Choose your box, and your first 5

I'll take box 9 and go 1, 4, 5, 20, 19.

KP has selected Box 9.

Round One

1: £100 - another good start, are we going to have another super strong game?
4: £50,000 - perhaps not
5: £5
20: £5,000
19: £100,000 - ack

Not the best starting round ever, and no £100,000 in the box this time. Are we destined for a lower money game?

Banker's offer:

£12,319

Deal or No Deal? Next boxes?

NO DEAL: 13, 12, 22.

Round Two

13: £500
12: £75,000 - oh no, another power five amount hit
22: £35,000 - And another!

Only the £250,000 remaining from the power 5 now, but otherwise a strong block of reds left between £20,000 and £7,500.

The banker feels that was very much his round.

Banker's offer:

£9,724

Enough backup values to turn down a sub-£10k offer in pursuit of a £250k-inflated offer to come. NO DEAL...

8, 18, 6.

Round Three

8: £25,000
18: £10,000
6: £1,000

The banker likes the way this is going, but is still uneasy with the £250,000 still in play!

Banker's offer:

£11,002

£11,000 really isn't bad with so many backups gone already, but £20,000, £15,000 and £7,500 still remain so there's room for a later bailout if needs be. Therefore, NO DEAL.

19, 11, 2.

you've already had 19

Oh so I have. 7.

Round Four

7: £2,000
11: £250,000 - nooooo
2: £250

The board at 8-box now reads:

1p
£10
£50
£750
£3,000
£7,500
£15,000
£20,000

The banker can be heard laughing down the phone...

Banker's offer:

£3,382

Enough stability in that to easily NO DEAL.

9, 14, 15.

box 9 is yours

Oh fail, 10.

Round Five

10: £50
14: £7,500
15: £20,000

Board at 5-box reads

1p
£10
£750
£3,000
£15,000

The banker is loving this game. He reminds you that the 1p/£10 are still in play and suggests you take this very generous bail out.

Banker's offer:

£2,591

Just shy of £19k on the board, so mean's around £3,750. With the 30% chance of an all-blue finish and the 60% chance of a finish on which I'll have a 60% chance of being messed around with, it's a DEAL.

Leave 17 and take the rest in ascending order.

Round Six

3: 1p - Would have been the perfect start
16: £10 - Oh no, surely not?
21: £15,000 - Thank god for that!

Leaving a final two of £750 and £3,000

The banker is annoyed that the £15,000 was found in the final box. If it was the £750 then the game would have been a complete and total victory for the banker, with KP dealing the lowest offer in the game and with the two final boxes both higher in value than the deal! Whichever way it goes, it's been a close one with regards to selling the box under/over it's value.

Banker's offer would've been:

£1,871

KPs box 9 contained £3,000

Box 21 contained £15,000

As for what I'd do...

I'd probably play it the same. A very frustrating game from the player's point of view. The peak offer actually came in round 1! And it just went downhill from there. By the end of round 2 we'd lost 4 of the power 5 but still had the £250k and some good backups. Round 3 then removed a few of those backups. And round 4 then removed the £250k. Round 5 then removed 2 of the highest 3 values.

Looking at the offers I think they were all fair, but I don't think I'd take any of them, with maybe the exception of the 5-box offer.

Of the first 3 offers the first 1 was the most generous as a % of the mean (£12,319/47%). And obviously, the damage to the board pulled that % down to 40%. Once the £250k went the % went up, but the mean was now a lot lower. The 8-box offer was 58% of the mean, but I think given the boards stability at this point it was an easy no deal. And 69% of the mean at 5-box on what could end up with a very nasty finish was I think generous. And the proveout offer was fair enough I think offering a straight averaging (though obviously with a few pounds knocked off lol).

I think also the relative values of the money on offer made it easy to go on. Once the life changing money has been knocked out it's a lot easier to carry on. Multiply every number on the board by 10 and I think the 11-box and 8-box offers recieve a lot more consideration. But when we're only dealing in the thousands it becomes a lot easier to gamble.
