GQBet Sister Sites: Top Alternative Sites Like GQBet

GQBet names International Features Ltd. as operator but publishes no licensing authority or number. Zero genuine GQBet sister sites are confirmed. This guide profiles five likely platform-linked sites while separating shared technology from legal ownership.

Comparison of Sites Like GQBet Casino

Searches for GQBet sister sites produce several visually convincing candidates, yet all five profiles below name RegalTech Solutions Limitada rather than International Features Ltd. They share GQBet’s distinctive /en-UN route, footer layout and much of its game mix. Those are useful platform fingerprints, not proof of common ownership.

The five brands are likely platform-linked sites, not confirmed legal sisters; bonus availability and currency depend on the player’s market.

The same legal-entity rule used when comparing Harrys sister sites or reading a Velobet network guide matters especially here. GQBet publishes no regulator or licence number, whereas every profiled brand claims the same Tobique reference under a different company. The phrase GQBet casino sister casinos therefore describes a search category, not an established corporate family, as the Harrys Casino review also demonstrates.

QBet: the closest name but a different operator

QBet launched in 2022 and is the most obvious candidate among sites like GQBet because of its name, product layout and shared /en-UN route. It offers casino games, live tables and sports betting through a dark, promotion-led interface. That resemblance is strong enough to support a likely platform connection, but QBet’s current legal statement names RegalTech Solutions Limitada. GQBet instead names International Features Ltd., so searches for QBet sister sites should not be treated as proof that the two brands share an owner.

The catalogue contains more than 4,000 titles. Named suppliers include Play’n GO, Evolution, Pragmatic Play, Quickspin, Yggdrasil, Hacksaw Gaming, NetEnt and BGaming. That selection overlaps heavily with GQBet’s lobby, although shared studios are common across online casinos and do not settle ownership. QBet’s library is smaller than GQBet’s current catalogue estimate of approximately 7,200 titles, making GQBet the broader choice on raw count.

QBet’s welcome promotion is a 100% match up to €100 plus 100 free spins. The bonus carries 35x wagering and a 30-day deadline. One current bonus record gives a €10 qualifying deposit, while another distinguishes the €10 cashier minimum from a €20 activation threshold. Players should therefore read the displayed terms before depositing rather than assuming the lower figure unlocks the offer. No separately evidenced points-based loyalty club changes that calculation.

Banking options include Visa, Mastercard, Sofort, bank transfer, CASHlib, AstroPay Card, Jeton, MiFinity, eZeeWallet, Flexepin and cryptocurrencies. The operator says up to 80% of withdrawals are instant, with other requests taking as long as three working days depending on method. Successful users have described fast payouts, but verification delays and disputed bonuses also appear in reports. QBet’s closer naming and stronger recorded player score make it the leading platform-linked pick, while its different operator and modest bonus ceiling are the decisive drawbacks, with what the Velobet review found supplying a separate operator benchmark.

55BET: broader catalogue with operator-history caveats

Launched in 2024, 55BET combines slots, live casino and sportsbook products in the same type of interface used by GQBet. Its /en-UN route and footer structure support a likely technical relationship. The legal evidence does not establish a GQBet sister site, however: 55BET names RegalTech Solutions Limitada and claims Tobique Gaming Commission licence 0000087, while GQBet names International Features Ltd. without supplying a regulator or number. Lists of 55BET sister sites that merge the brands solely because they look alike overstate the evidence.

55BET has the largest stated catalogue in this five-brand set, with more than 5,000 titles. Providers include Play’n GO, Yggdrasil, Evolution, Hacksaw Gaming, Novomatic, Pragmatic Play and NetEnt. Live casino is available, and the sportsbook makes it a closer product match to GQBet than a slots-only brand would be. GQBet nevertheless retains the higher current game estimate.

The standard welcome bonus is 100% up to €100 with 35x wagering. The displayed regional version uses an equivalent NOK 1,000 ceiling and requires at least €10 or NOK 100, depending on currency. This is a simpler one-deposit proposition than the staged offers at SlotExpress and Manga Casino, but its €100 maximum is much lower than GQBet’s £500 or €500 headline. No independently documented loyalty ladder adds continuing value after the welcome offer.

