Just played this the other day - and my partner and I have a couple clarifying questions, if that's ok!
1) Can you Diamond Jack a Spade Jack - making the 'shield' worth 20 points? We figured as such but want to check.
2) Kings and Queens are worth 40, do the also cost 40 to purchase, or do they cost 10? I believe they cost and are worth 40, but my partner wasn't 100% as neither of us were able to purchase any Kings or Queens.
Thank you for the fun game, I'm going to show it to my mom as a way to play 'something like Dominion' when she goes camping :)
