If a viewer answers the current question correctly, they will win a guaranteed sum of money (usually £500) and get a chance at unlocking The Mint by guessing a 3-digit pin code.
Questions involve on-screen words that fit into a particular category (often celebrities' names) with the vowels missing.
The answers are made even easier to find due to the presenters also giving out clues as to who or what the question refers.
These are similar to other phone-in quiz shows' ladder/tower games where viewers must come up with answers to fit into a specific category, for example, 'Name sitcoms' or 'Name famous blond(e)s'.
The ladder games usually happen during the time that a special guest is being interviewed on the sofa.
This game also involves a group of 5 live contestants that differ each night (for example, 5 male lifeguards or 5 hairdressers).
It was reported by Beverley French that Dowling Island is currently closed for renovation over the winter period.
Due to the problem this caused, the presenters give out clues at specified intervals and contestants are now only asked guess what they think the item is.
When contestants make a mismatch the two panels are turned back around; future callers must memorise their positions.
If the contestant manages to reveal the 2 golden pictures, they win the top prize of £2000 (and a chance at opening The Mint) and the game ends.
At a determined interval in the show, a winning contestant will be given the choice between attempting to guess the 4-digit code that unlocks The Mint, or playing 'Instant Cash'.
The aim is to choose tea pot lids that spell out The Mint in order to win the prize amount of £5000.
The glass has marked levels on the side and depending on how high up the liquid comes, the contestant wins varying sums of money.
If they get it right an envelope (that is present on-screen throughout the entire game to prove there was no underhand trickery) containing the answer is opened and shown to the viewer.
The £36,000 winner made an appearance on the show on the night of 5 October and drank champagne with Beverley French.
