yes but they are the worst slot machines in all of Vegas. Stay away. The "house edge" on these machines are more than twice that of the already rip off machines in the hotels.

I agree it is almost impossible to win on the slots in the airports. Plus you will have way more fun inside a casino

let's be truthful. People don't go to Vegas and win. So yes there are slots in the airport and you are as likely to hit it big on one of those as you are in any casino. If the casino's paid out they wouldn't be in business. Always remember its the thrill of trying to beat the odds, not winning them.
