The TV show on NBC in the USA running this week during primetime (Deal
or No Deal). I figure there are roughly 10, maybe 15 contestants. They
pick a briefcase that has between 1 penny and 1 million bucks and then
play this silly game where NBC tries to buy the briefcase from them
while amounts of money are taken away from the list of possibilities.
The contestant's hope is that they've picked a briefcase with a lot of
money and that when an amount is removed from the list that it is small
amount of money not a large amount (I categorize a large amount to be
more than 100,000)

NBC tries to give the least amount of money possible away. The
contestants try to get the most.

100,000 or above unless you're already rich ;)
