There is a lot of speculation about this on the net ( check http://nslog.com/2005/12/20/deal_or_no_deal_algorithm/ for instance ). It *is* a function of the average of the remaining amounts. A person has suggested the following formula
banker's offer = average value * turn number / 10

On the programme i've found a very good rule of thumb is to add up all the money left to win, divide by the number of boxes left to get the average amount the person is going to win, then the banker will consistently offer around 15% less than that figure. Try it yourself.

It changes as the contestant has fewer cases left. Take the average of the amounts left - this is the "expected value" of what's in the case. At the beginning, the banker offers about half of that. As there are fewer cases, he offers more and more of it, up to a little less than the expected vallue. On average, if you figure he'll offer about 2/3 of the expected value, you'll be pretty close.

Isn't it just an average of all of the amounts left? I've never done the math, but I assumed that was it. The banker himself doesn't make any actual decisions; he's just a symbol.

Apparently, for the NBC Version online, the formula is based on the average of the "big" numbers and the average of the "small" numbers as follows: “Big” $ values are $100,000+ All others are “small” $ values. In the formulas below "big" represents the sum of the remaining "big" dollar amounts. "Small" represents the sum of the remaining "small" dollar amounts. EV is the "expected value" of the remaining dollar amounts. (Sum of all the dollar values divided by the number of remaining values) When there are 20 cases left the offer is .0077*big + .07*small. (.154 * EV of big + 1.4 * EV of small) When there are 15 cases left the offer is .0144*big + .09*small (.216 * EV of big + 1.35 * EV of small) When there are 11 cases left the offer is .0273*big + .13*small (.3003 * EV of big + 1.43 * EV of small) When there are 8 cases left the offer is .0442*big + .17*small (.3536 * EV of big + 1.36 * EV of small) When there are 6 cases left the offer is .062*big + .2*small (.372 * EV of big + 1.2 * EV of small) When there are 5 cases left the offer is .1025*big + .25*small (.5125 * EV of big + 1.25 * EV of small) When there are 4 cases left the offer is .1683*big + .33*small (.6732 * EV of big + 1.32 * EV of small) When there are 3 cases left the offer is .305*big + .5*small (.915 * EV of big + 1.5 * EV of small) When there are 2 cases left the offer is .355*big + .5*small (.71 * EV of big + EV of small)
