Donbet Casino Review 2026: Bonuses, Games and Licence Check

Donbet Casino has been operating in the UK-facing market since its launch in 2021, though its primary licence comes from the Curaçao Gaming Control Board rather than the UK Gambling Commission. That distinction matters more than most players realise, and it shapes everything from deposit protections to dispute resolution. This review breaks down what Donbet actually offers in 2026, where it falls short, and whether the maths of its bonus structure works in your favour.

Licensing and Regulatory Status of Donbet Casino

Donbet Casino operates under a Curaçao eGaming licence (number 8048/JAZ2020-013), which was renewed in 2024 and remains valid through 2026. The operator is registered to N1 Interactive Ltd, a company incorporated in Malta that manages several casino brands. This structure is common among offshore operators, but it creates a specific set of legal realities for UK players that deserve attention before you register.

The UK Gambling Commission does not recognise the Curaçao licence as equivalent to its own standards. That means Donbet is not listed on the UK's official white list of approved operators, and UK players who choose to join are not covered by the Commission's dispute resolution service. The practical difference shows up when problems arise: complaints go through Curaçao's process, which historically resolves fewer disputes than the UK system.

What does the Curaçao licence actually cover in 2026?

The Curaçao licence permits Donbet to offer casino games, live dealer tables and sports betting across most international markets. It does not authorise operations in the United Kingdom, the United States, France, Spain, or Australia. For UK residents, this creates a grey area where the casino accepts registrations but operates without explicit UK regulatory approval.

Licensed operators under Curaçao's regime must submit to annual compliance reviews covering anti-money laundering (AML) procedures, responsible gambling tools and technical audits of their random number generators. These checks happen through third-party firms approved by the Curaçao Gaming Control Board, though the frequency and depth of testing are less rigorous than the UK's quarterly reporting cycle.

Why does the absence of a UK Gambling Commission licence matter?

UK-licensed casinos must contribute 0.1% of gross gaming yield to GambleAware, participate in the multi-operator self-exclusion scheme GAMSTOP, and verify every player's identity before any withdrawal. Donbet does none of these. Players who want to self-exclude from all UK casinos at once cannot use GAMSTOP here; they must contact Donbet directly and request account closure.

The UKGC also caps maximum stakes on online slots at £5 per spin for players aged 18 to 24. Curaçao-licensed sites face no such limits. If you are a younger player, the protections you receive from a UK-licensed operator simply do not exist at Donbet, and the burden of managing your own limits shifts entirely onto you.

Donbet Casino Bonuses and Promotions in 2026

Donbet's welcome package currently offers a 100% match bonus up to €300 plus 100 free spins on the slot Book of Dead, spread across your first three deposits. The minimum qualifying deposit is €20, and the wagering requirement sits at 35 times the bonus amount. For a €100 deposit, that means you must wager €3,500 before any winnings from the bonus become withdrawable.

Beyond the welcome offer, Donbet runs a weekly reload bonus every Monday worth 50% up to €200, and a weekend cashback scheme that returns 10% of net losses up to €500. The cashback is credited as bonus funds with a 10x wagering requirement, which is notably lower than the industry average of 25x to 40x for similar promotions.

How do Donbet's wagering requirements compare to UK operators?

UK-licensed casinos rarely offer wagering requirements below 20x on bonus funds, with many landing between 25x and 40x. Donbet's 35x requirement sits at the higher end of that range. However, the calculation method differs: UK operators typically exclude certain games from contributing to wagering, while Donbet applies a flat contribution rate where slots count 100%, table games count 10%, and live dealer games count just 5%.

That contribution structure effectively makes live blackjack and roulette unplayable with bonus funds unless you enjoy grinding 700x your bonus through a game that only counts 5%. Slots players get a fairer deal, but the 35x requirement still demands patience and a reasonable bankroll to clear within the 7-day validity period.

Which games contribute fully to bonus wagering at Donbet?

Slots from Pragmatic Play, NetEnt, Microgaming and Hacksaw Gaming contribute 100% towards wagering requirements. Classic table games like blackjack and roulette contribute 10%, while live dealer tables from Evolution Gaming contribute only 5%. Video poker and progressive jackpot slots contribute 0%, meaning any spins on those games with active bonus funds do not count toward clearing your requirement.

