The Pechanga casino in Calif. has a new set of slot cards but their website has a mistake in the information provided. There are actually FOUR levels in the new cards (Silver, Gold, Platinum and Red) although a few places they indicate there are FIVE levels. Here's a link to their website with more information on the cards...

I just dropped them a note regarding the mistake so it may be corrected sometime soon
