How To Play Black Diamond

Black Diamond is a three-reel game with nine paylines. The slot machine follows a classic style of gameplay, which makes it a great choice for beginners as well as more experienced players. The simple paytable unveils the rewards on offer for three or more of the game’s symbols on an active payline.

In terms of graphics, the game keeps things classic. A dark, moody backdrop gives the classic symbols the chance to shine. Symbols on the reels include sevens and bars in a variety of bold colours, from reds and purples to glittering golds. There are also diamond logo symbols on the reels. If these appear in a trio, a progressive jackpot will be triggered.

Black Diamond has an entertaining soundtrack which adds to the overall experience. The soundtrack plays as the reels spin and every time a winning combination appears the game burst with celebratory noises.

With a maximum bet of one coin per line, you really just have to decide what coin denominations you would like to use. Coin sizes range from just 0.01 all the way to 5.00, which means players can bet up to 125.00 coins per spin. 0.25 coins is the minimum bet necessary to cover all paylines.

The game’s jewel and gemstone theme is an oldie, but a goodie! The theming is true to the slot’s classic style and brings the gameplay together in an authentic way. This slot machine will appeal to lovers of classic online slots and those out for big progressive prizes.

Black Diamond Jackpots and Bonuses

Black Diamond offers players several chances to win significant real money prizes. The game’s two top prizes are the minor and major progressive jackpots, and these are available to win from within the base game. To trigger the progressive prizes, players need to line up three or more of the game’s logo, featuring a brilliant sparkling diamond in its centre.

If three of the logo symbols appear on paylines 1-8 and the maximum bet has been placed, then a minor progressive jackpot is triggered. If the symbols line up on payline 9 during a max bet spin, the prize gets taken up a notch and becomes the major progressive jackpot. Depending on how recently the prize has been won, this has the potential to pay out a life-changing sum of money.

Black Diamond also has special symbols, such as wilds. The game’s logo doubles as the wild symbol and it can be substituted for any other to help create winning combinations. While there are no bonus rounds or other complex features in this game, the progressive prizes and wilds provide plenty of exciting opportunities as the reels spin.

Black Diamond Mobile Options

Black Diamond is available to play on mobile devices, thanks to high quality mobile-ready software. The Everi game can be played on iPhone, iPad and Android devices, and there’s no need to download a specific app to do so. Players can access the game and all of its unmissable features via many well-regarded mobile casinos, all of which can be found via the mobile web browser. The graphics and gameplay on mobile devices is just as slick and speedy as it is on desktops, and the same huge prizes are available to win on mobile too.


Black Diamond is a classic-looking game with some impressive features. The progressive jackpot is, without a doubt, the main attraction of this game. But there’s more to Black Diamond than the major progressive prize on offer. The subtle, classic style of the game will be a huge hit with lovers of traditional online slot machines, who prefer fast-paced games without the distraction of bonus rounds and special effects. The soundtrack is a great addition to the gameplay, and mobile-ready software makes it a great choice for those who enjoy playing on a smartphone or tablet.
