Clever idea, I'll give you that, but I have one complaint with this game... do you expect us to know all of these answers off the tops of our heads? Because honestly, I could get them all with little to no effort until I had to guess 'India's premier nuclear research facility' and 'an Indian TV channel that broadcasts Hindi entertainment'. There's no way I could answer those without first Googling them...
...and now I'm stumped on this one that's just three black circles and the rightmost circle has a second black circle within it. Kudos for originality, but when you take away the hint system partway through, it just becomes impossible... especially if it's supposed to be something that's well-known in a foreign region and unheard of in a place like where I am (Canada).
