Even before you read this guide, you will have known that there are a huge number of online casinos in the USA. This means if you want to open a new account, you have the task of checking out each operator, one at a time, and finding out if they are licensed to operate in your state before you can look at any of the other things you need to find out.

Clearly very few people want to do this, so you are more likely to pick the one with the bonus that looks the most appealing and get started. Unless you are very lucky, you might quickly find yourself out of your depth. Not because the operator isn’t trustworthy, but because you’ll quickly find that there is more to playing slots online for real money than you thought.

This is where the guide can help you. Rather than pick the first one that catches your eye, you can use the information in this guide to help you find the perfect place for you to start. This information is put together by our team of expert reviewers who will tell you what you need to know about the places you can play slots, as well as casting their expert eye over the bonuses involved, so you know exactly what you are signing up for.

Even if this is not your first time, and you think you know how to win at slots machines, there is plenty that this guide can do to help you. You no doubt already know how long it can take to look at all of the options, or have found out from bitter experience what happens if you make a hasty, uninformed decision. If this is you, then you can use the resources in this guide to do all of the heavy lifting for you, and leave you with just a few places with legal slots online to check out.

After reading what are some pretty big claims in the last section, it’s probably best we take a moment to show you how we can do that. Here at TheGruelingTruth.com, we have a specialist team of expert reviewers who carry out in-depth research and review each operator that offers legal slots online

They do this using a set checklist of things to discover and report back on. So, when they look ‘under the hood’ to tell you what an operator is really like, the information you get back covers all of the same points; so, you can compare operators easily. Of course, this list of criteria is quite extensive, but to show you that we ‘know our stuff’ and look for all the same things you would, here are five of the main things we look for.

This is at the core of whether or not you are going to have a good experience playing legal slots online, so we check that the slots you are going to play are definitely ‘legal.’ We check the online casino we are reviewing is licensed to operate in your state and report back on what we find. We’ll also raise any red flags if we find out that the reputation of any parent company is not that great.

2. User Reviews – we check the good and bad reviews already online

Checking existing users’ reviews is another method we use to rate operators. User’s reviews are important because it provides proof that the operator can be trusted, and highlights any issues that we may have to pay close attention to when we carry out our own in-depth, objective examination. While we understand that many user reviews are likely to occur because of one isolated incident, several of these about the same thing might give us cause for concern.

3.  Customer service – great options and quick responses

A friendly and helpful customer service team is a great way to retain customers. We rate operators based on how quickly their customer services respond to complaints and resolve them. We’ll do this by looking at responses from live chat and email, as well as what they tell us via phone support if it is available. We’ll also see what the FAQs section has to offer and if this means that most of the time you won’t need to contact customer support in the first place.

4. Customer funds – how they protect your money

This isn’t about taking payments (that’s next), but how the operator looks after your money while it is with them. Protection of funds is necessary to make customers feel safe enough to entrust their money to the operators. Our rating takes into consideration how each operator protects customer funds. This will involve any security measure they have in place against cybercriminals, and also whether they keep customer money separate from their operating funds. This means that if the operator gets into financial trouble, your balance won’t be used to bail them out.

5. Payment method – how you go about making and receiving payments

The payment options offered by an online casino is another factor we consider while rating and reviewing operators. It is important to check how easy it is for customers to make and receive payments and the amount of time it takes for transactions to be processed. We’ll let you know all of that and any fees the operator might add for taking payments using specific payment options like a credit card.

As you can see, we examine each operator that offers legal slots online objectively and rate each one according to what we find.  With that information, you might feel that you don’t necessarily need to look at those reviews, but instead would be interested in our editor’s recommendation.

This is compiled using feedback from our reviews, tied in with other factors that are particular to playing slots. So rather than ‘just’ the best operator, we are looking for one that offers a large range of slots from a number of premium software suppliers. We are also looking for one with a decent variety of slots, including jackpot slots for those who like the big wins. Of course, we also look for one where the slots load and play without problems on desktop as well as the mobile app.

The one operator that tops this list is Caesar’s, which edges out BetMGM by the barest of margins. Caesar’s have all of the features we look for and a remarkable bonus that is a good fit for new and more experienced users to take maximum advantage of.

Here at TheGruelingTruth.com, we know that not everyone is looking for the same thing. This means that while Caesar’s might be exactly what most people are looking for, it might not be right for you. That’s perfectly fine, as those same reviews can help you root out all of the particular features you are looking for without having to look at every single site yourself.

This will probably come as a relief, as new legal slots online users would not know where to start, and if you have played before, you’ll know how much time this can take.

How to use our online reviews to find exactly what you are looking for

As we mentioned earlier, the reviews all cover the same areas, making them easy to compare features. This means if you are looking for slots from a particular supplier, you’ll be able to see which online casino offers these. The same goes if you want to use a particular payment method, or if you play at night, and want one that has 24/7 customer service.

As we go into every detail in our reviews, we are the ‘go to’ source for expert information that can save you time and effort. This not only means you don’t have to do the searching yourself, but you are also having an expert eye cast over all of the different choices that might spot something you would have missed if you had looked by yourself.

Getting off to a good start with your chosen operator is another important step when playing legal slot machines online. Regardless of whether you’ve taken our recommendation, or found one that’s a perfect fit for you, you’ll want some tips so you can make the most of the experience, So, while you make have played slots before and know all of the slot rules, you’ll need to bear these 5 things in mind:

Decide if prefer frequent smaller wins, or occasional larger ones

This will depend entirely on your betting style, so if you prefer regular wins to keep you motivated and your bank ticking over, pick those machines. On the other hand, if you are patient and get a buzz from bigger wins, look more toward jackpot machines. (Although you might want to steer clear of progressive jackpot machines)

Make the most of your bonus

Your bonus balance can be used in one of two ways. You can play as you normally would and try and build your bank as much as possible from your free spins or deposit match, or you can take the opportunity to use this balance to try out new machines and see if there is anything there you prefer playing.

Look out for bonus symbols

This is not the operator bonus, but the bonus features of the slots you are playing. Matching these symbols can set off mini-games that you might like to play, and reward you with free spins. Obviously, this adds an extra dimension to the slots you are playing, so if you like this aspect, look out for the games with features like this.

Set yourself limits

Playing slots is fun, which is why you do it. There are many different slots to play with plenty of different features that can keep you engaged for a long time. To stop this affecting other things you might want to do, you could set limits on how long you allow yourself to play for each day (like just during your lunch break at work) or the amount of money you get through during a session.

Don’t look for patterns

Slots work using RNGs (random number generators) so looking for patterns might be a fool’s errand. Thinking that seeing a certain pattern of symbols means that your next spin will deliver a win, or playing beyond your normal limits because ‘it’s due to pay out’ is likely to be based around emotion rather than reality, and typically does not end well.

Looking back at what you’ve discovered in this guide, you’ll be aware that there is both a hard and easy way to find the operators with the best legal slot machines online. The hard way is going from site to site yourself, checking each one for the features you want, and a bonus that suits your needs.

On the other hand, you could use the resources and reviews here at TheGruelingTruth.com to sidestep all of that unnecessary work and use the expert reviews to narrow down a massive number of potential casino operators to just two or three. You can then inspect those yourself and make your final decision, or just go for our editor’s recommendation.
