The twist:

There are a selection of "power ups". At the beginning of each round the player must choose whether he wants a "normal" or "super" power up. There are also associated "power downs". There are 3 normal power ups, and 4 super power ups. They are as follows:

Normal Power Ups
===============
80% mean offer
Offer after every box for next round
Blue Up - lowest remaining blue has 0s added until it becomes red

Normal Power Downs
=================
33% mean offer
Banker looks in box (swap will be offered at end)
Red Down - lowest remaining red has a 0 removed

Super Power Ups
==============
£250,000 extra life - if the £250,000 is discovered then it will be readded to the game and all remaining boxes (including the players) are reshuffled
100% mean offer for next offer
Red Up - lowest remaining red has a 0 added
Redo Round - player has option of redoing and future rounds. Can only be used once. All boxes, including the players, will be reshuffled.

Super Power Downs
================
£250,000 removal - If the player's box contains £250,000 then all boxes remaining in the game will be reshuffled. If it is not in the player's box then nothing happens. The player is not told if a shuffle has taken place.
1p club - All remaining blues are converted to 1p.
Red Down 2 - Highest remaining red has a 0 removed
No All Blue! - if in any future round the player has an all blue round then the round will be repeated and all remaining boxes (including the player's) reshuffled. Will only be used once.

So, whichever type of powerup you choose you have a 50/50 chance on whether it will be good or bad. Each power up in a group has an equal chance of being selected.

You choose a powerup at the beginning of a round.

So, to start:

1) Choose your box!
2) Choose which type of power up
3) Choose your first 5 boxes

And good luck!

I'll pick Box 4, and start with a super power up, to mix things up right away.

1, 3, 6, 10, 15.

Red Up!

£1,000 becomes £10,000.

Round One

1: £25,000
3: £100,000 - oh no
6: £35,000 - all red...
10: £20,000 - still all red...
15: £250,000 - and it finishes at all red in cruel fashion

The banker is glad you didn't get the redo round power up!

Banker's offer:

£6,057

Deal or no Deal? Normal/Super. Next boxes.

*sigh*

No Deal, normal one this time, and I'll go 21, 22, 20.

80% mean offer

Round Two

21: £100
22: £500
20: £50

Gah, says the banker!

Banker's offer:

£10,200

It's still tempting to play on, but because I can't bring £250,000 into play the incentive to play a Super power-up is greatly reduced, as indeed is the potential in general. Therefore, DEAL!

Normal power this time, and I'll go 18, 16, 14.

And a second offer deal!!! Let's see how it'd have gone...

Red Down
£2,000 becomes £200.

Round Three
18: 1p - ack
16: £5 - oh my
14: £10,000

11-box board

£5,000
£7,500
£15,000
£50,000
£75,000

A good round all things considered. The offer would certainly have increased had it not been for the 80% offer last time.

Banker's offer would've been:

£8,997

Well, I recognised the 80% had to be taken... the stability would probably have pushed me on here but only just.

Would again have gone for normal power up; 12, 8, 2.

Round Four

12: £10

2: £50,000

Board at 8-box:

£250

£5,000
£7,500
£15,000
£75,000

The banker has looked in your box! He says it contains a red value. He's telling the truth, and as proof he will guarantee that you will recieve a bonus £5,000 at the end of the game if he is lying!

Banker's offer:

Banker's Gamble

Oh now that's brilliant.

I think it's a four-figure amount. However, it's under 70% of the mean, there's no utter disaster scenario if I go with a normal power up, and if I Wakey it then the only way I can't win at least £3,000 is if it's powered down. DEAL.

Normal power up (not risking turning £75,000 into another £7,500). 5, 7, 9.

And we're back in live play...

80% mean offer!

Round Five

5: £750
7: £75,000
9: £5,000

The banker has no choice with the offer

£5,720

Bah.

This is going to be all kinds of irony if I regret undealing that offer... No Deal, I can afford to gamble on a Super power up for a potential £30,000 box or a do-over if I need it, and I'm going to go 11, 13, 19 - leaving 17 to the end.

100% mean offer

Round Six

11: £250
13: £3,000
19: £7,500

Leaving us:

£10,000
£15,000

Banker's offer:

£12,500 - If you no deal then you get the SWAP if you wish

What's it to be?

DEAL. Never mind the fact it's a coinflip gamble, losing means I go below what I dealt at 14-box!! I chose my own box so I wouldn't have swapped, the swap is so I have control over my box

The banker points out he only offered the swap because he was allowed to look in the box. You wouldn't have got it otherwise!

KP's box 4 contains £10,000.

Box 17 contains the £15,000

So all in all that's an OPW I think?

It certainly is! Incidentally, I propose this game is called "Power Deal" (origin: Daniel of third-offer-OPW fame in describing a 95%-of-the-mean offer).

I like the name "power deal"

If anyone else wants a game then let me know!

It's a decent game...well done anyways!

Could I have a game please??

Can I claim copyright on that?
