Archaeologists have discovered 12,000-year-old dice – here’s what they reveal about the history of play You can compare throwing one of these ancient dice to a coin toss – although this discovery also underscores that dice are much older than coins.

New piece out in @theconversation.com with @apolitopoulos.bsky.social and @docrandom.bsky.social on those early Native American dice everyone’s talking about:

The image shows a rectangular Roman dice tower (turricula) made of four copper alloy (bronze) plates with punched cut-out Latin letters and cut-out decorative patterns. At the bottom front is a stepped exit chute with small bronze bells attached to the opening. The tower is a Roman anti-cheating device. It has an open top and is hollow inside except for three staggered, downward-sloping plates, designed to randomize dice as they fall, ensuring unpredictable dice rolls. When the dice rolled out of the exit chute they rang the bells!  There is a decorative dolphin either side of the stepped exit chute. The top of the front plate has two decorative pine cone finials. Height 25 cm. There is a single die shown next to the stepped base to illustrate how it was used. 

The front  inscription reads:
PICTOS VICTOS
HOSTIS DELETA
LVDITE SECVRI

Translated as: ‘The Picts defeated, the enemy has been destroyed, play in safety’.

Around the top of the three remaining sides, a second inscription made with cut out letters reads:

‘UTERI/FELIX/VIVAS’ translated as ‘Use happily; may you live well’.

Found at a Roman villa at Froitzheim in Germany in 1985.

Roman anti-cheating gaming accessory!

This Roman ‘turricula’ (dice tower) was used to ensure a fair roll of the dice! 🎲🎲🎲

Dice dropped into the top, tumbled over sloping internal levels, and appeared randomly below.

From Froitzheim, Germany, AD 300-400

The British Museum photo shows a six-sided, cube-shaped die carved from rock crystal on a grey surface. The six sides are numbered one to six. The numbers are represented by circular incised markings, which comprise of a dark outer ring with a dark dot at the centre. Length: 9 - 13 millimetres, width: 9 - 13 millimetres. Display lighting casts a shadow beneath the die.

How researchers learned the rules of an ancient Roman board game A team of researchers in the Netherlands set out to decipher the rules of an ancient Roman board game, with an assist from artificial intelligence.

Researchers have used artificial intelligence to model possible rulesets for a Roman board game, concluding it was a kind of game previously unknown in Europe until the Middle Ages, pushing back evidence of their play by several centuries.

The second union of archaeologists in Greece taking a stance on the EAA saga. They represent the contract archaeologists, the largest sector; they call for a boycott: the majority of the local archaeological community in Greece does not support the Athens EAA meeting, under the current leadership.

AI has helped scientists from Heerlen, Maastricht and Leiden confirm a mysterious Roman stone is a real board game—and even reconstruct its rules nearly 2,000 years later. The discovery pushes strategy games further back in time. Curious to play it yourself? 🎲 Read more: edu.nl/u6cgy

The limestone object, about 21 centimetres wide and shown here with stone counters, caught archaeoludologist Walter Crist’s eye in the Het Romeins Museum in Heerlen. To crack its rules, Crist and his colleagues applied an AI-powered game system that contains the mechanics of thousands of games, past and present, from around the globe.

Other explanations don’t fit what we know (too sloppy for masonry guidelines, nonsensical for an architectural plan, decoration doesn’t explain wear, incomplete opus sectile is inconsistent with manufacturing process), a game board is the interpretation that best fits what we know about the stone.

We then analyzed the results of the games the AI agents played to identify those which showed disproportionate piece movement in the same place as the wear on the stone. Nine rulesets, all a type of blocking game like haretavl, produced such results.

We modeled candidate rulesets from these documented games on the different possible board configurations. @ericpiette.bsky.social and @dennissoemers.bsky.social implemented the rules in the Ludii software and designed AI simulated play to track piece movement over 1000 trials of each ruleset.

One such game is haretavl, doucmented in Denmark in the 18-19 century and with archaeological evidence going back to the medieval period, from Ireland to Latvia. One player with three pieces attempts to block their opponent who has one piece.

But, what game could produce this disproportionate wear? We looked to the Ludii games database, with >1000 ancient and traditional games and identified games on boards with a similar number of playing spaces (the intersections of the lines).

We examined the surface further with a microscope. Near the line with visible wear, the microtopography of the stone is flattened. Away from the lines, the surface is lumpy, and identical to the underside of the stone.

We then 3d scanned the stone to look for invisible signs of wear. We noticed that such wear, shown in pink, was concentrated along the lines where pieces would be moved.
