About us

Who we are

TopSlotsOnlineCasinos is an independent comparison site: we test slot machines, providers and online casinos from the player's point of view. We do not operate a casino, and we do not accept money for a better rating. The content is written by the editorial team, with our own accounts and our own deposits – if we haven't tried something, we don't write about it.

The core of the team is three people. Two testers who have played online since 2016, and an editor who keeps the texts, the numbers and the updates in hand. Alongside them, an external developer looks after the site.

What we do differently

Most comparison sites rank by the size of the bonus. We look at other things:

  • Withdrawals in practice – we request a real withdrawal and measure how long it takes to arrive.
  • Terms, not headlines – we weigh the wagering requirement, the maximum bet and the deadline together.
  • Convenient currencies and support – accounts in euros without conversion fees, with responsive customer service.
  • Demo mode – we play through every slot without registration too, and make the demo available on the site as well.

How we rate

Casinos are scored on a 10-point scale, based on five weighted criteria:

  1. Licence and security (20%)
  2. Bonuses and their real terms (25%)
  3. Game selection and providers (20%)
  4. Deposits, withdrawals and speed (25%)
  5. Customer support and availability (10%)

With slot machines, what counts is the RTP, the volatility, the maximum win and the bonus mechanics – taken from the developer's official data, not from hearsay.

How the site is funded

The site contains affiliate links: if you register through them, the casino pays us a commission. This costs the player nothing and does not influence the ratings – the ranking is built from the tests, and the size of the commission is not a factor. We write up the negative experiences too.

Updates and error reports

Bonus terms and payment limits change often. We review the casino pages quarterly and the bonuses monthly. If you spot a discrepancy, let us know on the Contact page – fixes are typically made within 48 hours.

If you are under 18, the content of this site is not for you. Gambling carries risks – on the responsible gambling page we've collected what to watch out for.
