The show's second season, hosted by Prakash Raj, commenced on 11 March 2013 and ended on 12 July 2013.

[4] After a two-year hiatus, the show's third season commenced with a slightly altered format on 30 May 2016 with Aravind Swamy as host,[5] and ended on 19 November 2016.

[6] K. Sriram, the general manager of Star Vijay, claimed Neengalum Vellalam Oru Kodi to be "the first international format to hit the Tamil television screens".

[8][9] Neengalum Vellalam Oru Kodi is unrelated to the show Ungalil Yaar Maha Latchathipathi, the official Sri Lankan Tamil adaptation of Who Wants to be a Millionaire which aired since 2011 in Shakthi TV.

[10] R. Sarathkumar had hosted a show titled Kodeeswaran, which followed a similar format and aired on Sun TV earlier.

[11][12] In April 2011, Business Standard reported that actor Prakash Raj would host the licensed Tamil edition of the Hindi game show Kaun Banega Crorepati, which was then titled Ungalil Yaar Kodeeswaran.

[11] The title of Kaun Banega Crorepati's Tamil version was later confirmed as Neengalum Vellalam Oru Kodi.

[22] The season commenced on 30 May 2016, with a slightly altered format; such as two contestants per game, a new lifeline called double-dip (replacing the 50-50 option), and the ability for players to set their preferred safe-heaven amount on the money tree prior to playing.

The contestant that places the four options in the correct order in the fastest time gets the chance to go on the "hotseat", i.e. playing the main game.

Players answering a question incorrectly are eliminated from the game and their winnings return to the previous "safe" amount.
