Royal Game of Ur Rules - How to Play
Race seven pieces with four binary dice on the Finkel / British Museum reconstruction. Rosettes grant extra turns, the middle flower is safe, and exact rolls bear pieces off.
A reconstruction, not a single ancient law
Boards and pieces from the Royal Cemetery of Ur show that people played this race more than four thousand years ago, but no complete rulebook survived with every board. The version taught here follows Irving Finkel’s British Museum reconstruction from a Babylonian tablet: a clear, playable rule set used in classrooms and museums worldwide. Other scholars propose variants; this site sticks to one reconstruction so two players never argue mid-game.
The board, paths, and seven pieces
Each player has seven pieces that begin off the board. Your private start leads into a shared middle lane, then into a short private exit before pieces bear off. Only the middle stretch is a combat zone where both colors meet. The distinctive flower squares — the rosettes — sit on both private tracks and in the center of the shared lane.
Four binary dice from 0 to 4
You roll four binary dice (each showing 0 or 1), so the total is always between 0 and 4. A roll of 0 passes the turn. Use the total to enter a new piece or to move one piece already on your path by exactly that many squares. You cannot split a roll across two pieces, and you cannot overshoot a landing.
Captures, the safe rosette, and extra turns
On the shared lane, landing on an enemy piece sends that piece back off the board to start again. The central rosette is the exception: a piece sitting there cannot be captured. Landing on any rosette — private or central — also grants an extra turn, so flowers are both shelters and accelerators.
Bearing off and winning
A piece leaves the board only when your roll matches the remaining steps exactly. The first player to bear all seven pieces off wins. Near the end, having several pieces near the exit often beats one lonely runner that needs a rare exact number.
Rules FAQ
- Is this the only historical way to play the Royal Game of Ur?
- No. Ancient practice may have differed by city and century. This site uses the Finkel / British Museum reconstruction because it is complete, widely taught, and fair for competitive play online.
- What happens if I roll a zero?
- Your turn ends immediately. With only five possible totals (0 through 4), zeros are common enough that you should plan entries and captures knowing a blank roll can interrupt a chase.
- Can pieces capture on the private tracks?
- No. Captures happen only where the paths share the middle lane. Private start and exit squares belong to one color, so the fight concentrates on that contested corridor.
- Do I have to take an extra turn after a rosette?
- Yes — landing on a rosette grants another roll and move when a legal action exists. That bonus is why racing for flowers often outweighs a slightly longer quiet advance.
- Can I play online with a friend on this site?
- Yes. Open a live room from the game page and share its invite link. Your friend can join the same board in a browser, with no account required; same-screen play and four AI levels are available too.