This structure is standard for offshore operators but creates a trap for casual players. If you deposit €50, claim the €50 bonus, and play a few hands of live blackjack, you will clear only €5 of wagering per €100 staked. The 35x requirement suddenly becomes a 700x mountain, and most players abandon the bonus long before completion.

What are the maximum withdrawal limits on bonuses?

Donbet caps winnings from bonus funds at 10 times the original bonus amount. A €100 bonus therefore has a maximum cashout of €1,000, with any excess removed during the withdrawal review. This cap applies per bonus claim, not per deposit, so stacking multiple bonuses does not increase your ceiling unless each bonus clears independently.

Free spin winnings carry a separate cap of €100 per batch of spins. If you win €500 from your 100 free spins on Book of Dead, only €100 becomes withdrawable. This detail hides in the terms and conditions rather than the promotional page, and it significantly reduces the expected value of the welcome offer for players who hit a lucky streak.

Game Selection and Software Providers at Donbet Casino

Donbet hosts over 4,500 casino games from 60+ software providers, placing it comfortably among the larger offshore libraries. The portfolio includes slots, table games, live dealer rooms and a dedicated section for crash games. Pragmatic Play, NetEnt, Microgaming, Play'n GO and Evolution Gaming anchor the collection, with Hacksaw Gaming, Nolimit City and Push Gaming adding variety for players who prefer modern mechanics.

The slots lobby organises games by provider, popularity and volatility, which helps when you are hunting for a specific title. Search functionality works well, and the filter system lets you sort by return-to-player percentage, bonus buy availability and jackpot size. Live dealer games stream in HD from Evolution's studios, with dedicated tables for UK-facing players during peak evening hours.

Which live dealer games does Donbet offer?

Evolution Gaming supplies the full live casino suite, including Infinite Blackjack, Lightning Roulette, Crazy Time and Monopoly Live. Table limits start at £0.20 for roulette and rise to £10,000 for high-stakes baccarat. The live lobby also features game shows like Sweet Bonanza Candyland and Funky Time, which have become increasingly popular among UK players since 2024.

Donbet does not currently offer live dealer tables from Playtech or Pragmatic Play, which narrows the variety compared to multi-provider rivals. Evolution's dominance means you get consistent quality, but players who prefer Playtech's Quantum Roulette or Pragmatic's Speed Blackjack will not find those specific tables here.

What are the top slot titles available at Donbet?

Popular titles include Sweet Bonanza from Pragmatic Play, Starburst XXXtreme from NetEnt, and Book of Dead from Play'n GO. Hacksaw Gaming's Chaos Crew II and Nolimit City's Mental have strong followings among players who appreciate high volatility. Progressive jackpot hunters can access Mega Moolah from Microgaming, though the jackpot pools on this network have been smaller than their peak in 2023.

Bonus buy slots are available for titles that support the feature, including many from Hacksaw Gaming and Nolimit City. The minimum bonus buy price starts at £0.20, with some games offering buys up to £200. Donbet does not restrict bonus buys on its own platform, which distinguishes it from UK-licensed operators that often exclude these features from bonus wagering entirely.

How fast are withdrawals processed at Donbet Casino?

Donbet processes withdrawal requests within 24 hours for all payment methods, which is faster than the 48 to 72 hours common at UK-licensed casinos. However, the speed of your actual payout depends entirely on the method. E-wallets like Skrill and Neteller typically arrive within 24 hours of approval, while bank transfers take 3 to 5 business days and card withdrawals take 5 to 7 business days.

Cryptocurrency withdrawals process almost instantly, usually within 10 to 30 minutes of approval. Donbet supports Bitcoin, Ethereum, Litecoin and Tether, and crypto deposits receive a 5% bonus boost up to €150. The minimum withdrawal for fiat methods is £20, while crypto withdrawals start at the equivalent of £10.

Payment Methods, Fees and Currency Support at Donbet

Donbet accepts Visa, Mastercard, Skrill, Neteller, Paysafecard and a range of cryptocurrencies. The casino does not charge deposit fees, but withdrawal fees apply to certain methods. Bank transfers incur a flat fee of £2.50, while card withdrawals carry a 1.5% processing charge capped at £10. E-wallet and crypto withdrawals are free of charge.