Payment methods include Visa, Mastercard, Sofort, bank transfer, CASHlib, AstroPay Card, Jeton, cryptocurrencies, MiFinity, eZeeWallet and Flexepin. The operator describes up to 80% of withdrawals as instant and allows up to three working days for others. Positive reports mention fast payments, smooth verification and usable game navigation. The larger 35-review sample produces a 2.6/5 rating, with complaints about delayed withdrawals, account restrictions, marketing messages and support. Its catalogue is the clear advantage; its player record and the historical change in the company named on the domain require more caution.

30Bet: the largest single-deposit match

30Bet launched in 2023 with casino, live-dealer and sports products. It uses the same distinctive platform cues as GQBet, including a matching locale structure, but its legal statement names RegalTech Solutions Limitada. There is no document placing RegalTech and International Features Ltd. under one parent or licence account. Consequently, 30Bet sister sites searches may reveal a platform cluster, but they do not establish that 30Bet is one of the sister sites of GQBet.

The game lobby contains approximately 4,000 or more titles from NetEnt, Play’n GO, Evolution, BGaming, Habanero, Pragmatic Play and Yggdrasil. Live casino is included, while the connected sportsbook gives players a product range broadly comparable with GQBet. The estimated catalogue is substantial but remains below GQBet’s current count.

30Bet has the strongest single-deposit headline among the five profiles: a 100% match up to €500 plus 50 free spins. The minimum qualifying deposit is €20, wagering is 35x the bonus and the recorded promotion is presented as a first-deposit offer. Its general cashier minimum is lower at €10, which should not be confused with the amount required to activate the bonus. The supplied promotion evidence does not establish a separate points or cashback loyalty programme.

Banking methods include Visa, Mastercard, Sofort, bank transfer, CASHlib, AstroPay Card, Jeton, cryptocurrencies, MiFinity, eZeeWallet and Flexepin. As with several brands on the RegalTech platform, the operator says up to 80% of withdrawals are instant and that other methods may take three working days. Reports include successful fast verification and payments, but also delayed deposits or withdrawals, restricted accounts, marketing complaints and disputed balances. The 2.7/5 rating comes from 213 reviews, the largest sentiment sample in this comparison. The €500 match is its standout feature; the low rating and recurring cashier disputes are its principal weaknesses.

SlotExpress: the richest three-deposit welcome package

SlotExpress launched in 2024 with a slot-focused identity, although its lobby also includes live tables. The site uses the shared /en-UN platform pattern and names RegalTech Solutions Limitada under operator-stated Tobique licence 0000087. GQBet’s footer names a different company and no licensing authority, so the technical resemblance supports likely status only. SlotExpress sister sites pages that describe common ownership without addressing that legal difference go beyond the available evidence.

Current catalogue estimates range from roughly 3,000 to more than 4,000 games, depending on market and counting date. Pragmatic Play, Play’n GO, Evolution, Hacksaw Gaming, NetEnt, Yggdrasil and BGaming are among the leading suppliers. That provides ample slot and live-casino variety, but both the lower and upper estimates trail GQBet’s catalogue count.

The welcome package offers up to €1,000 plus 200 free spins across three deposits. Stage one is a 100% match with 100 spins, stage two is a 50% match with 50 spins, and stage three is a 25% match with another 50 spins. Each stage requires at least €20. Wagering is 40x the deposit plus bonus, which is materially heavier than a 35x bonus-only condition because the original qualifying deposit is included in the turnover calculation. No separate loyalty programme is needed to explain the main value proposition: it is concentrated in this staged package.

Available banking can include cards, Neteller, Skrill, Paysafecard, Zimpler, bank transfer, Apple Pay, Google Pay, BLIK, MiFinity, Rapid Transfer, Flexepin, CASHlib, Jeton, Revolut and several cryptocurrencies. Methods vary by market and account currency. The operator describes most withdrawals as instant and allows up to three working days for others. Positive reports mention fast payouts and the game range; negative reports focus on withdrawal delays, identity or bank-document disputes and support responsiveness. The large headline is attractive, but the 40x deposit-plus-bonus formula is the most demanding wagering term in the comparison.

Manga Casino: a two-stage offer with live depth

Manga Casino is generally dated to 2023, although some secondary records state 2022. It uses a colourful illustrated theme across casino and live-casino sections. The site’s legal statement names RegalTech Solutions Limitada, Costa Rica registration 3-102-924841, operator-stated Tobique licence 0000087 and Petillant Solutions Ltd., Cyprus HE 476155, as payment agent. GQBet names none of those entities. The common platform structure therefore supports a likely link, but Manga Casino sister sites should not be described as part of a confirmed GQBet corporate network.

