Programming

Ever wonder how a GPU draws a triangle? In Hello Triangle, you build one yourself. Wire comparators, adders, and multipliers into graphics hardware, press Run, and watch your circuit draw the screen pixel by pixel—from a single triangle up to a rotating 3D cube.

A puzzle about reading someone else's code and the one-byte mistake. A whole little machine on one screen: 256 cells, four registers, a stack. From "which way the stack grows" to a chain of borrowed code. You win not with the right answer, but with what the machine actually did.

Tiny Shaders is an open-ended programming puzzle game about building image-processing algorithms. Connect simple blocks to design complex circuits, and optimise your solutions.

A co-op sci-fi building game where you and your friends build spaceships part by part, connect power to your machines, and fly with physics-based thrusters. Take off from your planetoid, fly through the atmosphere and out into space, and explore the galaxy together.

A town builder you play in real Python. Write the scripts your heroes run: build, farm, collect taxes, fight off bandits, trade with six islands. Then script the townsfolk too, down to personalities their children inherit.

Welcome to EonDeluge, a turn-based bullet hell game. Two players take turns. One draws the bullet patterns in real time while the other steers through them; at the end of the round you swap, and it goes on until someone's energy runs out.

An open-ended puzzle game about building machines that make modernist art. Program mechanical arms to paint, cut and weld shapes into finished pieces, then refine your machine to be faster, smaller or cheaper.

Build a factory that makes numbers. Mine deposits across a large map, connect arithmetic machines with conveyor belts, and deliver the results to your hub. Reuse old production lines, unlock faster machines, or tackle 42 campaign missions and 25 puzzles.

Build a computer from a single NAND gate, together: online co-op for up to 4 players on one board. Wire relays into logic, memory and a 16-bit CPU with a pipeline and a cache, then program it. Robots in mazes, Nim, even a shooter on your own CPU. Level editor and Steam Workshop.

Program your warehouse robot in secret, lock in, and watch every robot run its program at once. Shoves, conveyor belts and lasers will test the best plan. Race, deliver parcels, knock rivals out or capture flags, against the AI, on one screen or online. Same rules as the Crate Escape board game.

You can't steer. Write your whole plan, press run, and watch it play out. Then the level changes after you commit, so a plan with no slack fails. 81 puzzles, a new daily puzzle with a leaderboard, and every winning plan can be replayed.

Ruleocard is a story-driven logic puzzle game where cards become the rules of the world. Stranded on an island with no memory, arrange your cards, run them, fail and rearrange. Solve 260+ puzzles, master 15 systems, face unexpected events and make choices that change the story.
