On the 91st episode during the 11th season, a question with the "Ask the Audience" lifeline being used ends up showed 100% of the audience providing the correct answer, which was the very first time it has ever happened in the syndicated version of the show.
At the beginning of season 9, the entire studio had a makeover. The hot seat was retired and replaced with a podium in the center where the host and the contestant would stand during the show. A big LCD screen hanging in the studio displays the question and the answers. In season 10, the podium was replaced with a clear tall table and the staircases had colored lights added.
At the beginning of season 9, the lifelines were changed. The "Double Dip" and "Ask the Expert" lifelines were replaced with two "Jump the Question" lifelines, which allow the player to skip the question without having to answer it. However, the player forfeits the amount of money hidden behind the question. The "Jump the Question" cannot be used on the very last question, which is the million dollar question. The "Ask the Audience" lifeline still remains the same.
At the beginning of season 9, some of the rules of the game have changed. The "clock format" was replaced with a "shuffle format." The amount of questions on the money tree went from 15 questions to 14 questions and they were split into two rounds. The first round consists of 10 questions with categories and the second round would contain the last 4 questions without the categories and is also referred to as "Classic Millionaire." The dollar amounts in the first round would be hidden and randomly mixed up and then the categories would be added in and mixed up randomly. Then after the player answers a question correctly, the amount of money behind the question will be revealed and added into a bank, accumulates the player's winnings throughout the game. If the player chooses to walk during the first round, they will receive half of the amount in their bank and if they choose to walk anytime during the round two, they will receive all the winnings in their bank. However, if the player gets the answer to a question wrong during the first round, they will lose the entire bank and leave with a $1,000 consolation prize. If they get the answer to a question in the second round wrong, they will end up walking with $25,000.
During the Halloween week in Season 11, the show had a Halloween theme. The icons for the lifelines were changed and they had different names that represent a Halloween theme, which were picked out by the show's Facebook fans. The "Ask the Audience" was renamed to "Pick the Audiences' Brains" and the "Jump the Questions" were each renamed to "Bat the Question Away". In addition, a new lifeline called "Crystal Ball" was provided during that week. It would reveal the amount of money behind the question, helping the player decide whether they really want to jump the question. This lifeline was also used occasionally during Season 11.
