RAT KING

Begin as one rat in the sewers under a city, and become the Rat King.

What it is

A strategy game about one rat who becomes twelve, bound at the tail, moving as one animal.

The nest

Dig, and the earth pays you

Every room costs scrap, and scrap only comes out of the ground you dig. Warrens, larders, a nursery that raises whatever you are short of — and one panel where you say what the colony should be.

The knot

Twelve tails, and each one weighs

Bind a rat to the King and he grows. Weight is width: a fat King no longer fits the crawl-ways, then not the runs. Each tail gives him something, and each asks a Rite before it will come.

The city above

It does not know you are there. Yet.

Cats in the yards, dogs down the shafts, a rival court of grey rats, gas from the grate and the flood from below — and a man with a lamp who works downward, chamber by chamber.

In the sewer

Three hundred rats across the drain, the yards and the nursery, with the King among them
Three hundred rats is the last night. Forty is a quiet one.
The Exterminator coming down a run with his lamp
The Exterminator: a lamp, bait and a gas lance.
A calico cat in the yard, among the foragers
The Calico comes into the yard, takes one, and leaves.

The numbers

12tails to close the knot
7floors, from the yards down to the cistern
6kinds of rat, and a nursery for all of them
3nests, each saving itself at every dawn

How it plays

  • Tap the floor and the King goes there. Everything you will ever have comes from what he does first.
  • Three orders are the whole of the nest's voice: GO is work, HOLD stands its ground, HIDE takes to the bolt holes.
  • The game teaches itself, one step at a time, and the list in the corner always says what to do next.
  • Plays anywhere a browser does — a phone held sideways, a tablet, a desk.
  • Saves itself in your browser at every dawn. Three nests, so three runs at once.
  • A bug button on the screen sends us a report and a picture of what you saw.

One rat, in a drain, under a city that has not noticed him.
