Wild Card Knock - Out (K.O.) 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. In the unprecedented Wild Card Knock-Out (K.O.) task, the Top 8 had to compete against the challengers to defend their positions and secure a spot in the final week. 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. Acknowledging the consistent performance of the Top 6, he declared that their efforts earned them a place in the finale week.
