History Trivia / DealOrNoDeal

** The 2010 specials used an ''Literature/AlicesAdventuresInWonderland'' theme, with chocolate-coloured boxes. The gameplay edition of "Good and Bad" was retained from 2009 but this time utilised Cheshire Cats. This also led to another player leaving with nothing after finding two unhappy cats.
** While there were no specials in 2011, 2012 reverted back to "Good and Bad Eggs", this time one bad and two good. Good would allow the player to continue the end of the game one box at a time and win a holiday, while bad would allow the Banker to check the player's box. The studio and boxes were decorated by local schoolchildren.

* ChristmasEpisode: The UK version had yearly Christmas editions.

** The same applied in 2006 with the exception of 25 and 26 December. While the afternoon episodes didn't see much other than bonus prizes being won, special evening episodes were the first to feature £500,000 up for grabs, replacing the £15,000 amount in the process.
*** The ending of the Christmas Day evening episode featured everyone singing "We Wish You a Merry Christmas" to annoy the banker, cutting to his office, where you got to see him in person for the first time, although you are unable to see his face and body.
** In 2007, the show began its yearly "Scrooge or Santa" specials. The special gameplay addition was an advent calendar, where contestants would choose a number, which would either be "Scrooge" (allows the Banker to look in the 2/4 boxes or the player's box, allowing a swap if chosen) or "Santa" (Forces the Banker to give out an offer after every box opening and receive some bonus money (£250, £500, £750 or £1,000) from a turkey named Eamonn).
** Following this selection of specials, a separate week of specials, known as "Deal or No Deal Christmas Stars" aired during the Christmas week of 2007. A selection of six contestants, playing for special causes, were chosen to win up to £250,000. The box openers were all family and friends of the player, and the player was allowed to choose whatever box they wanted to play with. These contestants all got bonus gifts and a trophy for playing. These specials happened again in 2008, although only three editions were produced.
** The gameplay addition in the 2008 "Scrooge or Santa" specials instead focused on a large Christmas Tree, with eight doubles - four having Scrooge, four having Santa. "Scrooge" would allow the banker to look inside the player's box with a swap if wanted, while "Santa" once again forces the banker to deliver an offer after every box in the final round, as well as also allowing the contestant to pick up a random holiday destination for two.
** The 2009 "Scrooge or Santa" specials this time had two "Santas" and a "Scrooge". "Scrooge" went for a twist - where the Banker would look inside the box, but nobody else would know what was inside, with box swaps once again offered. "Santa" once again offered up box offers and the Holiday as with the previous year.
** The 2010 "Scooge or Santa" specials were the last year with this specific theme, but this time with snowmen. The rules for gaining a "Scrooge" or a "Santa" were the same as in 2009 although the holiday was not offered for getting a "Santa", as this was instead applied to "Win" or "Lose" miniboxes - which led to the fifth player to walk away with nothing in the UK version.
** The 2011 Christmas Specials went with a "Deal Panto" theme, with a heavy ''Aladdin'' theme. The Genie's Lamp could allow a contestant to win a holiday or be offered every box, as well as choosing coloured smoke - which allowed either the Banker's wish to be granted (Same rules as the "Scrooge" option), or the player's wish is granted (allowed either the usage of the Genie's Lamp, or unwrap a present under the tree, containing either £5,000 or £10,000, or one of the Banker's pair of underpants).
** The 2012, 2013 and 2014 Christmas editions were "Big Christmas Dinner", "Ideal Christmas" and "12 Days of Deal". There were no specials in 2015 once the show's scheduling got inconsistent.

* MilestoneCelebration: The UK version did this quite a bit.
** The first anniversary special, broadcast on the evening of 29 October 2006, featured Jon Culshaw of ''Series/DeadRingers'' as a special guest, first appearing at the very beginning impersonating Noel as he did on the show itself, and later impersonating George W. Bush in the advert breaks. Alex Lovell, the usual narrator for the advert breaks, also got in on the joke, impersonating Ozzy Osbourne. The set also gained a bit of a "Party" feel, with contestants wearing party hats. There was even a ConfettiDrop at the end.
** The 500th episode, airing on 29 June 2007, had the top prize raised to £500,000[[note]]The first time the top prize was doubled was on the 2006 Christmas Specials[[/note]], with the audience all being made up of previous contestants, including the first (and at the time, only) £250,000 winner Laura Pearce, who chose the contestant in a random draw for the occasion.
** The second anniversary special, which aired on 2 November 2007, doubled all the prizes, with £500,000 up for grabs once more. The contestants all selected to choose a player this time round.
** The third anniversary special, aired on 7 November 2008, focused on a large birthday cake which was used in every offer. It also began with three Noel impersonators. The fourth anniversary special, airing on 2 November 2009, used the same gameplay addition as well.
** The Fifth Anniversary specials from 2010 turned into a full week of celebrations, where previous contestants helped out newer players.
** The Sixth Anniversary in 2011 expanded on a larger celebration, featuring two weeks worth of Live Shows, the first time that had happened in the UK version.

* WhatCouldHaveBeen: As revealed in Creator/AlexTrebek's documentary ''Game Changers'', Mandel initially wanted nothing to do with the show. He eventually relented, but had to rehearse what he was given days before taping started.

* MissingEpisode: For some reason, NBC yanked at least two — the very first game of the Million-Dollar Mission (with [=LeAnn=] Rimes) was pulled because the network didn't think a contestant knocking out both $1,000,000 cases right off the bat was a good way to start (she was still given the [[spoiler:$50,000]] she earned), and another because it wasn't exciting enough (although it eventually got on their website, which is now [[OldShame devoid]] of all ''DOND'' videos).

* EnforcedMethodActing: The first time Howie attended a taping was the first time Howie was in the studio. His reactions throughout that first day from seeing the set to watching how the featured contestant played were authentic.

* ScrewedByTheNetwork: Creator/{{NBC}} apparently didn't learn about the consequences of ''Series/WhoWantsToBeAMillionaire''[='s=] WolverinePublicity and, much like ''Millionaire'', the network's actions eventually led to a drop in the show's popularity and subsequent cancellation after four seasons. The show was [[ExecutiveMeddling screwed with]] so often, and so badly, that people got sick of the syndicated version as well, which was canned after two seasons.

* PropRecycling: Of a sort. The U.S. syndicated run used a smaller version of the Deal Wheel (take a metal ball, spin the wheel, run up stairs, drop the ball through [[Series/ThePriceIsRight Plinko]]esq pegs before it lands on spaces that halve/double/triple your money, used as part of several gimmick episodes on the NBC version) as a contestant selection device.
