Double Dip

Double Dip was a new lifeline introduced in the U.S. in 2004 during Who Wants to be a Super Millionaire? and replaced 50:50 in 2009, but was discontinued in 2010 when the Shuffle format began.

Usage
This allowed a particular contestant to make two guesses during the question, but required them to play out the question, forbidding them to walk away or use any further lifelines.
