The new luxury budget task that was announced at the start of the day innvolved housemates stealing a coin that'll help them save themselves or others from elimination. Bigg Boss also announced in a letter that this is the first time that such a chance is given to the housemates and that they can either steal one or many coins. The rules mentioned that if a person catches another housemate stealing a coin, then they will be sent to jail till further announcements. The coin they stole will be kept back in place where they belong.
The Bigg Boss house became a museum for the five coins that were placed in the house that represented the five elements of nature. Iykki Berry was the first person to steal the coin with the help of Imman Annachi. She told bigg boss she stole it and hid it inside the bathroom. Akshara Reddy later stole it from the bathroom. Later, Abishek stole another coin and placed it behind the refrigerator. Mathumitha,Abinay and Varun stole the other coins and kept it with themselves.
During the episode, the coins kept passing on with the contestants and were hidden in several places. Many also attempted to steal the ones that were hidden when an announcement came from Bigg Boss saying that only two were taken and the rest three coins were reported missing, He also instructed contestants to show the coins before the camera to prove that they have taken. There were also discussions among contestants as to whom they would save from elimination if they had the power.
Abhinay and Pavni had kept their coins hidden inside the garden area. When Niroop came to pick them, he was caught by Abhinay and other housemates instructed him to keep it back. Niroop, who refused the instructions asked bigg boss to give the correct instructions to proceed further. Later, Ciby read out a notice saying that Niroop will be placed inside the basement jail till further orders as he was caught by Abhinay for stealing the coins. He enthusiastically entered the jail and asked others to play properly.
