Var mısın? Yok musun? is a Turkish adaptation of the game show Deal or No Deal. Produced by Acun Ilıcalı for Show TV, the show has been aired between September 10, 2007 and October 31, 2009 and in the second half of 2010. Within 350 episodes from 2007 to 2009, the show awarded around 23-24 Million TL to the contestants and donated around 7-8 Million TL several charities and institutions.

There were 24 boxes containing prizes from 1 TL to 500,000 TL. The set is similar to the French version, but the theme music and the graphics are similar to the US version. The offers are made by "Hamdi Bey", a fictitious character portrayed as a banker; although in February 2008 it was claimed that "Hamdi Bey" was in fact a studio assistant to one of Acun Ilıcalı's former shows, and his name was not Hamdi but Birol; but Acun Ilıcalı dismissed the claims.

A New Year's Eve special was aired on December 31, 2007. The set was nearly identical to the US version. There were 26 cases, all held by models, containing prizes from 1 TL to 1,000,000 TL and the player won 125,000 TL.

Although two different versions of Deal or No Deal had aired in Turkish TV's before and none had been successful, this version of the show was a hit from the first day it was broadcast.