The catalogue contains approximately 4,100 titles, including roughly 3,778 slots in one current count. Suppliers include Pragmatic Play, Play’n GO, Relax Gaming, Hacksaw Gaming, Nolimit City, NetEnt, Big Time Gaming, Yggdrasil, Quickspin, BGaming and Red Tiger. Live tables are available, and the combination of branded visuals, slots and live dealers gives Manga Casino a clearer casino identity than the sportsbook-led parts of GQBet.

Its welcome package provides up to €300 plus 50 free spins across two deposits. The first stage is a 100% match up to €100 plus 50 spins, followed by a 50% match up to €200. The minimum qualifying deposit is €10, the deadline is 30 days, and both bonus funds and free-spin winnings carry 35x wagering. No verified points-based loyalty ladder forms part of the recorded package.

Banking methods include Visa, Mastercard, Sofort, bank transfer, Google Pay, CASHlib, AstroPay Card, Jeton, cryptocurrencies, MiFinity, eZeeWallet and Flexepin. The operator says up to 80% of withdrawals are instant, with method-dependent processing of up to three working days for the remainder. Positive reports mention the design, live games and some fast payouts. Other players describe missing deposits, bonus-credit disputes, verification delays and slow support. Its two-stage bonus is easier to complete than SlotExpress’s three-deposit package, but the larger sentiment sample rates Manga Casino at only 2.3/5, while how Cosmobet compared provides a non-sister benchmark.

How We Tested These Sister Sites

This comparison uses a same-licence test: GQBet’s legal statement names International Features Ltd. without identifying a regulator, whereas all five candidates name RegalTech Solutions Limitada and claim Tobique licence 0000087. The official holder list confirms RegalTech as a B2C holder until 17 July 2027, but does not display that licence number or enumerate the five domains. Their shared /en-UN route therefore counts only as platform evidence, leaving every profile in the likely tier. Commercial comparisons use recorded bonuses, minimum deposits, payment methods and operator-stated payout windows. Ratings retain their review counts, and withdrawal estimates of instant service or up to three working days are not treated as measured cash-arrival times. This remains an editorial comparison, not a funded account test; Bingo All Stars supplies the full operator assessment as a separate benchmark.

Bonus and Wagering Requirements at Sites Like GQBet

GQBet’s hero promotes a welcome bonus of up to €500 or £500. Current secondary details describe a 100% match plus 100 free spins, a €10 or £10 deposit, 35x wagering and a 30-day completion period. The headline is verified directly; the other terms come from a supporting promotion record.

QBet offers 100% up to €100 plus 100 free spins with 35x wagering and a 30-day deadline. Its qualifying threshold differs between a €10 bonus record and a current review separating the €10 cashier minimum from the €20 promotion minimum. 55BET’s casino terms specify 100% up to €100 at 35x from €10. Its homepage separately offers a live-casino bonus of 100% up to €300, a different product from the €100 casino offer; check the product and opt-in terms before depositing, while Freshbet provides another bonus benchmark—read more here.

30Bet’s welcome terms offer 100% up to €500 plus 50 free spins, require a €20 qualifying deposit and apply 35x to the bonus. Its €10 cashier minimum does not activate the package. The homepage says “Claim your EUR 300 now”, below the €500 terms ceiling. Because both figures are first-party, the offer and amount on the deposit opt-in screen govern.

Manga Casino splits up to €300 and 50 spins across two deposits: 100% up to €100 plus 50 spins, then 50% up to €200. Each stage starts at €10; bonus and free-spin winnings carry 35x wagering and a 30-day deadline. SlotExpress spreads up to €1,000 and 200 spins across three deposits of at least €20: 100% plus 100 spins, 50% plus 50 spins, then 25% plus 50 spins. Its 40x applies to the deposit plus bonus, creating more turnover than 35x on bonus funds alone.

Headline-only comparisons with Glossy Bingo promotions or Jettbet bonus terms omit the qualifying deposit, wagering base, deadline and stages. None of these five recorded welcome packages is a no-deposit promotion; the Seven Casino review and comparison applies the same checks to an unrelated alternative.

