Black Diamond Slot Review
Black Diamond is a game that is tailor-made not for players who just want a retro-style slot machine, but players who want something that’s as close as possible to the old Vegas classics.
Everi Gaming provides fast reels, a clean design and customizable paylines to deliver a new machine that has the feel of the old antiques. While it lacks the flashy bonus features of other modern slots, the Black Diamond slot machine has a few tricks up its sleeves with potential progressive jackpots and multipliers.
Featuring a nostalgic design, this clean and simple design may disappoint players used to flashier graphics. The symbols are classic sevens and bars, although the single, double and triple sevens do come in separate colors to make them a little easier to keep straight.
The wild spaces add a little more variety with the Black Diamond logo adding a little shine to the reels. Their commitment to the old look goes as far as including blank spaces.
The sound effects stay true too, with only chimes and bells to signal the spinning wheels and winning paylines. The only modern allowance visible is that the spinning reels do glow red with excitement when a jackpot may be forming.

Black Diamond: Core Gameplay
This older style machine has a fairly focused number of ways to win. Black Diamond has three reels and three rows, with nine potential paylines. The paylines can stay visible on the screen to help players track potential wins as the reels settle.
This is particularly important because players can choose to player fewer than nine paylines if they wish. The game allows players to bet on one, three, five or seven paylines if they want to stretch out their buy-in. Although players cannot pick the specific paylines they want, each payline is already numbered and ranked one through nine.
The inclusion of blank spaces on the reels and the fairly small number of paylines means that payouts are a little rarer, but they tend to be a little bigger than other machines.
The only payout that’s below break even for a 9-line bet is an unmatched set of bars. The sets of sevens are a good payout on a normal payline, but the really big paydays rely on the jackpots and multipliers.
Special Features
Black Diamond offers a progressive jackpot for players betting the maximum amount of three credits on all nine paylines, for a total of 27 credits.
The Black Diamond spaces are normally just wild spaces, but if three of them fall on a payline they count as jackpot spaces. If they fall on paylines one through eight, it triggers the minor progressive jackpot.
Falling on the ninth payline, which is a V-shaped line through the top left, center and top right spaces, triggers the major progressive jackpot.
Players who don’t want to bet the maximum aren’t completely removed from the jackpot though. Hitting the minor jackpot when the bet isn’t maxed pays 300x the line bet, and hitting the major jackpot pays 5,000x the line bet.
One more way to win big is through the multipliers that can appear on the reels. Certain symbols will randomly appear with special multipliers stamped on top of them. If these special spaces fall within a winning payline, they multiple the line by that amount.
More important though, is that multiple multiplier spaces in a payline are able to stack all the way up to 30x for huge payouts.
Multipliers are never added to Black Diamond spaces, which means that jackpots can’t be multiplied. Although any symbol other than the wild spaces can have a 2x multiplier. Single bar and the single red sevens can also have a 3x multiplier. The 5x multiplier can appear on the double bars, yellow double sevens and blue triple sevens.
Old School Charm and Limitations
The Black Diamond machine is an oasis for fans of the old mechanical slot machines who want a little trip back in time.
Players who are tired of trying to hit it big in bonus rounds or interactive games will appreciate the simple mechanics. The 95.95% RTP also keeps it a good value for more seasoned players planning on a long run. Obviously, anyone seeking a little more style or fun bonus action will be disappointed and should try another game.
While the progressive jackpot and surprise multipliers provide a little of the fun from more modern machines, this game is all about watching those three reels fly.
Triple Double Diamond is one of variations of IGT Double Diamond slot series available at most gambling halls in the US and in the world. In a similar way that Bally’s Quick Hits are the most popular popular video slots, the Diamond ones are the most popular classic 3 reel slot machines.
Unlike the first Triple Diamond slot (yes, those names are a bit confusing), here you can enjoy some free spins and bonus games, which weren’t incorporated in previous slots in the series. Unfortunately, Triple Double Diamond slot is not available for free play, but below you can enjoy the free version of the original game.

Triple Double Diamond Slot Bonus Features
The Double Diamond and Triple Diamond symbols represent Wild and replace all regular symbols. The Double Diamond doubles payouts from the winning combinations in which it is included while the Triple Diamond triples winnings. Two Double Diamonds multiply a win by 4, while the combinations completed with the Double and Triple Diamonds deliver awards multiplied by 6 and so on.
Some Triple Double Diamond slot machines award free games while others offer a bonus game. To trigger these features you need to land three Scatters or three Hot Reel symbols anywhere on the screen respectively. Hot Reel is a craps-based bonus game during which a player should keep throwing two dice until he rolls a seven.
Verdict
Despite a plethora of video slots players can easily access from the comfort of their homes or on the move, classic slots at land-based casinos are still very popular. Being one of the leading companies which provide gambling halls with cabinets, IGT created a genuine classic slot machine with the bonus features which add excitement to the gameplay and boost your winning chances.
In contrast to popular classic slots, Triple Double Diamond slot offers 20 paying lines allowing you to create multiple winning combinations and win big, which is another reason to give it a try.
