The reason Crystal Maze is so popular is because the original presenter was the same Richard O’Brian that wrote The Rocky Horror Picture Show and starred in it beside Tim Curry. The show was rebooted and there is an actual place where people can go to experience the Crystal Maze challenges

The Krypton Factor was truly hardcore. You had to complete the army obstacle course, so you needed good physical ability, but you also needed great general knowledge, to be able to land a plane in a simulator, to observe differences and so much more. Truly had to have skills in every area

British 'Deal or No Deal' is different to US version, where I believe the boxes are carried on by glamourous models. Here they just sit in front of the contestants the whole time. It started here the same year as in the US but was originally a Dutch Format. One of my favourite Mastermind moments ever was a guy who chose to answer on some aspect of Japanese history, and managed to correct the pronunciation of the host on each question, and still get more points than anyone else on that round! (which is strictly timed) You can claim American Gladiators- it started about 3 years before ours. 'Millionnaire' on the other hand was ours!

Both the UK and US version of 'Deal or No Deal' are based on a Dutch gameshow. 'Family Feud' is called 'Family Fortunes' in the UK.

If you think Mastermind was difficult with obscure questions? One they missed which has been going since 1962 is 'University Challenge'. Two teams of University Students, representing their University or University College, being asked British University level specialist questions. Most viewers would be content in being able to answer somewhere near 20% of the questions? Some of the older shows from the sixties through to the nineties are worth looking at, due to some of the contestants now being famous comedians, writers, politicians etc..........

The Crystal Maze was one of my favourite shows as a kid. My sister and I would watch with our mum just before bed. Super chaotic, with an irreplaceable presenter and great atmosphere. Always wanted to try it out.

If you're intrigued by Countdown, there's a popular variation known as 8 out of 10 cats does Countdown. It originally started as a one-off mash up show where the hosts and contenders of the satirical show 8 out of 10 cats did an episode of Countdown. It proved a huge success that it became a regular thing. Deal or No Deal, unfortunately, isn't British in origin. It first aired in the Netherlands in 2000 and was adopted by the UK in October 2005 and the USA in December 2005. American Gladiators was the first in the format introduced in 1989. It arrived in the UK in 1992. It was rebooted in both the UK and the USA in 2009 but, as you said, they weren't as popular as the original run.

The Crystal Maze was so popular there are now 2 Crystal Maze experiences where you can go and have a go at some of the games. I went with my office to the one in Manchester it was brilliant

Blankety Blank was a popular TV game show in the UK. I'm surprised it's not included. I believe it was based on a US TV show, where celebrities guessed words that would fill in the blanks of a sentence. It was hosted over the years by three different hosts. Terry Wogan, Les Dawson and drag queen Lily Savage, more commonly known as Paul O'Grady. All of those hosts are no longer alive. Paul O'Grady passed away early this week aged 67.

The Crystal Maze, Krypton Factor and Catchphrase are my top three I loved those shows so much. :)

I loved Telly Addicts when i was a kid. Great show.

My kids loved the Crystal Maze. My 4 year old daughter used to just ask me to put on the Baldy Man. She loved Richard.

the crystal maze was good the host was the guy who wrote the musical the rocky horror and yes we also have family fude we call it family fortunes

You can't beat carrot in a box 😀

I'm lucky enough to have grown up with British gladiator Cobra (mick) and his younger siblings as they lived a few doors from me growing up. I grew up watching all of these programs lots of them being my favorites.

How on EARTH did Mojo have the brass neck to omit The Chase, Only Connect and University Challenge, AND totally snub game show god, Bradley Walsh? How DID Bradley's legendary 'Fanny Chmelar Moment' not get in to this compilation?

