If you're anything like me, you don't have a whole hell of a lot of money to blow at the casino, but if I do go to the casino, I will mosey on by some slot machines - yep, the one-arm banditos. Last time I gambled, up at Mohegan Sun, I played some nickel slots as well as some penny slots, and even came out on top a few bucks.
Online, there are so many sites to try, but Poker Sites USA is one of the best to search for the one that fits your needs and wants. It's got links to Sportsbooks, Texas Hold 'Em, slots - anything you can imagine.
Then there's Online Casinos for USA Players. A lot of the sportsbooks are located overseas, and that isn't really an issue as far as payouts go, but the challenge is always finding a good site that is trusted, to use. Me, fantasy football is my landlocked vice. I play for no money, but it's still pretty fun.
Best US Poker Sites is also a good one - right off the home page you can get to a sportsbook (BoDog), a poker site (Carbon Poker), and a virtual casino (Broadway Tables). They say variety is the spice of life, then this site must be said spice.
Soooooo, in closing, if you're looking for a good site to gamble with - and right now, football season is starting so I'm sure people are looking for ways to bet on games - check out the three sites above. They are all legit and give you plenty of options.
Good luck and happy winnings!
