30 Best Online Casinos, Slots, and Apps To Win Money in 2023

Love playing games to make money? No problem, just hop on a flight and visit the Las Vegas strip or drive to your nearest local casino to play your favorite slot machines and table games.

Until recent years, if that wasn't an option for you, you'd have been out of luck. However, now, there are plenty of alternatives available, like online casinos, slots, and other game apps you can play on your mobile devices to win money. Like most industries, casinos have found a way to deliver their product online. The number of online casinos has grown in the past decade, and today online casino sites are easily found online.

As a result, online casinos are increasing in popularity and are worth a look.

Short History of Online Casinos

Online casinos started in 1994. Reportedly, the government of Antigua and Barbados passed the Free Trade and Processing Act, which allowed casinos from other countries to apply for licenses to open online casinos. As a result, Microgaming and Cryptologic built the first online casino gambling software.

In 1995, Microgaming launched the first online casino, The Gaming Club. In 1996, the first real money was gambled on InterCasino, and the company had 18 games in 1995. Also, in 1995, the Kahnawake Gaming Commission was established in Canada to issue online casino licenses.

Today, online casinos are a multi-billion industry, and the market is estimated to grow to more than $80 billion by 2025.

How do Online Casinos Work

There is little difference conceptually between regular and online casinos, and the games are the same. Depending on the state, you can play online slots, roulette, craps, blackjack, etc. Money is bet by gamblers and won or lost. Generally speaking, you must be at least 21 years of age to legally gamble real money in the US today, whether playing in land-based casinos or online gambling sites.

However, some states allow people 18 or older to gamble in certain situations. For example, in some states, poker can be played at 18. In addition, sports betting sometimes has a lower age requirement depending on the state, and age requirements vary abroad.

Pros of Online Casinos

However, online casinos offer convenience since you do not need to be physically present at the casino to gamble. You can also play for any amount of money you choose, which is helpful if you have a small budget and want to play longer. One significant advantage is you can learn to play for free on many online casinos. This allows you to practice and become familiar with individual games; then, when ready, you can switch to playing real money games.

Live Dealers

A recent innovation in online casinos is live dealer games – a combination of online and in-person gambling. The live games are hosted at a land-based casino, and a live dealer is on camera. So, for instance, you can play blackjack over the internet with a live dealer.

Bonus Offers

Online casinos use bonuses to entice gamblers to play as long as possible. Different types of bonuses include welcome bonuses, free spins or credits, deposit bonuses, and loyalty bonuses.

Welcome Bonuses

A welcome bonus is also known as a sign-up bonus. Extra money, or bonus funds, is deposited in your account as an incentive to sign-up with an online casino. For example, Red Dog Casino offers up to $12,250 for new players, while Ignition Casino offers $3,000. Welcome bonuses can range wildly from only a few hundred dollars to very generous bonuses.

Some online casinos have conditions for the welcome bonus. For example, both Bovada and Café Casino require an initial deposit in Bitcoin to earn the online bonus. At the same time, Red Dog gives a 20% boost for Neosurf or Bitcoin deposits.

In many cases, you must play for a particular amount of time or number of games, bet a certain amount, or make a minimum deposit to earn the bonus. Be sure to read the fine print, terms, and conditions when you sign up and take the welcome bonus.

Other Bonuses

In addition, online casinos offer free spins in slots and credits for tabletop games. Other possible bonuses include:

  • Deposit bonus – awarded when you deposit more money into your account.
  • Loyalty bonus – awarded to members of the casino's loyalty program who gamble a certain amount of money – this type of bonus is often tiered.

Which States Have Online Casinos

In the US, online casinos are not available in all states. States that have legalized online casinos will have regulated casinos. New Jersey was the first state to approve legal online gambling and, thus, online casinos. You can choose to gamble at land-based casinos with online operations or strictly online casinos.

New Jersey has more than 20 operators of online casinos, and the following states have approved online casinos since 2020: Pennsylvania, West Virginia, Michigan, Delaware, and Connecticut. States with bills introduced include New York, New Hampshire, Massachusetts, Illinois, and Louisiana. More states have legal sports betting than online casinos.

