So your rules are pretty far off from the rules we know of today. Even when you first published this we translated some betting rules to know what the game play was like. Otherwise not bad at all, if you want to look into this the British museum has videos on it specifically some with Tom Scott a youtuber.

I appreciate the feedback. It's funny you mentioned Tom Scott, since this project uses the simple version of the rules featured in the video where he plays Ur on a physical game board against Irving Finkel of the British Museum. It was actually one of the first videos I watched before starting everything, and I was hooked right away. Thanks a lot for trying out the game.
