A program featuring participants with unique themes who must distinguish the real from the fake. It is an entertainment program that aired on SBS. It ran for 9 years, from July 2, 1999, to June 17, 2008, with a total of 422 episodes. The first half of the program is primarily remembered as "Lee Kyung-sil and Lee Sung-mi's Truth Game," and the latter half as "Yoo Jae-suk's Truth Game." Initially, the program had two MCs, Lee Kyung-sil and Lee Sung-mi. However, Lee Sung-mi left the show to emigrate to Canada with her family. Subsequently, announcer Yoo Jung-hyun, who was a regular panelist in the early stages of the program, replaced her on August 23, 2002. Lee Kyung-sil also departed after the broadcast on August 1, 2003. Following Lee Kyung-sil's departure, candidates such as Kim Mi-hwa, Park Mi-sun, Kim Won-hee, and Shin Ae-ra were considered, but all declined due to personal reasons. Starting from August 8, 2003, Yoo Jae-suk and Yoo Jung-hyun co-hosted the program. However, after Yoo Jung-hyun declared himself a freelancer and left during the fall reorganization of 2003, Yoo Jae-suk broke the tradition of two MCs and led the program solo for 4 years. Nevertheless, as regular panelist Song Eun-yi often shared hosting duties with Yoo Jae-suk, it can be considered that a two-MC system was maintained. After Yoo Jae-suk's departure on October 30, 2007, Ji Suk-jin, who was a regular panelist during the era of Lee Kyung-sil and Lee Sung-mi as MCs, took over the MC role. However, even during this period, Song Eun-yi acted very much like a host, thus the two-MC format was sustained. Despite being a long-running popular program, it gradually devolved into a promotional show where aspiring celebrities showcased their individual talents. Coupled with the exhaustion of themes, the program's popularity declined. Ultimately, the show concluded with its final broadcast on June 17, 2008.
