With its growing success, Who’s The Murderer received major investments, resulting in striking visuals and immersive effects.
Season 1: In the prologue, the cast were introduced to the case and selected their roles as either suspects or the detective. Suspects received detailed character information and could conceal facts unless directly asked, but only the criminal was allowed to lie.
Season 2: In this season, gold bars were given early but must be returned if votes are wrong. Roles were hidden until revealed. The detective’s first vote was private. Only correct voters could keep gold bars; detectives can earn two, and suspects who remain hidden keep all six.
Season 3: It utilised realistic scenes with original props and settings. Each case has one or two victims, making them more complex than before.
Season 4: It continued using real sets and brought back the detective’s assistant role, played by university students.
Season 5: It used a real cruise ship... as the set for its first episode, kept the detective’s assistant role, and retained the previous seasons’ format.
Season 6: It introduced double detective mode with 7 players and two votes per detective; otherwise, the format stayed the same.
Season 7: It replaced Benny Sa with new and recurring cast members, kept double detective mode, and switched to detective badges. Assistants vote once in round two. Badges are earned for correct votes and MVPs. The top four badge holders (excluding He Jiong) earn "Stellar Detective" titles.
