Sanket Suchak (संकेत सूचक, literally Signal Indicator) is a lifeline introduced in the 2025 season of Kaun Banega Crorepati, the Indian Hindi version of Who Wants to Be a Millionaire?. When a contestant uses this lifeline, it gives a hint towards the answer to the question it is used on. The hint can be either a video, an audio clip, an image, or a written clue.
