If you want the best chance of making a fortune, you should go to an online casino. The operating costs of online casinos are very low, so virtually all the money you bet is paid out in prizes. Casino-On-Net takes about 2% of bets for operating costs and profit. Britain's National Lottery takes twenty five times as much! In other words, play online and you are twice as likely to become rich.

There are a variety of Intenet sites that take bets. Most of these sites are online casinos, and offer traditional casino games over the Internet. Virtually all the games you could play in a physical casino can now be played over the Internet, at one site or another. The odds are often better, for example a lot of physical casinos only offer roulette with two zeroes ("American" roulette). Most online casinos offer roulette with one zero ("European" roulette) which gives you a much better chance of winning.
When you visit a casino's website, you will find that there are usually two ways of playing. You can download some software, install it on your machine and play that way. Alternatively, you can play through your web browser, without downloading anything. The second option is simpler, but usually gives you access to fewer games.
In addition to these two ways of playing, you can usually choose practice mode or real money mode. In practice mode, you are not risking anything by playing, but of course you can't win any real money either. Practice mode is a good way to familiarise yourself with a game if you are not sure of the rules. (If you want to learn a new game so you can play in an offline casino, this is still a good way of learning.)
