[6] Catchphrase was presented by Northern Irish comedian Roy Walker from its 1986 premiere until 1999, airing weekly at night.

Mark Curry replaced Weir for the final series, which moved to a daytime slot and ran from 24 June to 19 December 2002.

On 27 August 2012, a revived pilot was made by STV Studios and Digital Rights Group (DRG) with new host Stephen Mulhern.

In the main game, at the start of each standard round, one contestant stopped a randomiser consisting of money amounts by hitting their button.

If a player guessed correctly, he/she would win the predetermined amount and then have a chance to solve the bonus catchphrase.

A correct answer won the contestant the predetermined money amount, plus a chance to solve the bonus catchphrase, which was hidden behind nine squares with the show's logo on each (or random shapes in the Nick Weir/Mark Curry era).

If the end of round klaxon sounds and the bonus catchphrase had yet to be solved in the first half of the game for Roy Walker's later series as well as the Weir/Curry/Mulhern era and just before the commercial break, the panels would be gradually removed until a player buzzed in with an answer.

From series 2, (the Roy Walker era) a new feature which was not seen in the US version, the "Ready Money Round", was introduced.

If the end of round klaxon sounds and the bonus catchphrase had yet to be solved, the panels would be gradually removed until a player buzzed in with an answer.

If neither player guessed correctly, a normal catchphrase would determine who won the bonus bank money.

In 2000, when Nick Weir took over as host, this round was replaced by the "Cash Countdown", in which the amount for each normal catchphrase started at £250 before quickly counting down £1 every .08 of a second.

This round was retained in the Mark Curry series, but renamed the "Catchphrase Countdown" due to the show having abandoned pounds in favour of points.

In the Super Catchphrase, the winning contestant faced a 5 × 5 board of 25 squares, each marked with a letter from A to Y in ascending order.

In the TVS years, if the contestant got five squares in such a way that they made a row or column (horizontally or vertically) on the board, they would win a prize such as a TV or a microwave oven.

However, if they could make a row, column or diagonal through the central "M" square (which Walker often claimed was the most difficult), they would win a holiday somewhere in the world.

Now, in a similar fashion as on Blockbusters, the contestant had to make their way from the left-hand side of the board to the right (in a horizontal line), making adjoining moves and passing on a square meant that they would be blocked and would have to find an alternative path (excluding diagonals).

In the Stephen Mulhern era, there are 15 numbered squares in the form of a pyramid (with 15 at the top) with each row, starting at the bottom, being worth a higher amount of money (£2,500/£5,000/£10,000/£25,000/£50,000).

Number 11 in the middle is starred and correctly answering it awards a bonus prize, which is usually a luxury holiday.

One of the most famous moments in the show's history included a ready money Bonus Catchphrase where the puzzle was uncovered in a way which made Mr. Chips and a snake appear to be performing a sexual act.

[29] On the 2014 Mother's Day celebrity special, one of the Bonus Catchphrases caused a very similar incident to 1994's "Snake Charmer" puzzle.

Like the aforementioned "Snake Charmer" incident, this caused the entire studio to break out in laughter as the picture was revealed in a similar manner.

When he selected the first square, the animation was of a dog's head shaking very vigorously with a large grin on its face and hanging in the air.

This caused the same reaction for the audience of this episode while the contestants and host Stephen Mulhern grimaced at this picture as it was revealed in a very humorous looking way.

The show's theme and incidental music was re-tuned, and was composed by Simon Etchell whose version was used from 1994 to 1999, with some slight alterations made in late 1998.

It was a re-mixed and "jazzed-up" version of the previous theme, composed by Simon Etchell and was used alongside a revamped title sequence followed by a new studio set.

From 2013 onwards, a fourth version was introduced, based on Ed Welch's original theme and composed by Marc Sylvan and Richard Jacques.

[citation needed] A number of board game adaptations of Catchphrase were released over the years.

The format in comparison to the TV show slightly changed and required callers to play from their cars and 'honk' their horns when they knew the catchphrase being described.

Variations of the mascot sometimes appeared in the animations, such as Mr Chips with a lemon for a head (for the catchphrase "Lemonheads" on the episode broadcast on 2 December 1994).

After Nick Weir took over as presenter and the change of graphics, Mr Chips was semi-retired and replaced with the "Catchphrase Family", consisting of a father, mother, son and two other men.
