Double Diamond Slot Machine: Complete Home Buyer's Guide

The Double Diamond is not just a slot machine game. It is one of the most recognized names in American gambling history. Walk into almost any casino in the United States over the past 30 years and there is a strong chance you walked past a Double Diamond machine. Millions of players trace their first slot machine memory to this game.

That recognition is exactly why it is consistently one of the most requested home machines we sell at Used Slot Shop. When a buyer wants a slot machine for their game room, man cave, or basement bar — and they want something that feels genuinely, authentically classic — the Double Diamond is what they picture.

After 34 years of selling machines from our shop in Kingman, Arizona, we know this game better than almost any other machine we carry. Here is everything a prospective home buyer needs to know.

What Is the Double Diamond Slot Machine?

The Double Diamond is a game by IGT — International Game Technology — the largest slot machine manufacturer in the world. It is a three-reel, single-payline mechanical reel game. There are no bonus rounds, no free spins, no second screen, no progressive jackpot elements to configure. It is a pure, stripped-down slot machine experience built around one core mechanic.

The mechanic is this: the Double Diamond symbol acts as both a wild card and a payout multiplier. Land one on the payline and it substitutes for any other symbol to complete a winning combination, simultaneously doubling the payout. Land two Double Diamond symbols on the payline and wins are multiplied by four times — the two doublers combine. Three Double Diamond symbols represents the top jackpot of the machine.

That simplicity is the point. The Double Diamond does not need features to be entertaining. The anticipation of three reels stopping one at a time, the mechanical click of each reel locking into position, and the payoff of seeing matching symbols line up across that single payline — that is the entire game. It has been enough to make Double Diamond one of the best-selling slot machine games in American casino history.

The Platform: IGT S2000

In the home market, Double Diamond is almost exclusively associated with the IGT S2000 cabinet. The S2000 is the mechanical reel platform IGT introduced in 1996 as the successor to their S-Plus series. It improved on the S-Plus with better serviceability, a modular design that made component replacement easier, improved lighting, and a standardized game chip system that made swapping game themes straightforward.

The Double Diamond game chip plugs into the S2000 platform and, combined with the game-specific reel strips, converts the cabinet into a Double Diamond machine. IGT produced Double Diamond in very large quantities on the S2000. This means you will find more Double Diamond machines on the secondary market than almost any other individual game title — which is both a supply benefit and a testament to how much casino operators wanted this game on their floors.

Double Diamond Variants: What You Will Encounter

IGT produced Double Diamond in several versions. Understanding the differences matters before you buy.

Standard Double Diamond

The original and most common version. Three-reel, single payline. The Double Diamond symbol is the wild and the multiplier. Maximum bet is three coins. This is what most buyers mean when they say "Double Diamond" and what you will find most often in our inventory.

Double Diamond Deluxe

An enhanced version of the base game that adds a nudge feature. If a Double Diamond symbol stops just above or below the center payline, the machine automatically nudges it into alignment to complete a win. This feature increases excitement around near-misses significantly. Buyers who have played both typically prefer the Deluxe version. It commands a small premium because of this.

Triple Double Diamond

A variant that combines multiplier concepts from both Double Diamond and Triple Diamond. The machine includes both Double Diamond (2x) and Triple Diamond (3x) symbols. Two Triple Diamond symbols stacked on the payline create a 9x payout multiplier. This is the highest-variance version of the game — bigger potential payouts but fewer winning combinations. It suits players who prefer high-swing gameplay over steadier results.

Multi-Denomination Versions

Some S2000 Double Diamond machines were built as multi-denomination cabinets that let the player select the coin value (quarter, fifty-cent, or dollar) before play. These are less common but popular when available because they allow flexible wagering for different playing sessions.

Physical Specifications

If you are planning a purchase, you need to know what you are working with physically.

Upright cabinet: - Height: approximately 44 to 52 inches depending on the specific cabinet configuration - Width: approximately 23 inches - Depth: approximately 22 inches - Weight: approximately 250 to 275 pounds

Slant-top cabinet: - Height: approximately 24 inches (machine head only, without stand) - Weight: approximately 145 to 160 pounds for the machine head - Requires a separate stand to reach comfortable playing height

The machine runs on standard 110V/120V household current — the standard US wall outlet. It draws between 2 and 4 amps. No special wiring is required. We recommend using a surge protector and giving the machine its own outlet or sharing only with low-draw devices.

For doorway clearance, you need at least 24 inches of clear width to move an upright machine through a standard door, with 30 inches preferred. If your path to the game room involves tight turns or narrow halls, measure before delivery day.

Why the Double Diamond Is Ideal for Home Use

There are specific reasons this game consistently tops the home market, beyond simple name recognition.

