly a joy inducing experience trying and failing for twenty minutes to figure out if I should or shouldn't have a space or dash or whatever between two characters in my code. There are some confusing elements even in the tutorial, like at first it wasn't even clear that I was expected to achieve the speed setting of the conveyor belts via writing code, because it can be done manually, so I assumed the goal was to see how to control a conveyor belt with various speed settings on the slider and the game accepted it as a solution. As such I probably skipped right past some coding basics. Eventually I'll redo the tutorials instead of refunding the game on the spot, but even if I manage to figure it out, I'll be well past the refund limit. With all that in mind, I suppose this can be a good learning game because you get positive reinforcement and a visual feedback of machinery functioning based on your code, but I would only recommend it to people with some coding experience or a lot of time on their hands, when the game is on a heavy discount. Personally I would be refunding it if I wouldn't have picked it up at a 50% discount.
As someone who is learning Programming, this game is AMAZING, my recommendation for those like me who are not good at programming whatsoever, ask the ai for help, learn the basics, learn to think logical, this "game" is all about understanding what the level is asking for, thinking of solucions and finally asking for guidance with the AI. I am currently on the level call "Triangulation", following the processes i have been using thus far, and also learning the basic concept of Triangulation. For me is a win win.
