I'll be heading to LV for the 5th time next month and will be trying to pay for mytrip using the coupons in the 2014 ACG. Many of the coupons are for $5 and $10 worth of free slot play, and I was wondering if there are nickel and quarter machines that will return at least 90%, and if you know of specific machines. My bankroll is small (< $100). There's one coupon for 5X points at a place called Suncoast casino. The maximum that can be earned is 100,000 points, and I am wondering how the casino makes money here. Isn't the standard to issue $1 in free play for every 100 points earned? I'd think that it would be worth it to play on machines that hold back less than 5% in this case. Are there machines at this casino that are this loose? Thanks!
