Three reels, one wild emblem, 1,000x — classic Vegas distilled
The Double Diamond emblem substitutes for every symbol and doubles any win it completes — two of them push the multiplier to x4.
A single cherry pays 2x and two cherries pay 5x in any order, keeping small wins ticking over between bigger hits.
Any combination of the three bar symbols pays x5, so the bars work as a group rather than needing an exact match.
Pick the coin value you want to commit — the game reads in half a minute, so there is nothing hidden in the paytable.
Select how many lines to stake, then leave the rest to the three reels.
Press spin, or switch on autoplay if you would rather not click every round.
Three Double Diamond logos on the line is the game's 1,000x moment.
Double Diamond concentrates its entire bonus economy into a single symbol. The game has no free spins and no bonus rounds; instead, the diamond emblem substitutes for anything on the payline and multiplies the result — x2 with one wild in the win, x4 with two. That turns an ordinary bar combination worth 5x into 10x or 20x, and makes the triple-emblem line worth 1,000 times the line bet the game's defining chase.
Put Double Diamond next to today’s cascade-and-feature machines and it looks almost defiant: three reels, one core payline, a paytable you can absorb in thirty seconds and not a free spin in sight. That is precisely the appeal. IGT’s Vegas floor staple compensates with pace — spins resolve quickly enough to build tension without dragging — and with a wild-multiplier emblem that quietly does the work other games need whole bonus rounds for.
The numbers: a 95.44% return, close to the industry’s 96% standard, delivered with very streaky variance. Long dry stretches are normal, broken by modest cherry-and-bar pays and the occasional multiplied hit of up to 800-1,000x the line bet. It responds well to careful bankroll strategies, but the risk profile deserves respect.
