Bob,
You write
" (If you wanna write-off gaming losses on your
tax returns, ONLY gamble with a slot card. You can receive a
real printout of an actual annual win/loss record that the
IRS HAS to honor) ".

Sounds like you have had some experience with the above. Does anyone know about other Casino's practice of this procedure from a slot card?
In Vegas, the old Frontier use to "Track Your Play" by how much you bought at the change booths. You would fill out a slip, and every time you purchased coins they would mark it down. The only winnings they would count was the hand payoffs over $1200.00 that they gave you a W-2G form for anyway. A couple hours before leaving you would ask for a print out and they would give you a win loss statement that you could file with your taxes. With the advent of the bill changers on the newer machines I do not know how this is handled today or what other Casinos provide this service.
