The top online casino is the one you win the most money at. There are hundreds of different casinos all over the net. So you have the ability to be picky as well as casino hop just as if you were in Vegas.
Finding the Top Online Casino
Since there are so many online casinos available, you can choose which ones you want to put your money on. That means that you should look at a few features. The first red flag that would make me move on is when a casino requires too much personal information (credit card or social security number). Avoid giving out such knowledge.
The second thing that I would look for is a casino that does not have any dues to pay. There are not that many that make you pay to play. You can always find an online casino that is free. A top online casino would not have to lower itself to having dues.
The last thing to remember is that there are great games at all casinos. The main games are the same, but there are different games that can be more fun. Pick a casino that has games that you like to play with odds that make you happy.
