Gene, Win Cards have been very popular on various cruise ships that I have been on that sail the Caribbean for 7 days. As best as I can recall many of the passengers would attend gaming lessons just before the casino opens or while the ship is at sea. After the host explains how all of the table games are played you are offered a chance to buy $20 worth of chips for $10 or $15. I have not seen Win Card chips on the boats, but they are likely to exist in generic form. After you are told how much you can win at the different games, the newcomers to a casino begin to play & then find out that the house always has an edge & usually complain that they followed all of the plays on the cards they were sold & now the are losers. The cards do give basic information about the games, but leave out the house advantage. I have some of the cards & a few of the chips.
