Further down this page we'll explain exactly what makes exemplary casinos so exemplary, and how to recognise whether no deposit bonuses and regular welcome bonuses are as generous and worthwhile as they seem to be. However, if you're no stranger to online casinos and their bonus offerings, we invite you to dive right in by following out direct links to the very best online slots casinos.
Even though we've done all the work for you by finding, vetting and listing the top slots-focused online casinos, we're happy to share with you how we find the casinos we add to our directories. There is no trick to it just seven key factors or criteria that can be used with a 100% success rate by players across the globe to identify the best risk-free slot casinos.
Here are the criteria that we consider when evaluating online slots casinos:
If you ask these eight questions of every online casino you encounter, you will without exception be left with a list of safe, trustworthy and, most importantly, financially worthwhile casinos to play on. These fundamental factors are the cornerstones of DogSlots and what we stand for as they ensure every casino listed here is 'best in class' and thus worthy of its review and recommendation.
This is the first and arguably most important factor to consider when selecting an online casino to play on because if an online casino is unlicensed, nothing about it can be trusted and you should leave it immediately.
Most online casino licenses are expensive and involve a lengthy process to attain. Applying for one or more demonstrates that a casino has gone to great expense and trouble to prove its legitimacy to you, its prospective player. In addition, as part of the licensing process, casinos are thoroughly vetted from top to bottom.
This means if they pick up any anomalies or abnormalities concerning a casino, its owners and/or operators, its game software vendors, its security and encryption measures, its customer care facilities or anything else, the licensing jurisdiction will not grant it a license. If, however, a license is issued, the casino must comply with the licensing jurisdiction's rules and regulations and player protection policies.
Some of the most highly regarded online gambling licensing authorities include the UK, Malta, Gibraltar, Kahnawake (Canada), the Isle of Man and Curacau, so if you visit any casinos licensed by one or more of these rest assured you're in good hands.
When we talk about a casino bonus being worthwhile, we are talking about whether its initial value and potential to payout is worth the time and effort to claim and play it.
All online casinos big or small, well known or unknown offer bonuses whether new player, reload (for existing players), daily, weekly, monthly, holiday or seasonal bonuses to entice players to sign up and try out their latest and greatest games, especially slots.
Needless to say they're very effective in doing just that which is why the one of the first things you'll notice on most casino sites is their generous no deposit cash / free spins bonuses and/or welcome bonus offers. Unfortunately, not all bonuses are created equal as some are way more generous and attractive than others.
The trick is to be able to see further than the offer itself, by examining its respective terms and conditions (T&Cs). Every bonus comes with T&Cs that highlight everything about it including its 'dos and don'ts' and, most importantly, its wagering requirements.
A bonus wagering requirement is the minimum number of times you're required to play through bonus credits and/or free spins winnings before a casino will let you bank or even cash out your winnings. It's the most important T&C because failure to meet the requirement in full will automatically disqualify you from being able to cash out any winnings.
Other T&Cs to look out for include what games are eligible for use with bonus credits or free spins, how each game type or category contributes to the overall wagering requirement, how long a bonus offer is valid before it expires, and what the maximum amount of bonus winnings you can withdraw is (if applicable).
We only endorse casino bonuses with the most lenient wagering requirements, which are the only ones you should take the time to redeem. In the table below you'll find a selection of the very best and latest bonuses you can claim from your location right now.
No deposit bonuses are globally popular because they're 100% free to claim and use. All they require is for you to sign up for a new (and free) casino account to claim them. They're either in the form of free credits you can use to play slots and various other games like Keno, bingo, scratch cards and at some casinos selected table games, or free spins you can only use to play one or more preselected slots. If you fulfil their wagering requirements you're usually allowed to cash out some winnings.
Deposit bonuses are typically much bigger than no deposit bonuses because they always require you to make a deposit to unlock them. Most welcome are percentage-based which means the more you deposit, the bigger your bonus is. You can usually use deposit bonuses to play most casino games (unless otherwise specified in the bonus T&Cs). Some welcome bonuses are only applicable to your very first or initial deposit, while others are valid for your first few deposits, sometimes up to five.
Games are the lifeblood of any virtual casino where the bigger and better its game selection is, the more players it will attract. We only concern ourselves with casinos with the largest and best game suites from the most lauded software developers. These include casinos powered by single or multiple vendors with best-in-class browser-based, mobile-friendly and/or downloadable games.
