Jason Sanjay's directorial debut, Sigma, has maintained a steady run at the box office through its opening weekend, with the film continuing to draw audiences even after the weekend rush. The film, however, witnessed the expected dip in collections on its first Monday, with its occupancy dropping to 17.5 percent across 1,520 shows.

On Day 4, Monday, Sigma collected Rs 94 lakh in gross at the Indian box office, taking its four-day gross collection to Rs 6.10 crore. The film's India net collection currently stands at Rs 6.19 crore, according to industry tracking data. Sigma has recorded no overseas collections so far.

The film opened with Rs 2.70 crore on Friday before collecting Rs 1.70 crore each on Saturday and Sunday. Its Monday collection fell to Rs 94 lakh, with the film registering an occupancy of 17.5 percent. Tamil Nadu remains Sigma's biggest market, contributing Rs 3.15 crore to its total gross, followed by Andhra Pradesh and Telangana at Rs 2.18 crore. Karnataka has contributed Rs 47 lakh, while Kerala has added Rs 24 lakh.

An excerpt from CE's review of the film reads, "In a way, choosing to make his directorial debut with Sigma has both benefited and disadvantaged Jason. Debut films serve as a filmmaker's portfolio. The film proves Jason can stage big action sequences and handle multiple characters and their intentions."

The film follows a youngster named Guru (Sundeep Kishan) whose path crosses with a drug racket even as he faces much debt and tries to preserve his familial property. His life situation forces Guru to come up with a heist plan with his friends, with an eye on reclaiming what he and his family have lost, and this leads to chaos and confrontations. Besides Sundeep Kishan, Sigma stars Sampath Raj, Faria Abdullah, Raju Sundaram, Yog Japee, and Shiv Panditt.
