can anyone tell me how the roulette tables were set up at Harrah's Reno/Tahoe around the 70's I have atleast 5 yellow HC chips with different color inlays white, pink, red, blue ect. But I also have 4 different chips with blue inlays that match, but different color chips. were the tables set up by chip color, ( yellow table with different inlay) or were they set up by inlay color ( blue inlay table with different color chips) what distinguished one player from next inly color or chip color?
