Casino History

White Hat Gaming Limited owned 21 Casino, which launched in 2015. The casino targeted players in the UK and European gambling markets. The review says 21 Casino soon attracted interest from people seeking a more contemporary online gambling experience, and points to the then-new, full-service casino platform from White Hat Gaming Limited as part of its appeal.

White Hat Gaming’s platform lets investors set up online casinos under their own brands and run promotions. The review describes a package that gives operators access to 1,000 games, licensing across multiple jurisdictions, payment processing, risk and fraud protection, customer support, and player-retention services.

The review notes that 21 Casino shared its White Hat Gaming platform with Casilando (2017), Playzee (2018) and Miamai Dice (2016). At the time, the writer predicted that this ambitious platform would keep growing and become a significant force in online casinos over the next decade.

Licences, security and fair play

21 Casino’s owner, White Hat Gaming Limited, held three gambling licences: from the UK Gambling Commission, Malta Gaming Authority and Swedish Gambling Authority. It described the Swedish regulator as new at the time and praised the UKGC and MGA as leading European authorities. These are the review’s claims and historical framing.

The review also cited the UKGC’s 10-steps-to-cyber-security and characterised it as a strong framework for protecting the security and privacy of online services.

It further describes White Hat Gaming’s platform as including a regulatory and legal team. Operators using the platform could draw on that team to seek licences in the jurisdictions they intended to serve. For instance, the review says that an operator targeting the UK could receive help applying for a UKGC license and meeting its rules and regulations.

Based on those points, the original review judged 21 Casino to be a good option for players seeking a site attentive to regulation and fair play. It asserted that White Hat Gaming ensures all its operators/casinos 100% comply with local regulations; that is the guarantee, not an independently verified finding here.

Bonuses and promotions

The review portrays 21 Casino as offering several ways for players to receive promotions. Alongside a welcome offer, it says new account holders received free spins simply for registering, while existing players could find recurring promotions and loyalty rewards intended to add variety to play.

Welcome offer

21 Casino offered a welcome package worth up to €300, plus 21 free spins for opening an account. Those spins were available on the Book of Dead slot without making a cash deposit. The welcome offer was described as a 121% deposit match, capped at €300.

Both offers came with terms and conditions, which the review advised readers to examine. It singled out the 35x wagering requirement: bonus cash and any winnings from the spins had to be wagered 35 times before withdrawal, according to its account of the terms.

The review notes that game categories count differently toward wagering requirements. It sets out the contribution rates as follows:

  • Slots: 100%
  • Table games: 10%
  • Video poker games: 5%
  • Scratchcard & Keno games: 100%
  • Progressive jackpot slots: 0%
  • Other games: 0%

Although the stated contribution for slots was 100%, the review cautions that a number of individual slot titles were excluded from wagering credit. Its advice was to consult the excluded-games list before using bonus funds.

Further bonuses and promotions

The review’s promotions section covers returning customers as well as new players. It says 21 Casino regularly introduced fresh bonuses and offers intended to reward loyal players, in addition to the welcome bonus and no-deposit 21 free spins.

Two offers cited were the Wild Reload Bonus and Stairway Bonus. The first was described as a 21% deposit match up to €210, available on Mondays and Tuesdays each week. The second was a three-tier weekend deposit offer, with 10, 25 and 50 free spins for the 1st, 2nd and 3rd deposits respectively.

Loyalty scheme

The review also outlines a loyalty program at 21 Casino, where players could earn points through wagering. Its stated rate was one point award for every €10 wagered at 21 Casino, with points earned as follows:

  • 2.00 points – For slots or scratchcards
  • 1.00 point – For video poker or bingo
  • 0.50 points – For blackjack
  • 0.25 points – For roulette

According to the review, points could be exchanged for bonus funds at a rate of €1 for every 200 loyalty points. It also says the 35x wagering requirement applied to this bonus cash.

Payment methods

The review describes several ways to move funds into and out of 21 Casino. Direct payment options included bank cards and bank transfers, with e-wallets making up much of the remaining selection.

The currencies listed for deposits and withdrawals at 21 Casino were GBP, EUR, CAD, NOK, SEK, and SAR.

Making a deposit

The original review sets the minimum deposit at 21 Casino at €10 and lists several ways to pay: Visa/Mastercard, Maestro, Bank Transfer, Skrill, Neteller, Trustly and Paysafecard.

The review gave no maximum deposit figure, though it expected the chosen payment service to impose some limit. It said 21 Casino did not charge an additional deposit fee. Deposits were described as generally prompt, except that bank transfers could take a few days.