Some of this has probably been mentioned already but here goes: 2:51 Deal or No Deal originated in Holland. But yes the British version came after the US version. 4:13 Closest thing on this side of the Atlantic was a sports themed quizzer on ESPN called 2-minute drill. 5:37 Gladiators originated in the US, several countries have adaptated it. 7:51 There was a pilot for a US version for Game Show Network but it didn't get picked up. 10:15 Millionaire originated in the Uk, producer Micheal Davies was trying unsuccessfully to get a reboot going of the $64,000 question in the US, after seeing millionaire in the uk, he told his business partners "I know what we're doing wrong!" He bought the US rights and....history.

The Crystal Maze is awesome and was a favourite of our family in the 90s. They released a couple of series more recently too. My kids loved it. It can be so stressful to watch at times!

It took three auditions before I qualified to get onto Countdown as a contestant, it was an amazing experience

Crystal Maze was/is the epitome of brilliant game shows. When I moved to Australia from England in the 80s, my Mum would record it on VCR and send me the cassettes in the mail!

Tyler, a little bit of trivia for you is that Countdown was the first show to be broadcast on Channel 4 when that channel started on 2nd November 1982 and it's still going strong today over 40 years later.

Oh, boy. The Generation Game was a staple in my Kiwi household. Bruce Forsythe was a living legend even back then. So many awesome little catchphrases. And the way with words he had. Along with the connection to pretty much every contestant. Was a joy to watch. I can vaguely recall the theme.

The game show Catch Phrase is a game that was created in the United States of America. The show was on American televisions from 1985-1986 before it was picked up by the UK and eventually by Australia.

They had a kids version of The Crystal Maze for the Christmas special. A few of my friends at school planned to go on together even wrote our parents permission slips (we were around 8/10) not knowing at the time it was a random bunch of people put together. It was always my favourite show, had the boardgame and signed up at the chance to bring it back. First as an immersive experience, then they brought it back on screen but something was missing. Richard O Brien was the ultimate presenter with the humerus quips, and loads of clueless contestants who got locked in standing on the spot. It was amazing to watch. I believe R.O.B influenced my sarcasm and the CM my love for escape rooms. All that's missing is getting a Crystal ( I got one saying "I built the Crystal Maze"), and to experience being in the dome, and hear the phrase.. "Will you start the fans please". You may be able to find an episode or two on KZfaq to watch. If you do check out each host but Richard O Brien is legend status.

"Treasure Hunt" was one of the greatest British 'game shows' in my opinion. It deserved a mention in my opinion and I kind of wish they'd bring it back. You should look it up, not only is it a great game show but it is a great way to see Britain ... 1980's Britain anyway. The other classic "hunt" of UK game shows has to be "Bargain Hunt" ... you just can't get more British that that, lol. Perfect daytime telly.

I think our love of TV game shows comes from our love of family party games at Christmas get-togethers. People from a certain generation just love to have fun in an old-fashioned kind of way.

Well done on the SARCASM buddy ! Deal or No Deal was invented by ENDEMOL UK and sold to 45 countries. First shown in the UK in 2005. On Mastermind you choose your own specialist subject followed by a General Knowledge round. The highest score wins. Millionaire is a British game show. Started in 1998 and still runs today. Countdown has a hilarious spin off called 8 OUT OF 10 CATS DOES COUNTDOWN. A mix of 2 different shows. Hosted by Jimmy Carr and has different comedians on 2 panels solving numbers and words rounds.

Deal or No Deal is a British game show, hosted by Noel Edmonds, which aired from 31 October 2005 to 23 December 2016 on Channel 4.(pretty much started same time as US).

Deal or no deal originally came from mainland Europe. My husband and I watched it in Paris, years before it came to the UK. Didn’t understand the concept, at all! Then when we got it in the UK, we were hooked! I remember hearing that when Who Wants To Be A Millionaire was run past the commissioning boss, they had the people in the office as the ‘audience’, for one of the three lives of the contestant, and specific people as the ‘friend’. Family Feud comes from our Family Fortunes.

