This is an archive of an old version of the website. We have since rewritten the website from the ground up using more modern technologies. However, we will keep this repository up for any who are interested! The new version of the website is no longer open-source.

🎲 RoyalUr.net

A website for playing the ancient Mesopotamian board game, The Royal Game of Ur!

This repository holds the client code for RoyalUr.net. The server code for RoyalUr.net can be found in the RoyalUrServer repository.

RoyalUr.net was created based upon the ancient Sumerian board game, The Royal Game of Ur, in the British Museum. The original board game can be dated to 2600 BC, and was discovered in a royal tomb in the city-state of Ur in ancient Mesopotamia. Learn more about the game on Wikipedia, or watch a fun match between Tom Scott and Irving Finkel on YouTube!

How much of the game is luck?

The answer is, less than you might think!

If you'd like to learn more about strategy and the role of luck in The Royal Game of Ur, check out our efforts over in the RoyalUrAnalysis repository. In that repository we're currently undergoing efforts to use our computers to help us better understand the strategy and luck involved The Royal Game of Ur.

Join the community!

If you're interested in The Royal Game of Ur, we have a Discord and a Reddit that you might want to check out! These are both good places to talk about the game, its strategies, and see cool board recreations that people have made! The Discord is also a great place to find strong opponents to challenge! We also post updates about the game on our Twitter.

🖥️ Compilation

This project uses Babel to transpile all Javascript to a single ES5 compatible file, as well as a Python script to generate the resource files needed for the site.

The following commands will compile the site to ./dist:
./compile.sh release -- Full clean compilation, with minified JS.
./compile.sh dev -- No minification, no cleaning of ./dist folder.

If you run into ./res file related issues during compilation, try updating your ./res folder.

To update the contents of your ./res folder as the resources used by RoyalUrClient change, simply delete it and let the compilation script download it again for you.

🛠️ Project Architecture

A summary of the architecture of the client-side of RoyalUr.net can be found in ARCHITECTURE.md.

💾 Resource Files

The image, audio, and annotation assets required by the project are not actually stored in git, due to git's poor handling of binary files. Instead, the script to compile the site will automatically download the resources for you from https://royalur.net/res.zip.

A massive thanks to all contributors to the RoyalUrClient project!

💾 Resource Files
The image, audio, and annotation assets required by the project are not actually
stored in git, due to git's poor handling of binary files. Instead, the script
to compile the site will automatically download the resources for you from
https://royalur.net/res.zip.

Repository files navigation
This is an archive of an old version of the website. We have since rewritten the website
from the ground up using more modern technologies. However, we will keep this repository up
for any who are interested! The new version of the website is no longer open-source.
🎲 RoyalUr.net
A website for playing the ancient Mesopotamian board game, The Royal Game of Ur!
This repository holds the client code for RoyalUr.net.
The server code for RoyalUr.net can be found in the
RoyalUrServer repository.
RoyalUr.net was created based upon the ancient Sumerian board game, The Royal Game of Ur,
in the British Museum. The original board game can be dated to 2600 BC, and was discovered
in a royal tomb in the city-state of Ur in ancient Mesopotamia. Learn more about the game
on Wikipedia, or watch a fun match
between Tom Scott and Irving Finkel on YouTube!
How much of the game is luck?
The answer is, less than you might think!
If you'd like to learn more about strategy and the role
of luck in The Royal Game of Ur, check out our efforts over in the
RoyalUrAnalysis repository.
In that repository we're currently undergoing efforts to use our computers
to help us better understand the strategy and luck involved The Royal Game of Ur.
Join the community!
If you're interested in The Royal Game of Ur, we have a Discord
and a Reddit that you might want to check out! These are
both good places to talk about the game, its strategies, and see cool board recreations that
people have made! The Discord is also a great place to find strong opponents to challenge!
We also post updates about the game on our Twitter.
🖥️ Compilation
This project uses Babel to transpile all Javascript to a single ES5 compatible file,
as well as a Python script to generate the resource files needed for the site.
The following commands will compile the site to ./dist: 
./compile.sh release -- Full clean compilation, with minified JS. 
./compile.sh dev -- No minification, no cleaning of ./dist folder.
If you run into ./res file related issues during
compilation, try updating your ./res folder.
To update the contents of your ./res folder as the resources used by RoyalUrClient
change, simply delete it and let the compilation script download it again for you.
🛠️ Project Architecture
A summary of the architecture of the client-side of RoyalUr.net can be found in
ARCHITECTURE.md.
