What the Gambling Category Covers

The Gambling category in our web filtering database classifies domains that offer, promote, or facilitate real-money wagering activities. This includes traditional online casinos and sportsbooks, but also extends to the rapidly growing sectors of cryptocurrency gambling, fantasy sports with entry fees, prediction markets, and social casino games that can function as gateways to real-money gambling.

Gambling domains are particularly challenging to classify because the industry operates across many jurisdictions with different legal frameworks. A site legal in one country may be prohibited in another. Our classification focuses on identifying gambling activity rather than legality, providing the domain intelligence that allows organizations and ISPs to enforce their own policies based on local regulations.

The gambling domain landscape is highly dynamic. Operators frequently rotate domains to evade blocks, use mirror sites under different TLDs, and deploy promotional microsites for specific events. Every new domain is categorized from its own content, and each newly registered domain is checked again after a week and after a month.

Block gambling by category and cut off new sites as they appear

Operators launch new domains constantly, which is why hand-made lists leak. The managed filter blocks the Gambling category per site, so a new casino is covered once it is labelled.

Gambling Domain Types

Our classification covers the full spectrum of online gambling activities and platforms

Online Casinos

Web-based casino platforms offering slots, table games, live dealer experiences, and progressive jackpots. Includes both licensed operators and unlicensed offshore platforms, along with the cashier and payment pages that belong to them.

Sports Betting

Sportsbooks and betting exchanges covering traditional sports, esports, and novelty betting markets. Includes pre-match and in-play betting platforms, odds comparison sites, and tipster services that link directly to betting operators. The sports betting sector has the highest domain turnover rate in the gambling category.

Lottery & Bingo

Online lottery ticket sales, number draw games, scratch cards, and bingo platforms. Includes both official state lottery websites and third-party lottery betting services that allow wagering on lottery outcomes. Our classification distinguishes between informational lottery sites and those that facilitate actual ticket purchases or wagers.

Crypto Gambling

Blockchain-based gambling platforms accepting cryptocurrency deposits, provably fair games, decentralized casinos, and NFT gambling. This rapidly growing subcategory includes both dedicated crypto casinos and traditional operators that have added cryptocurrency support. Many operate without traditional licensing, making domain-level blocking essential.

Poker & Skill Games

Online poker rooms, real-money skill game platforms, and competitive gaming sites with cash prizes. Includes ring games, tournament platforms, and sites offering games of skill like fantasy sports with entry fees. Classification accounts for the blurred line between skill-based gaming and gambling in various jurisdictions.

Prediction Markets & Binary Options

Platforms allowing wagers on event outcomes, binary options trading sites classified as gambling by regulators, and prediction markets. Includes political betting markets, weather betting, and platforms that blur the line between financial trading and gambling through their product structure.

Global Regulatory Landscape

Online gambling regulation varies dramatically between jurisdictions. In some countries, all online gambling is prohibited. In others, specific forms are licensed while unlicensed operators are blocked. ISPs in countries including Italy, France, Spain, Australia, and many Asian nations are required to block access to unlicensed gambling domains.

Our gambling category provides the raw domain classification that ISPs and organizations need to implement jurisdiction-specific blocking policies. Rather than making legal determinations, our API returns gambling domain classifications with subcategory detail, allowing your filtering infrastructure to apply the appropriate policy for your jurisdiction.

For organizations supporting self-exclusion programs, our API enables voluntary gambling blocks that help individuals managing problem gambling behavior. When integrated with parental control software, it prevents minors from accessing gambling platforms that may have inadequate age verification. Gambling is also routinely blocked by every K-12 web filter for school districts managing student devices.

Filtering Use Cases

Gambling filtering serves diverse needs across sectors and regulatory environments

Education Networks

Schools and universities block gambling sites to maintain appropriate learning environments and comply with acceptable use policies. Students accessing gambling platforms on school networks face both disciplinary and financial risks that educational institutions have a duty to prevent.

Gambling blocked under the school internet safety policy
Covers social casino games popular with students
Blocks esports and fantasy sports betting platforms
Prevents access during exam periods to reduce distraction

Workplace Policies

Employers block gambling sites to prevent productivity loss, reduce insider threat risk from financially compromised employees, and maintain professional workplace standards. Financial services firms have additional regulatory obligations to prevent gambling activity on company networks.

