Casino History
White Hat Gaming Limited owned 21 Casino, which debuted in 2015. It was aimed at players in the UK and European gambling markets. The review describes 21 Casino as quickly drawing interest from players looking for a more modern online gambling experience, with White Hat Gaming Limited’s then-new, full-service casino platform cited as one element of its appeal.
White Hat Gaming’s platform allows investors to launch online casinos under their own brands and run promotions. The review describes a package that gives operators access to 1,000 games, licensing in multiple jurisdictions, payment processing, risk and fraud protection, customer service, and player-retention services.
The review says 21 Casino used the same White Hat Gaming platform as Casilando (2017), Playzee (2018) and Miamai Dice (2016). At the time, the writer predicted that the ambitious platform would continue expanding and become a major force in online casinos over the following decade.
Licences, security and fair play
21 Casino’s owner, White Hat Gaming Limited, held three gambling licences, issued by the UK Gambling Commission, Malta Gaming Authority and Swedish Gambling Authority. The review called the Swedish regulator new at the time and described the UKGC and MGA as leading European authorities. This reflects the review’s claims and historical context.
The review also referred to the UKGC’s 10-steps-to-cyber-security, calling it a robust framework for protecting the security and privacy of online services.
It further says White Hat Gaming’s platform included a regulatory and legal team. Operators on the platform could work with this team to seek licences in the jurisdictions they planned to serve. For example, an operator targeting the UK could receive help applying for a UKGC license and complying with its rules and regulations.
Based on these points, the original review considered 21 Casino a good choice for players looking for a site attentive to regulation and fair play. It claimed White Hat Gaming ensures that all its operators/casinos 100% comply with local regulations; this is the company’s stated guarantee, not an independently verified finding here.
Bonuses and promotions
The review describes several promotional options at 21 Casino. It says new account holders received free spins just for registering, while existing players could access recurring offers and loyalty rewards, in addition to the welcome promotion.
Welcome offer
21 Casino offered a welcome package worth up to €300, along with 21 free spins for opening an account. The spins could be used on the Book of Dead slot without a cash deposit. The welcome offer was described as a 121% deposit match, capped at €300.
Both offers had terms and conditions, which the review recommended reading carefully. It highlighted the 35x wagering requirement: according to the review’s account of the terms, bonus cash and all spin winnings had to be wagered 35 times before withdrawal.
The review notes that different game categories contribute at different rates toward wagering requirements. It lists the following contribution percentages:
- Slots: 100%
- Table games: 10%
- Video poker games: 5%
- Scratchcard & Keno games: 100%
- Progressive jackpot slots: 0%
- Other games: 0%
Although slots were listed as contributing 100%, the review warns that some individual slot titles did not count toward wagering. It recommends checking the excluded-games list before playing with bonus funds.

More bonuses and promotions
The promotions section also covers returning players. In addition to the welcome bonus and 21 no-deposit free spins, the review says 21 Casino regularly added new bonuses and offers to reward loyal customers.
Two offers mentioned were the Wild Reload Bonus and Stairway Bonus. The first was a 21% deposit match of up to €210, offered every Monday and Tuesday. The second was a three-step weekend deposit promotion, awarding 10, 25 and 50 free spins for the 1st, 2nd and 3rd deposits, respectively.
Loyalty scheme
The review describes a loyalty program at 21 Casino that awarded points for wagering. Players received one point for every €10 wagered at 21 Casino, according to the stated rate. The point structure was:
- 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
The review says loyalty points could be redeemed for bonus funds at a rate of €1 per 200 points. It also states that the 35x wagering requirement applied to these bonus funds.
Payment methods
The review lists several ways to deposit to and withdraw from 21 Casino. Direct options included bank cards and bank transfers, while e-wallets made up much of the rest of the selection.
Currencies listed for deposits and withdrawals at 21 Casino were GBP, EUR, CAD, NOK, SEK, and SAR.
Depositing
The original review sets 21 Casino’s minimum deposit at €10 and lists Visa/Mastercard, Maestro, Bank Transfer, Skrill, Neteller, Trustly and Paysafecard as payment options.
The review does not specify a maximum deposit, but expects the selected payment provider to impose a limit. It says 21 Casino charged no extra deposit fees. Deposits were generally described as prompt, though bank transfers could take a few days.
Withdrawing funds
The review says withdrawals had to be made using a payment method previously used for a deposit at 21 Casino. It lists a €20 minimum and a maximum of €25,000 per player over a seven day period. It also states that winnings above €100,000 would be paid in ten monthly installments.
According to the review, 21 Casino did not charge withdrawal fees, though processing could be slow. E-wallet withdrawals were reportedly completed within a day; credit/debit card payments could take up to 5 business days, and bank transfers typically took three days.
Game selection
The original review counted more than 900 games at 21 Casino and estimated the total was closer to 1,000, while noting that it had not individually checked every title. It describes a large slot collection, a solid selection of table games, some scratchcards and other formats, plus a smaller live dealer section.
The review says selecting ‘Games’ in the main lobby opened additional categories along the top of the page to help filter titles. Categories listed were ‘Top Games’, ‘New Games’, Slot Games’, ‘Live Casino’, ‘Table Games’, ‘Jackpot Slots’, ‘Other Games’, and ‘Providers’.

