21 Dukes Casino expert review

The online casino has been in the gambling business for over 20 years. Today it has solid reputation of a fair and reliable place, a versatile bonus program and hassle-free payouts with no fees applied. The lobby displays slots from three internationally known providers such as Betsoft, and a live casino lobby features many exciting high-quality tables from Vivo. The mobile version of the casino is as impeccable as the traditional, desktop platform, and offers nearly the same number of video slots including progressive games. Registration is easy and requires a scant amount of personal documents for verification.

The visual design of the casino is pleasant to the eye. With black background and minimalist homepage, the casino has neat and easily readable user interface that makes it simple to surf the website and find everything one needs within mere seconds. The same level of simplicity and high level of functionality is also applicable to the mobile casino. At the top of the homepage there is a carousel of slot titles with the highest winnings on them – this gives players an opportunity to go to the best-paying slots right away. Besides, a Total Jackpot meter shows a constantly changing value of all progressive jackpots accumulated so far, and this cannot but encourage new players to give a spin to some of the best progressive slots in the online casino.

Deposits and withdrawals in 21 Dukes

The casino strives to provide comfortable money transfers, that is why it offers only the most reliable payment methods for depositing funds including VISA, MasterCard, ecoPayz, Neteller, Skrill, EasyEFT and bitcoins. All of the mentioned operators process requests almost instantaneously and the player will see the money on their casino balance within seconds. The deposited amount cannot be less than R100.

For withdrawing, only ecoPayz and bitcoins can be used by SA gamblers. This poses some inconvenience yet the casino offers friendly withdrawals limits: R500 as a minimum per transaction and R40,000 per week. Winnings derived from progressive jackpot winnings are exempt from this limitation. Players of high VIP levels at the casino have the limit increased by casino administration. The funds normally appear on the user’s bank account within 5 days since the cashout request has been submitted.

Slots and other games in 21 Dukes

The slots nomenclature published in the online casino is country-specific, and South African residents can play any game released by Betsoft, Pragmatic Play and Octopus Gaming. The live casino tables are represented by Vivo, one of the best providers of live solutions to online casinos. To facilitate the user search, all games are placed in separate groups including Slots (5-reel games), Classic Slots (3-reel games), Live Casino, Table Games and Video Poker. The Top Games menu contains the most popular slots.

When in game category, the player can refine an extensive list by applying a few filtering options, for example, by provider. In general, nearly every slot supplied by Betsoft and other 21 Dukes vendors has something interesting to offer. Most video slots have impressive second-screen features, wild symbols and free spins. Bet sizes used in video slots will cater for the preferences of low rollers and players with high budgets alike. If the player finds any game deserving their attention, he can click a small star icon attached to that slot and place it into Favorites for further sessions.

Classic slots (those with 3 reels) also have a decent representation in the online casino. The titles like 888 Gold, Triple Tigers, Crazy Pizza and Treasures of Pharaohs have a small number of paylines and an authentic Vegas feel to them. These and other classic titles can be played for real money and for fun credits.

In addition to the above, the casino presents over a dozen table games and exciting live casino games. Table and card games include many blackjack variants, European/American roulette and baccarat. Developed by Vivo Gaming, live tables create full immersion into the real-life casino environment. With HD video streaming, professional croupiers and lots of real people around, the live casino is an excellent addition to the gaming portfolio offered in 21 Dukes.

21 Dukes Mobile Casino

SA gamblers can visit their favorite legal online casino when riding a long way on a bus or queuing thanks to a full-featured mobile casino version that 21 Dukes has developed. Nearly all video slots that desktop users enjoy are also available on mobile, with no quality lowered down. Signing up, logging in, claiming of bonuses, tourneys and other features are implemented perfectly in the mobile casino. Besides, players can deposit and withdraw money when visiting the mobile casino.

21 Dukes customer support

Everything is OK about the online casino. Every aspect deserves high rankings, except for customer support, which lacks a live chat. Registered users or guests can contact casino reps via email only. Some of the most frequent problems (and solutions) are described in a big FAQ section.

Bottom line on 21 Dukes

The online casino is well-established in South Africa. Thousands of SA gamblers feel home in 21 Dukes because the casino provides a high level of comfort and smooth gaming experience all the way through. No issues have been found so far on mobile platforms – the casino operates like clockwork.
