£100,000 prize money reduced to £50,000.
The winner is guaranteed £50,000.

The other £50,000 has been split up into five amounts. I can't remember the exact amounts, but I know the highest was something like £30,000 and the lowest £10. They must decide between themselves whose name will go next to each amount, therefore guaranteeing them that amount when they leave. The winner will also get an extra £50,000 on top of what they got in this twist.

However, if they fail to reach an agreement on who gets each amount before the time is over (they're gonna be timed), the £50,000 will disappear and no one gets it, meaning that while the prize fund will remain £50,000, no one will get the other half.
