Heh. I decided that for my my Caching exchanges, I would provide 6 dice (not as cool as Chessex dice, love them) and the instructions to a game called Farkle that is great family game.

Maybe after enough time I might get some custom dice going but not now.
Already have a ton of Chessex dice for my Farkle games. Getting Chessex dice can be addicting!