You can find full episodes of many of these shows on KZfaq. Would love to see you react to some of them. A new one I really like is called I Literally Just Told You. As others mentioned, watch 8 Out Of 10 Cats Does Countdown. It’s a comedic mash up of a panel show, 8 out of 10 Cats, and the game show Countdown. The US has also done spin-offs of The Weakest Link, The Chase, and just last year, a version of that Generation game called Generation Gap, hosted by Kelly Ripa and features her dad. The UK does have Family Feud but it’s called Family Fortunes. One of the few shows they borrowed from the US.

CONGRATULATIONS! You have won tonights Star Prize! Family Feuds is a US show from 1976 and is actually one the UK copied in 1980 and renamed Family Fortunes

I longed to do The Crystal Maze ... but was too chicken to apply. I just know on my challenge - I would have failed and been locked in the room. My friends would never have let me forget it if that had happened !!!😅

Master Mind is an intelligent quiz contest. There are four contestants in each show who have to answer questions firstly on their specialised subject and then a tough general knowledge round. The winner then goes into the next knockout round until that years champion is decided. The specialised subject can be almost anything within reason, but tend to be fairly intellectual e.g. a certain period of history such as the Napoleonic wars, the books of a classic author, or life of a famous historical figure, etc. However you could choose your favourite film franchise or TV series, etc. The winner of each show has to choose a new specialised subject in the next round. The Krypton Factor had a similar knock out format, but you were tested on a variety of things: Your fitness on an assault course, a general knowledge round, a puzzle round, etc. You'd get points for how you placed 1st-4th.

the narrator said that The Crystal Maze is the ultimate British game show, and as much as I love the show and always wanted to be on it as a kid, it really falls second place to... and I IMPLORE you to check this out... KNIGHTMARE A kid was put in a massive sight-blocking helmet, and was guided around chroma-keyed dungeons and dragons inspired environments by four friends, whilst being aided, hindered, or guided by a kinda gamesmaster called Treguard, whose participation really depended on what mood he was in. It really is quite possibly the best game show ever conceived, and nothing like it has ever come before or since. Die I mention your REALLY should go check it out? Else i'll call the goblins on you...

My favourite show is Richard Osman's House of Games (lots of episodes on KZfaq) which is a quiz with four contestants and five rounds every day for a week, every new week there are new contestants. They play for themselves or in pairs, depending on the round and you never know which of the many possible rounds comes up next. The last round is always the same, though, every day. The most points win every day (and the contestant gets a prize) and the most points per week is the week's winner then (and the winner gets a trophy). The questions can be knowing trivia, guessing things, the questions are very different in each round, sometimes even in a foreign language or in code! This is huge fun and because you can stop the video on KZfaq, easy to guess along as a viewer, even as a non-native viewer like me.

There's something quite satisfying about the simplicity of Countdown. You get 9 random letters and have to make the biggest word possible. You get 5 numbers and have to use basic maths functions to get as close to a randomly generated 3-digit number as possible. There is some strategy to how you choose the letters or the numbers, but the actual games themselves are pretty straightforward.

"Call My Bluff" is one of my favourites - Joanna Lumley liked it so much that she persuaded the BBC to revive it, with herself as a team captain.

Our game show were great growing up and there are so many missing off this list. Glad you enjoyed them though.👍

"The Crystal Maze" took over the Channel 4 TV slot of "The Adventure Game", where Anneka Rice (a seemingly ageless TV personality) flew around the UK in a helicopter to find clues, as two people in a TV studio tried to decipher them and direct her. It was filmed as if live in an hour (I'm sure it wasn't, but at least close). Channel 4 was new and innovative. I think it should have been on the list.

the "original' version of Deal or No Deal was from the year 2000 in The Netherlands called Miljoenenjacht en.wikipedia.org/wiki/Miljoenenjacht

We often describe something difficult as being like the krypton factor x

The krypton factor was a show to find Britains superperson, testing mental agility, response, observation, mental ability, physical ability, and general knowledge, Mental agility was solving math equations, response was varying tasks from but the most noticeable were using the airline flight simulators. Goal to land a 747 the best, judged by an airline pilot instructor. Observation was watching a clip of tv program and answering questions about what was shown. Mental ability was solving complex puzzles, and physical ability was running a military assault course in the fastest time. General knowledge was answering general knowledge questions.

