Knowing exactly which games played with dice came first is impossible, says Ulrich Schädler, director of the Swiss Museum of Games, unless the materials were carved in stone or bone. Some of the earliest games we can be certain about include one called "20 squares" in which players race counters across a board of 20 squares, some of which are safe, some of which are shared with your opponent, giving them a chance to send your counter back to the start. The game has been likened to backgammon.
Versions of this game have been found in North Africa, the Middle East and Indian subcontinent, the most notable example of which is the Royal Game of Ur, named after the ancient city in Mesopotamia (now Iraq). The Ur board, inlaid with a mosaic made of seashells and played using a pyramid-shaped die, dates to the mid-third millennium BC and is on display at the British Museum. It was Finkel who uncovered its rules.
Another game called senet was played in Egypt around the same time. Several well-preserved boards have been found in tombs of the pharaohs and pictured in wall paintings.
But Schädler says that games like this were not just played by royalty. The Ur board is exquisite, but simple boards were scratched into stone or even the earth. He says it is difficult to know how earlier versions of these games developed if they were played on the earth with pebbles, so boards made for the rich left in burial chambers and illustrations on walls provide the best materials to work from.
"Things like that only appear in the high ancient civilisations like Egypt, Ur and the Indus Valley [around modern-day Pakistan and Afghanistan]," says Schädler.
