About This Game

A perforated chassis, a box of parts, and a robot that has to roll. You bolt the mechanics underneath, you wire the electrics on top, you switch it on — and then you find out what you got wrong.

Build with real parts

Solenoids, gears from 8 to 32 teeth, connecting rods, crank pins, bearings, shafts, drive wheels, flywheels, a contact breaker, capacitors, resistors, switches, relays, DC motors, transistors. Every part has a data sheet, real dimensions and a place where it fits. Nothing snaps magically into position: if your two shafts sit a few millimetres too far apart, the gears will not mesh, and the game will tell you by how much.

Nothing is faked

Ten thousand times a second, the game solves a real system of equations to find the voltage at every point of your build and the current in every wire. That is why your machine behaves like a machine. It stalls at dead centre until you fit a flywheel. Your breaker contacts erode spark by spark until they stop conducting — and a capacitor in the right place will save them. The connecting rod tears off if you stretch the linkage too far.

Every failure has a cause, and you can find it

Press F1 and the Encyclopaedia opens: every part, every idea, every fault, cross-referenced. Not a manual — a workshop notebook that explains why the spark eats your contacts, and what a magnetic field has to do with any of it.

What is in the game today

Forty-five build missions across four projects:

• The robot vacuum, 32 missions. From a solenoid you slide by hand to a machine with motors, a brushroll, bumpers and relays that finds its own way. Then you take it home: the hallway, then the kitchen with its chairs to get around, a map of what is still dirty and your best time for each room.
  
• The pinball table, 5 missions. An electromechanical table to build, then to play.
  
• The dart machine, 5 missions. A 1980s bar machine: it hits nothing, it reads. Rectifier, filtering, regulator, matrix.
  
• The electronics workshop, 3 missions. A new bench to learn transistors. This is the youngest project.

And a free sandbox with the parts box open.

The demo stays free

It holds the first twelve robot missions and the pinball table. If you are not sure, start there.

Eight languages

English, French, Spanish, Brazilian Portuguese, Russian, Simplified Chinese, German and Japanese — every text of the game and every page of the Encyclopaedia. Everything beyond French and English was translated by an AI, with the vocabulary of the workshop, and no native speaker has read it yet: if a sentence sounds wrong, say so in the game's message board or on the forum, and it will be fixed.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Some marketing assets on the store page (capsules, logo) were produced with a generative AI tool, based on screenshots and 3D renders from the game itself.

Part of the in-game text (encyclopaedia entries and mission briefings) was drafted with the assistance of a large language model, then reviewed and edited by the developer.

The 3D parts, textures and the simulation itself are authored. Nothing is generated while the game is running.
