What is Diamond 7 all about?

Diamond 7 focuses on providing a well-rounded experience for bettors of all interests. Its vast portfolio of games, refreshed promotions, accessible user interface and rewarding loyalty programme stand out as some of the most enticing features in today’s iGaming scene.

Bonuses

Promotional content is front and centre at Diamond 7. The UK online casino site distributes high-quality bonuses to all registered users - with significant attention placed on the ease at which users can claim each offer. To be specific, Diamond 7 publishes a valuable welcome bonus, weekly Sunday boosts and a Game of the Month event. 

Here’s a quick breakdown of the site’s current welcome offer - a 100% deposit bonus worth up to £100:

  • Deposit £20+ to qualify. 
  • Comes with 100 free spins to use on Hotline or Fruit Spins.
  • Bonus cash must be used within 30 days of activation.

Bonus spins shall be credited to users over the course of five days in denominations of 20 spins per day. These spins may be used on either of the two games mentioned above - but it should be noted that a £50 winning limit applies to this element of the promotion. Moreover, bonus spins expire after 10 days; giving players ample time to work through the deal. 

As for Diamond 7’s Sunday bonus; users can clinch a 30% bonus worth up to £100 upon depositing. Minimum deposits open from £10 - so this offer is slightly more accessible than the aforementioned welcome package. 

Available games

Online casinos are incomplete without an extensive range of elite games provided by top studio developers. Diamond 7 casino delivers on this front by publishing 1,500+ sought-after titles, covering most of the industry’s favourite themes and game genres. For context, you will encounter hit releases like Book of Dead, Big Bass Bonanza and Starburst on the site. Developers include big-name teams such as Microgaming, Inspired Gaming, IGT and Play’n GO.

User experience and interface

User accessibility has never been more important than it is in today’s highly competitive iGaming market. That’s why Diamond 7 stands head and shoulders above many rivals - as the site boasts an easily navigable interface without much clutter. The sole downside is that game pages may occasionally load noticeably slowly. However, Diamond 7’s overall UI aptitude is up there with the best in the business on both mobile and PC platforms. 

Mobile and app compatibility

Not all leading UK online casino platforms need an app to best serve users. Diamond 7 is a shining example of that fact - as the mobile leg of the website houses the same vast collection of games and bonuses for all players. There are no compromises attached to the smartphone and tablet versions, allowing users to revel in all of the first-class casino accoutrements at Diamond 7.

VIP programmes and loyalty rewards

One of Diamond 7’s outstanding attributes is the loyalty programme for consistent casino bettors. Dubbed the ‘Loyalty Points Programme’, the points-based system seeks to reward players who bet on the site’s games. Here’s a breakdown of the points value per £10 bet on each game genre:

  • Roulette - 0.25 points
  • Blackjack - 0.5 points
  • Scratchcards - 2 points
  • Slots - 2 points
  • Video Poker/Video Poker sidebet - 1 point

Newly registered users receive 500 points upon creating an account. Every 1,000 accrued points may be cashed in for £5 in bonus funds.

Diving deeper into Diamond 7

While games and bonuses are vital to Diamond 7’s success as a UK casino site, an assortment of equally important safety-adjacent factors must also be analysed in order to attain a holistic view of the platform. Let’s examine some pertinent features here. 

Licencing

Diamond 7 is licensed by the UK Gambling Commission through its management firm, White Hat Gaming Limited. This certification permits the online casino to serve UK players while adhering to strict gambling rules and regulations. The operator is headquartered in Malta.

Payment methods

Transactions are available via several popular banking options in the UK, such as; Trustly, Mastercard, Visa, Instant Bank Transfer, Revolut, Neteller, Paysafecard, Skrill and Neosurf. PayPal is currently unavailable.

Software providers

Relevant to the unwavering growth experienced by Diamond 7 since its inception in 2015 is the number of strong software providers with whom the site collaborates. Pragmatic Play, Red Tiger Gaming and Hacksaw Gaming form a handful of great studios whose games are listed on Diamond 7 - while niche outfits like Synot Games and Raw iGaming also enter the fold.

Security and fairness

There is no more important component tied to online casino sites than that of security and fairness. Diamond 7 works alongside the UK Gambling Commission and Malta Gaming Authority to uphold white-hat services, while also incorporating SSL encryption to protect user data. 

Responsible gambling measures

Links to helpful safer gambling organisations are sprinkled throughout Diamond 7. Access to BeGambleAware, GamCare and Gambler’s Anonymous are all available – as well as key information on how to stay safe while betting online. Crucially, Diamond 7 offers in-house self-limiting tools designed to protect users from potential gambling harm. 

FIRST rating: 4.3/5 stars

A solid UI offering bolstered by games from well-regarded software teams; Diamond 7 lives up to much of the hype surrounding the site. More could be done to improve blackjack options and a downloadable app would represent a fantastic addition - but the current product is one worth giving a go regardless.