The TV show "Who Wants to Be a Millionaire?" was created by British television producer David Briggs, and was first aired in the UK in 1998 on ITV.

Both The Crystal Maze and The Krypton Factor both had short lived US versions. He 1981 US version of Krypton Factor was hosted by Dick Clark.

Crystal maze is the show that started escape rooms because people always wanted to go on the show. I loved it so much. The whole show is you go into room and get locked in and you have to either correctly, guessed the puzzles or correctly, complete the obstacle if you was successful and did it in the timeframe, you got a crystal and could get out if you didn’t think you’d be locked in the room until they either used a crystal to buy you out or just leave him in there for the rest of the show The show has now made a massive one which is in Scotland, where the Public can pay to go in and try and complete the real thing

Deal or No Deal is a British game show, hosted by Noel Edmonds, which aired from 31 October 2005 to 23 December 2016 on Channel 4, and is due to return with Stephen Mulhern in 2023 on ITV.

Congratulations! You Win! the top prize!! WE have Family Fortunes in the UK. It was based on your Family Feud. Still going here after over 40 years.

I used to enjoy Treasure Hunt. A couple in the studio had a large scale map of an area, and a small library of text books that could help them decypher clues to the location of the next clue. They then had to guide a fit young Anneka Rice in a yellow jumpsuit with a camera crew and a helicopter to find the next clue on the ground. There was a fair bit of running and climbing over fences, with lots of views of Anneka's rear end. If they found all the clues in the alloted time, they found and won the treasure.

"Who Wants To Be A Millionaire" and "Britain's Got Talent" (thus 'America's Got Talent') are both UK shows sold around the world! "Deal or No Deal" is from The Netherlands... Just saying!

there were also tons of children's games shows such as Trapped, Jungle Run, Raven. All complete classics and very nostalgic especially Raven. Not to mention Total Wipeout which was for adults but it was addicting to watch and everyone at home believed they could do it.

The crystal maze was my jamm as a child, I loved that show growing up,

0:48 We came up with Millionaire. 😊 And BGT. Wheel of Fortune did air here, but Jeopardy never took off for some reason.

We had Deal or No Deal, maybe 30 years ago! Mastermind fantastic, but stressful too! Gladiators, great characters - Australians loved it! I still watch Pointless most days! Who wants be a Millionaire, probably from Australia or England! Catch Phrase probably not in Australia! Countdown was a music show in Australia, now it's about English and Maths, yes like school! Crystal Maze? Yes, physical challenges are more fun, like Australian Ninja, Holey Moley, Challenge, SAS Australia, Survivor! They didn't mention The Chase? We also have It's Academic, QI, Lego Masters, The Hundred, The Wall, Would I lie to you? Have you been paying attention? It's great to challenge yourself and have a laugh! 😃

I’m shocked they didn’t at least have honourable mentions for the likes of Family Fortunes and The Chase…

14:00 Countdown was one of the first quiz shows to air on the newly created Channel 4 back in the day, it's be going ever since and has had a spin off comedy version - titled "8 out of 10 cats does Countdown"...

It's odd that No.1 is 'The Crystal Maze' because it is not British. This show was based on the French game show, 'Fort Boyard'.

I volunteered on the revival series of The Crystal Maze a few years ago. Bit of an uber-nerd about it. Got a load of merch from the original show, done a lot of blogging about every possible detail I could think of, auditioned for the remake and ended up as a games tester.

