Crazier Eights: Shahrzad is an expandalone — it can be played as a stand alone game or as an expansion for Crazier Eights: One Thousand & One Nights. It has thirty three new unique cards inspired by Shahrzad’s stories.
Rather than eights, Shahrzad has multicolored cards and split cards.
You can take a look at images of all the cards in Shahrzad here.
Split cards, such as Might & Magic, shown above, are treated like multicolored cards when they are discarded, but you have to choose one side when you play it for the ability.
Shahrzad was a stretch goal for the Kickstarter campaign for Crazier Eights: 1001 Nights. It will be possible to get it as an add-on.