Unfortunately, you must be physically located in a state with legalized online gambling to play real money casino games. It does not matter if you live in a state and are traveling or temporarily residing elsewhere. However, you can sign up from anywhere and plan to travel to a state with legal online gambling.

Many countries besides the US have online casinos, each with its own rules and regulations. Online gambling is prevalent in Europe and Asia. Some of the oldest players in the online casino industry are licensed and operated in the UK and Canada.

Types of Online Casinos

Online casinos are not all the same. Three online casino formats are download software, web browser-based, and mobile apps.

Download Software

When online gambling first started, the internet was slower than today. Downloading and installing an online casino program is one way to get around the slow speeds. This method was the primary format once disk installations were obsolete for those who played video games before broadband was widely available.

Once installed, the program would connect to the casino servers. The advantage is that graphics were cached locally on your computer and did not have to be downloaded. Although dated, there are still online casinos that still offer this format.

Web Browser Based

Accessing an online casino through a web browser is probably the most common method for gamblers to play. In this case, the graphics and games are served through the internet. Speed is dependent on your internet connection and the casino's server speed.

The advantage here is that you don't need to download unknown software onto your computer. A second advantage is that you can log in from any device, including desktop, laptop, tablet, and smartphone.

Mobile Apps

The third method of accessing online casinos is through an app on your smartphone or tablet. The speeds can be faster than accessing the casino by a web browser. The concept is similar to downloadable software; you can only use the app on one device. Most of us are familiar with downloading an app from the Apple App Store for iPhones or Google Play Store for Android devices.

Criteria for the Best Online Casinos

The world of online casinos is complex and rapidly growing. Therefore, what qualifies as the best online casino may differ for each person. However, you can consider the following criteria for determining the best online casino.


The first criterion is a bonus. If you are all about getting free money, look at the welcome bonus. Prizes often change, so checking a site after reading a review pays. As mentioned above, there are requirements to earn a welcome bonus.

You cannot just sign up at an online casino to get the welcome bonus and leave without ever playing a game. Casinos would quickly go bankrupt if that were the case. So instead, look at the dollar value, what you get, and how you need to earn it. The headline dollar value may be impressive, but the average bonus may be lower.


Convenience is a requirement, especially for gamblers that play often. You can use a web browser-based online casino or downloadable software if you play on your desktop or laptop.

Questions you need to ask yourself are related to speed, navigation, and ease of installation. But a mobile app-based online casino may be a better choice if you want to play anywhere.

You can find mobile app evaluations on the Apple App Store or Google Play Store. This is important because the games must be optimized for a smaller screen.

Number and Quality of Games

Online casinos differ in the number of games they offer. For instance, Red Dog Casino offers more than 200 games. On the other hand, if you like slots, Ignition Casino has more than 200 slot machines, and Slots LV has more than 3,000 slot games and 70 3D slots. In addition, super Slots has more than 30 video poker games.

However, the number of games alone is insufficient for an excellent online casino. You need to ask yourself about the quality of the games. Are the graphics superb and seamless? Is the sound quality good? How about the animations?

Customer Service

Not all online casinos have the same customer service level; however, this criterion is difficult to evaluate unless you play and interact with customer service. Check some websites that consider customer service for an idea about it before you sign up.


Online casinos deal with real money, so security is essential. An important question that needs to be answered first is whether the casino is licensed by the state's or country's regulatory body? Is SSL encryption being used by the casino? What details is the casino asking for? What is the privacy policy of the online casino?

How is your money secured, and how easy is it to withdraw your winnings? What are the deposit methods: credit card, cryptocurrency, wire transfer, check, or other methods? Note that credit card deposits may have fees. In some cases, unlicensed casinos may have higher deposit fees.

Return to Player

Lastly, most gamblers are concerned about Return to Player (RTP) percentage. This metric is the percentage of wagers a specific game will return to the player over extended periods. For example, if the RTP is 90% in a slot game, you will likely lose 10% of your money over time.
