One of the most interesting aspects of this game is the use of 4 tetrahedral “dice”. Unlike knucklebones that were used for gaming by the Romans and others, tetrahedrons are not easily found in nature and I think they would have had to been manufactured perhaps with some difficulty.
My first idea was that since in this game each die can score either 1 or 0 they were substitutes for coins but superior because they can be picked up with ease. Unfortunately this game predates the invention of coins in 600 BC.
So, if you have any insights it to the origins of tetrahedral dice please share them in the comments.
