The season had a few changes, including a new lifeline called Power Paplu. This lifeline allowed the contestant to reuse a lifeline that was previously used on another question. (It could not be a lifeline that was used on the current question. For example, a contestant could not use "Ask the Audience"/"Audience Poll" twice on the same question.) Double Dip and Ask The Expert were discontinued and in lieu 50:50 and Flip The Question (also known as "Switch" or "Switch The Question") were revived. The Phone-a-Friend was extended to 45 seconds. The prize for jackpot question was increased to ₹ 7 Crore. The Kaun Banega Crorepati 2013 set was a 360-degree multimedia stage.

The system of Fastest Finger First was also altered. Instead of playing one question, the winner of the leader board formed at the end of three questions, sits on the Hot Seat. (ie. the player who answered the most questions correctly in the shortest amount of time).
