To whoever would wear the Crown

Britain and Ireland lie in a hundred shires, and every one of them has a lord who thinks it his. You begin with one castle, a few farms and a handful of soldiers.

Make it strong. Feed your people, train soldiers, send out scouts, and take the next village - then the town - then the shire. Lay out your own walls and towers, and man them when the enemy comes with ladders and rams.

The other lords will write to you: with offers, with demands, and now and then with insults. Answer them as you see fit. Rule England, and the Crown is yours - for as long as you can keep it.

Play it alone, in your own time - or in the online world, where some of the other lords are real people.

What you will see

Three ways to play

In your browser

  1. Press "Play now".
  2. Wait while the game loads - about 28 MB the first time, much less after that.
  3. Play. The realm you play alone is kept in this browser, on this device.
Play now

Best on a computer with a mouse, in a new Chrome or Edge. The Windows and Android games run faster. If the browser's stored data is cleared, a realm played alone in it is gone.

On a Windows PC

  1. Get the file (54 MB).
  2. Right-click it and choose "Extract All".
  3. Open the folder and double-click "StNicholasCastle.exe".
Get it for Windows

Windows 10 or 11. The first time, Windows may say it "protected your PC": press "More info", then "Run anyway". The game is not signed by a company.

On an Android phone or tablet

  1. Get the file on the phone (69 MB).
  2. Open it. When the phone asks, allow this once: "install unknown apps".
  3. Press "Install". If Play Protect asks, "Install anyway".
Get it for Android

Android 7 or newer. The game is not in the Play Store. For an iPhone or iPad there is no app. "Play now" in its browser may work - it has not been tried there.


Have the game already? Then you need nothing from this page. Start the game: when there is a newer version, the title screen says so, with a button "Update Game".

One Britain, shared

"Play online" takes you into a world that runs day and night. The old lords are in it - and so are other players, each with a castle of their own.

  • Make an alliance, and send soldiers to stand guard in a friend's castle.
  • Declare a war - the other side is told at once, and the war begins some hours later, so they have time to look to their walls.
  • Call your army back when your own walls are in danger.
  • A newcomer is left in peace by other players for the first days.
  • Your lord lives in the world, not on one device: log in from the browser, the PC or the phone and it is the same lord.
An ally is marched upon: you are told who is coming, from where and when.

For parents

How a message is written: a sentence from the book, its blanks filled by picking a place or a player. There is nowhere to type.

This world is run by the person who gave you this address, not by a company. If something is not as it should be, tell them.
