The problem, of course, is that one normally wants to consult the entire deck rather than deciding in advance whether you want Trumps or Minors. Unless you want to resort to using D&D dice (there are 78 possible rolls of 2d12), it's not obvious how to do that with dice.
I think I've finally come up with a workable method. You have to take into account not only the numbers rolled but the relative position of the three dice. Two dice are considered to be "linked" if they are touching, or if the space between them is narrower than the width of a die; if they are separated by one die-width or more, they are considered to be "unlinked." This allows for four possible patterns of throws, taking their names from Morse code for lack of anything better to call them:
The four patterns are:
- O-pattern (three links): All three dice are very close together. Minor Arcana.
- M-pattern (two links): One die is close to each of the other two, but the other two are not close together. Minor Arcana.
- T-pattern (one link): Two dice are close together, and the third is isolated.The Trump corresponding to the two linked dice, ignoring the third.
- S-pattern (no links): Each die is far from the others. Minor Arcana.
As before, you get the Fool if something unexpected happens, like one of the dice falling out of the dish or something. (I considered making the S-pattern the Fool, but that pattern occurs too frequently to make that viable.)
Further details of the layout of the dice could be used to add interpretive nuance. If it's a Minor, the O-pattern might indicate a stronger or more concentrated influence, while the S-pattern is weaker and more diffuse. In an M-pattern, one of the three dice is "central" and thus more prominent than the other two. For a Trump (T-pattern), the number on the third, isolated die can be taken into account.
