I'm 4 episodes in (the half-way mark) and I'm mostly enjoying it. There have been a lot of comparisons to The Traitors, which I'm a huge fan of, so it does help to enjoy those sorts of reality gameshows to begin with.
10 pairs of contestants staying in a luxury hotel are given a case. One case contains £250K cash, one contains the dreaded 'early checkout' card, and the others are empty.
Each day the pairs complete a mini challenge to win the opportunity to secretly swap cases with another pair or to simply take a peek inside one.
Then a main challenge determines the order in which all pairs may then choose to either swap or stick with their case at the end of the day. The pair going first has to swap regardless. The objective here is to either ditch the early checkout card if you have it, hold on to your case that you know is empty (for now), or swap for the one you think has the money. Whoever has the early checkout card at the end of the swapping session goes home.
A quarter of a million pounds is a lot of money (a lot more than it needed to be in my opinion), so you really want someone likeable to win it, but there are at least a few pairs of contestants that you would prefer to see go home with nothing. A young lady in a Mother/Daughter pairing was behaving in such a way that her Mum actually had to give her a gentle reminder that she was being filmed.
Over the course of the show friends and enemies emerge, with no-one really knowing who they can or can't trust. In episode 3, it is revealed that whichever pair is holding the cash at the end of each day may now remove £10K from it for keeps, which adds a new incentive to be the one holding the money.
There have been a few uncanny coincidences, that may lead you to believe some behind-the-scenes 'fixing' is going on to increase the drama. Whether it is or not, who will ever know?
Overall, it's 8 episodes of fun, and I'm happy to watch it until the end.
