I mentioned briefly in one of the previous blog entries about different styles of playing cards in other countries. You can see pictures of them at
The Spanish deck is 48 cards, but traditionally the 8’s and 9’s are left out to make a 40-card deck. The German deck is 36 cards, but traditionally the aces are left out to make a 32-card deck. This all sounds a bit arbitrary, but think of all the arbitrary rules in card games that you’re used to playing!