Typically we list casinos with between 300 and 1000 games as long as they're from top top software providers. Each of these software developers has its own approach to designing and developing of games. What they all have in common, however, is smooth and quality HD and 3D-style graphics and sound effects, generous in-game features, worthwhile payouts and overall an exemplary user experience to hopefully ensure you return regularly.
Here's a list of some of the best globally renowned online casino software developers:
The most popular online casino games categories are slots, blackjack and roulette, with slots by far the most popular game category which is why they eclipse all other games combined.
This is unsurprising when you consider how many different varieties of slots there are (such as classic, video, bonus, progressive etc.) to choose from many top developers. Likewise, blackjack and roulette come in many variants, each more exciting and potentially lucrative than the next. Here's a little more information about these three game categories.
Most modern online casinos are 100% responsive which means they're designed to respond or adapt to any and all platforms including desktop PCs, Apple Macs, laptops, notebooks, smart phones and tablets.
As such we only promote casinos that let you sign up, claim and use bonuses, make deposits, play demo or real money games, make withdrawals and contact customer support on any computer or device of your choosing, all with the same username and password.
A growing number of players around the world only access virtual casinos on their phones or tablets for the ultimate in 24/7 privacy, convenience and flexibility. All they need is a smart device, fast and reliable internet, and the means to fund and defund their casino accounts and they're good to go.
It makes no difference what type of device or brand of device they have, what operating system (OS) their devices uses (e.g. iOS and Android), what internet browser they use (e.g. Chrome, Safari and Edge) or how they connect to the net (e.g. 4G, 3G, LTE or Wi-Fi) as responsive virtual casinos cater to all.
Our recommended sites below are compatible for all platforms.
Slots come in all colours, themes and incarnations which is why they're so universally loved. The 'reel' question is whether a casino has enough slots and more importantly the right slots? The short answer is yes, all the best online casinos featured on DogSlots have more than enough slots 'cherry-picked' from the best casino software developers.
From classic 3-reel, single line 'classic' slots and the latest 5 to 6-reel, multi-line video slots to slots jam-packed with high-paying bonus features to 'millionaire-making' progressive jackpot slots, our comprehensive online casino lists have them all.

The higher a slots return to player (RTP), the better for you the player. That's why we only feature sites with high RTP slots so you have the best chance of winning or cashing out. Also known as 'payout percentage,' RTP is expressed as a percentage and is the average amount of a currency unit (like a dollar, pound or euro etc.) that is paid out as winnings on average over time.
For instance, if a slot has a 97% RTP, it means that over time 97c of every dollar wagered on it is paid out to players as winnings, while the remaining 3c is retained by the casino. This is not to say you or any other player will win at least 97c of every dollar you spend on a 97% RTP slot back because it's an average.
That said, it's always a good idea to play a slot that pays out the most on average than one that pays out the least. We try to endorse casinos with slot RTPs of 96% or higher, but even a 95% RTP can yield you some notable winnings.
Check out these casinos with high RTP slot games:
When you choose to play casino games for real money online, it's of the utmost importance that you can deposit and withdraw funds to your account as quickly and painlessly as possible. That's why we only list casinos that accept the most reputable, safe, trusted, fast and low-fee banking methods.
These can include credits cards, debit cards, e-wallets (like Skrill, Neteller and ecoPayz), prepaid cards, electronic bank transfers and in some cases cryptocurrencies like Bitcoin. The idea is to accept a wide cross-section of payment options so the maximum number of players can be catered for.

It's essential to be able to contact a casino and communicate with a customer support agent around the clock, 365 days a year with any question or regarding any issue - small or big. That's why we endorse only slot casinos with exemplary 24/7 customer care facilities in the form of live chat, telephone and/or email / contact form support.
Live chat is ideal because you can communicate on-site with an agent in real time via text free of charge. Telephone is the next best option, but can be costly if you live in a country or territory where the casino's toll-free numbers are not applicable. Finally there's email, but an email query can take between 24 and 38 hours to be answered.
To free up their support facilities, most casinos also have a comprehensive FAQ section which deals with the most commonly received queries and is thus ideal for first time players.
