If you want to gamble online, you've probably noticed there are thousands of online casinos! So how do you know which one to pick? Well, it helps to be your own detective. Here are some things you should look for before you register with an online casino:

CUSTOMER SUPPORT: Be wary of any site that only offers an email address or web form for their customer support. Chances are they won't be very responsive if you have a problem. Make sure you can find a phone number and/or live chat support. Give their support a test run with a phone call or chat. Make sure the phone number doesn't simply lead to a voice mail system. Once you contact someone, ask some questions to make sure the staff is competent and knowledgeable.

READ THE FINE PRINT: Most websites have a "terms and conditions" section. Read it closely--no matter how boring it may seem!--to make sure it's fair. Some sites put hidden clauses in their fine print, so check it carefully.

LOOK FOR SEAL OF APPROVAL: The eCommerce and Online Gaming Regulation and Associate (eCOGRA) is a non-profit organization that sets standards for online casinos. Their "Play It Safe" seal of approval means the site has been inspected for its safety, efficiency and honesty. Moreover, an online casino with the seal is also monitored regularly. And, if you have a dispute with the casino, eCOGRA has a dispute regulation service. It's a good idea to look for this seal when researching online casinos.

TEST IT OUT: Most online casinos offer a chance for you to enjoy the experience with "play" money. You don't have to invest any cash, although you don't win money, either. Try a test run to see if you like the casino's set-up and the entire online gambling experience.
