A few years ago, I was on our LT vacation, always go to Reno. Went to the Grand Sierra casino and saw this weired BJ game, and played. I bought in, I forget how much, and was was given 30 Guaranteed Play chips, chips were marked 2.50 NCV but not real snappers, just had to put up one of the 30 NCV chips on every hand, and play your live 5.00 chips, you could play till all 30 NCV chips were gone.. I only played this stupid game to harvest the NCV chips, but that was impossible, because each player had a number 1 thru 6 on the 30 NCV chips,only 6 players at table, and the dealer and pit boss watched every hand, and they put each players numbered NCV chips in a individual slot in the tray. They had a mark at the 30 count on the tray. So any missing would be easy for them to see. They weren't worried about collectors collecting, but people bringing the NCV chips back into a new game. They only had one table and you could re-buy as many times you want. A really bad game, and I looked at the table for 20 mins. trying to figure out how to harvest, but it was just imposible.
