[1][2] The grand finale of the season took place on 19 January 2025, where Muthukumaran Jegatheesan emerged as the winner, while Soundariya Nanjundan was the runner-up.

The season's logo was shaped with two grey semi-circles and the numeral 8 in light blue featuring as the pupil of the eye.

[6] The house was again located in EVP Film City, Chennai for the eighth time, including Bigg Boss Ultimate (season 1).

However, after the eighth week of the show, male and female housemates could sleep in whichever bedroom they wished.

[10] In August 2024, Kamal Haasan announced his exit from Bigg Boss Tamil,[11] due to scheduling conflicts with his upcoming films.

The task featured Muthukumaran, Vishal, Deepak, and Arun as participants, as they were the only housemates still present in the house and on the leaderboard, while the others—Manjari, Jeffry, Ranjith, Tharshika, and Sathya—had been evicted.

Deepak earned the prestigious A-23 Captaincy Crown during his eviction, marking a memorable end to his journey in the house.

For the first time in Bigg Boss history, Penultimate Week witnessed the return of the first eight evicted contestants, not as reunion guests but as challengers.

By the end of the task, one or two members of the Top 8 could be replaced by challengers based on performance, while those who fail will face eviction.

However, on Day 99, Bigg Boss concluded, after a discussion he initiated, that the challengers had not made sufficient efforts to replace the Top 6.

When the buzzer sounds again, signalling the end of this task, both of them will report to the currency counting area to determine the exact amount of money collected by each team.

When the buzzer sounds at the start of each round, all participating members from both teams will need to try to take the coin.
