Double Diamond Slot Game Review
Double Diamond is one of those classic 3-reel slots I go back to when I want something simple and fat paying. It runs on a single payline, powered by IGT, and feels very much like the old stepper machines you still see in land-based casinos. No complex bonus rounds, no feature screens, just set your line bet, hit spin, and watch the BARs, 7s and cherries roll past.
The interface is clean and easy to operate. I like that I can tweak the wager quickly, use the autoplay option for up to 50 spins, and just focus on the base game. The whole idea here is multipliers rather than fancy extras. If you enjoy a basic slot playing experience, where the wild symbol is the real game changer, Double Diamond fits that brief perfectly.

Double Diamond Slot RTP
From a numbers point of view, Double Diamond has a published payout percentage of 95.44%. For a classic 3-reel slot with one payline, that is a pretty fair return to player in the long run. The game is set up as a high volatility slot, so it can go through stretches without much happening, then land a sizable win when the right combination finally drops on that centre line.
Betting is flexible enough for me to manage the swings. Stakes range from 10 credits up to 5000 credits, and the game really comes into its own when you play three coins on the payline, as the maximum 10,000-coin jackpot depends on that. I tend to keep coin values low so I can afford maximum coins and still give the slot a proper session.
Double Diamond Features
On paper, the feature list for Double Diamond looks very short. There is no separate bonus game, no free spins, and no progressive pot. Instead, you get a fixed jackpot of 10,000 coins, a wild symbol that carries multipliers, and a very straightforward paytable. The theme sticks to a classical slot style, and the game runs smoothly on mobile, tablet, and desktop devices with the same core mechanics.
Multi-currency support and the autoplay option make it feel just modern enough, but the structure stays old school. I actually like that there is nothing extra to track. Every spin is about lining up symbols on that single payline and hoping the Double Diamond logo gets involved. When it does, the multiplier effect on wins is what gives the title its main punch.
Double Diamond Theme and Unique Features
Double Diamond goes all-in on a classic casino vibe. The reels sit on a cool black background, with simple but eye-catching graphics for BARs, 7s, cherries, and the sparkling Double Diamond logo. The animations are kept to a minimum, which suits this style of slot just fine. It feels like an authentic old-school machine that just happens to run in a modern browser.
There is a melodious soundtrack that plays along with the spins, giving the game a bit of atmosphere without becoming annoying. What sets Double Diamond apart for me is how it sticks to a 3-reel, single payline layout, yet still offers strong potential wins through its multiplier structure. That mix of simple visuals, retro symbols, and high-impact multipliers is what keeps me coming back.
Double Diamond Bonus Features
The headline feature in Double Diamond is the wild symbol, shown as the Double Diamond logo. This wild can substitute for every other symbol on the reels, so it is the key to completing many of the better-paying combinations. If you have matching symbols on reel 1 and 3 and land the logo on reel 2, the wild steps in and turns a near miss into a proper win.
On top of substitution, the wild brings multipliers. One Double Diamond in a winning line doubles the payout. Two wilds in a winning line quadruple it. When you manage to hit three Double Diamond logos on the single payline, you are looking at the top prize of 1000 times your bet, or 10,000 coins when staking the maximum. There are no free spins, but this multiplier action more than makes up for that in my view.
Double Diamond Slot Payouts
Double Diamond pays entirely in multipliers of your total bet, which is one reason I rate it as a fat paying 3-reel slot. Standard symbols include single, double and triple BARs, 7s, and the classic cherry. Land three 7s on the payline and you collect 80 times your total bet, which scales very nicely when you push the stake. The Diamond logo is the highest paying symbol, with three awarding 1000 times the wager.
I like the way cherries work in this slot. They break the usual rule that you need three of a kind to get anything back. Hitting one cherry pays 2 times your bet, two cherries pay 5 times, and three cherries give 10 times. That creates a bit of action even on quieter spells. When the wild logo combines with other symbols, the game can throw up surprise wins thanks to the extra 2x or 4x multipliers.
The maximum win of 10,000 coins comes when you land three Double Diamond logos while playing three coins on the payline. No separate jackpot game is involved, so every spin has that potential baked in. Because all payouts are expressed as bet multipliers, the game scales well from small stakes right up to higher limits, as long as you are comfortable with the high volatility and the swings that come with it.

Our Double Diamond Slot Final Verdict
After plenty of sessions on Double Diamond, I see it as a pure old-school slot aimed at players who enjoy a traditional feel and are prepared for high variance. The gameplay is simple, almost brutally so, and the information section is not the most obvious, but once you get used to the paytable and the wild mechanics, everything falls into place. It is very much a case of spin, wait, and let the multipliers do their work.
High rollers who like classic slots will probably appreciate the flexible bet limits and the shot at 1000 times the stake, while low-risk players may find the swings a bit steep. For me, Double Diamond earns its popularity by stripping things back to three reels, one payline, and serious multipliers. If you want a straightforward slot that still has the potential to drop massive single-spin wins, this one is well worth a go.
