Fuzzy Math???

[dave T]

I dont' understand deal or no deal. I watched a few times the first season, and when a player would get down to 2 suitcases (one of which was the one they chose), often the bank offer was an overlay.

Example: $400,000 and 100,000 are left and the bank offers 270,000. How does the bank make money???

At the website, I just played for the first time. I was down to 300,000 and 1,000. The offer was 107,000; not an overlay but still fuzzy math.

Anyone understand how they do it?

Three cases left: $500, 400, and 25 dollars. The bank offers $463. Shouldn't it be about 300???

I've watched the show a dozen times and never could figure it out.
