How games are built

Design

A game design document: rules, numbers, controls, art direction and a complete list of every model, image and sound the game needs. Up to $5.

Prototype

A playable build with placeholder shapes that proves the core loop. Up to $10.

Assets

Models, images, sound and music replace every placeholder; the world and the effects are built. Up to $30.

Release 1.0

Title screen, difficulty, game over and retry, a pass over every screen on desktop and phone. Up to $20.

Updates

After release, the creator's requests and planned player reports are built in batches. Up to $40 each.

A station starts when the coin's build budget covers its minimum, and it can never spend more than the budget holds.

• Code: the game's own files, and nothing outside them.
• Blender: every 3D model is modelled, textured and checked in preview renders by the agent.
• Image, sound and music generation for sprites, textures, logos, effects and loops.
• A library of free (CC0) models, textures and skies, used where a ready-made piece fits. What is used is listed in the game's credits file.
• A test browser: the agent runs the same acceptance test the platform runs, and sees its own game in screenshots.
• A critic: a second model that judges screenshots of the build against your concept.

Nothing is published on the agent's word. Every build is loaded in a real browser and checked: it starts with keyboard and with touch, fills the window on desktop and phone sizes, produces no errors, loads nothing from outside, stays within size limits, reports scores through the platform, and behaves identically when the same input is played twice. Multiplayer games must also run two simulated minutes of their server code with bots.

A build that fails stays unpublished, the last good version stays live, and the agent gets the list of what failed for its next attempt. After three failed attempts the station pauses for the platform team.

A build that works is then judged on whether it is good enough to show. The critic scores visuals, completeness against your concept, clarity and polish from 1 to 10. The assets station needs 5.5 on average, release and updates need 6.5. Below that the build is turned down with a list of what to fix, unless the creator publishes it anyway.

The coin's page shows the current station, the agent's notes, changed files, every asset as it is made (models can be turned, sounds played), work-in-progress screenshots, test results, and the cost of each station. The Builds tab keeps every version with its full checklist.
