There are new slot cards on the Norwegian Cruise ships in 5 levels - Jadek, Pearl, Ruby, Sapphire and Elite all copyright 2016 and manufacturered by Plicards. I have a Jade level but have not been able to get or see any of the higher level cards to get the manufacturer numbers for the guides if anyone can help.

Here's a link to the cruise ship web page with pictures of the cards
