Turkish yoyos?

You can play games:

“The most common toys in the rural areas of Anatolia are tops. The author has recorded more than seventy names for tops in Anatolia. There are also contest games played with tops. For instance, in a game called Tuka, Dozdoz, or Domuz, one contestant tries to hit the other’s spinning top with his own and drive it out of the game area.”

As far as our tricks, you can get them to spin on your hand (even directly from a boomerang although it is probably not very common), and twirl at the end of the string, imitating MGR, etc, but not much more.
