The only requirement is that you must use all six different
dice values plus one blank die in each of the three disks. But
how you distribute them is entirely up to you. You're going to
see that the method of distribution makes a great deal of
difference to your gambling success.
For instance, don't use this arrangement:
(0,1,2,3,4,5,6) (0,1,2,3,4,5,6) (0,6,4,2,5,3,1)
because it cannot produce any 7/11 winners or SuperJackpots.
With this arrangement, the expected value of the game is minus
$1 - you lose a dollar every time. However, other
arrangements can produce games with a positive expected
value. That means you can make unlimited amounts of money if you
stay at it long enough!