All deposits are instant, with no upper limit on card transactions provided your bank approves the payment. The minimum deposit for fiat methods is £10, though the welcome bonus requires £20 to qualify. Donbet also offers a dedicated VIP team for players who deposit over £1,000 per month, with personalised withdrawal limits and a dedicated account manager.

Does Donbet charge currency conversion fees for UK players?

Donbet operates primarily in euros, which means UK players depositing in pounds sterling face a currency conversion at the payment processor level. The exchange rate applied typically includes a 2% to 3% margin above the interbank rate, effectively adding a hidden fee to every deposit and withdrawal. Players who fund their accounts in euros or cryptocurrency avoid this entirely.

This conversion cost is not disclosed prominently on the website. It appears only in the payment terms section, buried several pages deep. Over a year of regular play, a player depositing £200 monthly could lose £48 to £72 in conversion margins alone, a cost that UK-licensed casinos operating in pounds sterling do not impose.

What is the maximum withdrawal limit per transaction?

Standard players can withdraw up to £2,000 per transaction, with a monthly cap of £10,000. VIP players at Silver level or above receive increased limits of £5,000 per transaction and £25,000 monthly. The highest tier, Black VIP, can withdraw up to £20,000 per transaction with no stated monthly maximum.

Withdrawals are batched for review, and Donbet requires identity verification before processing the first withdrawal. The KYC process demands a government-issued ID, a proof of address dated within the last 3 months, and a photo of the payment method used for deposits. Verification typically completes within 24 hours, though incomplete documentation can stretch the process to 3 or 4 days.

KYC, AML Procedures and Player Protection at Donbet

Donbet's KYC procedures align with Curaçao's anti-money laundering requirements, which mandate identity verification for all players before withdrawals exceed €2,000 in a rolling 30-day period. In practice, Donbet applies this threshold more conservatively, requesting verification documents once cumulative deposits reach £500 or at the first withdrawal request, whichever occurs first.

The AML framework requires Donbet to monitor transactions for suspicious patterns, report any transaction above €10,000 to the Curaçao Financial Intelligence Unit, and maintain records for at least 5 years. Donbet also conducts regular audits of its random number generators through independent testing agencies, with certification from iTech Labs renewed annually since 2022.

What responsible gambling tools does Donbet provide?

Donbet offers deposit limits, loss limits, session time reminders and a self-exclusion option. Deposit limits range from £10 to £50,000 per day, and players can adjust them with immediate effect for decreases or a 24-hour cooling-off period for increases. Self-exclusion periods run from 24 hours to 6 months, with permanent closure available upon request.

These tools fall short of UK standards in one critical area: Donbet does not participate in GAMSTOP, the UK's multi-operator self-exclusion scheme. Players who self-exclude from Donbet remain active at every other casino they have joined, and the responsibility for tracking exclusions across multiple sites rests entirely with the player.

Where can UK players find help for problem gambling?

GamCare operates the National Gambling Helpline at 0808 8020 133, available 24 hours a day, 7 days a week. The service is free, confidential and staffed by trained advisors who can provide immediate support and referral to treatment services. Players can also access live chat support through the GamCare website or visit the NHS National Problem Gambling Clinic for specialist treatment.

Players who want to block themselves from all UK-licensed gambling sites can register with GAMSTOP at gamstop.co.uk. The service is free and covers over 200 operators, with exclusion periods of 6 months, 1 year or 5 years. Donbet's absence from this register means UK players must manage their exclusion manually, so setting a personal reminder to review gambling habits monthly is a practical safeguard.

Donbet Casino vs UK-Licensed Alternatives: Key Comparisons

The gap between Donbet and UK-licensed operators shows up clearly in player protections, dispute resolution and currency handling. For players who value regulatory oversight above all else, UK-licensed casinos like Bet365 Casino, William Hill Casino and 888 Casino offer the full suite of UKGC protections. Each of these operators contributes to GAMSTOP, undergoes quarterly compliance audits and resolves disputes through the Independent Betting Adjudication Service.

The trade-off appears in game variety and bonus generosity. UK-licensed casinos carry smaller libraries of around 2,000 to 3,000 games, and their bonus wagering requirements often exclude live dealer games entirely. Donbet's 4,500+ game library and more flexible bonus structure appeal to players who want variety and are comfortable managing their own protections.

How do Donbet's protections compare to Bet365 Casino and William Hill Casino?

