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 (about US$0.56) to 500,000 TL (about US$280,000). 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.
The show airs four or five times a week and receives good ratings, ranking from being first to third most watched TV show of the day.
Until March 2008, there was only one 500,000 TL box; but from that moment and on two more 500,000 TL boxes were added to the show, tripling the chance to choose the grand prize box, and generally boosting the bank offers. In the 2008 season, one more 500,000 TL was added, bringin the highest prized box count to 4.
In September 2009, producer Acun Ilıcalı set his mind to make at least one person win the grand prize, hence raising the number of 500,000 TL boxes to 10. Consequently, Ülkühan Yılmaz won the grand prize for the first time on October 24, 2009. He is currently the only person who has ever won the grand prize.
