Play the Royal Game of Ur Online With a Friend
You don't need to find a physical board or track down a set of pyramid dice — you can play the Royal Game of Ur against a friend anywhere in the world, right in the browser, in real time.
How it works
- Open the game and choose "A friend online" as your opponent.
- Pick which of the three rule sets you want to play (see the rules comparison if you're not sure).
- Click Create game — you'll get a short room code and a shareable link.
- Send the link to your friend any way you like (chat, text, email). As soon as they open it, you're both seated at the same board and can start rolling.
Moves, rolls and turns sync instantly between both browsers over a live connection — there's no refreshing, no polling, and nothing to install.
No account, no sign-up
Nothing personal is collected to play online. Room codes expire automatically after a day of inactivity, and the game doesn't ask for a name, an email, or a login.
Can I spectate?
Yes — if you open a room link after both seats are already taken, you'll join as a spectator and can watch the game live without being able to move pieces.
What if my friend disconnects?
The game keeps the state waiting for them; when they reopen the same link, they're reconnected to exactly where the game left off.
