The Best Online Casinos for 2021

It’s impossible to pick one casino as the best choice for everyone. As each player has different needs and preferences, the best online casino for one player might be a terrible choice for someone else.

That said, we’ve reviewed thousands of casinos to find out how they treat their players, and then considered local factors for each country with the help of local testers. Casinos are then ordered from best to worst based on our findings, so you should be able to find your best pick near the top of this list.

All casino games have a certain house edge, which means the casino always has an advantage. You can, however, get lucky and hit a win despite the unfavorable odds.

That said, if you keep playing, you are much more likely to end up with a loss than with a profit. If you manage to win, we advise you to withdraw your money, because you will certainly lose if you keep wagering your money over and over again.

We have seen many players who managed to win tens of thousands of euros and then gradually lost all of it during the next few days or weeks (or even faster) because they kept playing and didn’t withdraw their winnings. That’s why we recommend players to be smarter than that and take their winnings if they get lucky and win. And it always helps to play in reputable online casinos.

There are reputable online casinos, but there are also casinos with bad intentions. If you choose an honest and reputable casino to play at, you can be pretty much sure that you will be treated well, and your winnings will be paid out to you unless you really do something against the rules.

However, if you play at a casino with a bad reputation, it’s much more likely that you will run into issues, e.g. casino looking for excuses not to pay out your winnings, etc. That’s why we stress the importance of casino selection as much as we do.

All casino games give the casino a certain statistical advantage (house edge), so you are more likely to lose money than to win. However, if you think that casinos manipulate games to give them an even bigger advantage than the advertised house edge, that’s not the case. Casino games are operated by the company which created them, not by the casino itself, so the casino can’t influence the outcome of game rounds at all.

The only exception to this are fake games, which are created to resemble other original games, but with a different set of payouts and probabilities. Fake games are generally used by dishonest online casinos to trick players and increase their profits, but you will not find them at any casino which has a good rating from us. If we discover fake games at a casino during the review process, we decrease the casino’s rating and warn our visitors.

The best way to find a trustworthy online casino is to pick a big online casino with a large number of players and big revenues, which we’ve given a high reputation rating. Large casinos are generally safer for players, because they have big revenues which allow them to easily pay out players even if they win really big. And if a casino was rated well by our review team, it means it generally treats its players fairly and doesn’t try to trick them.

Either way, we advise you to read our full review before starting to play at any casino to learn everything you need to know to decide whether it’s a good choice for you or not.

Most online casinos can be accessed using pretty much any device with an internet connection and a browser. There are still some casinos which are not optimized for mobile devices, but their number is, fortunately, getting smaller and smaller. Major computer operating systems (Windows, Mac, Linux) and popular types of mobile devices (iPhones, iPads, Android phones, Android tablets) are generally supported.

If you plan to gamble using a mobile device and want to make sure the casino you choose supports it, use the ‘Mobile-friendly casinos’ filter above or go to our dedicated list of mobile online casinos.

Available currencies you can play in usually depend on which countries each casino targets. Major currencies like US Dollar, Euro and Pound Sterling are supported in most casinos, but many online gambling sites also support less common ones. To make sure you can gamble in your preferred currency, use the ‘Currency’ filter above.

Some online casinos also allow players to deposit in cryptocurrencies like Bitcoin, Ethereum, Litecoin and others. You can browse these using the ‘Bitcoin/crypto casinos’ filter above, or by going to our separate page with the list of best Bitcoin and crypto casinos.

This is quite a common myth in the gambling industry. The payout ratio (RTP) is not influenced by the casino you play at, but by the games you play. Generally speaking, if you play the same game at two different casinos, your chances of winning are the same, at least if we ignore factors like bonuses, promotional offers, etc.

It’s also true that some game providers create their games in multiple configurations from which the casinos can choose the one with their preferred RTP, your payouts generally depend on your game selection and style of play, not on your casino of choice.
