Double Diamond — IGT's Defining 3-Reel Classic

Double Diamond pokie by IGT — 3-reel single-line classic with Diamond wild

Double Diamond is the pokie IGT built in the late 1990s that became, for an entire generation of casino-goers, what a pokie looked like. Three reels, one payline, cherries-bars-sevens paytable, with a single stylised Diamond symbol acting as a wild multiplier. No free spins. No scatter. No bonus round. Nothing to learn, nothing to wait for. Pull the lever, watch the reels, collect the payout. The whole session is the paytable and the rhythm.

Twenty-five years later, Double Diamond is still one of the most-played pokies on US casino floors — and the online HTML5 port has kept the classic feel intact. For players who find modern feature-heavy pokies over-engineered, Double Diamond is the palate cleanser. It's deliberately minimal, and that's the whole appeal.

At a glance

Pure classic 3-reel pokie. No features beyond the 2× Diamond wild multiplier. Low- to-medium volatility, fast spin pace, nothing to track between spins. The pokie you play when you want to just play a pokie — no modern mechanical overhead.

How Double Diamond plays

Three reels, one payline straight across the middle. The paytable runs from single cherries (lowest) through bar/two-bar/three-bar symbols, to double bars and the classic red Seven at the top. The Double Diamond symbol is the wild and the multiplier: any line containing a Double Diamond has its payout doubled, and two Double Diamonds on the same line quadruple the base payout.

Bet range runs from A$0.25 to A$125 per spin at most casinos, using 1-to-3 coin denomination selections rather than per-line bet steps. Single-coin play qualifies for all line wins at their base payout; two- and three-coin play unlocks higher paytable columns.

Bonus features

Theme, graphics and sound

Classic Vegas slot aesthetic — chrome reel frames, retro-diner colour palette of red, orange and yellow, with large block-letter BAR symbols and glossy red Sevens. Sound design is minimal: a crisp reel-stop click, a coin-drop jingle on winning lines, and a louder brassy fanfare for the three-Double-Diamond max-win. No background music — just the machine sounds. Intentionally sparse.

Mobile play

The HTML5 port is faithful to the land-based cabinet. On phones it plays particularly well in portrait — the vertical 3-reel arrangement matches the phone's form factor. No complex feature animations to translate to smaller screens; the pokie was always designed for clarity rather than spectacle. Autoplay is available but most players prefer manual spin for the pacing.

FAQ

What is the RTP of Double Diamond?
Approximately 95.44% on the online single-line variant. Some land-based cabinets at higher denominations historically ran above 97%, but those builds aren't represented in the online port.
Can I play Double Diamond with multi-line or multi-coin bets?
Multi-coin yes (1, 2 or 3 coins per spin, each unlocking a higher column on the paytable). Multi-line no — Double Diamond uses a single fixed payline by design.
Is Double Diamond the same as Triple Diamond?
No. Triple Diamond is a sequel with a different multiplier (3× single, 9× double) and slightly different paytable values. Same family, different maths.
Does Double Diamond have a progressive jackpot?
Not in the standard online version. Some land-based linked variants fed into progressive pools, but those aren't replicated in the standard HTML5 build distributed to AU-facing casinos.
