Initially developed for brick-and-mortar casinos in Las Vegas, the Double Diamond slot machine has now been brought online by IGT so that you can enjoy it at online casinos from the comfort of your own home.
If you enjoyed the Triple Diamond slot machine free play, then you’ll love Double Diamond from the same developer, IGT. It has the same amazing vibe about it that will keep you spinning its reels for hours. No one could have ever thought about better symbols for Triple Diamond slot than IGT.
Dubbed ‘the dazzling hit that launched a gaming revolution’, on first appearances it will seem rather outdated to many of you who are used to playing 3D slots, however it will appeal to those of you from an earlier generation who are used to the simplicity and quick gameplay of traditional slots – plus it offers a generous 95.44% return to player percentage so you should see a better return than most online slots.
How it Works
Don’t worry just because it only contains 3 reels and 1 payline, Double Diamond still functions how online slots work most of the time. With one payline there are no options to adjust, however you can adjust the stake amount from £10 up to a maximum of £1,000 – though this will vary from casino to casino. You can also activate the ‘auto spin’ option that plays a pre-set number of spins rather than you clicking the spin button each time – with up to 50 spins allowed to be spun automatically. You might want to check the settings and turn the horrible cranking noise of the gears churning too – it’s quite unbearable!

6 Symbols On View
If you’ve played fruit machines before, especially those that only offer three reels and one payline, you’ll know not to expect many different symbols on the reels. The Double Diamond slot machine is no exception as there are only six symbols in total – with the usual suspects popping up.
Firstly, there is the Double Diamond logo itself which is the Wild symbol in an oval shape with two sparkling diamonds encased with ‘Double Diamond’ text. The other five will be all too familiar to you if you’ve played fruit machines before with a 7, tripe bar, double bar, single bar, and cherries all completing the range of symbols you will encounter when the reels are spun.
3 Double Diamond’s for 1,000x!
Now that you are fully aware of what symbols to expect when the reel’s spin in Double Diamond, it’s time to look at the various winning combinations that are available to – ranging from a mere 5x win up to a staggering 1,000x win – just don’t tell the wife or she’ll be wanting her wedding ring upgraded!
As you’d expect it is the Wild (Double Diamond logo) that brings the biggest perks of all. Not only does it match any other symbol on the payline to provide you with the highest possible win, if one Wild contributes to a win you’ll be paid 2x, while if two Wild symbols contribute to a win you’ll be paid 4x instead. Should you get really lucky and land three Wilds at the same time, it’s a whopping 1,000x that will see you beam as bright as a diamond!
This is in stark contrast to the lowest payouts. For example, one cherry on the reels pays 2x, two pay 5x, and any bar pays 5x too. Combinations of three symbols see the payouts gradually increase as three cherries pays 10x, three single bars pay 10x, three double bars pay 25x, three triple bars pay 40x, and three 7’s pay 80x – so there is certainly plenty of opportunities to win big in Double Diamond!

Not Bad for 3 Reels…
If a simple spin of the reels with quick gameplay is your preference the Double Diamond slot machine will be quite enjoyable, however if you are more used to slick and modern slot machines packed with free spins modes, second screen bonus games, and pick ‘em features this is a slot to avoid – heck there is not even a gamble feature and that’s very uncommon nowadays!
There have been different versions developed since this 3-reel version with a 5-reel version also available from IGT, however there are countless other fruit machine slots available to play online that are more modern than Double Diamond and also contain more reels and paylines – as well as bonus features for the opportunity to win more cash. For example, the Xtra Hot slot machine from Novomatic has an ‘X Feature’ and NetEnt’s Dazzle Me slot machine boasts Linked Wilds and Dazzling Wild Reels – you can’t go wrong with either of them!

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.
