Programming

Build circuits and match waveforms across 101 electronics puzzles. Draw wires, light LEDs, and watch signals change on the oscilloscope. Learn how components work, then experiment with your own circuits in Sandbox.

Run and jump across the graphs of real functions. Every level is a curve — its derivative shapes the platforms and hazards. 40+ stages from parabolas to Riemann sums, AP Calculus BC, physics, and aerospace curves, ending in a Mandelbrot boss. A platformer that teaches real calculus.

Build your dev studio one commit at a time. Upgrade your setup, manage Technical Debt, ship projects, and survive bugs, demanding clients, overheating servers, and security breaches in this incremental developer sim.

An incremental game played entirely through typed commands in a terminal window. You are a machine under contract. Spawn autonomous agents to perform work for you and use the tokens they create to research new improvements to your process.

A modern-day hacking sim. Take bug bounties, sweet talk a help desk, lift credentials, cash out crypto, upgrade your rig, and more. NPCs respond to you in a realistic manner, and remember what you've done.

Simulator of a digitized fruit fly. Press buttons, change conditions and stimuli, observe its reactions, and repeat experiments to uncover the logic behind its behavior. Simple mechanics, strange results, and pure curiosity.

Write code that controls an entire robotic workforce. Start with one worker, then scale to 128. Share jobs, feed machines, and adapt when power fails. Test your code in new facilities, then tune it to do more with less.

In this game, you'll run a cat sushi restaurant on the sea, listening music while coding staff to make sushi. Choose visual blocks or a traditional code editor. Optimize code, boost efficiency, earn coins, expand your shop, hire staff, attract customers—enjoy automation and improve your coding.

Build a plan. Press Run. Guide a very literal robot through a playful sci-fi puzzle adventure. Arrange command blocks, discover clever loops, learn from spectacular wrong turns, and chase the satisfying moment it all clicks.

Design parts, build mechanisms, wire your controller and bring your creations to life with C++ code. PROJECT R1 is a robotics workshop where you move between CAD, assembly, programming and physics testing to experiment, troubleshoot and refine your designs.

An inventory-management auto-battler where your score grows exponentially. Arrange Code Blocks on a grid and let your program run itself. Find the loops and loopholes that push your Payload past every target.

Struggling to piece together fragmented memories and confront internal fears, explore a mysterious world where every discovery reveals another fragment of the past.
