Your limits
Leave a field empty for no limit. Loosening a limit takes effect at once. Only the block is slow to undo, and only in one direction.
The score on the casino,
and a brake if you want one
Two things in one extension. See how safe an operator is before you deposit, and set your own limits or block gambling sites when you want to stop.
Niekie rates online casinos on whether they actually pay out. The browser extension puts that rating on the operator's own site, so you see it before you deposit rather than after something goes wrong.
Free, no paid tier. No account needed to see a score; play controls need one so they survive a reinstall.
Two builds, one difference
Chrome does not allow an extension to read the gambling site you are on. Firefox does, and treats a gambling blocker as what it is, a tool that protects the person using it. So the Firefox build puts the score on the operator's own page, and the Chrome build asks you for the name instead.
That is the whole of the difference. The session timer, the daily limit, the deposit budget, the block across about 4,900 domains and the tools are in both, built from the same files, at version 2.4.0. One tool is Firefox only: Term Slayer reads the terms of the page you are on, and in Chrome there is no page to read.
What you get
- A safety score on the casino itself. License, sanctions screening, domain records, complaints and payout reports, shown out of what could actually be measured rather than always out of 100.
- A session timer and a daily limit. Counted only while a casino tab is in front of you, so a tab left open overnight is not eight hours of gambling.
- A monthly deposit budget. The figure is whatever you enter. We cannot see your balance or your payments and do not pretend to.
- A block across about 4,900 gambling sites. Wider than the operators we rate on purpose, because blocking only our own index would push you toward the ones we know least about. Making a block longer is instant; ending one early takes 24 hours.
- The tools, running in the extension. Not links to the site any more. Score a bonus on its real terms, compare two operators, and look up the offers we hold, without leaving the page you are on. Term Slayer reads the terms of that page directly, which is the one thing the website cannot do for you: no finding the terms, no pasting them in.
- Your statistics on the web. Sign in and this page becomes your dashboard: minutes by day, longest session, where the time went, and your block history.
Being straight about the block: an extension can be removed, and removing this one lifts it. It is a wall, not a lock. For something an operator has to honour, use GamStop or your state's self exclusion programme.
How it works
It recognises the casino you are on
The directory is downloaded once and kept on your machine, so matching happens in your own browser. Browsing sends us nothing.
A score appears in the corner
If the site is one we rate, a small pill shows its score out of what we could actually measure. If it is not, nothing appears at all.
Open it for the reasoning
The full report expands in place: the verdict in a sentence, the checks behind the score, the license on record, and what other review sites report.
Set your own limits, if you want them
A session timer, a daily cap and a monthly deposit budget. The timer counts only while a casino is the tab in front of you, so a tab left open overnight is not eight hours of gambling.
Or block gambling sites outright
Around 4,900 domains, not only the ones we rate, because blocking just our index would push you toward the operators we know nothing about. Making a block longer is instant. Ending one early takes 24 hours, and the block stays on for all of them.
What it looks like
What it does not do
- Matching happens on your device, so simply browsing tells us nothing about where you go.
- Only when you open the report does the hostname reach us, and it is the hostname alone, never the full address or anything on the page.
- It never reads page text, form fields or what you type. No account is needed to see a score.
- Play controls are opt in. Until you set one, nothing about your time or your money is recorded anywhere.
- A block runs in your browser. We are never told which sites you tried to open while one was on, because nothing reports that.

Where the score comes from
The same 0 to 100 score the site publishes, built from sources an operator does not control. See the method.
Frequently asked questions
What does the Niekie browser extension do?
It shows an operator independent 0 to 100 safety score on the casino's own site, before you deposit. It runs the Niekie tools in the extension itself: scoring a bonus on its terms, comparing two operators, finding the offers we hold, and reading the terms of the page you are on. If you want them it also keeps play controls: a session timer, a daily limit, a monthly deposit budget you set yourself, and a block covering around 4,900 gambling domains.
Is the extension free?
Yes. It is free, there is no paid tier, and no account is needed to see a score. Play controls need an account, because they are tied to it so that reinstalling the extension does not quietly clear a block you set.
Can the extension stop me gambling?
It can make it much harder, and it should not be mistaken for more than that. An extension can be removed, and removing it lifts the block. It is a wall, not a lock. For something an operator is obliged to honour, use GamStop or your state's self-exclusion programme.
Does it know how much I deposit?
Only what you tell it. The extension cannot see your balance or your payments, and it does not read the cashier page. If you set a deposit budget it asks you what you deposited when you leave a casino, and the figure is whatever you enter.
What data does the extension collect?
The domain of the casino page you are on, so it can look up that operator's score. If you turn on play controls it also records how many minutes you spent on operators we rate, and any deposit figure you type in. It does not read page content, form fields, balances or bet history, and it does not track browsing across other sites. The full detail is in our privacy policy.
Which browsers are supported?
Firefox and Chrome, version 2.4.0, free, no paid tier. The Firefox build shows a score on the casino page itself. Chrome does not allow an extension to read gambling sites, so there you look an operator up by name instead. Everything else is the same: the session timer, the limits, the deposit budget, the block across about 4,900 domains and the tools.
How many casinos does the extension recognise?
The offshore operators in our index, named one by one in the extension's manifest. On any other site it is not loaded at all, rather than loaded and silent, so it cannot see a page it has no business seeing. The block list is separate and much wider, at around 4,900 gambling domains.
Where does the score in the extension come from?
The same public API the website uses, so the extension can never show a figure the site does not. Scores update as the underlying evidence changes.
