There are 26 cases, each containing a dollar amount from $0.01 to $1,000,000.

To start, you must select a case which will remain unopened throughout the game. The game requires you to select a certain amount of cases each round until only two cases remain (one being the case you selected first).

After each round, a banker will make you an offer which corresponds to the dollar amounts available. You may choose to accept the offer and take the money or decline the offer to open the remaining cases. If you choose to decline on the final round, you will win the contents in your original case.
