GUIDE: How to check if a casino hosts REAL slots or pirate copies (lower RTP ris

[NewCryptocasinos]

Most players assume that if a slot has a well-known name (Hacksaw, Pragmatic, Nolimit, etc.), it must be real.

That’s not always true.
Some casinos host copied / self-hosted slot files, which allows them to:

Lower RTP

Change hit frequency

Control payouts without audits


The good news: you can check this yourself in 1–2 minutes.
No special tools needed — just your browser.

Below is a simple step-by-step guide.

🛠 What you need

Desktop browser (Chrome / Brave / Firefox)

Any casino

A well-known slot (the example below uses Wanted: Dead or a Wild by Hacksaw Gaming).
This is how it should look — you can clearly see that the game data is loaded directly from Hacksaw Gaming’s infrastructure, confirming it’s the original game.



✅ STEP 1: Open a well-known slot

Choose a slot from a major provider:

Hacksaw Gaming

Pragmatic Play

Nolimit City

Play’n GO, etc.

Avoid “exclusive” or in-house games for this test.

✅ STEP 2: Open Developer Tools

While the slot is open:

Press F12

Or right-click → Inspect

Go to the Network tab

Select Fetch / XHR

Reload the page (important)

✅ STEP 3: Look at WHERE the game loads from (most important)

Now look at the Network request list.

✔ What a REAL slot looks like

You should see requests going to the provider’s infrastructure, for example:

hacksaw-casino.com

pragmaticplay.net

nolimitcity.com

In the attached screenshot, notice files like:

authenticate

version.json

dependencies.json

desc-locale.json

All initiated by Hacksaw Gaming domains, not the casino.

➡ This means:

The casino does NOT control the RNG

The casino does NOT control RTP

The game is provider-hosted and audited

This is a fresh information since I don’t have technical knowledge to verify what casino offers especially 3rd party slot game provider.

However, most reputable casino will less likely cheat by copying game provider but I will note on this method when trying new casino. I’m waiting for fellow member with background on this matter to verify the method.

Yes, this method can help verify the authenticity of the slot game and reduces the chances that it is a copied
version. When checking the requests in the browser’s developer tools, always make sure to verify the domain name to which the reqests are being send and from which the responses come belongs to the official game provider and watch out for misspellings.
In some cases, when you open a slot game, you will be redirected to the game provider’s domain and you can verify this directly from your browser’s address bar so you don’t need to use the browser’s developer tools.

I been reading and see the discussioon of pirates or copy slots from my local podcast youtube.

My only question, is these check is real ? do you @OP write these based on your experience or not. Or you just copy these from AI and posted it... I mean mostly prefer a resource are coming from experience not AI to be honest.

If you ask me, yes there has some pirates slot. The only question is is these way legits to check ? can someone maybe the one who programmer or slot expert can confirm these is the way to check ?

I haven't made such a test ever but it makes sense. Btw this is an easy guide for me, who has been using developer tools but it might be hard for a complete newbie, so I suggest you to create a quick video tutorial where you'll show it step by step. Then it will be very easy for everyone to check it.
Btw what about lottery? If slot is self-hosted, can it have the same lottery as the real slot? I think that one of the easiest way to check whether slot is authentic or not, is to check what the official jackpot is from the official provider and then compare it to the hosted slot on the casino's website.

You're exactly right. A self-hosted slot is "air-gapped" from the official network. It cannot tap into the global prize pool because the official provider (like NetEnt or Relax) hasn't authorized that server.

If the official jackpot is €1.2M but the casino version is stuck at €50k, it’s a obvious fake.