Great video as always. The crystal maze now has a place in Manchester where you can take part in the crystal maze games just for fun not TV. Would love to go some day, but my chronic Ill health sadly stops me travelling right now. I used to have a friend Called Greg Scott and he was the warm up man on countdown and the krypton factor.

I enjoyed your enthusiasm to the UK game shows, I grew up with watching most of the shows. If you can react to UK game shows, that would be fantastic 🙂

A lot of TV shows around the world have been off shoots of British game shows and TV series. A lot of other countries don't know about. We only had 4channels for years and years so the content had to be good. Because of this fact I think that's why we had the best of the best with the writers etc. We're still very proud though of our exported shows. It's a shame other countries believe such shows are originally theirs though. I need to do research myself to see which shows actually originated from other places aswell.

Gladiators was originally started in the US but moved into about a dozen different countries, but even the American Gladiators team admitted that UK Gladiators was the best. Probably the reason why both International series were in the UK. If you want to watch. All of the domestic series, the international series and the Ashes series are all on KZfaq.

Deal or No Deal seems to be Dutch "Deal or No Deal is the name of several closely related television game shows, the first of which (launching the format) was the Dutch Miljoenenjacht (Hunt/Chase for Millions)." Wikipeada. It seems that the USA had it several years before the UK.

"contestant ready? Gladiator ready? 3-2-1" (The show is finally coming back after it's been gone for almost half my life)

You should try and find a video about the British gameshow from the 1980s called 3-2-1 that was so bizzare that even the host had no idea what was going on. The premise was to win prizes through solving clues that were so cryptic even The Times crossword clue setters wouldn't be able to solve and most people ended up going home with a dustbin (that's trashcan in America).

Deal or no deal was based on a game from the Netherlands. The British version started in 2005 🇬🇧🇺🇸

Before the video started the board from quiz show Blockbusters was shown. Noel Edmonds hosted Deal or No Deal in England, it is under a new host. Deal Or No Deal launched in Holland first. ITV in Britain came up with Who Wants To Be A Millonaire hosted by Chris Tarrant, Jeremy Clarkson Top Gear (has being cancelled by the BBC due to injury occurring to presenter Freddie Flintoff ex-Cricketer), The Grand Tour and Clarkson’s Farm (the last two will not be renewed by amazon, good news), Clarkson was sacked as presenter of Who Wants To Be A Millonaire. Junior Krpton Factor’s assault course was at the american adventure theme park in Derbyshire, I saw it being filmed once.

Crystal maze is/was amazing. You get locked in if you don't get out quick enough. The team have to buy you back with a crystal they have won. Many a team promise they will come back for team mates and buy them out. Then never do 😂.

Gladiators is my all time favourite show and it's coming back this year!

Catchphrase was originally an American game show that had only one season in 1985 the British version began a year later in 1986.

I can easily come up with another 10, and that being said, I'm not particularly old to remember them so I'm sure the older generations could add some more classics. I know some of these had American versions, not sure which came first but these feel very British even if they're not. Things like: The chase Family fortunes Tipping point Weakest link The price is right Play your cards right Bullseye Fun house Supermarket sweep Eggheads

You should react to some episodes of the shows that interested you. Krypton Factor is top stuff. Crystal maze early years are brilliant.

11:42 - fun fact, before his fame Roy Walker painted my parents house before moving in to TV!

There are episodes of, 'The Generation Game', available to view on KZfaq, from the 70's. It's an interesting glimpse into 70's culture, what with the clothing worn and the mannerisms of members of the public who played the games from the time. Bruce Forsythe was the consummate game show host with the right amount of humour at the expense of the contestants. 'The Crystal Maze', was quite innovative at the time and consisted of a team who had to solve physical puzzles inside a locked room that usually had a theme attached to it, in a certain amount of time. If they managed to solve the puzzle they got the crystal, but more often than not they would choose to exit the room before the time expired, as if they ran out of time they would be locked in and to get them out would cost a crystal. The idea of the game was to get as many crystals as possible with as many team members remaining.