As soon as you've decided on an online casino based on the key criteria we've highlighted above, it's time to sign up with the casino Luckily the new account registration process at most casinos is very simple and won't take you longer than a minute or two.
Here are the quick and easy steps to follow.
Although here on DogSlots you'll only find 100% tested, vetted and approved safe online slot casinos, the reality is that not all online casinos out there are as legitimate or honest as they seem. In other words, many are 'scam' or fraudulent sites that are unlicensed and virtually impossible to contact. Unfortunately scam casinos often appear to be as welcoming and professional as reputable casinos.
So the challenge is to look beyond a casino's appearance for signs that indicates that a casino is 'bad' and should thus be avoided. That's why we've compiled the checklist below on how to recognise scam casinos. We recommend you stick to the secure and trusted casinos reviewed on this site, but if you encounter a casino not listed here these safety checks will help determine if it's a scam casino or not.
Although signing up and playing at the top slot online casinos we review and feature is pretty straight forward, here is a list of frequently asked questions and answers you may find useful whether you're an online casino newbie or a seasoned pro.
Yes, the ones you find reviewed and featured on DogSlots are. Unfortunately not all online casinos are safe, reliable or trustworthy and those are the sites you must avoid. Rest assured we personally vet and play on every casino we endorse, so you can play at any of our listed casinos with complete peace of mind.
Yes, the ones we promote and test are. Like any successful businesses, legitimate casinos aim to attract new players and retain them for as long as they can. They achieve this by being honest, open and fair in their dealings with them, and ensuring their software, systems and processes are secure and safe 24/7 using state-of-the-art encryption.
Yes. Online casinos compete with land-based casinos. This means they have the same games with the same odds and payouts. In fact, because online casinos don't have the space constraints land casinos do, most have even more games to choose from. And unlike land casinos, most online casinos offer free to play 'demo' games for you to practice on.
All premier online casinos are supplied games by the best software developers who to stay current, competitive and attractive to players ensure their games have the highest payouts. And here at DogSlots we only seek out, vet and promote the best online casinos so in the answer to the question, all of our casinos have high payouts.
Some online progressive slots have jackpots that reach millions before they pay out. However, in terms of regular online casino games, titles aimed at high rollers can be lucrative because of they allow larger than average bet sizes and thus have bigger payouts. Look out for casinos with a Prive section that have higher limit games.
No, you can usually also play demo games for free. Some casinos let you play demo games without an account while others require an account. Regardless, demo games are identical to their real money counterparts and are a great way to practice games and learn their features before switching to their real money versions.
This is hard to answer because everyone has different tastes. You may prefer the latest and most lucrative online slots, while the next player may prefer to place his or her bets on the Roulette table. Others may gravitate towards live dealer games because they enjoy the interaction with real dealers in real time. The choice is yours.
Online slots have pay tables that list their maximum possible payouts. However, the category of slot games with the biggest payouts are progressive jackpots. Although they look and play like regular slots, their maximum payouts are unlisted because they're dependent on their ever-growing progressives that in some cases grow to millions before they pay out.
In 2018 one lucky - and anonymous - online slots fan sent waves around the online gambling world when he won a record €18,910,668 progressive jackpot of Mega Moolah slots from Microgaming. As of November 2019 that record remains intact but it's only a matter of time before an even bigger jackpot makes another player an instant millionaire many times over.
With online games your winnings are automatically credited to your balance. At the end of a session you can logoff with the knowledge that your funds will be protected and untouched until your next session. If at any time you want to cash out just visit the casino's cashier / banking page and select a suitable withdrawal method.
This all depends on where you live and your respective state, territory or country's laws and regulations on gambling winnings and taxation. Remember that the responsibility is yours to find out your country's stance regarding online gambling i.e. whether you're legally permitted to gamble online or not, and whether your winnings are subject to taxation or not.
It all depends on whether a particular casino accepts players from your territory or country - so it's nothing personal. The good news is that because out site uses state-of-the-art geo-targeting software, you'll only ever be presented with lists populated with top-rated slot casinos that welcome players from your particular location.
It's our sole intention at DogSlots to equip you with all the information and tools you need to make smart, informed and advantageous decisions about the best, safest and most entertaining slot-focused online casinos. It's the same information and tools our reviewers use to find top casinos and add them to our directories. This allows you to read up on any casino before linking to it directly. It's as simple and convenient as that.
