This week's task is all about the money! £20,000 has been deducted from the prize fund and the housemates are competing to earn it back.

They'll face a variety of different challenges to win back the money for their team.

Some will be about skill

Just look at the concentration on Andrew's Face!

Some will be about speed

Raph isn't wasting any time!

And some will just be completely gross

Are you alright there Tom?

But that's not all!

Big Brother will be tempting housemates with rewards, if they're prepared to pay. 

Who's on the other end of the line?

Are they worth spending the prize money on?

Is that Chanelle's boyfriend?!

He must have been expensive!
