I've got the 36 colored but not 36 unicolored. Can you play any of them without using the second 36?
Yes! There are three of the six games playable without the black dice. Look at the rules for SIX D "two", SIX D "five", and SIX D "six". I actually mean to amend the rules for "six" to include the black dice, but as they're posted online, it doesn't use 'em.
Thanks for your interest, and I'd love to hear any feedback you have about any of the games.