Productivity protection during work hours
Financial services compliance requirements
Insider threat risk reduction
Bandwidth management for streaming gambling content

ISP Regulatory Compliance

Internet service providers in regulated markets must block access to unlicensed gambling operators. Our database provides the domain intelligence ISPs need to comply with gambling authority blocking orders while allowing access to licensed operators approved by local regulators.

Effective Gambling Domain Blocking

Gambling operators are among the most aggressive in evading domain blocks. They use domain rotation, mirror sites, VPN-friendly redirects, and app-based access to circumvent DNS-level filtering. Effective blocking requires comprehensive domain coverage combined with frequent updates to catch new evasion domains.

Each mirror, promotional microsite and affiliate landing page is categorized from its own content, so a new address gets the Gambling label as soon as it shows gambling content. Newly registered domains are checked again after a week and after a month.

ISPs that must follow regulatory blocking orders combine the official list from their regulator with the category. The category helps them spot new mirror domains to review, while the regulator's list stays the legal basis for the block.

List of gambling sites, by type

Gambling Website List: What Each Type Includes

The Gambling category is one label, but the sites behind it are very different. This table shows what each type covers and which second category it often carries, so you can write a policy that matches your users.

Type	What it covers	Often also tagged	Policy note
Online casinos	Slots, roulette, blackjack, live dealer tables, jackpot games, casino payment and cashier pages.	Gambling	Blocked in schools, most workplaces and every regulated ISP list for unlicensed operators.
Sportsbooks	Pre-match and in-play betting, betting exchanges, esports betting, odds pages that take bets.	Sports & Recreation	Watch for event microsites that appear before big tournaments.
Poker	Real-money poker rooms, tournament lobbies, poker client download pages.	Gaming	Poker training and strategy sites without wagering usually rank Gaming first.
Lotteries	Official lottery ticket sales, lottery betting on foreign draws, scratch cards, online bingo.	Government & Legal	Results-only pages and state lottery news are a common allow exception.
Crypto gambling	Casinos and dice games that take coins and tokens, crash games, on-chain betting.	Cryptocurrency	Frequently unlicensed; block both Gambling and, where policy allows, Cryptocurrency.
Social casinos	Free-to-play slots and casino games with virtual coins, sweepstakes-style casino play.	Gaming	A deliberate policy choice: youth policies usually block them, adult workplaces may not care.
Betting tips and affiliates	Tipster sites, bonus code pages, casino review and comparison sites that send traffic to operators.	Advertising/MarketingBlogs/Personal Sites	They do not take bets, but they exist to start them. Most strict policies block them too.

Every domain can carry several categories, ranked by how much of the site they describe. A sports news site with a betting widget keeps News/Media first, so you can decide whether a lower-ranked Gambling tag should trigger a block. See the full list of web filtering categories.

Why a static gambling blocklist goes stale

How Gambling Sites Hide From Filters

Operators that are blocked in a market keep looking for new ways in. These are the patterns that make a one-off gambling domains list out of date within weeks. The examples are placeholders, not real sites.

Mirror domains

The same casino is served from a chain of near-identical addresses. When one is blocked, players are pointed to the next one by email, chat groups or a redirect page.

casino-example7.test → casino-example8.test → casinoexample-mirror.test

How the list handles it: each mirror is categorized from its own content, so the new address gets the Gambling label as soon as it is live, not when someone reports it.

Newly registered domains

Many gambling domains are registered weeks before they open. On day one they show a blank page or a holding message, then switch to a full casino later.

bet-example-cup.test (registered) → empty page → sportsbook goes live

How the list handles it: about 300,000 new domains are categorized daily, and each one is checked again after a week and after a month, which is when many of them add their content.

Affiliate review sites

Review, bonus and "top casinos" pages carry no games, so a filter that only looks for betting slips misses them. Their job is to send visitors to an operator.

best-casino-bonus-example.test/review/

How the list handles it: sites whose main purpose is promoting gambling are included in the category, with a second tag that shows they are promotional.

Redirect and landing domains

Short-lived landing pages sit between an ad or a message and the real casino. The visible link changes often while the destination stays the same.

promo-example-go.test → casino-example7.test

How the list handles it: landing pages that exist only to forward to gambling are labelled; general VPN and proxy domains used to dodge blocks sit in their own category.

