I can't find the answer to the wall rug puzzle in the turkish exhibition?

I figured out that the most right one has to have 8 filled spots (from left to right +2 -1 filled)

And then I just tried all the combinations

It is 8 filled, 9 filled, 8 filled.

I got it and I think it is eight 9 eight

8 dots, 9 dots and I think 8 for the last one. It opened up before I could see the last one for sure.

First dice and third dice are the same(8 dots are black) the very middle dot (2nd dot on second row ) is the only one white, all other dots black.

Second dice ( 9 dots ) all dots are black

Count the dots on each row. Apply the same sequence to the last row to get the missing value. That will give you a 3 digit code
