I am trying to find a description/rules to a game that I believe is called Dragon Dice.

Details I remember are:
- Uses 8 dice
- 3 of a kind of a number wins
- 6 of a kind of a number wins more

That's about it. I'm not sure if players bet on individual numbers, hoping for trips+ of that number, or just looking for any 3 or more of a kind.

Anyone have any webpages or information on this, or a similar game?

Nice find! That's the game.

When I did a search on "Grasping Eight", I also found a book - Board and Table Games from Many Civilizations, by Robert Charles Bell. It confirmed my suspicion that a 3, 4 or 5 of a kind is an 8x winner, not just an exact 3 of a kind.

I may do a self-analysis of the odds and HE, unless someone can whip it up quick as a mental agility exercise.
I also thought, with 8 dice, what are the odds one would roll at least one of each digit?

You can do this and show your results when completed.
8d6,
8 dice... that makes for many possible outcomes (6^8) = 1,679,616
but just 1287 unique combinations
(11112222 and 22221111 counting as the same combination)

Here is a little help.

191,520 / 1,679,616 = 11.4026063%
I'm too cold and tired to show my work, (and lazy too)

so here is a site that shows how to do this, if you want to learn how, it is quite easy once you see how.

http://blog.plover.com/math/yahtzee.html

and at the bottom of the page it even has a calculator to do the work for you.
That way, you can check your math
Cool!

Alright, so I looked over the figures (thanks, 7craps!), and I am trying to wrap my brain around it. Granted, this is an "ancient" game, most likely before mathematical analysis. I am finding this to be a positive expectation game for the player. Even if wins are paid for 1 instead of to 1, the player will win in the long run.

I wonder if this game were reworked with some more exotic bets, could it be a fun carnival game? Not necessarily for a casino, but for charity events or "Monte Carlo" nights.
