The rules are simple. There are 24 boxes - the standard UK 22 plus £25k and £150k. They're pre-randomised into green, grey, and gold. You open boxes one at a time, and once you get to five or two left on one colour board, you get an offer. If you turn them both down, once you reveal the penultimate box on that board, you win the last one standing.

You can only win from two boards, so there's serious strategy!

I think it's safe to say you'll want to win on gold here:
£5
£100
£250
£750
£5,000
£10,000
£15,000
£25,000

You don't pick your own box. Pick three to open now - you won't get an offer sooner than that.

I am supposed to be doing a lab report on copper sulphate and of one of those weird chemistry machines that does something I don't actually know.

But DEAL OR NO DEAL!

My first three are 20, 12 and 23.

20 - £35,000. Weirdly, I'd call that brilliant! It's a hit on the gold board, which you need to get an offer on, and it's below the median on it!
12 - £250. That's arguably the right number on one of the weaker boards.
23 - £1,000! That's EPIC! Oh my goodness, this gold board is unbelievable!

I'll ask you to open another two boxes now, but if either's gold I'll stop you right there.

I shall pick... 1 and 21.

1 - £500. So some hope of building on the gold position on the grey board too.
21 - £3,000. All the peanuts amounts are still there on that board, but so are £20k and £50k...

Pick one more. Unless it's green, we'll get an offer.

Did someone say peanuts?

My next box shall be 8!

8 - £100! It's green, we need one more before an offer, and it could be a good one...

I'll pick number 16 now.

13 - £750! Wow!

£5
£5,000
£10,000
£15,000
£25,000


Bearing in mind that if you deal on this board now, you can only win on one other board...

Banker's offer:

£9,001

What is it with you and £9,001??

I'll no deal this one.

Pick another box, you might get another offer!

KP... I got too engrossed on my lab report XD

I've finished it now, it was surprisingly simple.
Now I've got a data analysis assignment which is a huge pile of *beep*.

3 please!

Hopefully these numbers and this analysis will be far better fun.

3 - £50,000! Possibly not, but remember you don't have to take anything from this board - you can take money from any two others. So what you have to hope now, it seems, is to take money from green and gold before this one can weigh you down.

10p

£50
£20,000

Banker's offer:

£3,000

No Deal, KP

One more to pick whenever you're around.

Four!

4 - £75,000! Wakey up, you've got an unbelievable decision to make here!!

£1
£10
£100,000
£150,000
£250,000


Remember, you can only deal on two boards. You could leave those big gold numbers to last and be forced to take money from the other two boards, leaving this one isolated!

Banker's offer:

£50,000

OK... I think my lab report was over... 3 days ago

I think I can go on another round, so NO DEAL, and I will pick box 19 for my next box.

19 - £15,000. Not what we wanted, to hit a green. We want to see golds so you can be sure of getting money from that board, obviously keeping at least one of those huge ones to two-box...

Two more to open, as you won't get an offer before then.

You'll hate me for this...

What boxes do I have left?