GQBet vs Its Sister Sites

All five are likely platform links, not confirmed sisters: GQBet names International Features Ltd.; QBet, 55BET, 30Bet, SlotExpress and Manga Casino name RegalTech Solutions Limitada, with no record of common ownership or regulator account.

GQBet leads with approximately 7,200 games and a £500 or €500 headline, plus Sports, Live Betting, Casino and Live Casino. 55BET lists more than 5,000 games, Manga Casino approximately 4,100, QBet and 30Bet about 4,000 or more, and SlotExpress roughly 3,000 to 4,000 or more.

QBet, 55BET, 30Bet and Manga Casino have €10 general minimums; SlotExpress has a €10 general minimum but requires €20 at each welcome stage. Recurring methods are Visa, Mastercard, bank transfer, CASHlib, Jeton, cryptocurrency and MiFinity. All five estimate that up to 80% of withdrawals are instant, with others taking up to three working days by method; these are not verified arrival times. Mr Play offers the evidence-led review as an unrelated alternative.

All five claim Tobique licence 0000087. The official list confirms RegalTech as a B2C holder until 17 July 2027 but links neither that number nor the domains. A Swedish prohibition dated 11 March 2026 named Novatech Solutions N.V. across all five domains; their statements now name RegalTech. The Dutch €24.846 million penalty concerned Novatech, qbet.com and 55bet.com, not GQBet.

With no UK Gambling Commission licence or named external regulator, GQBet players depend on saved transaction records, written correspondence and International Features Ltd.’s internal resolution process.

Payment Methods Comparison

Payout estimates begin after approval and vary by method, verification status, currency and banking network; reported experiences do not guarantee a future result, while the Mr Spin comparison and review provides an unrelated benchmark.

Game Providers Across the Profiled Sites

QBet exceeds 4,000 titles, with Quickspin, Yggdrasil and BGaming beyond the tabled providers. 55BET’s 5,000-plus library is the largest recorded here; Novomatic and NetEnt supplement Play’n GO, Yggdrasil, Evolution, Hacksaw Gaming and Pragmatic Play. Both include live casino content and list Evolution.

30Bet’s approximately 4,000-plus games also include Habanero and Yggdrasil. SlotExpress counts range from approximately 3,000 to more than 4,000 by market and counting date; Yggdrasil and BGaming join its tabled suppliers. Both record live casino games.

Manga Casino has approximately 4,100 titles, including roughly 3,778 slots in one current inventory, the most precise secondary count here. Its suppliers include Pragmatic Play, Play’n GO, Relax Gaming, Hacksaw Gaming, Nolimit City, NetEnt, Big Time Gaming, Yggdrasil, Quickspin, BGaming and Red Tiger.

Play’n GO and Pragmatic Play appear in every recorded catalogue. Evolution appears at QBet, 55BET, 30Bet and SlotExpress; Hacksaw Gaming at QBet, 55BET, SlotExpress and Manga Casino; and NetEnt at every candidate, including Manga Casino’s fuller record despite its abbreviated table entry. Every brand records live casino availability.

Counts vary by market, duplicate treatment and catalogue date, so totals are estimates. Provider overlap establishes shared commercial supply or technology, not shared ownership, and none of these studio lists moves a brand beyond the likely tier.

Safety, Licensing and Regulation

GQBet states that it has passed regulatory compliance and is legally authorised, but the statement identifies neither an authority nor a licence number. Its domain does not appear in the Anjouan domain register, no International Features Ltd casinos appear in the Curaçao OGL licensee register, and GQBet has no UK Gambling Commission licence. The general assertion therefore cannot be matched to a public licence record, which is why International Features Ltd sister sites cannot be established from a register the way a licensed estate can.

Marketing pages carrying GQBet branding describe a Belize e-gaming licence held by International Features Ltd. One names the operator as GQbet Limited and prints the licence number as the unedited placeholder “[BELIZE-GAMING-LIC-2025-XXXXX]”, so no number is disclosed there either. Belize does license online gambling, through the Gaming Control Board under the Gaming Control Act, so this is a real instrument rather than a company registration. What matters is how few exist. The board’s January 2010 notice named two licensed companies, Fulton Data Processing Limited and Sports Off Shore Limited. Its February 2022 notice, issued through the Government press office, said only Mum Casino Ltd held one and told every other entity claiming a Belize licence to cease and desist. Neither names International Features Ltd or GQbet Limited. A player is therefore left with a licence described in marketing, no number published to check it against, and a regulator that has twice warned about unverified Belize claims.

