  • Lucrative VIP tournaments
  • Accepts Bitcoin as a payment method
  • Games from multiple vendors
  • Excellent 24/7 live support system
  • 200% Welcome bonus + 25 spins

Overview

This brand is a part of Engage Entertainment Group Inc., a company with headquarters in Antigua and Barbuda. The online casino, therefore, operates beneath a license issued by the Government of Curacao. Although Black Diamond was launched back in 2009, its parent company has thrived for the last 17 years. The service is available globally.

Online security includes Norton, McAfee, SSL, and Security Standards Council, which renders it among the most secure online casinos in the industry. Australian players who need support can reach Gambling Help Online on 1800 858 858 at any hour. Registered Australian wagering accounts can also be blocked in one step through BetStop, the national self-exclusion register.

Other Bonuses and Promotions

To begin with, players can grab a bonus of 200% on their first deposit amounts. Once they have exhausted their first depositors' bonus, they can claim bonuses on their next four deposits. As if this were not enough, players who make bitcoin deposits will be pampered with a bonus of 400%.

Here is a brief overview of all the promotions at Black Diamond Casino:

  • Claim a bonus of 150% on Monday deposits of up to 200.
  • Win 21,000 in blackjack promotions.
  • Win your share of the "200k Guaranteed" and "15k Guaranteed" tournaments.
  • Wager real money on featured slots and win amazing prizes.
  • Get bonuses daily at Black Diamond Casino.

Game Selection

Black Diamond is an instant play casino that offers games from multiple providers. To play for fun or real money, players do not have to download and install any casino gaming software.

Pragmatic Play - This is the former name of Top Game, which is known for its fast downloads and excellent 3D graphics. Play exciting slots such as Dragon Kingdom, 3 Genie Wishes, Wolf Gold, Beowulf, and Hot Safari.

BetSoft - BetSoft Gaming is a specialist in developing 3D slots such as Mr. Vegas, Charms and Clovers, and Greedy Goblins.

Octopus Gaming - A little known provider of high quality slots, Octopus Gaming has released titles such as Three Times the Riches, Trolling for Treasure, and Ducks N Eggs.

Visionary iGaming - ViG develops live dealer games such as American Roulette, Super 6, Live Baccarat, and Live Roulette.

The portfolio at Black Diamond Casino includes over 200 slots such as Mighty Kong, Event Horizon, 2 Million B.C., Slots Angels, Mega Glam Life, Hockey League, and others. There are also over thirty classic slots such as Diamond Progressive, Irish Charms, and Treasures of the Pharaoh 3 Line. The Black Diamond portfolio also includes live dealer games from ViG, table games, video pokers, and other games.

Deposit and Withdrawal Methods

Black Diamond offers several safe and secure banking methods such as Visa, PaySafeCard, MasterCard, Neteller, Skrill, EcoPayz, and Bitcoin. Players can deposit a minimum of 25 at a time, but the withdrawal limits vary according to the VIP level.

Most of the deposit methods also serve as withdrawal methods. The first payout, however, takes longer because players have to undergo a verification procedure for security purposes. The online casino processes payouts fast, but players will have to wait up to seven days to receive their winnings, depending on their preferred payment method.

Customer Service

Black Diamond Casino has an excellent 24/7 customer support system. Players can first check out the site's Frequently Asked Questions (FAQ) section for answers to commonly asked questions. If they still need assistance, they can open the live chat window or send an email to [email protected].

What we verify before a brand goes on a list

  • Licence on the regulator's register
  • Bonus terms as the operator publishes them
  • Withdrawal limits and stated processing times
  • Deposit rails that work from Australia
  • Limits, time-outs and self-exclusion tools

Pages on this site are compiled and checked by our editorial team from primary sources only: the operator's own terms, bonus and cashier pages, and the public register of the licence the brand names. We do not open accounts or deposit money on a reader's behalf, and we do not print a figure we cannot point to in writing – where an operator publishes nothing, the field stays empty instead of being estimated. The full method is set out in how we rate, and who stands behind these pages in our editorial standards.
