I've been playing this game since day one (I think July 2012), and I purchase chips occasionally but not too often. I was trying to keep a running total in my head, and I thought I had spent a total of about $300, but today I added up my total purchases on Facebook and it came to $543. That's more than I would have liked to spend, so from here on out no more purchases. Although I can't complain to much, I estimate I've used over $2,000 in comps. I got both the one night and two night Mirage tower suite, 2 tickets to the follow: Ka, Chris Angel, Zumanity, 5 tickets to Zarkana, one ticket to Love, 9 buffets, $75 FB credit NYNY, picnic by the pool, 2 adventuredome passes, 2 nights at Aria, Gold Lounge bottle service, one night at Luxor, and the 5/50 pizza and beer. I'd say I've got my moneys worth but I'm cutting off all future purchases. I finished every puzzle from the current quest except today, oh well! Also in September 2013 I took advantage of a glitch and bought a few hundred thousand chips for $1.
