Legal online casino gambling is continuing to explode across the country–but is still only legal in 6 of the 50 US States. These are the states where online casino gaming is legal:

Since going online, the gaming sector has flourished–and the continued growth of legal and licensed online casinos only makes its foundation stronger. Even though online casino gaming is only legal in six states, there are hundreds of legal online casinos on the market–so things may be a bit overwhelming. If you find yourself lost in online casino sauce, then don’t worry–you can check out our list of the best online casinos.

Each casino offers a different promo code (such as risk-free days, free chips, or deposit bonuses) so I would sort through our promotional offerings page before you make your decision as to which casino you want to play with.

Once you’ve made your choice, you’ll be introduced to the world of online casino gaming. If you thought the online casino choice was overwhelming, then you’re in for a treat once you actually register for it. You’ll notice immediately you’ll have a ton of games to choose from–just like you would if you were at a brick-and-mortar casino.

Here in this story, I’ll go through the most popular options available on most online casinos, and which individual online casinos are the best in that field!

Most Popular Online Casino Games


Slots are the creme-de-la-creme of online casinos. Each online casino on the market has dozens of slot games available to its users, each one making up a majority of the playtime for each of these online casinos. Slots machines are a big draw for players, and give you the opportunity to hit some jackpots and bonuses that can make your head spin.

Every online casino on the market offers slot machines to some extent, but some of the best to do it are:


The ultimate game of chance (that fools like me think they have some control over). Roulette translates so well into the online casino world, and is enjoyed by a large number of players. When you play online Roulette, it actually works similarly to an online slot machine (random number generators with just a different skin).

In addition to video roulette, many online casinos offer live roulette–a live stream of a real roulette table. So, if you don’t trust the video version of casino games, then these live tables are just for you. Here are the best online Roulette gaming providers on the market:


When we’re talking cards, Blackjack is the best game out there. While there really is no skill involved in Roulette, you can make some real arguments that blackjack is really all skill–at least once the cards are dealt. Because of that, blackjack is one of the most popular online casino games on the market.

Similar to roulette, blackjack has a live dealer option–a live stream of a blackjack table with a real dealer, dealing real cards. If this fancies your interest, then I would check out these online casinos:


While we’re talking about cards, it's hard to ignore the oldest card game on the market–poker. Online poker is nothing new, so I won’t bore you with the details. But, before I give you the best online casino poker providers, I have to say–some states that allow online casino gaming do NOT allow online poker. So, before you sign up, I would double-check your state's laws–you can do so by clicking here.

These are the best online casino poker sites:
