The Best Online Casinos in the US

For most states in the US, there hasn’t been legislation passed that allows real-money online casinos to operate. Many states believe that allowing real money online casinos to operate within their borders, will cannibalize the land-based casino market. However, some states have moved ahead of the rest and legalized the online gambling industry and include online casino gaming in their offerings. If you find yourself in a state that hasn’t legalized online casino gaming yet, then you will have to rely on playing casino games at social casinos.

While some online casinos offer sweepstakes games where you can win real money prizes, this is not the case with all social casinos. Here is a comprehensive list of the social casinos you will have access to, but be aware that you will not have the option to win any real money.

Types of Online Slots

When you visit land-based casinos in the US, some of these casinos are home to more than 3,000 slot machines. That means that there are a lot of different types of slots that can be played. When it comes to online slots, the diversity of these games increases even more, given that there is more freedom to develop games with additional exciting features which are more accessible.

In many cases, especially with the most popular online slots, there are some common types of slots that are available. Some developers always keep the original recipe to ensure that there is some familiarity when players decide to choose one of their slot games. Here is a breakdown of some of the most popular slot types that you will find at online slot casinos that are sure to be extremely entertaining.

Three Reel Slot Games
Multi-Reel or Multi-Payline
Video Slots
Progressive Jackpot Slots

Three Reel Slot Games

This is considered a classic and is simple to play and understand. These three-reel slots date back to the very first slot machines at land-based casinos. It has simple rules and all it requires is that you match three symbols on one payline to win. Some of the symbols you will see will be fruit, card denominations and even horseshoes as a sign of luck.

Multi-Reel or Multi-Payline

There are many more ways to win when it comes to these types of slots. It also shows just how far developers have gone to make the game of simple slots more entertaining and that much more exciting for its players. There is a chance for you to win across 50 paylines in some cases and with more complex games there is a possibility of winning on more than 100 paylines all at once. These games usually have bonus features or levels for you to play as well.


Video Slots

Electronic versions of the classic slots which adds a lot more excitement to the game without complicating the rules. These games are also usually themed to improve the overall gaming experience at a land-based casino. When you find these at online casinos, there are so many familiar themes and even ones you never would have dreamed of. These slots also have great bonus levels for you to try and win even more than you set out to at the start.

Progressive Jackpot Slots

These games are connected on a network of online slots where each bet that is placed forms part of an ever-growing jackpot. Some land-based casinos have several of these slot games in a casino that all contributes to an overall jackpot. When it comes to online casinos, the jackpots can grow into the millions quickly given that the same game or range of games on the same network can be played by millions of players every day.

Best Payout Online Slots

When playing any slot game, it is important that you figure out what the payout percentage is before you get started. It’s not something you need to know, but it is something that is good to know and gives you an understanding of how likely you are to win. The payout percentage or return to player percentage can tell you a lot about your opportunities to win. For physical slot machines, these RTP rates are usually lower than the online slots you play at an online casino.

So, even if it is the same game that you are playing, the online slot is likely to offer you a better chance of winning than the land-based version. Land-based casinos have more overhead costs to cover and slot machines are the most popular game in any casino. With fewer overhead costs, online casinos can offer players better RTP percentages. An example of how an RTP works goes something like this:

If the RTP is 97%, then for every $100 spent at the slot game, on average, the game will payout $97 for every win. Remember that slot games are games of chance and completely random and this doesn’t mean that every time you spend $100 you will be winning at least $97. To check the RTP of a slot game in a land-based casino, you can check the label on the game or you can google what the RTP is as this information is freely shared by the game developers. Here is a list of online slots that we have found that have the best RTP rates out there.
