As far as I know or at least I heard it differently. That it was a Babylonian Astronomer who send the Tablet to a Greek colleague. 
A casual correspondence between Scholars and the Babylonian spoke about his favorite Game. 
That’s what was said in a video from the British Museum about It from the guy who discovered the rules.

Aha! That's right, there's another fun fact - there are *two* tablets, the one I described, and the one you do. Mine was older, but it was destroyed in the first world war, and we have only pictures of it. The one we still have, carved by a scribe for an astronomer, describes a later version of the game. So we sort of have two or three 'versions' of the rules, from different locations and time periods.
