Compared with the original format, the others have some changes, making them not the same as the original.
Host In the UK original series, the host was
Anne Robinson. Producers chose her with the intention of being both firm to the contestants yet understanding when a contestant gets voted off. However, in producing the show, Robinson began to act cold and harsh towards the contestants. Some international hosts like , , ,
Neena Gupta,
Hülya Uğur Tanrıöver,
Fiona Coyne,
Goedele Liekens,
Laurence Boccolini, and went to the BBC Studio for instruction and training purpose (meeting the UK production team and Anne Robinson) to replicate the presenting style. However, by 2002,
BBC Worldwide (the format distributor of
Weakest Link), decided that it would no longer be required for hosts to present in a firm, cold manner and that hosts can present however they prefer. As a result, some international hosts are nicer and more relaxed to the contestants. The first notable example of this change was seen during
George Gray's tenure as host in the 2002–03 syndicated version of the American edition; other countries where the hosts of the show were nicer were France (2014–15), Turkey (2015, 2019), Finland (2017–18), Cyprus (2017–21), the Netherlands (2019–20), Greece (2019–23), Australia (2021–22), the United States (2020–, although the hosting attitude of
Jane Lynch was more so that of sarcasm, and snarky – reminiscent of her noted
Sue Sylvester character from
Glee), and the United Kingdom (2021– ).
Bridget Maasland, host of the Dutch version, became the first host worldwide not to wear black clothing on every episode. Although she did wear dark and black suits on about half of the shows, she often wore bright colored outfits on the other episodes. Her style of hosting resembles the style Anne Robinson adapted in the later UK shows (post 2005), asking contestants more about their private lives, letting them sing and dance during the voting and talk about more than just the mistakes made.
Maria Kiseleva was the second host to wear bright (she would wear light-blue or white on the 2020-23 revival and in the 2023 unlicensed .
American version Syndicated From the second season of the syndicated version in the United States, after the penultimate round, the last two contestants do not face the clock and the money tree. Instead, the remaining two contestants go straight into the head-to-head round. In the event the Strongest Link is voted off, the Second-Strongest Link decides who goes first.
2020 revival Unlike the original version, the top prize money available increases after each round. The top prize money starts at $25,000 in round 1 and increases by $25,000 per round until round 4. The top prize money in rounds 5 and 6 are set at $250,000 and $500,000, respectively. A minor addition to the game is that of a buzzer added to each contestant's podium. This is used both to bank money (with contestants not only having to say the word "bank" before being asked the question but must also press the buzzer), as well as to reveal the contestant's vote. If the team reaches the target but hasn't banked (already reached or exceeded it on the chain), the round ends immediately with no need to bank once the question necessary to achieve the target has been answered. Some non-gameplay variations were also adapted to the revived series: the contestants no longer handwrite their votes, rather they vote via a touch screen panel, tapping the button of the player they wish to vote off. This screen is also used to present visual information for visual questions – where the host will ask the contestants to identify items that appear on the screen. Additionally, the host will discuss the contestants' mistakes before the vote reveals – with the weakest link being eliminated immediately after the vote reveal. Like season 2 of the syndicated version, once only two contestants remain the game goes straight to the head-to-head round. Changes from this version were featured in the 2021 Australian version – with the top prize being $250,000 and the prize increases for each round being as follows ($10,000, $15,000, $20,000, $30,000, $75,000, $100,000). Although many have come close, the only person to play a perfect game in the 2020 revival was a woman named Kaya in Season 1 Episode 7. She got all 18 of her questions correct during regular play and then 7 correct in the final round (2 were in Sudden Death). She won $67,500.
French version The latest French version (aired from 2014 to 2015) also does not use the clock and money tree for the final round, and in the penultimate round is the 3-player triple stake round for
€15,000 and lasts 90 seconds.
Dutch version In the Dutch version that started in May 2019, just like on the latest French version, round 8 was cut from the format after they aired the show for two weeks. Instead, in round 7, the money triples, and one last player is eliminated after that round. Making the top prize money no longer €10,000, but €9,000. After that, the remaining two contestants go straight into the head-to-head round. However, in the 2nd series, the number of contestants dropped to 7. The top prize money decreased to €8,000, and the 90-second round returned. ==International versions==
