US version called "Cut the Question", was brought into use in 2014 for a week-long run of special episodes that featured child contestants, in which it could only be used within the first ten questions. This is also used in the Indian version as a permanent lifeline. However, it is available anytime in the game (except for the highest cash prize question) and participants can choose the topic from which the question is taken from. The difficulty level depends on the cash prize for the question. Double Dip – One of two lifelines created for the Super Millionaire spin-off of the US version. When used, this lifeline allowed contestants to have two guesses at a question, but forbade them from using any other remaining lifelines or from walking away with their current winnings. Contestants can first use "50:50" and then used "Double Dip" on the same question, guaranteeing them the correct answer. When the standard US format incorporated a time limit on questions, the show retired "50:50" and replaced it with "Double Dip". This lifeline was also used in the Russian version (without a clock format) but did not replace "50:50". Three Wise Men – The other lifeline created for the Super Millionaire. When chosen, a sequestered panel of three experts (chosen by the producers) appears via face-to-face audio and video feed to provide assistance. Like "Phone a Friend", this lifeline incorporated a 30-second time limit for its use. This lifeline was also used in the Russian version between 2006 and 2008 but did not feature experts. Two Wise Men – Used in the Vietnamese version of the show from episodes broadcast on 5 May 2020, replacing "Ask Three of the Audience". It has the same function as "Three Wise Men", however there are only two experts instead of three. It becomes available after the fifth question. Ask the Expert – Inspired by "Three Wise Men", this lifeline provided the contestant with one person, an expert selected for them, to help with the question. Unlike its predecessor, this lifeline had no time limit on its use, but was only available after the fifth question; after "Phone a Friend" was removed in 2010, it was made readily available at any time in the game. In the US version, the lifeline was sponsored by Skype for its live audio and video feeds. In the Hong Kong edition, it replaced the "Phone a
