Pankaj Tripathi's character 'Sattu Bhaiya' is seen wearing a ludo-pendant in a chain around his neck! This seems to be a reference to how his character's actions have a ripple effect on all the other players in the various story arcs in the film!
Most of the cars have the same number plate prefix "LUDO". Some of the numbers spotted LUDO2345(Shruti's Car)& LUDO1001(Police Car).
Fatima Sana Sheikh and Sanya Malhotra reunite after Dangal (2016).
Apart from directing the film, Anurag Basu has also produced Ludo, written its story & screenplay, worked as a cinematographer and as the film's production designer.
The fourth Anurag Basu film to have a female lead character named 'Shruti'! In Life... In a Metro (2007) Konkana Sen Sharma's chracter, in Barfi! (2012) Ileana D'Cruz's character, in Jagga Jasoos (2017) Katrina Kaif's chracter and in Ludo (2020) Sanya Malhotra's character, are all named Shruti.
