Chris Cooper (on MSN again ) has decided to no deal!

His next 3 box choices are boxes 3, 7 and 19.

Box 3 contains: 50p!! Another blue has gone! 2 more good boxes and were loojing at an awesome sum of money from the banker!
Box 7 contains: £500!! This is shaping up to be an awesome round! One more blue!

The game board shapes up like this:
