Okay, here we go. This will be starting sometime this weekend.
Here's how it works. 24 briefcases 24 sums of money, which make up a money tree from €,01 to €2.500.000 in increasing values.

The joker (purple value) is what the beginning of the game is mainly based around.
There are 8 blocks of 24 people. And within these blocks, people are labelled A to X. They are then assigned a random joker case, which will contain a value from €10.000 to €400.000, rounded to the nearest thousand Euro's. A large case comes in with another value in it. This also contains a value from €10.000 to €400.000. A model will open the case to reveal that value. The other 24 will then reveal the value of their cases.

The 4 people whose case values are nearest to the large Joker Prize case, advance to the next round.
At this point, the 4 people are stood in front of a button. A €1.000 sign appears on the screen. That randomly rises each 2 and a half seconds. A player hitting the button means they go home with the value that was on screen. This rises to over €100.000 but can stop at any time. Having the roll stopped means that a question is going to be asked. The first person to buzz in and get the question correct goes through to the actual Deal or No Deal game. The person who gets it wrong leaves and gets nothing.
The game works from normal, and then before the rest of the block return to the podium, the contestant selects a case.

Now, the joker can be won by anyone. Obviously, the player, if they have the joker case. But let's say for example the joker today is valued at €195.000 and it is in Case 23 with contestant X. If the player wins less than €195.000 then contestant X will receive the €195.000. If the player wins more than €195.000 then contestant X won't receive the joker prize.
The game goes on a 6-5-4-3-2-1-1 basis, and Alan Sugar hosts.
Again, I'm not sure when I'm gonna to the first game, but it'll probably be this weekend.
