Picked this up to be an Xmas present, and discovered as I was wrapping it that the seal was broken. So I took a look inside to make sure all the bits were there. The only thing obviously missing is a rule book. Are the rules printed on one or more cards with the black back that I see in one of the video reviews? Or am I missing a rulebook?
The rules aren't all that terribly complicated - there is a BGG YouTube video describing the game you could refer the giftee to.
I also found a few copies of the rules in pdf out on the interwebs after a quick Google search, but I'm not sure of the copyright so would rather not post a link here - if you want you could do your own search and print out a copy. The old "Alea" version and the new edition are the same rule-wise.
This is a great gift, hope the recipient enjoys it!