The UK version of Deal or No Deal is like the twelfth version of the show and the UK version predates the US version by only two months.

You definitely need reactions to full episodes of some of these 😄

No, you ninny, "Deal or No Deal" is neither American nor British in origin. It is Dutch.

I think you should do some themed episodes where you focus on some of these specific shows. The greatest hits of catchphrase, the crystal maze, etc… most of which here in the UK are still on television and haven’t been ended. Gladiators is also coming back to the UK later this year.

The funny thing is Deal or no Deal is actually a Dutch show originally I believe, and Who Wants to be a Millionaire is a British show originally, but CatchPhrase was originally American but it was never as popular in the US as it became in the UK.

I used to love The Krypton Factor. It was my favourite game show as a kid in the 80s.

Look for a whole episode on KZfaq for The Crystal Maze! Preferably with the original presenter Richard O"Brian because he's batshit crazy and British eccentricity at it's finest! BTW Richard is the lead actor AND creator of The Rocky Horror Picture Show, so yeah, his brain is about as random as it gets! 😂 The Crystal Maze has four destinations, four separate "themed sets" and they spend just under a quarter of the whole show (one hour total show) in each area. The team is made up of individual public applicants, they don't know each other, so may gel seamlessly, or may not like each other much...but the point is to work as a team. In each of the four zones, are individual rooms with puzzles inside, a mixture of physical tasks, mental tasks, agility etc.... Richard will pick a room, and the team chooses which of them would be best for that particular puzzle. They have a set time to complete it, usually around 2 minutes. The rest of the team can yell out directions, or answers etc...which is sometimes appreciated or sometimes bitterly resented, depending on personalities clashing! 🤣 Each completed puzzle wins a crystal, about the size of a tennis ball, each of those crystals is worth ten seconds. If someone fails to complete a puzzle and doesn't make it back out the door before the time runs out, they get locked into their room. It's up to the team captain, as to whether to buy that person out of their room in exchange for one crystal, or go on and leave them behind. After all four zones are completed, the crystals are added up, a typical average is around 6 crystals in total that they won - a few have won more, some haven't won any! 😂 Richard will first ask if they wish to buy back any locked up players from earlier, if any are still back there, and the captain has to think of what's more useful for the team's final challenge??? Does he want to keep all the crystals for time value or have more hands to help out? So if they have six crystals for example, 6 x 10 seconds = 1 minute. The team has one minute to enter the Crystal Dome. In the dome, huge electric fans are started, and gold and silver "tickets" are blown up all around them. They are like pieces of foil, around a banknote size. The minute countdown begins and the team have to frantically catch as many tickets as they can. The goal, to win, is to catch 100 gold tickets.....not silver! Silver tickets are DEDUCTED from the total of gold!!! That's why the captain has to think, what would be better, leave two people locked up and have 20 seconds more time or have two extra people to help but give up 20 seconds on the timer? If they win or lose, they are each awarded a souvenir crystal in a presentation box ANYWAY, but if they did get more than a 100 gold tickets they would win a prize. Prizes were usually a day's activity, canoeing white rapids or rock climbing up a mountain, with travel and lunch included for the whole team to enjoy. That sort of thing. The overall idea, is teamwork, with strangers who've never met before! There have also been celebrity teams who obviously do know each other, and the gold tickets they collect are worth money for a charity! It's my favourite game show ever! So imaginative, so random, so much fun, it reminded me of the film The Goonies in a way, but better! 😁😁😁

We have Family Feud here, where it's called Family Fortunes. It's had a few hosts over the years but Les Dennis is the classic one! Krypton Factor was certainly avid viewing, even though I knew I'd not be able to be on the show. 🙂 Countdown is a week day afternoon show, which is very popular with those who are at home during that time. There's even been a spin-off version called 8 Out of 10 Cats Does Countdown, where the 8 Out of Cats team does their own comedic version! I'm surprised that there was no mention of University Challenge, one of the classic quiz shows.

