The game of course is dominoes which is a popular game in Turkey. Maths teachers seem to love the game too and I have drawn a number of domino illustrations for intensive language students and primary students.
I'd love to be back there taking pictures but I get my holidays in December/January which is winter there. I would especially love to go back to Cappadocia but it is cold and snow covered at that time. Just google 'ballooning cappadocia" to see what I want to do.
