Tiebreakers

On Who Wants to Be a Millionaire, a tie occurs when two contestants post the exact same fastest time in Fastest Finger First. This is resolved by a tiebreaker the two contestants answering a second fastest finger question, repeating until one contestant gets the fastest time whether their opponent is wrong or not.

Famous tiebreakers
One of the first tiebreakers in Millionaire history was June 2000, when Kim Hunt and Beth Rohr both posted a fastest time of 4.69 seconds. Hunt won the tiebreaker beating Rohr by 1.8 seconds and eventually became the fifth U.S. top prize winner. Around that same time Marga Lumbers won Australia's first WWTBAM tiebreaker beating out Trevor Ward and was the first woman in WWTBAM history to win a tiebreaker.

The first UK tiebreaker was on March 26, 2002 during a twins special when Andy & Steve Burton and Adam & Charlie both posted a time of 5.62 seconds. Andy & Steve won the tiebreaker and would walk away with £16,000.