Bet365 Casino and William Hill Casino both operate under UKGC licences, meaning they participate in GAMSTOP, cap deposits for players under 25, and offer dispute resolution through IBAS. Donbet offers none of these protections. However, both UK operators apply wagering requirements of 20x to 30x on bonuses, compared to Donbet's 35x, and neither offers cryptocurrency deposits.

Transaction speed favours Donbet, with 24-hour withdrawal approvals versus the 48 to 72 hours common at Bet365 and William Hill. But UK operators process withdrawals in pounds sterling with no conversion fees, while Donbet's euro-based system costs UK players roughly 2% to 3% per transaction. For a player depositing £500 monthly, that difference amounts to £120 to £180 annually.

Which operators offer better live casino experiences?

888 Casino and Betway Casino both offer live dealer suites from Evolution Gaming alongside tables from Playtech and Pragmatic Play. Donbet offers only Evolution tables, which limits variety but ensures consistent streaming quality. Sky Vegas Casino and Ladbrokes Casino provide UK-specific live tables with dedicated dealers, something offshore operators rarely match.

For players prioritising live dealer variety, UK-licensed operators like Grosvenor Casinos and Unibet Casino offer the broadest selection. Grosvenor streams from its own UK studios, while Unibet carries multiple providers. Donbet's single-provider approach keeps things simple but leaves players without access to Playtech's Quantum series or Pragmatic's Speed tables.

What do players say about Donbet's withdrawal process?

Player reviews across independent forums consistently praise Donbet's withdrawal speed once verification completes, with most e-wallet payouts arriving within 24 hours of approval. Complaints centre on the KYC process, particularly the requirement to photograph payment cards and provide bank statements. Some players report verification delays of 3 to 5 days when documents are rejected for poor image quality.

CasinoMeister and similar review platforms rate Donbet at 3.5 out of 5 stars, citing the Curaçao licence and lack of GAMSTOP as the primary weaknesses. The operator's complaint response time averages 2 business days, which compares favourably to the industry norm of 5 to 7 days. Donbet's live chat support operates 24/7 with average response times under 2 minutes.

Donbet Casino Bonuses in Detail: Terms, Limits and Fine Print

The welcome package at Donbet splits across three deposits: 100% up to €100 plus 50 free spins on the first deposit, 50% up to €100 on the second, and 50% up to €100 plus 50 free spins on the third. Each bonus carries a 35x wagering requirement, and the free spins come with a separate 40x requirement on any winnings. The entire package must be claimed within 30 days of registration.

Weekly promotions rotate between reload bonuses, cashback offers and free spin giveaways. The Monday reload offers 50% up to €200 with a 25x wagering requirement, while the Wednesday free spins promotion grants 20 spins on a selected slot with no deposit required. Weekend cashback returns 10% of net losses as bonus funds, capped at €500, with a 10x wagering requirement.

What are the most restrictive terms in Donbet's bonus policy?

The 10x maximum cashout on bonus winnings is the most significant restriction, capping your profit potential on any bonus claim. The 7-day validity period for wagering also pressures players into faster play, which increases the statistical likelihood of losing before clearing the requirement. Free spin winnings cap at €100 per batch, regardless of the actual win amount.

Donbet excludes certain payment methods from bonus eligibility. Deposits made via Skrill or Neteller do not qualify for the welcome bonus, a policy designed to prevent bonus abuse through instant e-wallet cycling. Players using these methods must deposit via card, bank transfer or cryptocurrency to activate the promotional offer.

How does Donbet's VIP programme reward regular players?

Donbet's VIP programme spans 5 levels, starting at Silver and progressing through Gold, Platinum, Diamond and Black. Points accrue at a rate of 1 point per €10 wagered on slots and 1 point per €50 wagered on table games. Silver level unlocks at 1,000 points, while Black level requires 100,000 points accumulated within a 12-month rolling period.

Benefits scale with level: Silver offers 5% weekly cashback and a personal account manager, while Black provides 15% cashback, exclusive tournament invitations, and withdrawal priority processing. VIP players also receive custom bonuses tailored to their play patterns, though these offers carry their own wagering requirements that typically range from 20x to 30x.

Are there any no-deposit bonuses available at Donbet?

