It's the show about "stars and cars".
Noughts and Crosses with a twist. Inside each box is a celeb and Bob asks a question to them. If the contestant can then say correctly if the celeb got the question correct or wrong then they win that square, some money and have their little symbol implanted within it. If they can get three in row or five in total then they win the round and a mega bonus.
During one round, one of the celebs is holding the mystery holiday. If they pick them, then respond correctly they not only win some money but also win a holiday.
After the break they play for double the cash, and if they fit any more rounds in they redouble each time. When the buzzer goes whoever has the most money goes forward to the Monkhouse Motor Show where they can win a car.
They select one of five at random by prodding a button as the lights flash. Once one has been selected, the player picks one of three categories. Within 30 seconds, the player must then give nine answers out the top 20 given by members of the public.
For every one they get, one the boxes light up. If they light up all nine they win the car. If they don't, they don't.
The format's simplicity, and a certain nostalgia, brought it back on many occasions. ITV's third run began in 2014, hosted by comedy actor Warwick Davis. The rules were the same, the duration was doubled - Celebrity Squares now ran for a full hour. While there were new rounds, such as the personal stories of "Square Essentials", general opinion suggested that the show didn't have enough pace to last a full hour.
The endgame changed slightly: the player is now going for £20,000 cash, which they'll get if they name nine answers in a particular category within 30 seconds.
Two comedians - Tim Vine and Joe Wilkinson - were booked for the whole series. Centre square was taken by an ITV name, such as Bradley Walsh or Keith Lemon. As in all previous versions, the other squares were filled by established comics, rising stars, and general entertainers, so that the show might offer something for everyone.
Usually Willie Rushton or Frank Carson livening up proceedings in the centre square.
(At the beginning of the show): "Hello, celebrities!" and their response: "Hello, Bob!"
"One of our celebrities is sitting in the Secret Square...!"
"Do you agree or disagree?"
"Cross (or zero) gets the square - no money is won!"
"I can imagine where you're going next!"
"Cross cannot get the square - it's game point - if you want a cross in (whoever's) square, you must put it there yourself!"
Based on the US format Hollywood Squares by Merrill Heatter and Bob Quigley (who also created Gambit).

Squares replaced Bob's previous show, The Golden Shot.
Prizes in the first series included holidays to Romania, carpets and washing machines. The 18-foot high game board cost £22,000 to build, which converts to about £160,000 in today's money. The celebrities received £60 for appearing.
The celebrities on the "big box game" on its very first Sunday were: Leslie Crowther (later host of The Price is Right), ample actress Diana Dors, actress Hermoine Gingold, actress Aimi McDonald, comedy actors Alfred Marks and Arthur Mullard, creepy actor Vincent Price, writer and wit Willie Rushton, and broadcasting blarney-master Terry Wogan (later host of Blankety Blank and You Must be Joking).
According to the BBC4 documentary The Secret Life of Bob Monkhouse, nearly all of the 138 episodes from the ATV series were wiped from the station's archives. But Bob Monkhouse saved 40 episodes in his private collection of video cassettes he recorded off-air in the four years of the ATV series.
The 1990s revival dotted about the ITV schedule. The 1993 series was consistent, all episodes were shown at 7pm on Friday night at the start of the year. The 1994 series started in the same slot, but seven episodes were shown on summer Saturday nights abutting Scavengers. The 1995 series moved to summer Friday nights, with about nine episodes held over to the following year.
In 2003, a version by Graham Norton's TV company, So Television, was planned. It was going to be joshingly entitled Soho Squares until the format licensors nixed the idea when they heard what sort of thing goes on in Soho. Originally the revamp was touted at Channel 4, but they passed leaving Channel 5 to cough up the money for a pilot with Tom Binns on hosting duties, as can be seen from the clip below.
Don't look now, it's the Channel 5 pilot.
