One island. Everyone builds on it.

Plotopia is a city-builder on a single shared map. Claim a parcel, put a building on it and staff it with citizens. What your neighbours build changes what yours produces.

What it is

A city-builder where the map is the mechanic

Most builders let you put anything anywhere. Here, where a building stands decides what it is worth, and the parcels around you belong to other people.

Shared

One island for everybody

No instances and no private worlds. The parcel next to yours belongs to somebody, and an empty one can be claimed tomorrow.

People

A city runs on citizens

Thirteen buildings and a population that has to be born, rested and matched to the work. A city is limited by its people long before its materials.

Offline

Nothing runs on a timer

Close the game for two days and the two days are there when you come back, exactly as if you had watched them.

How it plays

Five moves, learned in your first half hour

Everything after that is doing them better. Every clip below is the game itself, filmed on the island next to the Main Hall.

Thirteen buildings

Seven levels each. The last two are merges.

Raw material, refinery, utility, and three that look after people. Pick a building and drag it through its levels.

The other half of the infrastructure. No power, no cycle, for anybody.

The chain

Ten resources, three steps deep

From the ground

  • Wood
  • Sand
  • Metal

Refined, one step at a time

  • Brick
  • Glass
  • Concrete
  • Appliance
  • Beverage

Burned by everyone, every cycle

  • Water
  • Energy

Three come out of the ground. Five are refined from those, one step at a time: wood and sand become brick, metal and sand become glass, concrete becomes appliances.

Water and power are infrastructure. Every producer burns both at the start of every cycle, whether or not they appear in its recipe, so a Water Works always has customers and a blackout is everybody's problem at once.

Citizens

Your buildings do not run themselves

Every citizen has three work stats, and every workplace cares about exactly one of them. A high-Intellect clerk is wasted in a mine. Matching them is the lever you have.

  • WorkWork costs stamina. Rarer citizens spend it more slowly, but nobody works forever.
  • RestTired citizens recover in a Residential. A city that skips housing runs beautifully for two days and then stops all at once.
  • BornNew citizens come from a Hospital, where two rested parents produce one child whose rarity is rolled.
The block one building reacts to. Half of it is somebody else's.

Neighbours

What stands next to what

Every building looks at the parcels around it and reacts to what it finds. A power plant lifts the refineries near it. Housing suffers next to heavy industry, and the industry does not care.

Range
A square of parcels centred on the building, near enough to plan around and wide enough that your neighbours are in it.
Effect
A multiplier, not a bonus. A well-placed building produces several times what the same building produces in a bad spot.
Catch
Half the parcels in range belong to other players. You can plan around them. You cannot control them.

Shared world

You are building next to real people

One island, one map, one economy. Other cities go up around yours as it happens, and parcels, citizens and resources change hands on the same marketplace. The island opens district by district, from the centre outward.

Get in

Open it and start building

Plotopia runs in your browser. There is nothing to download and nothing to install. Your wallet is your identity on the island.

  1. Open play.plotopia.org in a desktop browser.
  2. Connect your wallet and sign the message it shows you.
  3. Claim a parcel, build a Lumber Mill on it and assign your first citizen.
Nothing to install MetaMask to connect Balances in Topia
You sign a message. You do not send a transaction.

To join, you connect a wallet and sign a short text message proving the address is yours. That signature is free: it is not a transaction, it costs no gas, and it moves nothing. It is how the island knows which city is yours.

Without connecting, you can still look around. You just cannot build.

Questions

The things people ask first

Do I need to download anything?
No. Plotopia runs in your browser at play.plotopia.org. There is no installer, no launcher and no client to keep updated. A desktop browser and a mouse is the whole setup.
What do I need to join?
A wallet. Plotopia uses MetaMask to identify you: you connect it, sign a short message proving the address is yours, and that address becomes your city on the island. Signing costs nothing. It is a signature, not a transaction, so there is no gas and nothing is sent.
What is the currency?
Topia, ticker TPA. Plot purchases, the player-to-player marketplace and the fees the world charges are all denominated in it, and your balance sits with your wallet. The Founder Edition pre-sale is a separate thing and is paid in USDC on Base.
Can I look around before connecting?
Yes. Without a wallet you can open the island, pan across it and see what everybody has built. What you cannot do is claim, build or trade.
Can my friends build on the same island?
That is the whole idea. There is one world and one map. The parcel next to yours belongs to somebody, and what they build on it changes what your buildings produce.
Does it work on a phone?
It is built for a desktop browser. A city on a shared island needs a map you can see and a pointer you can aim, and a phone screen gives you neither.