Withdrawing funds

According to the review, a withdrawal had to use a payment method previously used for a deposit at 21 Casino. It gives a €20 minimum and a maximum of €25,000 per player over a seven day period. The review further states that wins exceeding €100,000 would be distributed in ten monthly installments.

According to the review, 21 Casino charged no withdrawal fees, but processing could be slow. E-wallet withdrawals were said to be completed within a day; credit/debit card payments could take up to 5 business days, while bank transfers were described as taking three days as the norm.

Game selection

The original review counted more than 900 games at 21 Casino and estimated the total was nearer 1,000, while acknowledging it had not checked every title individually. It describes a substantial slot range, a respectable table-game selection, some scratchcards and other formats, and a smaller live dealer section.

In the main lobby, the review says, selecting ‘Games’ opened more categories along the page’s top edge to help filter the titles. Listed categories were ‘Top Games’, ‘New Games’, Slot Games’, ‘Live Casino’, ‘Table Games’, ‘Jackpot Slots’, ‘Other Games’, and ‘Providers’.

Casino Games Software Providers

The review counted 86 software studios represented at 21 Casino. It noted that some names might be unfamiliar, while judging the overall number unusually high compared with other online casinos it had seen.

Among the better-known providers it names are Microgaming, NetEnt, Evolution Gaming, Play’n GO, Thunderkick, Quickspin, Big Time Gaming, Blueprint Gaming, Scientific Games, Red Tiger, Bally and Betsoft.

Slot games

Slots form a major part of many online casino catalogues, and the review says 21 Casino offered players an extensive selection. It points to games from numerous studios and a steady supply of different titles to explore.

The review estimates that at least 900 titles are online slots, spanning different reel styles, themes and bonus features. Its examples include classic games, 3D titles, animated video slots and progressive jackpot slots, all listed as available at 21 Casino.

It also points to familiar titles in the catalogue, including The Goonies, Book of Dead, Starburst, Bonanza, Dead or Alive II, Immortal Romance, Raging Rhino, Game of Thrones, Aloha Cluster Pays and Jurassic Park.

The review counted 36 progressive jackpot slots among the wider catalogue. It says the ‘Jackpot Slots’ category brought together titles such as Mega Fortune, Mega Moolah, Mega Fortune, Slots O’ Gold, Irish Riches and Mega Joker.

Table games

Alongside its slot catalogue, 21 Casino was described as offering 75 table games. The review says they varied in game format, betting limits and quality, giving players a range of table-play options.

Roulette and blackjack made up much of this section, with 16 roulette games and 25 blackjack games reported. Other table options included Baccarat, Red Dog, Pontoon, Pai Gow, Sic Bo, Punto Banco and Oasis Poker.

For roulette, the review lists French, American and Roulette versions with differing rules, plus variations such as Double Ball Roulette, Roulette Advanced and Lightning Roulette.

Blackjack included tables using the familiar rules as well as versions with different features. The named variations were Shut Em Up Blackjack, 6 in 1 Blackjack, Multi-Hand Blackjack, Double Exposure Blackjack and 21+3 Blackjack.

Live casino

The review credits Evolution Gaming as the provider of 21 Casino’s live dealer games, which it says were grouped under the ‘Live Casino’ category at the top of the screen. It counted 16 tables, a selection it considered fair in size, though not extensive.

The review speculates that the smaller table count compared with other casinos may reflect the limited number of blackjack and roulette options. It says there was one table each in Roulette Live and Blackjack live, where other sites might offer several of each.

21 Casino 4

In addition to those, the review lists 14 other games, each with a single table. That range included Sic Bo, Baccarat, Casino Hold’em, Caribbean Stud Poker, Dragon Tiger and Texas Hold’em Bonus.

Mobile casino

The review says 21 Casino was designed to give mobile users an experience comparable to desktop play. Its responsive website adjusted the layout to the screen being used, whether a large monitor, medium-sized tablet or small smartphone, so that the page remained fitted to the display and convenient to navigate.

Desktop users could also download a dedicated app, according to the review. It described the app as offering smoother performance and simpler navigation, with access to as many games as the casino’s website.

Customer support

The review reports that 21 Casino’s customer support was available 24/7 through email and live chat, but not by phone. It characterised staff as responsive and friendly, while noting that the absence of a phone number could frustrate some players.

  • Live chat
  • Email assistance

Playing at 21 Casino

The original review was broadly positive about 21 Casino, with a larger live dealer selection its main suggested improvement. It described a contemporary, mobile-friendly site with a large game catalogue and licences from three major regulators at the time of writing.

It also highlighted the breadth of games and software studios, the bonuses and promotions, and support that it characterised as quick and informative. These assessments reflect the original review and are not a fresh check of the casino.