Donbet occasionally runs no-deposit promotions for new players, typically offering 20 to 50 free spins on a selected slot without requiring a deposit. These offers appear irregularly and usually require a bonus code, which Donbet distributes through its newsletter and social media channels. The wagering requirement on no-deposit free spins sits at 50x, higher than the standard 35x.

Players who receive no-deposit free spins face a maximum cashout of £50 from any winnings. The bonus code must be entered within 48 hours of receipt, and the free spins expire after 72 hours. These promotions serve as a low-cost introduction to the platform, but the restrictive terms make them more of a taster than a meaningful profit opportunity.

Donbet Casino Mobile Experience and Platform Performance

Donbet operates as a mobile-first platform, with a responsive website that adapts to screens from 320px to 4K resolutions. The casino does not offer a native app for iOS or Android, instead directing players to the browser-based version. This approach eliminates app store restrictions and allows instant play without downloads, though it sacrifices push notifications and biometric login features.

Page load times average 1.8 seconds on 4G connections and 0.9 seconds on 5G, placing Donbet in the top quartile of casino platform performance. The game lobby uses lazy loading to display thumbnails progressively, and the search function returns results in under 200 milliseconds. Live dealer streams maintain 60 frames per second at 1080p resolution on stable connections.

Which games perform best on mobile at Donbet?

Slots from Pragmatic Play and NetEnt are fully optimised for touch controls, with portrait and landscape orientations supported. Hacksaw Gaming titles use HTML5 technology that runs smoothly on mid-range Android devices, while Evolution Gaming's live casino app streams at reduced bitrates on slower connections to prevent buffering. Crash games like Aviator and Spaceman load in under 2 seconds on 4G.

Donbet's mobile platform does not support split-screen multitasking on tablets, and the live casino lobby lacks a picture-in-picture mode. Players who want to watch a live dealer table while browsing slots must switch between tabs, which pauses the live stream. Desktop players get a superior multi-table experience, particularly for live blackjack and roulette.

Does Donbet offer a dedicated mobile app in 2026?

No native app exists for Donbet Casino in 2026. The operator has consistently opted for a progressive web app approach, which offers offline caching for the lobby and faster subsequent loads. This strategy mirrors the approach taken by MrQ Casino and PlayOJO Casino in the UK market, both of which dropped native apps in favour of browser-based platforms between 2023 and 2025.

The absence of an app does not limit game access, as the full library of 4,500+ titles works through mobile browsers. However, players who prefer app-based authentication or fingerprint login will find the browser version less convenient. Donbet's mobile site does support Face ID and fingerprint authentication through the WebAuthn standard on compatible devices.

Donbet Casino Customer Support: Channels, Response Times and Quality

Donbet provides customer support through 24/7 live chat, email at support@donbet.com, and a contact form on the website. Live chat response times average 1 minute 45 seconds, with resolution times for common queries under 5 minutes. Email support responds within 4 hours on average, though complex KYC disputes can take up to 48 hours for a full resolution.

The support team operates in English, German, Finnish and Norwegian, with additional languages available during European business hours. Agents receive training on responsible gambling protocols and can initiate self-exclusion requests directly. Donbet does not offer telephone support, which distinguishes it from UK-licensed operators like Betfred Casino and Coral Casino that maintain phone lines.

How effective is Donbet's complaint resolution process?

Donbet follows a three-tier complaint process: initial support review within 24 hours, escalation to a senior manager within 48 hours, and final resolution within 7 business days. Players who remain unsatisfied can escalate to the Curaçao Gaming Control Board, though this external process typically takes 30 to 60 days and rarely results in player-favourable outcomes.

Independent review platforms show that Donbet resolves approximately 78% of complaints in the player's favour when the player provides clear documentation. The most common complaint categories involve bonus term disputes and KYC documentation rejections. Donbet's willingness to review decisions on appeal compares favourably to many offshore operators, though it still falls short of the IBAS-mediated process available at UK-licensed casinos.

What languages and time zones does Donbet support cover?

Live chat operates around the clock across all time zones, with English-speaking agents always available. German and Finnish support runs from 8am to midnight Central European Time, while Norwegian support operates from 9am to 9pm CET. During peak UK evening hours, average wait times for live chat stay under 30 seconds due to the operator's staffing model.

Email support does not guarantee response times outside European business hours, with queries sent on weekends typically answered by Monday morning. The support team's knowledge base covers common questions about deposits, withdrawals and bonus terms, with articles updated quarterly to reflect policy changes.

