IGT initially released Double Diamond in the 1990s as a physical slot machine. Its straightforward gameplay and charm quickly earned it a loyal following among players seeking a classic slot experience. Building on this success, IGT brought Double Diamond to the online world in 2005 with a simple design featuring three reels and a single payline. Decades later, this iconic game continues to captivate players with its nostalgic appeal.
Double Diamond sticks closely to traditional slot design, built around the look and structure of classic three-reel machines. The presentation leans into that retro identity, aiming to recreate the feel of older land-based cabinets rather than modern video slots.
The symbol set reinforces this approach. Familiar icons like BARs and Lucky Sevens dominate the reels, keeping the visual style rooted in old-school slot heritage.
Audio follows the same direction. Sound design stays relatively understated, with mechanical reel clicks and a light retro backing track that echo the feel of physical machines without adding much theatrical flair.
The simplicity of play is one of this slot’s greatest strengths. Unlike most modern classics with multiple paylines, Double Diamond only has a single horizontal line. To form a win, you must match three symbols on a line.
Here’s how the symbols pay out:
This slot’s namesake, Double Diamond, is the wild symbol in the game, which helps to create a win when it appears with any other symbol on a line. Wins completed with one and two Double Diamonds can reward you with payouts of up to 2x and 4x your stake. This slot stays true to its classic format by omitting scatter symbols entirely. Of course, that means no free spins.
The Double Diamond online slot offers a RTP percentage of 95.44%, slightly below the industry average of 96%. When it comes to volatility, this IGT slot is on the high side, with wins often requiring some patience. However, the higher variance of this game means the potential rewards are rather substantial when lady luck is on your side.
Spending time with Double Diamond is more about settling into its simplicity than chasing constant action. The visuals are clean and functional, staying true to the classic slot aesthetic. After setting my stake, I spun through several rounds to get a feel for the volatility – and as expected with a high-volatility, single-payline game, early spins produced little in the way of returns.
Eventually, I landed a mixed BAR combination – two BARs alongside a Triple BAR – which highlighted one of the game’s core quirks. Even non-matching BAR symbols can produce a payout, expanding win possibilities slightly within the otherwise limited structure. With only one horizontal payline in play, outcomes are straightforward and easy to track.
Double Diamond symbols remain the most valuable but appear infrequently, in line with their payout weight. My largest return came from a three-BAR combination, which, like other wins, can pay in either direction across the payline.
Many online casinos have dropped IGT classics in favour of newer titles, but you can find this fruit-themed slot at Casumo Casino. This gaming site is among the most reliable in Canada. It houses 20+ IGT titles, including Cleopatra Gold, Crown Egypt, and Lucky Larry’s Lobstermania 2.
Double Diamond is built for players who value simplicity and nostalgia over feature-heavy modern gameplay.

Overall, it’s a stripped-back slot experience – better suited to traditionalists than players used to modern video slot depth.
Double Diamond’s high volatility and single-payline structure make bankroll pacing especially important. Long stretches without wins are a normal part of the gameplay cycle, not an anomaly.
Because there are no bonus rounds or feature breaks, spins can blend together quickly – particularly when using autoplay. This can make it easier to lose track of time and spend during extended sessions.
The game’s 95.44% RTP also sits below modern slot averages, meaning losses accumulate slightly faster over time compared to higher-return alternatives.
Setting firm loss and time limits before playing helps keep sessions controlled – especially in a format where outcomes are quick, repetitive, and heavily chance-driven.
