Gambling Category - Web Filtering Database | Block Online Gambling Domains

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. Our classification engine tracks these relationships, ensuring that when an operator is classified, their entire domain portfolio is identified, including newly registered mirror domains.

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. Our database tracks the primary domains, payment portals, game servers, and CDN domains associated with each casino operation.

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.

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.

Our API tracks operator relationships across their entire domain portfolio. When one domain is classified, all related domains operated by the same entity are identified. This includes promotional microsites, affiliate landing pages, payment processing domains, and mobile-specific variants.

For ISPs implementing regulatory blocking orders, our feeds include metadata identifying the gambling operator behind each domain. This enables compliance reporting that documents which specific operators are being blocked, satisfying regulatory audit requirements.
