This is a little game, which is loosely based on a quiz program on the Dutch television.
In this version, the player is presented with 16 panels (suitcases in the TV game).
13 panels hide sums of money, ranging from $1 to $4.000.000. When "opened" (touched) by the player, the hidden sum is displayed and added to the balance of the player.
However, there are three nasty panels within the 16.
One of them (marked "3/4") reduces the actual balance of the user by 25%, another (marked "1/2") reduces the actual balance by half, 50%. In both cases, the player may continue selecting and hitting panels.
The third nasty panel (marked "X") ends the game immediately and leaves the player with a zero balance.
A high-score is kept on file (which revealed a very unexpected bug in sB).
The "Bank", who would pay the balance to the player upon termination, tries to minimize its loss by making an offer to the player after each move.
The Bank does this by making a probablilistic estimate of the remaining profits and losses of the player. If the result is positive, the Bank offers 60% of it (plus the already gained balance) as a pay-off to the player.
Apart from this, the "Bank-offer" is a good indication to the player about his possible additional winnings. If the offer equals his actual balance, the mathematical expectations are minimal or negative.