I'm glad Crystal Maze made it to the top of that list. That was my favourite as a kid.

There was also a children's one called jungle run in the early-mid 2000s

The Crystal Maze was hosted at first by Richard O'Brien, writer of The Rocky Horror Show.

I loved Crystal Maze with Richard O'Brien in the early 90s. O'Brien is also the creator of The Rocky Horror Picture Show.

Gladiators is the UK adaptation of American Gladiators, but Who Wants to be a Millionaire is definitely a British show.

The Crystal Maze was a great concept. 4 unique zones to play games in - Aztec, Industrial (later Ocean), Medieval and Futuristic. Each zones games were tailored to the style of the zone. Each zone had a unique way of getting in. 4 categories of task - Physical, Mental, Mystery and Skill. The challenges lasted between about 90 seconds and 3 minutes to gain a crystal. If you took too long to get out, you were "locked in" and could only be released by being bought out at the cost of 1 crystal. The end was the Crystal Dome (as seen in the video) which the contestants enter and then wind machines under the floor blew gold and silver slips into the air. The object was to catch as many gold (positive points) and as few silver (negative points) as possible in the time you have, determined by the number of crystals you won (5 seconds per crystal), and put them in the collection point. Win enough gold to win the grand prizes.

it's kinda funny that ideal or no deal was so popular in the us, since when i saw a comment on one of ours from an american, it said "this is a show from the uk? it will never catch on here" (while talking about how horrible it looked). it was a couple of months after that that the us version was revealed.

Crystal maze was my favourite game show as a kid, so good!

American Gladiators started in 1989, and I saw it on UK TV way before our version started in 1992 - I think yours was called "American Gladiators" because the word "gladiators" brings to mind the Roman Empire (for me at least!) Also we do have Family Feud, but it's called Family Fortunes here. Had many hosts, none quite as funny as Steve Harvey though

There was a short lived US version of Mastermind called 2 Minute Drill that lasted from 2000 to 2001

One very recent UK game show that I think is unique and engaging is The 1% Club. Rather than a typical trivia show, it's actually an IQ show, where you have to think outside the box, using logic and reason with the questions being asked and it's usually visual. Anyone of all ages can get involved with the questions and it gets harder and harder as the show progresses; the last question being that only 1% of the U.K. public got the answer right. It really gets the mind working.

Who Wants To Be A Millionaire was invented in England and made at Elstree Studios in Hertfordshire, England, the home of Star Wars and Indiana Jones!!!

Gladiators was mostly copied from the American version, except they created most of the games played, such as slingshot to skytrak to atlaspheres i think. However the British series of gladiators did inspire other countries to create their own gladiators series such as Australia and South Africa

Deal or no Deal came out in 2005. Who wants to be a Millionaire was first aired in 1998, 24 years ago.

I think that "Deal or No Deal" started in the US, but "Gladiators" and "...Millionaire" started in the UK. IMO the best British game shows are the ones where celebrities are the contestants - "Would I Lie to You", "Taskmaster", and "8 out of 10 Cats Does Countdown" (a comedy version of "Countdown") are great. As far as old-style game shows, I half expected "It's a Knockout", "University Challenge", and maybe even "The Golden Shot" in the list.

Family Feud is a spin off of the British game Family Fortunes lol

The Crystal Maze is the ultimate game show 🙏🙏👍

Krypton Factor lead me to gaining my pilots license I’m sure of that now!!

Mastermind allows any specialist subject to be chosen and the producers seek out leading authorities to set questions. The question setters might include university professors, biographers etc. On one memorable occasion the expert approached had to refuse--because he was the contestant! You know you're going to see some tough questions when the acknowledged leading authority... is the contestant! Incidentally, alongside the specialist round the contestant also faces a general knowledge round where we mortals get a chance to know a few answers!