Donbet Casino Payment Security and Data Protection

Donbet uses 256-bit SSL encryption across all data transmissions, certified by Comodo. Player funds are held in segregated accounts separate from operational funds, though these accounts sit with payment processors rather than a UK-regulated bank. The casino's privacy policy complies with the General Data Protection Regulation, applicable because N1 Interactive Ltd is registered in Malta.

Donbet does not offer two-factor authentication as a standard feature, though players can request it through customer support. The casino's fraud prevention team monitors transactions for unusual patterns, and accounts showing signs of bonus abuse or multi-accounting face immediate suspension pending investigation. Withdrawal requests to unverified payment methods are automatically rejected.

What happens to player funds if Donbet Casino closes?

Segregated accounts mean player funds remain accessible even if Donbet ceases operations, provided the payment processor holds sufficient reserves. However, the Curaçao regulatory framework does not mandate a player protection fund equivalent to the UK's Financial Services Compensation Scheme. Players with balances at a closed Curaçao casino have no guaranteed route to recovery.

This risk is not merely theoretical. Several Curaçao-licensed casinos have closed since 2020, and players in some cases waited over 12 months for fund recovery through the liquidation process. UK-licensed operators must maintain funds in ring-fenced accounts with quarterly audits, providing a stronger guarantee that balances remain payable.

Does Donbet share player data with third parties?

Donbet shares limited personal data with payment processors, verification services and software providers as necessary to operate the platform. The casino does not sell player data to marketing companies, and its privacy policy prohibits third-party use of personal information for unrelated purposes. Marketing communications require explicit opt-in consent under GDPR.

Players who close their accounts can request full data deletion under GDPR Article 17, with Donbet required to process the request within 30 days. The casino retains transaction records for 5 years to comply with AML regulations, but these records are stored separately from personal data and accessed only by authorised compliance staff.

Donbet Casino: Strengths, Weaknesses and Who Should Play

Donbet's strengths lie in game variety, withdrawal speed and responsive customer support. The 4,500+ game library rivals any UK-licensed operator, and 24-hour withdrawal approvals beat the industry standard. Players who value fast payouts and broad game selection will find Donbet competitive, provided they understand the regulatory trade-offs.

The weaknesses are equally clear: the Curaçao licence offers limited player protection, the euro-based system costs UK players 2% to 3% per transaction, and the absence of GAMSTOP requires manual self-exclusion management. Bonus terms carry restrictive caps, and the 35x wagering requirement sits at the high end of industry norms.

Who should consider playing at Donbet Casino?

Experienced players who understand offshore licensing, manage their own gambling limits, and prioritise game variety over regulatory oversight will find Donbet a solid choice. The casino suits players comfortable with cryptocurrency deposits, those who play slots more than live dealer games, and anyone who values rapid withdrawal processing over the slower but more protected UK-licensed experience.

Players new to online gambling, those who prefer live dealer games, and anyone who wants the safety net of GAMSTOP should choose a UK-licensed operator instead. Bet365 Casino, William Hill Casino and 888 Casino all offer comparable game libraries with the full suite of UKGC protections, at the cost of slower withdrawals and fewer bonus options.

What is the final verdict on Donbet Casino in 2026?

Donbet Casino delivers a competent, feature-rich gambling experience that competes well within the offshore market. The platform's technical performance, game library and support quality all exceed expectations for a Curaçao-licensed operator. The casino is honest about its regulatory status, and its terms are no more restrictive than those of comparable offshore rivals.

UK players should weigh the 2% to 3% currency conversion cost and the lack of GAMSTOP participation before depositing. For players who accept these conditions, Donbet offers a reliable platform with fast payouts and responsive support. For everyone else, the protections of a UKGC-licensed operator justify the slower withdrawal times and smaller game libraries.

Gambling carries significant financial risks, and no bonus structure or game library changes that fundamental reality. If you choose to play at Donbet Casino, set deposit limits before your first deposit, track your play against a monthly budget, and treat the 35x wagering requirement as a cost of entertainment rather than a path to profit.

When gambling stops being fun, the National Gambling Helpline at 0808 8020 133 provides free, confidential support around the clock, and GAMSTOP registration at gamstop.co.uk offers a practical route to a complete break from UK-licensed gambling sites.
