The Super Case is an endgame feature introduced in 2004 where an extra large prop case is revealed containing an extra cash value between 50 cents and $50,000, or up to $30,000 on Double Deal Friday.
Not sure exactly what amounts between those values could show up in the case.
The UK version is so different in terms of style and pace to the Australian version (assuming they’ve kept the previous format used there), that I genuinely think it could do more harm than good.
I think the that’s how it worked …while the early years had early rounds to determine who would play, eventually it would be that one sections of the audience was randomly picked per episode, with one of that section being picked to be the main player, with the others holding a cases (guessing what they hold inside case to win).
(I’d guess they did multiple episodes a day with the same audience too).
From memory, they had six ‘blocks’ of audience and one block was selected each episode, with one person being the contestant and the others holding the cases. Perhaps they filmed six episodes at a time.
