my offers from CET usually include freeplay for machines or chips for the tables. I have always opted for the freeplay. I received a seperate offer to use anytime between now and June at Tahoe in addition to freeplay that is 250 in promo chips. I am not so sure I understand their use. If your sitting at a 10 black jack table do you use 10 in chips and if you win you get to keep regular chips? or do you have to put 10 of your own money with the chip and then get 20 if you win?
