Double Diamond is IGT’s classic three-reel pokie, born on land-based casino floors and now one of the most recognisable fruit-machine designs in online play. There’s no bonus round, no free spins and no animated storyline. Instead it runs on a single payline, a short symbol list and one wild that multiplies any win it helps create.
The game relies on a single mechanic, and it’s a mechanic worth understanding before you spin. The Double Diamond wild does nearly all the work, substituting for other symbols, doubling or quadrupling payouts, and forming the top prize when three land together. Some pokies give you something new every few spins. This one repeats the same focused loop every time, and that is either its charm or its limitation depending on what you want from a session.
The free Double Diamond demo on WinPockets lets you try that loop with virtual credits before wagering any real money.
How to Play Double Diamond
Double Diamond keeps things about as direct as online pokies get. Here’s the flow:
There are no feature menus to open and no side games to learn, so the whole game becomes clear within a few spins. It’s still worth checking the paytable once, because the cherry and mixed-bar rules affect how often small wins land. After that, the game asks nothing of you beyond choosing a stake and pressing spin.
Gameplay & Winning Combinations
Double Diamond runs on 3 reels and 1 payline. A win forms when matching symbols land across the centre line. A handful of exceptions make it a little more nuanced than simple three of a kind matches.
Because there is only one payline, every spin has one outcome that matters. That clarity counts as one of the game’s strengths, and you never need to scan across several lines to work out what paid. Either the centre row lines up or it doesn’t. The downside is that near-misses above and below the payline are common and meaningless, which can feel frustrating for anyone used to modern multi-line games.
What Are the Double Diamond Pokie Symbols and Their Values?
The symbol set is intentionally small and borrows directly from traditional mechanical fruit machines.
Double Diamond (Wild)
The top symbol on the reels, it substitutes for every other symbol and multiplies any win it forms part of. Three Double Diamonds together on the payline award the game’s top prize of 1,000x.
Red 7
The highest-paying standard symbol. It’s the one most players hope to see paired with a wild.
Triple Bar, Double Bar and Single Bar
These fill the middle of the paytable. Three matching bars pay more than a mixed combination. The Triple Bar pays the most of the three and the Single Bar the least.
Cherry
The lowest-value symbol, though the most forgiving one. Cherries pay in counts of one, two or three on the payline, and they account for most of the game’s small returns.
Exact credit values appear in the in-game paytable and scale with your stake. The value of any standard win can change significantly depending on whether one or two Double Diamond wilds help complete it.
How Do the Free Spins and Bonus Features Work?
Double Diamond has no Free Spins round and no separate bonus game. There are no scatters, no pick-me features and no Bonus Buy option. Everything the game offers plays out within the base spin, driven by the wild and a couple of paytable rules.
That will disappoint anyone expecting a modern feature set. It also means every spin carries the same potential, because nothing is locked behind a trigger.
Double Diamond Wild Multiplier
This is the game’s defining mechanic.
A single wild can turn a modest bar win into something worthwhile. Two wilds landing alongside a Red 7 or Triple Bar produce the strongest moments the base game offers. It’s a simple rule, but it still builds anticipation as the third reel slows to a stop.
Cherry and Mixed Bar Pays
These are paytable rules rather than triggered features, but they shape how the game plays.
These rules fill the gaps between bigger hits. They keep the balance ticking over during quieter stretches, though they rarely return much more than the stake on their own.
What Is the RTP and Volatility of the Double Diamond Slot?
Double Diamond has an RTP of 95.44% and medium volatility.
RTP is a theoretical figure worked out across a very large number of spins. It describes the game’s long-term mathematical return, not what happens in any one session. Results over a short stretch of play can land well above or well below that number.
An RTP of 95.44% is a little below what many modern online pokies offer. Medium volatility fits the game’s structure. The cherry and mixed-bar pays provide regular small returns, while the wild multipliers and the 1,000x top prize create room for larger, less frequent hits.
What Is the Max Win on Double Diamond?
The maximum win on Double Diamond is 1,000x your stake, awarded for landing three Double Diamond wild symbols on the payline.
That is a modest maximum by current standards, where many pokies advertise 5,000x or more. The trade-off is that the path to the top prize is completely transparent. There are no cascading multipliers or bonus stages to chain together, just three specific symbols needed on one line. Knowing exactly what you’re playing for counts for something, even if the upside is limited compared with feature-heavy releases.
What Are the Theme, Graphics & Sound of Double Diamond?
The presentation copies the look of the original IGT cabinet almost exactly. The reels appear against a plain backdrop, with the symbols made up of flat bars, Red 7, cherries and the diamond logo. The Double Diamond symbol itself is the most detailed element on screen, reflecting how central it is to the game.
Animations are minimal. The reels spin, stop one by one, and wins are highlighted along the payline. The sound design follows the same pattern, using mechanical reel noises and simple chimes rather than a music track.
The visuals read as dated but honest. Nothing distracts from the payline, and the design works because the game’s appeal is nostalgic and mechanical. Anyone who grew up with land-based pokies will recognise it straight away. Players used to cinematic modern slots may find it bare by comparison.
Play Double Diamond Free on Mobile
The free Double Diamond demo on WinPockets runs in your mobile browser, so there is nothing to download. The three-reel layout suits smaller screens well. With only one payline and a handful of symbols, everything stays readable in portrait orientation.
Touch controls are limited to the stake adjustment and spin button. The interface stays uncluttered as a result, and because the game has no bonus features, the mobile version gives you the full gameplay experience. Winnings from the demo cannot be withdrawn, since it runs on virtual credits only, and free-play results don’t indicate what will happen with real money.
Our Verdict
Double Diamond does one thing, and it does that one thing without clutter. The wild multiplier drives the whole game. It doubles a win, quadruples it with two wilds, or delivers the 1,000x top prize with three. The cherry and any-bar rules keep small returns flowing, and the single payline makes every result instantly readable.
Double Diamond lacks depth. There is no free spins round, no scatter and nothing that changes the pace of play over time. The 95.44% RTP runs below many newer releases, and the 1,000x cap won’t excite players chasing big multipliers. Over a longer session, the lack of variety becomes noticeable.
Still, this simplicity is exactly the appeal for the right player. If you like traditional fruit-machine pokies, value simplicity, or want to understand a genuine IGT classic, Double Diamond is worth your time. If you need bonus rounds to stay engaged, you’ll probably move on quickly. Trying the free demo is the easiest way to find out which camp you fall into.
