This one's a corker, because we're dealing with someone who knows what it's REALLY like to play this game... yes, it's "moderator H" aka DAVID!

Just like everyone else, he starts with this configuration...

...and then it all changes thanks to the Dulux Purpliser! There are 11 red boxes here with all the red amounts, 11 blue boxes here with all the blues, and 11 greens with percentages from 0% to 50%. Whatever green you find is the share of the red that gets moved to the blue.

We do that five times in all. For each application of that Dulux Purpliser, we need a red, blue, and green box selection - a different one each time. Are you ready?

Yes! Here we go...

Pick 1: 2, 3, 1

Pick 2: 3, 10, 9

Pick 3: 7, 2, 4

Pick 4: 5, 6, 11

Pick 5: 11, 4, 5

Starting things off with red 2... £250,000! Oh my goodness, this could be interesting... the blue that's in line for transformation is £10... but this is the huge moment, how much of the jackpot is being redistributed? Answer... 35%! Your new top prize is £162,500, but your board now also contains £87,510!

Well, that was some start. Next one is red 3... £50,000, so this could be an impact-maker too... blue 10 is £5... and green 9 is 45%! Another big squeeze, to leave you with £27,500 and £22,505 boxes!

We go to red 7 now... that's a bitlot quieter, £1,000. Blue 2, though, is the 1p! So at least that's going up, unless green 4 is the 0%... but no, it's the 50%! That leaves you with the amusing combination of a red £500, the standard blue £500 (for now), and a blue £500.01!

To the fourth pick. Red 5 is... £75,000, another big one! Blue 6 is £750, the highest blue... and green 11 is 40%! You really are giving this board a shake, as you've hit the four highest percentages and three of them have affected big reds... £45,000 and £30,750 are now on this board!

Final pick... £5,000 is the donor... £1 on the receciving end... just the 15% this time, giving you £4,250 and £751 boxes.

This board really is one to look at for a while so it sinks in...

You have Box 22 assigned to you... and we're ready to go! Five in the opening round... this could be fascinating!

Wow, that's some board!

17, 11, 16, 4 and 14 to start, please!

Wow. Getting ready for an epic game.

Right now, your box has a 5/11 chance of containing at least £20,000.

Of course, that also means each box you pick has that same chance. How will this one evolve? Let's find out...

Box 17... £4,250. That'll do nicely to start here.

Box 11... £3,000, another disposable red.

Box 16... £100! That's three excellent boxes... unfortunately, the opening round has more than three boxes to select.

Box 4... 50p! But that one is even better than the first three! We're heading for perhaps the best opening offer to date in this series...

Box 14... 10p! Oh, WHAT A START!

The Banker says that this is highly unnerving, but he always tries to restrain himself at the opening offer, and he's not stopping now...

This first prediction is always highly important. How high do you think he's dared to go?

Yes, a great start!

PLAYER'S PREDICTION

£15,000

It's big... it's his biggest opening offer to date...

BANKER'S OFFER

£12,500

...but it's not quite that big. 20% error margin there, meaning that there's no improvement to Box 23, but no degradation either:

That's not too bad.

Next 3 please:

13, 9 and 1.

Box 13... £500! Oh, this keeps getting better...

Box 9... £751! What a board this is - you only have four amounts left lower than £10,000!

Box 1... £27,500. Took long enough to find one of those!

The Banker is very worried indeed, as you can imagine... what is your prediction now? This will decide the added cash amount.

You can't argue with that! Just 2.56% out...

It certainly is chunky... but...

NO DEAL

Next 3 please:

18, 2 and 15.

Box 18... £10,000. Amazingly, your fifth-lowest amount...!

Box 2... £162,500! Oh, it was going too well. But that's the power of the Dulux Purpliser - you didn't actually lose all of the £250k, there's a massive chunk tied up in another box!

Box 15... £30,750.

Not the best round but not a disaster either...

PLAYER'S PREDICTION

£15,000

Certainly not a disaster...

BANKER'S OFFER

£19,500

...not even enough to make the Banker reduce his offer!

That prediction might be a disaster, as it's a 23% miss and takes out the 200%...

Next 3:

21, 19 and 8 please.

Box 21... £100,000! Maybe this will be the round that sends the offer down...

Box 19... £500.01! Or maybe it won't...

It's tempting but I'm going to carry on. Still got five above the £19,500.
