About Ur

The Royal Game of Ur is a 4500-year-old race game from ancient Mesopotamia, recovered intact from the royal tombs at Ur (modern Iraq) by Leonard Woolley in the 1920s. Rules were translated from a 177 BCE Babylonian clay tablet by Irving Finkel of the British Museum in 1981 — the longest unbroken span of any known board game whose rules survive.

How to play

Two players, 7 pieces each. Cast 4 binary throwsticks (or roll 4 coins) — count "1"s for your move. Race pieces along an asymmetric 20-square track from entry to exit. Land on rosette squares for safety and an extra turn; land on a single enemy piece (off rosette) to send it back to start. First to bear off all 7 pieces wins.

Frequently asked questions

How were the rules recovered?

Irving Finkel of the British Museum translated a Babylonian rules tablet (BM 33333) in 1981. Earlier scholars had reconstructed the board from tomb finds but didn't have the rules until Finkel's translation.

How is the Royal Game of Ur different from Backgammon?

Same family but the Ur track is asymmetric (some squares only one player can enter), and rosette squares grant safety AND extra turns. Ur predates Backgammon by ~2500 years.

What are throwsticks?

Four bicolored sticks with one black and one white face. Count the white faces showing — 0, 1, 2, 3, or 4 — as your move. Yields a non-uniform distribution centered on 2 (most likely).

How long is a game?

20–30 minutes. Quicker than Backgammon, longer than Mancala.

The Royal Game of Ur — Rules, History & Strategy

The Royal Game of Ur is one of the oldest board games in the world — playable boards were buried in the Royal Tombs of Ur (modern Iraq) around 2600 BCE, and the rules survive on a Babylonian clay tablet translated by the British Museum’s Irving Finkel. It is a two-player race game: get all seven of your pieces around the track and off the board before your opponent. Fast to learn, genuinely tense to play.

The board and the path

The board has 20 squares in an unmistakable shape: two 3×4 blocks joined by a 1×2 bridge. Each player runs their own private column at the start and end, and both share the central lane in the middle:

Dice: four tetrahedral rolls

You roll four four-sided (tetrahedral) dice, each with two marked corners. Count the marked corners that land up: your move is 0–4. Because it is the sum of four coin-flips, the distribution is binomial — 2 is the most common roll (about 3 in 8), while 0 and 4 are rare (1 in 16 each). Roll a 0 and you forfeit the turn. Good players plan around expecting a 2.

Rosettes: the whole strategy

Five squares carry a rosette symbol, and they do two things that decide games:

The rosette in the center of the shared lane is the single most valuable square on the board: it is safe, it grants a bonus roll, and — in this build — a piece parked there blocks the opponent from passing through the choke point.

Capturing

In the shared middle lane, landing exactly on a square occupied by a single opposing piece sends that piece all the way back to start. You cannot capture on a rosette (it is safe), and you cannot land on your own piece. A well-timed capture in the middle lane can swing an entire game — a piece knocked back near the finish loses a dozen squares of progress.

Bearing off

To remove a piece you need an exact roll to move it off the final square — overshooting is not allowed, so a piece one square from home needs a 1. First player to bear off all seven pieces wins.

How to actually win

  1. Fight for the central rosette. It is safe, gives a free roll, and blocks the lane. Take it early and hold it.
  2. Advance a spread, not a single runner. Multiple pieces in play give you choices when the dice disappoint and more capture threats against your opponent.
  3. Use the safe start. Pieces in your private lane cannot be captured — do not rush them into the shared lane until you can land on a rosette or make a capture.
  4. Weaponize the extra roll. Chaining rosette bonus rolls can move two or three pieces in a single turn — the biggest tempo swings in the game come from rosette chains.
  5. Play the odds. Expect a 2. Position pieces so a 2 lands on a rosette or captures, and so your own pieces are not sitting one common roll away from an enemy.
Also from the ancient world: try Senet, the Egyptian racing game entombed with pharaohs, and Pente Grammai, the Greek “game of five lines.” All three are short to learn and deep to play.
