Our 7-Step Review Methodology

When our team members review online casinos, all of them always follow our scientific process.

  1. 1. Register an account
  2. 2. Deposit funds
  3. 3. Try some games
  4. 4. Contact support
  5. 5. Withdraw funds
  6. 6. Research complaints and reputation online
  7. 7. Report back to us through a questionnaire of 50 questions.

From there, we rate the casinos using our scientific formulas, write the reviews together, and publish them.

7 Factors to Consider To Choose Your Online Casino

Naturally, we use most of these factors to determine our ratings and rankings.

1. Availability in your country

This is an extremely important factor, which most beginners ignore: casinos may not accept players from your country.

In fact, some casinos with a questionable reputation will allow you to register an account and deposit funds but will withhold your winnings and freeze your account forever.

In our list, we use complex algorithms to only display casinos that are available in your country.

You can also change your country anytime you need at the top right of your screen.

2. Trustworthiness

This is another crucial factor.

Many players over time have reported wrongful behaviors from online casinos and have shared complaints online about them.

These complaints range from simple bugs and misunderstandings with support, up to serious accusations against the sites such as withholding winnings and closing players’ accounts without justification.

We use our long-time experience in the gambling industry to assess the trustworthiness of every casino we review, in order to share with you only the best online casinos.

We use at least the following factors to assess the reputation of an online casino:

  • Date founded. The longer the site operates, the safest it is more often than not.
  • Operating company. Some companies run more than one casino. We also check the reputation of these companies.
  • Licenses. If the casino you choose owns solid licenses, it will be easier for you to resolve any issue that may arise.
  • Complaints received. Players regularly post complaints about some casinos. We research online extensively and report back to you.
  • Complaints resolved. Some online casinos care more than others. Some of them publicly resolve online complaints timely, while some other casinos completely ignore them.

3. Player Experience

The best online casinos in 2021 should offer a player experience in line with the time we live in.

However, some casinos present the following issues:

  • Their design makes them look like they have been created in 2002
  • It’s very difficult to navigate them; contact support, find your favorite games, etc.
  • They offer a poor experience on mobile

Some of the best online casinos will also offer cool extra features, such as more protection for your player account, anonymous gaming, and active communities of players with whom you will be able to interact.

Your experience at an online casino should be fun. So make sure it is by choosing a casino that offers a modern gaming experience.

4. Promotions and VIP program

More important than the welcome bonus: the promotions and VIP program (sometimes called “loyalty program”) which casinos offer.

These features often create a more enjoyable experience, which will make you play for longer. A win-win for you and for the casino.

Some casinos will barely offer any promotion apart from their welcome bonus. They may not offer a VIP program or offer one that’s not transparent or interesting enough to keep you incentivized to play.

The best online casinos offer frequent, sometimes exclusive promotions. These will involve tournaments and contests involving more players like you, and more promotions like giveaways, jackpots, and special offers.

The best online casinos also offer incentives for their VIPs, such as a private account manager, dedicated support, faster withdrawals, exclusive events invitations, gifts sent at your home, and more.

We believe that great promotions and VIP rewards represent the future for the best online casinos, and this is why they play an important role in our ratings.

5. Customer Support

As you keep playing at the casino you picked, you will inevitably need to reach out to support.

It may be because you faced an important issue, or it may be because you need to ask simple questions.

But supports at online casinos aren’t created equal.

Some of them offer various types of support, such as live chat, email support and phone support, while the others offer limited support options (i.e. email support only).

Some offer support in your language, some don’t. This can be problematic mostly for non-English native speakers.

Most importantly, the best online casinos dedicate a large budget to their customer service. This implies quick support (a few minutes for live chat and phone help, up to an hour via email), and more importantly, efficient support.

You cannot imagine how often we deal with incompetent support.

Playing on online casinos with great support will significantly enhance your experience.

6. Payments

The best online casinos should offer:

  • Convenient deposits and withdrawal methods.
  • Reasonable weekly/monthly withdrawal limits.
  • Fast payouts.

This is not the case of all casinos out there.

Although we don’t take this aspect into account when rating casinos (because each player has different needs), make sure you choose a casino that offers the payment methods and terms you agree with.

7. And Many More

There are many more aspects to take into account, such as the:

  • Welcome bonus true value.
  • Currencies available at the casino (different from the deposit methods).
  • Casino games and software providers available.
  • Steps and time required to register an account.
  • Need to verify your identity before you withdraw your winnings, and how difficult this process is.

And many, many more.

For more simplicity, just rely on our ratings and rankings. After all, the purpose of our site is to make it easy for you to find reliable and fun casinos (the best online casinos)!
