Tonight is the night of the seventh live challenge.

The task this week takes the form of a game of bingo. One housemate must play the role of the caller and he or she is unable to win the challenge.

As usual there is a twist, the twist this week is that there is only one winner and that winner gets to choose one person to enter the reward room with them. The challenge is a maximum of six minutes long, if no-one has shouted house it is the housemate with the most numbers that wins.

Inside the reward room they will spend the night together although the exact arrangements have not yet been announced.

The rules are as follows:-

  • The caller may only draw one ball out at a time.
  • The caller may only draw a ball each time when prompted by the bell.
  • Housemates may only cross off a number when the ball has been drawn from the machine and announced by the bingo caller.
  • Housemates may only shout ‘House’ if they have crossed off all the numbers on their board.
  • Tonight’s challenge is not optional. All rules relating to tonight’s challenge must be adhered to. Failure to do so may result in automatic failure for the whole group.

Update

What to Read Next

Big Brother has now announced the contents of the reward room. The room will be themed on a luxury hotel bedroom. It will contain a double bed, hotel room furniture, champagne on ice, a room service menu and a plasma screen television with a choice of DVDs for the pair to watch. The room will have a 'girlie theme.

In addition, there will be a second chance for all housemates to get a chance to enter the room. In a very E4 move, tomorrow is 'Second Chance Sunday' and another game of bingo will be played for the reward of the room tomorrow night. The Sunday night room will be different however, having more of a 'boy' theme.

No, "one little duck" is not rhyming slang ...
