Basically, there are 6 people (one of them happened to be Series 62 contestant, Dominic Travers) at the start of this floor, at the other end is a laser beam which they cross once 30 questions have been answered correctly. If they answer together as a team, they get £100 for the pot, but if someone wants to "breakaway", it's worth £300 per right answer, but the person can only ask by themselves, although they can offer one person the chance to come across, but the downside is that if they get a question wrong, they're eliminated from the show. The person that is invited can decline to come across too.
The first 21 questions are split into 7 categories of 3 questions. The first one is chosen by Nick, the next ones are chosen by the person who wins a "life", or the "breakaway" player. After every 3 questions (or 1 category even), if one person isn't already across, the team are asked if they want to "breakaway", and have 5 seconds to say so. Incidentally, at these points, there is also the change to gain a "life", so that if you get one wrong when you're on your own, you just lose the life, but if you have none left, you go. If you get one wrong as a team, all you do is lose the money that is banked upto that point.