The public Tobique holder table confirms RegalTech Solutions Limitada as a B2C licence holder with an expiry date of 17 July 2027. It does not display licence 0000087 or enumerate the five domains, so the domain-to-licence claim still depends on each brand’s statement.

There is also material operator history on several profiled domains. A Dutch regulator’s decision dated 16 December 2025 and published on 10 March 2026 imposed a €24.846 million penalty on Novatech Solutions N.V., naming qbet.com and 55bet.com. A Swedish decision dated 11 March 2026 prohibited Novatech and named those domains alongside 30bet.com, slotexpress.com and mangacasino.com. By August 2026, the same five domains named RegalTech Solutions Limitada. This is evidence of a company-name change on those domains, not evidence that GQBet belonged to either company. GQBet was not named in either action.

Without a UK licence, players do not have the UK regulatory complaints route or an associated UK alternative-dispute channel. Set account limits before play, preserve copies of terms and transaction records, and confirm which external adjudicator—if any—the operator recognises. A shared account interface does not prove that responsible-gambling controls or complaint handling are administered by the same legal entity; GamCare counselling resources remain available independently.

Common Complaints and Issues

Positive reports across the five profiles mention broad game selection, straightforward navigation and successful fast withdrawals. Those experiences align with catalogues ranging from approximately 3,000 to more than 5,000 titles and with operator claims that up to 80% of withdrawals are instant. Negative reports repeatedly concern delayed or uncredited deposits, verification friction, pending withdrawals, restricted accounts, disputed bonuses or winnings, unwanted marketing and slow or vague support replies.

GQBet has a 2.2/5 rating from 23 reviews. Some users report successful payments, enjoyable games and earlier periods without difficulty. Others describe missing deposits, withdrawal and identity-check friction, bonus disputes and weak support explanations. The 23-review sample identifies recurring themes but cannot establish that every account receives the same treatment.

The likely links contain more specific complaint records. QBet had seven recorded complaints, four marked resolved, alongside its 5.9/10 rating from eight reviews. 55BET had one unresolved complaint in a six-review sample, while another sample rated it 2.6/5 from 35 reviews. A separate 30Bet record contained zero player reviews and two unresolved complaints, while its larger rating was 2.7/5 from 213 reviews. SlotExpress had a second record with two player reviews and two complaints, one unresolved and one rejected. Manga Casino had one unresolved complaint in its four-review record and a separate 2.3/5 score from 53 reviews.

Cashier disputes should be read against each operator’s stated thresholds, set out in the payments table above. Before claiming a bonus, retain the displayed terms and confirmation; before withdrawing, ensure the registered name, address, payment instrument and source-of-funds documents are consistent.

What Users Say About the Profiled Sites

Ratings were captured with review counts in August 2026; differing scales and samples prevent direct numerical ranking. QBet also has seven recorded complaints, four resolved.

55BET, launched in 2024, has a separate 5.7/10 record from six reviews with one unresolved complaint; it records more than 5,000 games.

30Bet’s table score covers the largest sample. Another current record has no player rating and zero player reviews but two unresolved complaints. Its recorded launch year is 2023.

SlotExpress, launched in 2024, has another record with two player reviews and two complaints: one unresolved and one rejected.

Manga Casino has a separate 4.3/10 score from four reviews and one unresolved complaint. Its principal recorded launch year is 2023, although some secondary records state 2022.

Best GQBet Sister Site

Among the best GQBet sister sites in the evidenced platform-linked group, QBet leads, with an important qualification: it remains a likely technical link, not a confirmed legal sister. Launched in 2022, it offers more than 4,000 games from studios including Play’n GO, Evolution, Pragmatic Play, Quickspin, Yggdrasil, Hacksaw Gaming, NetEnt and BGaming. Its 5.9/10 rating is the strongest recorded score in this set, but it rests on only eight reviews and accompanies seven complaints, four marked resolved.