Sites that keep moving

New gambling domains handled on the policy level

Because the block is a category switch, new labelled domains follow the rule without an edit. Always-block entries cover anything you want to stop right now.

Why organisations block gambling websites

Regulation, Schools and Workplaces

The reasons to block gambling websites differ by sector. The rules change often and differ by country, so treat this as a general picture and check the current guidance for your market.

Regulated markets and ISPs

Many countries license online gambling and require internet providers to block operators without a local licence.

The regulator usually publishes the official list of blocked operators
ISPs add a category list to spot new mirrors for review
Some markets also restrict advertising and affiliate sites
Records of what was blocked and when help with audits

Schools and libraries

Gambling is not one of the three items CIPA names, but school internet safety policies almost always block it for students.

Blocked by default in school filters and on managed devices
Social casinos and betting tips are usually blocked as well
Lottery results pages are a common teacher request
See CIPA web filtering for the full picture

Workplaces

Employers block gambling under their acceptable use policy, for productivity and to keep company devices and payment cards away from betting sites.

Banks and trading firms often apply stricter rules
Guest Wi-Fi and staff networks may get different policies
Sports news stays open while betting is blocked
More on web filtering software for business

What the category does not do: it does not decide whether a site is legal where you are. It tells you that a domain offers or promotes gambling, and your policy, or the regulator's list, decides what happens next.

Gambling blocklist in practice

How Vendors and ISPs Use the Gambling Domains List

The database is delivered as files that run inside your own systems. The usual path from download to a working block looks like this.

Load the file

Import the CSV, Parquet or JSON file into your product, or take a ready export such as DNS RPZ, a hosts file or a firewall external dynamic list.

Map the category

Point the Gambling label at your own policy category.

Apply daily deltas

Add the daily delta file of newly categorized domains so new mirrors are covered. All other domains are refreshed monthly.

Look up the rest

Use the lookup API included with the licence for anything not yet in your local copy, or test a single address with the domain lookup tool.

Firewall and gateway makers

Ship Gambling as a ready policy category in the appliance or cloud gateway, with the data held on the box or in their own cloud.

DNS filtering services

Answer gambling lookups with a block page or no answer. The DNS filtering vs web filtering guide covers the trade-offs.

ISPs and telecom groups

Combine the regulator's list with the category to find new mirrors and to offer opt-in family filters to subscribers.

Self-exclusion and parental apps

Block every type in the table, including affiliates, so a person trying to stop does not land on a bonus page. See the parental control app category database.

Questions

Gambling Domains List: Frequently Asked Questions

What is a gambling domains list?

A gambling domains list is a set of website domains whose main content is real-money wagering or its promotion: online casinos, sportsbooks, poker rooms, lotteries, crypto gambling and betting tip sites. Filtering products load the list into a policy so the whole category can be blocked or allowed with one rule.

How do I block gambling websites on a network?

Block the Gambling category in your firewall, DNS filter or secure web gateway. If you build the filter yourself, load a gambling blocklist into your DNS resolver as a response policy zone, or into your firewall as an external dynamic list, and refresh it every day so new mirror domains are covered.

Does the list separate licensed and unlicensed gambling sites?

The category describes what a site does, not whether it holds a licence in a given country. Licensing differs by jurisdiction and changes over time, so ISPs and regulators combine the category with their own official list of licensed or blocked operators.

Are social casinos and betting tip sites included?

Yes. Casino-style social games and betting tip or affiliate review sites are covered, and they often carry a second category such as Gaming or Sports & Recreation. That lets a policy block real-money wagering while making its own choice about the borderline sites.

How quickly are new gambling domains added?

About 300,000 newly registered domains are categorized every day and delivered as daily delta files. Each new domain is checked again after a week and after a month, which catches mirror domains that go live some time after registration.

Do schools have to block gambling sites?

CIPA itself targets visual depictions that are obscene, child pornography or harmful to minors, so gambling is not one of the three named items. In practice almost every school internet safety policy blocks gambling as well, and school filter vendors ship it blocked by default.

Can we put the gambling list into a product we sell?

Yes, with an OEM licence. The data can be embedded in a firewall, DNS filter, parental control app or self-exclusion tool. Resale or publication of the raw domain list is not permitted. Read more about OEM licensing.

Prices follow the count of sites and devices, so a short list of both is all we need. A pilot on one site lets you check the blocks and reports before anything is agreed.
