Best slots sites reviewed and rated by experts
To help you find the best slot machine website for you, all online casinos, including each slot machine site you can see on this page, have been reviewed and rated by the Casino Guru review team.
All our reviews follow an objective review methodology, which allows them to remain impartial and truthfully describe the reputation and quality of each reviewed online casino or slots site. This way, we can help players understand the pros and cons of each gambling site and make the right choice.
Casino Guru review methodology
Our review team looks at these qualities and characteristics when reviewing real money slots sites:
- Size and number of players – Top slots sites with large numbers of players tend to be safer for players, as their large revenues allow them to pay out even the biggest wins. Also, the fact that many players gamble at these websites is also a sign that they must be doing something well.
- Complaints from players – Complaints submitted by players about individual slot websites – and how the sites handle them – also play a crucial part in our review methodology. If many casinos complain about the site's unfair practices, for example, we decrease its reputation rating. All complaints are listed in each gambling site's review.
- Unfair rules and practices – We go over each slots website's Terms and Conditions and consider their validity and fairness. If we find unfair clauses in them, we decrease the site's rating and warn about the unfair rules in our review.
- Blacklists – If the casino appears on relevant blacklists, including the Casino Guru blacklist, we decrease its rating and warn about the blacklist in the review.
- Related gambling sites – For each slots site on this list, we also consider any related gambling sites. For example, when many players complain about another site managed by the same company, this is reflected in reviews and ratings of both sites.
- Positive qualities – If the site does something well, like approaching player complaints generously and going out of their way to meet players' demands, we may decide to increase its rating.

How online slots work
Online slots started as digital versions of slot machines you may have seen at land-based casinos or gaming halls. Since then, game developers have been coming up with creative themes, features, gameplay elements, and other characteristics that are making slots the most popular casino games on the internet today.
Traditional online slots are made up of reels with a range of symbols on them. You spin the reels and hope the symbols create a winning combination on an active win line. They may also come with special features, which are triggered either on random or by landing a certain number of special symbols. These most commonly include free spins or other types of bonus features.
Many modern online slots come with innovative gameplay elements, like cluster pays, in which winning combinations are created by clusters of symbols touching each other, as well as many other inventive features. With thousands of casino games created by hundreds of companies available, you can find pretty much anything.
Mathematics of online slots – house edge, RTP, and variance
Slot machines are configured to give the casino an advantage, also known as house edge. The average house edge of online slot machines is around 4%, which means that players lose 4% of the wagered amount on average in the long term. That said, the house edge can me lower or higher, depending on the specific slot machine and gambling website.
The RTP (return to player) – also known as payout ratio – is calculated as 100% minus the house edge and expresses the percentage of wagered funds players can expect to get back as individual wins, statistically. Games with a 4% house edge have an RTP of 96%.
Meanwhile, volatility (also known as variance) expresses how big and frequent individual wins are when playing a given slot machine. High volatility slots have a potential for large wins, but winning spins tend to be less frequent. On low volatility slots, you can win more frequently, but individual spins are usually smaller.
Note: You can learn more about slot machines in our separate article on how slots work. It explains the mathematics of slot machines in more detail, as well as how they are programmed and common slots myths and misconceptions.
Strategies for real money slots play
Because of the casino's mathematical advantage over players, you cannot expect to be profitable playing slots in the long term. No strategy you follow can change that, so do not believe people or websites telling you that you can reliably win money on slots.
That said, there are things you can do to improve your chances of winning or minimize your expected losses.

However, always keep in mind that you are playing at a disadvantage and should expect to lose money in the long term.
How to stay safe when playing real money slots
The best "strategies" to follow when playing slots for real money are safe gambling principles. Gambling can be dangerous if it gets out of hand, so it is crucial you approach it carefully and set preventive measures. Here are some of the most important things to keep in mind when playing real money slots:
- Understand that playing slots is not a way of making money. You should see it as a form of entertainment that you pay for by playing at a disadvantage.
- Only gamble with money you can afford to lose. Do not chase your losses nor play with borrowed money. Set a budget in advance and stick to it.
- Do not play when in a bad state of mind nor under the influence or alcohol or drugs.
- Watch out for symptoms of gambling addiction and take action if you feel like you might be at risk.

Bonuses offered by online slots sites
Gambling websites often offer bonuses and other promotions to new and existing players. Bonuses for new players are generally the most generous, as they are used to attract new players and give them an incentive to sign up and start playing.
Some bonuses are completely free, also known as no deposit bonuses. These are given to new players without requiring them to make a real money deposit. The two main types of free bonuses are:
- Free spins bonuses – These consist of a certain number of free spins, which can be used on selected slot machines. This makes them popular amongst slot machine players. However, their shortcoming is that they limit which games you can play with them.
- Free cash bonuses – These consist of free bonus funds added to your account. Apart from games specifically restricted in the terms and conditions of the bonus, you are free to play any games you want.
Deposit bonuses, on the other hand, are given to players as a reward for making a deposit. Understandably, these tend to be larger, but you need to deposit your own money to get them.
Note: Online casino bonuses come with a set of restrictions specified in bonus terms and conditions, which means you must follow some rules when playing with a bonus. Read our article about how casino bonuses work to learn more.
Try online slots for free before playing for real money
If you are new to online slots, we recommend trying them for free first. Our database of free casino games contains thousands of free slots, which you can try without spending any money.
These games work exactly the same as their real-money counterparts, but you play them with so-called play money instead of actual cash. This way, you can get to know the titles and learn what to expect when playing them. If you like them and decide to try them for real money, you can do so by creating an account at one of the best slots sites listed on this page.

How do online slots work?
Most online slots work similarly to land-based slot machines. You select your bet size, press the spin button, and hope that the symbols on reels create a winning combination. That said, casino game providers keep coming up with creative types of slot machines and innovative features, which make gameplay more varied and interesting but sometimes also more complex and confusing.
Which slots sites have the best payouts?
All casino games are configured to give the casino an advantage. This is known as the house edge. The higher the house edge, the more money you lose in the long run. Therefore, slots with the lowest house edge theoretically have the highest long-term payouts. Most games have the same house edge at each gambling site, so your game selection is generally more important than the slot machine slot you play at.
To make sure, choose a site which lists the payout ratio or house edge of each available slot, so that you know what payouts you are getting.
Can I win real money playing online slots?
Of course. That is what real money slot websites allow players to do. To be able to win, you will need to create an account using your own personal information, make a deposit (or use a no deposit bonus), and be lucky enough to win.
Are slots sites available on mobile devices?
Yes, most slot machines can be played on mobile devices, including iPhones, Android phones, tablets, etc. Many players visit slot websites using their phones, so it is in the casinos' best interest to make their games optimized for mobile devices.
