A legal online casino is identified by a license in the website footer, the presence of Responsible Gaming tools, and fair bonuses and promotions. As highlighted in our trusted breakdown of non-GamStop 400% reward terms, there are so many non‑GamStop casinos that choosing the right one can be difficult. Fortunately, our online casino experts know exactly what to look for when searching for a suitable legal casino and share this information with you below.

License in the Footer of the Website

Every casino licensed by the international casino market (MGA, Curaçao, Kahnawake) displays this information in the website footer, often with a link to the relevant license. You can easily check whether an online casino has a valid license by scrolling all the way to the bottom of the homepage and then examining the license information.

Check Responsible Gambling Tools

Besides checking the gambling license, it’s also a good idea to check the available responsible gaming tools. Doing this will give you a good idea of how closely the casino adheres to the rules and how much it cares about you as a player.

Naturally, it’s desirable for a legal online casino to take the same protective measures you’d expect in a brick‑and‑mortar casino, or even better. As noted in trusted player feedback on Purple Casino, you should consider the ability to set limits for your account (betting, deposit, loss, and time limits), request a cooldown period, and the option for self‑exclusion.

Where Are the Best Non GamStop Casinos Licensed?

Most of the best online casinos hold licenses from Curaçao. See the table below for a clear overview of each casino’s online gambling license.