Simplicity for Any Guest

The Double Diamond has no complicated betting structure, no multi-line selections, no bonus feature activations to explain. You insert money or press the credit button in free play mode, press spin or pull the handle, and watch the reels stop. Anyone from a child to an elderly guest can understand and enjoy this machine within thirty seconds. That accessibility matters for home entertainment.

Authentic Mechanical Reels

The S2000 uses physical spinning reels on stepper motors. The tactile experience of physical reels decelerating and clicking into position is something no video game or digital simulation replicates. Guests who have played only digital casino games are often genuinely surprised by how different this feels. That mechanical satisfaction is a significant part of the appeal for serious home buyers.

Free Play Mode

Every S2000 Double Diamond we sell can be configured for free play mode. In free play, you press a button to add credits without inserting anything. This eliminates coin handling entirely, reduces noise, and allows unlimited play for entertaining guests without managing currency. Many home buyers run their machines exclusively in free play mode.

Coin Operation Option

If you want the full authentic experience with real quarters dropping into the tray after a win, the coin operation system is fully functional. The hopper and coin acceptor are operational components. Playing in coin mode and hearing the payout coins hit the metal tray is a sensory experience that some buyers specifically require. You can also use casino-style tokens instead of quarters.

Low Maintenance Requirements

The S2000 platform is the most thoroughly documented and supported slot machine in the industry. Parts are available for every component. The platform is straightforward to service. In a home environment with moderate use, a well-maintained S2000 will operate for decades with nothing more than occasional cleaning, a bulb change here and there, and routine coin mechanism cleaning if operated in coin mode.

Legal Status: Every Age-Restricted State Approves

This is the cleanest legal picture of any machine we sell.

The Double Diamond on the IGT S2000 was manufactured from 1996 through the early 2000s. Every S2000 Double Diamond machine is now at least 25 years old. That is significant because 28 states allow private ownership of slot machines only if the machine is 25 or more years old — what collectors call the antique slot machine exception.

In 2026, any machine manufactured in 2001 or earlier qualifies under the 25-year rule. S2000 Double Diamond machines qualify in all 28 age-restricted states without exception. Combined with the 13 unrestricted states that allow ownership of any machine regardless of age, the Double Diamond is legal for private home use in all 41 states that permit slot machine ownership.

The nine states that prohibit private slot machine ownership entirely — Connecticut, Hawaii, Indiana, Nebraska, South Carolina, Tennessee, Wisconsin, New Jersey, and Louisiana — are the only places we cannot ship. If you are in one of those states, no machine from any dealer can legally ship to your address.

For details on how the 25-year rule works and what documentation you receive from us, see our antique slot machine laws guide. For your specific state, see our complete state-by-state legal guide.

How Double Diamond Compares to Similar Games

Double Diamond vs. Triple Diamond: Triple Diamond is the same S2000 platform with a 3x multiplier symbol instead of the 2x. Two Triple Diamond symbols on the payline produce a 9x payout multiplier. Triple Diamond is higher variance — larger potential wins but less frequently. Double Diamond suits players who prefer steadier, more frequent small wins. Triple Diamond suits players who like bigger swings.

Double Diamond vs. Red White and Blue: Another classic IGT single-payline game using patriotic symbol sets. The Red White and Blue does not use the wild-and-multiplier mechanic. Both are excellent classic games on the S2000 at similar price points. Double Diamond has significantly more name recognition. We sell both regularly.

Double Diamond vs. Blazing 7s: Blazing 7s features single, double, and triple Blazing 7 symbols with escalating top jackpots. It has a different visual aesthetic and appeals to buyers who prefer the traditional 7-themed look. Double Diamond appeals to those who want the clean diamond multiplier mechanic and maximum name recognition.

Double Diamond vs. Wheel of Fortune S2000: The Wheel of Fortune S2000 includes a physical motorized bonus wheel mounted on top of the cabinet that spins for bonus payouts. It is more expensive and mechanically more complex than the standard Double Diamond. If the bonus wheel interaction appeals to you and budget allows, it is a remarkable machine. If you want the pure, classic experience without extra hardware, Double Diamond is the better choice and a more reliable long-term proposition.

Maintenance Tips for Double Diamond Owners

The Double Diamond on the S2000 is one of the lowest-maintenance machines you can own. Here is the basic routine.

Monthly: Wipe down the cabinet exterior with a damp cloth. Clean the glass panels with standard glass cleaner. Confirm all indicator lights are functioning.

Every 6 months: Open the main door and blow out any dust with compressed air. If operating in coin mode, clean the coin acceptor mechanism with isopropyl alcohol on a lint-free cloth.

Annually: Check the reel strips for any peeling at the edges — this is rare on machines we have refurbished but worth a quick look. Verify the backup battery on the main board is still functional (the CR2032 cell maintains machine settings and game memory; if it dies you lose all configuration). Replace it preventively every few years.

Things to avoid: Cigarette smoke exposure, excessive humidity, power surges (always use a surge protector), and leaving the machine on continuously when not in use.
