## About the game

MarsVale is one shared Mars colony that grows as its Instagram community grows. Every few hours it reads one number, the account's total follower count, and builds what that many supporters can pay for. You open the site and see the colony as it is today, in 3D, on the real Mars calendar.

Nobody signs up and nobody is scraped, and no follower becomes a named character without consent. The simulation is deterministic: the same follower history always produces the same colony and the same story.

### Eras

Robots first (under 100 followers), First crew (100), Survival (1,000), Expansion (10,000), Community (100,000), and the Settlement network (500,000 to 1 million). At a million every building is unlocked, and from then on a new settlement opens on the crater rim for every further 10x.

## Features

- **The colony in 3D.** 656 unlockable buildings in 16 systems, from power and life support to habitats and science, opened in eras from the first robotic landing to a city.
- **Nothing is demolished.** Buildings are placed once and never move or disappear, even if the follower count drops.
- **A chronicle.** 40 story arcs, one beat per sol, with supply landings, dust seasons and real Earth–Mars sky events such as oppositions and launch windows.
- **Colony directives.** One shared goal at a time, like gaining 500 followers before the cold, which the colony can win or lose.
- **Codex, annals, time capsule.** A catalogue of every building, the full history of the colony, and a sealed message that opens at a follower milestone. Anyone can verify the seal.
- **Named colonists, by consent.** Comment JOIN under a post of @mars_vale for a colonist with your handle, a job and a home; comment LEAVE to send them home.

## System requirements

Minimum: browser A current browser with WebGL, on a desktop or a phone; network An internet connection: the colony updates from the live count

## Questions people ask

### Do I need an account?

No. You don't sign up, log in or play: following the Instagram account is enough. The colony reads only the total follower count, through Instagram's official API, so it can't tell who followed.

### What happens if followers drop?

The Community number drops too, but nothing gets demolished: construction follows the highest count the colony has reached.

### How do I get a named colonist?

Comment JOIN under any post of @mars_vale. Commenting JOIN means you agree to your username being shown. Comment LEAVE to send your colonist home.

### Is it real science?

It is a fictional near-future settlement inspired by real Mars science: thin CO₂ air, 0.38 g, dust, radiation and a 24 h 39 m sol. Some later buildings are labelled as speculative. MarsVale is not affiliated with NASA, Meta, SpaceX or any space agency.
