Royal Game of Ur - Rules, History & Strategy Guide

The Royal Game of Ur is the oldest known board game in the world. The earliest surviving boards were excavated by Sir Leonard Woolley at the Royal Cemetery of Ur (in modern-day Iraq) in the 1920s, dating to roughly 2600 BC — over 4,500 years ago. The game spread across the ancient Near East and was played continuously for at least 3,000 years before fading from common play.

The rules were lost for centuries until British Museum curator Irving Finkel decoded a Babylonian clay tablet (dated ~177 BC) that explicitly described how to play. The tablet, written by a temple scribe named Itti-Marduk-balatu, gave us the dice mechanics, the path layout, and the rosette rules — turning a long-mysterious archaeological puzzle into a playable game again. Finkel's reconstruction is the version most commonly played today, including on Arcadia.

Each player has seven pieces and races them along a 14-square track from start to finish. You roll four tetrahedral (4-sided) dice each turn — each die has two marked corners, so the total roll is 0 to 4. Move one piece that many squares, follow the rosette rules, and aim to bear off all seven pieces first.

1. Roll all four tetrahedral dice. Each die shows either a marked or unmarked corner — count the marked corners. Total: 0 to 4.
2. Move one of your pieces forward along your track by exactly the rolled total. A roll of 0 means no movement; turn passes.
3. Land on a rosette (5 special squares) for two perks: your piece is safe from capture, and you get an extra roll.
4. On the shared middle row, landing on an opponent's piece (non-rosette) sends it back to start. The middle row is the danger zone.
5. You must roll exact movement to bear off (exit) a piece — overshooting the final square is not allowed. Win by bearing off all seven pieces first.

• Control the centre rosette (square 8 on the shared row). It's the most contested square on the board — safe + extra roll + blocks opponent passage.
• Don't leave single pieces exposed on the shared row unless absolutely necessary. A single piece on a non-rosette shared square is one bad roll away from being captured back to start.
• Stack pieces when possible — two of your pieces on the same square block your opponent from landing there at all (a friendly stack is impassable to enemies).
• Save your low rolls (1s and 2s) for fine-tuning bear-off. You need exact rolls to exit, so a 1 left in your pocket can finish a piece sitting on square 13.
• Don't fixate on one piece. Spread your race across all seven — a single chase piece is too easily captured. Move whichever piece keeps the most options open.

The Finkel reconstruction (used here) is the most common modern interpretation, but several variant rule sets exist. The "Burnt City" variant uses 10-piece sides and a different rosette layout. Some house rules treat rolls of 0 as a "skip" instead of a turn-pass, or allow rosette doubling. Arcadia uses Finkel's 7-piece, 4-dice ruleset with safe rosettes and extra rolls — closest to the 177 BC tablet description.
