Here is a little update from Ted Gottieb of Gaming International. They distribute Win Cards. The list is not necessarily complete but a good guide. He also tells me a change in accounting procedures authorized by Nevada Gaming will make Win Cards more attractive to casinos. There could be as many as 12 more casinos signing up to use them this summer. Gaming has said the casinos can assign a value to them. This allows auditors to zero out the loses instead of counting them as loses. If you have ever dealt with a bean counter, you will understand the value of this procedure.

Current casinos using Win Card Chips:
Flamingo Hilton - Reno
Rail City - Sparks
Casino Niagara - Canada
San Juan Marriott - PR
Wyndam - Aruba

Obsolete Win Card chips:
Dunes, Hacienda, Sands, Riverside, Reno Ramada, Tahoe Biltmore, High Sierra, The Carib Hilton PR, Sands PR, Hyatt PR. Boulder Station. There have been about a dozen others. The open casinos might have the chips. Its worth asking about.