Casino game software providers
The review counted 86 software studios at 21 Casino. It notes that some providers may be unfamiliar, but considers the total unusually high compared with other online casinos it had encountered.
Better-known providers named include Microgaming, NetEnt, Evolution Gaming, Play’n GO, Thunderkick, Quickspin, Big Time Gaming, Blueprint Gaming, Scientific Games, Red Tiger, Bally and Betsoft.
Slot games
Slots are a major feature of many online casino catalogues, and the review says 21 Casino had an extensive range. It highlights games from numerous studios, offering players a steady stream of titles to try.
The review estimates that at least 900 titles are online slots, with varied reels, themes and bonus features. Examples include classic games, 3D titles, animated video slots and progressive jackpot slots, all reported as available at 21 Casino.
The catalogue also included familiar titles such as 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 in the broader collection. It says the ‘Jackpot Slots’ category featured games such as Mega Fortune, Mega Moolah, Mega Fortune, Slots O’ Gold, Irish Riches and Mega Joker.
Table games
Alongside the slots, 21 Casino reportedly offered 75 table games. The review says these varied in format, betting limits and quality, giving players several ways to enjoy table games.
Roulette and blackjack accounted for much of the selection, with 16 roulette games and 25 blackjack games reported. Other table games included Baccarat, Red Dog, Pontoon, Pai Gow, Sic Bo, Punto Banco and Oasis Poker.
The review lists French, American and Roulette versions with different rules, as well as variations such as Double Ball Roulette, Roulette Advanced and Lightning Roulette.
Blackjack options included tables with familiar rules and versions with added features. Named variants were Shut Em Up Blackjack, 6 in 1 Blackjack, Multi-Hand Blackjack, Double Exposure Blackjack and 21+3 Blackjack.
Live casino
The review identifies Evolution Gaming as the provider of 21 Casino’s live dealer games, grouped under the ‘Live Casino’ category at the top of the screen. It counted 16 tables, describing the selection as reasonable in size but not extensive.
The review suggests that the lower table count compared with other casinos might reflect a limited number of blackjack and roulette options. It reports one table each for Roulette Live and Blackjack live, whereas other sites might offer several of each.

The review also lists 14 other games, each with one table. These 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 built to provide mobile users with an experience comparable to desktop play. Its responsive site adjusted to the screen, whether a large monitor, medium-sized tablet or small smartphone, keeping the page suited to the display and easy to navigate.
Desktop users could also download a dedicated app, according to the review. It says the app offered smoother performance and simpler navigation, with access to as many games as the casino website.
Customer support
The review reports that 21 Casino’s customer support was available 24/7 via email and live chat, but not by phone. It describes staff as friendly and responsive, while noting the lack of telephone support could frustrate some players.
- Live chat
- Email support
Playing at 21 Casino
The original review gives 21 Casino a generally positive assessment, with a larger live dealer selection suggested as its main area for improvement. It describes a modern, mobile-friendly site with a large game collection and licences from three major regulators at the time of writing.
The review also praises the range of games and software studios, its bonuses and promotions, and support it characterizes as quick and informative. These views are from the original review, not a new assessment of the casino.
