It's one of those games which shows some pictures like a group of people, a will smith and a stone + a you which means we will rock you. there wasn't such a thing in Iran but they made good money with this game and they've got famous as well!

I think it is a sort of a game where you will be given few hints to predict the name of an object or something similar for that matter.

For example, let say I will show you a pic of very small 'N' and will ask you to predict the object that it represents. The possible answer can be micron i.e. Micro N .
