Last time I was in Las Vegas I visited the Hooters Casino because there were big billboards all over town that said "$100 Free Slot Play!".
The hotel / casino is off the strip so its a small drive...we figured it was worth the drive for a deal like that. As you may know most of the big casinos offer free slot play to people who join their individual player clubs for the first time so it seemed like a great deal.
After driving and parking we waited in a big line to get our players club card and were instructed on which slot machines we could "play" our free slot money. Turns out it was only on a small bank of "promotional" machines that you would only win a small amount of money if you hit one of those impossible jackpots. The whole time we were there no one won anything. Just like some other people have posted here it is pretty much false advertising...at least compared to other casinos.
We also got a bunch of random casino coupons...one of them was a match play coupon for blackjack...I put 50 bucks down on a hand of blackjack with the coupon, won the hand and left the hotel with that money in my wallet.
I have not been back.
