What to Look For in an Online Casino

There are so many online casinos out there promising top-notch experiences and huge wins, but some of these casinos are not quite what they seem. We’ve done all the leg work for you and sorted out the good from the bad. When you play at one of our recommended casinos, you can be sure that you’re playing at a casino that has been thoroughly analyzed and critiqued. But, if you’d like to do a little research on your own before signing up to play, here are some things that are crucial to a positive gaming experience:

Game Selection

The best real money online slot sites and casinos must have an extensive collection of slots, table games, specialty games, and more. At top-rated slot sites, you will be able to find multiple slots that suit your needs and playing style. Whether you’re looking for classic 3-reel slots or 5-reel video slots with a Christmas theme, there will be a game that’s perfect for you. It’s also imperative that you are able to play free online slots at these sites. Playing for free allows you to practice the game and understand the bonus features before risking your own bankroll. 

Fast Payouts

Of course, the most thrilling aspect of online casinos and slot games is the ability to win real money. When you choose a casino, you should absolutely be checking their payout speeds. Reputable online casinos will always clearly state their payout process, payment methods, and speeds, and then abide by those rules. The time range to receive your winnings is typically 3-10 business days. Casinos that “play dirty” and go through hoops to withhold players’ rightful winnings will quickly find themselves on blacklists and gain a reputation as a rogue casino. 


Of course, it’s not worth playing at an online casino that does not have the proper licensing and is not regulated by the appropriate authorities. You will be able to find this information in the footer of the home page. The casinos that we recommend to players will also all employ SSL encryption technology to ensure that every transaction is kept safe and secure from any fraudulent activity.

Customer Service

Having a top-notch player support system is a must for any leading real money online slot site. Our recommended casinos have multiple contact methods including live chat, email, and telephone. If you have questions or concerns about games, banking transactions, bonuses, and everything in between, you’ll find your answers with the highly trained casino professionals. 

Real Money Slots vs Free Slots

The important thing about free online slots is that it allows you to try out new games entirely for free. You can learn how the bonus features work, and if the theme is as satisfying as you thought, all without risking any cash of your own bankroll. 

Types of Slot Machines

When playing online slots, you’ll discover many different types of online slots. Each variety has its own characteristics and pros and cons. The most common three types of online slot machines are: 

Classic 3-Reels

If you want to go the traditional route, you can find classic 3-reel slot machines complete with cherries and lucky 7s. These slots are perfect for those nostalgic for old-fashioned slot games. Classic 3-reel slot games might not have all the frills of the new, special-themed slots, but they still pay out in heaps just the same. You can find these classic favorites at any of our recommended online casinos. 

Video Slots

Video slots are a testament to the evolution of online gambling. You can find a suitable slot for any and all of your interests! From popular movie and tv titles to Santa Claus and zombies, there’s something for everyone! These slots offer unique bonus features such as multiplying wilds, special symbols, and pick bonus features, that really amp up your gaming experience. You can try out any video slot for free at reputable online casinos so you can get to know the bonus features before wagering your own money. 

Progressive Slots

Progressive slots are perhaps the most sought-after slot games around. They offer the highest rewards and often come with really exciting bonus features and themes. Progressive slots typically have a high volatility due to the massive payouts that can be won. A slot with a high volatility means that particular slot will pay out less frequently, but in much larger amounts than low-volatility slots.

Tips for Winning at Slots

While there are no exact tips to winning at slots, there are a few things you can do to maximize your winning potential and have a more enjoyable slot experience. 

Set a Budget

Setting a budget (and sticking to it!) should be your number one goal before you even start the game. If you spend your time and money chasing losses, you can easily wind up so far in the hole that it feels impossible to climb out. Obviously, this is not what you want. If you find yourself on a losing streak and are close to hitting your limit, consider stepping back from the game for some time and trying again later. 

Know Your Game

To get the most out of your slot session, it’s important to fully understand the game you’re playing. A great way to do this is to take advantage of the freeplay option that our recommended casinos have. Playing in freeplay mode allows you to test out the game and get to know the bonus features completely before wagering your own money. If you know how the game works, you’ll increase your chances of having a positive time playing. 

Understand RTP & Volatility 

Volatility and RTP are characteristics of a slot machine that let you know what type of game you are getting into. RTP stands for Return to Player, and this is essentially the amount of money that will be returned to players over a certain period of time. For example, players can expect to lose $3 per $100 bet on a 97% RTP game. Keep in mind that this is an average, and you will not necessarily hit that mark every session. 
A slot’s volatility determines how often and how big a slot will payout. A slot game with low volatility will pay out often, but in smaller amounts, whereas a slot with high volatility will not pay out as often, but when it does it is in huge amounts. A medium volatility slot, of course, falls somewhere in the middle. Low volatility slots are great for casual players looking to unwind after work without wagering a ton of money. High volatility slots are geared toward high-rollers looking to hit a huge payday. 
You can find a slot of any kind at our recommended casinos. The RTP and volatility of a slot should be clearly stated at the casino so you can make an informed decision before sitting down to play. 


Online Slots FAQs

Return to player represents the amount that a casino will pay back to players over a certain amount of time. For example, if you place a hundred $1 bets on a slot that has an RTP of 90%, you can expect to get around $90 back in wins. Keep in mind that this is a general estimate, and it is not guaranteed that for every $100 spent you will receive $90.

When you play at a reputable online casino like the ones that we recommended, you are guaranteed fair gameplay. The top US online casinos run their games on Random Number Generators, which are complex algorithms that ensure each turn is completely random. The games cannot be rigged, and players cannot cheat them. Potentially, players have a chance at hitting the jackpot with any spin of the reels!

Absolutely! That is perhaps the most exciting thing about playing online slots for real money. As long as you are playing at a reputable online casino, you have the opportunity to walk away with more in your bankroll than you started with.

Slots at the casinos that we recommended are totally random, so there isn’t a way to know exactly which slot is a winner, however, there are a few things you can do to increase your chances of winning. It’s important to look at the volatility of a slot. A low volatility slot will pay out often but in small amounts. These slots are perfect for casual players who don’t want to relax and play their favorite games without wagering too much of their own money. High volatility slots will pay out less frequently but in extremely high amounts. These are perfect for patient, high-stakes players who play with the purpose to cash out a lot of money and have the bankroll to support this type of playing style.
