Nine Boxes Problem

There are 9 boxes. Within each box is a cash prize. The maximum cash prize is unknown, but you can safely assume that the minimum cash prize is $0. Your goal is to obtain the highest prize possible.

Instructions: 

1. Click on any of the box to open it. The prize in the box will be revealed to you.

2. Upon opening the box, you have to decide if you want the prize inside or not. 

   • To accept the prize, click on 'Take Prize'.

   • To reject the prize and open another box, just click on any of the unopen boxes. 

3. Note that you will not be allowed to accept any prize that you have previously rejected (i.e., no backtracking).