QBet’s welcome package is 100% up to €100 plus 100 free spins at 35x, with a 30-day deadline. Records differ on whether activation requires €10 or €20, although the general cashier minimum is €10. Its payment list includes Visa, Mastercard, Sofort, bank transfer, CASHlib, AstroPay Card, Jeton, cryptocurrency, MiFinity, eZeeWallet and Flexepin. The operator says up to 80% of withdrawals are instant and other methods may take up to three working days.

Cosmobet remains the best non-sister alternative from the separate affiliate roster when the priority is operator diversification rather than another /en-UN platform match. It must be assessed through its own current licence, cashier and bonus terms, and its inclusion provides no ownership evidence about GQBet.

Bonus-led players may instead examine 30Bet’s terms offer of 100% up to €500 plus 50 spins, with a €20 qualifying deposit and 35x wagering. Its homepage headline advertises the smaller figure “Claim your EUR 300 now”, so the amount shown on the deposit opt-in screen governs. SlotExpress advertises the largest total at €1,000 plus 200 spins, but divides it across three €20 deposits and applies 40x to the deposit plus bonus. For catalogue size, 55BET leads the profiled candidates with more than 5,000 games.

How to Spot a Genuine GQBet Sister Site

The operator name is the deciding evidence. Open a candidate’s terms or about page and locate the registered company that enters into the gambling contract. A footer may use a marketing or payment entity while the terms name the contractual operator; if they conflict, the terms carry more weight. GQBet’s /en-UN footer names International Features Ltd., at 284 Barrack Road, Belize City.

Next, match the licence account number rather than the branding. A genuine GQBet sister site should connect International Features Ltd. and the candidate to the same regulator account or identify a documented common parent. Here, the candidates name RegalTech Solutions Limitada and claim Tobique licence 0000087. GQBet supplies neither that company nor that reference, so no candidate meets the same-licence test.

Legal-page fingerprints remain useful for discovery, and here they are unusually precise. GQBet and all five candidates serve their contract pages from the same routes, /en-UN/terms-and-conditions and /en-UN/privacy-policy, behind matching footer furniture and support-page structures. Trying that exact path on a new candidate domain is the quickest way to place it on this platform. It remains a lead to investigate rather than proof of ownership, because the company named inside those pages is what settles the question.

A shared game library, payment providers, visual design, affiliate-directory grouping or identical promotion layout is not ownership evidence. Many sister-site lists treat those clues as proof, which is why their rosters become unreliable. The same caution applies to GQBet sister companies claims.

A Belize claim can also be tested. The Gaming Control Board licenses online gambling under the Gaming Control Act, and it has twice published notices naming the very small number of licensed companies and warning that other claimants should stop. If a candidate cites a Belize licence, look for the licence number and check the named company against those notices. Finally, nobody can prove a complete list of International Features Ltd. casinos from a plain company registration. No regulator currently enumerates domains for that company, while the Tobique holder table does not list domains under 0000087. This is an evidenced roster, not a complete list, and any claim to list all International Features Ltd. sister sites should be treated accordingly.

Final Verdict on GQBet Similar Sites

None of these GQBet alternatives has a British licence, so anyone searching GQBet casino UK should treat that as settled, and a full GQBet review would reach the same conclusion from the operator statement alone. They name RegalTech Solutions Limitada and claim Tobique licence 0000087; GQBet names International Features Ltd. without a regulator or licence identifier. The official list confirms RegalTech as a B2C holder until 17 July 2027 but shows neither 0000087 nor these domains. The verdict is zero genuine sisters and five likely links; the Cocoa Casino review against alternatives remains outside the cluster.

QBet is strongest within the cluster, with more than 4,000 games and a 5.9/10 rating from eight reviews; seven complaints were recorded and four resolved. 30Bet offers 100% up to €500 plus 50 spins on a €20 minimum with 35x wagering. Its homepage says €300, so the deposit opt-in screen governs. SlotExpress’s three-stage package totals €1,000 plus 200 spins, with a €20 minimum per stage and 40x wagering on the deposit plus bonus.

Do not transfer historical records to GQBet: the Dutch €24.846 million penalty named Novatech Solutions N.V. and concerned qbet.com and 55bet.com; the Swedish prohibition dated 11 March 2026 covered Novatech’s use of all five domains. GQBet was named in neither. Preserve the displayed offer, verify the company and licence claim, and complete identity checks before withdrawal; the review of Kinghills Casino is an unrelated benchmark.
