Double Diamond Slot Machine Features

Double Diamonds is an excellent choice if you’re looking for an old-school mechanical slot online. To be successful in playing any casino game, except luck, you should know key features and what to expect.

Double Diamond Symbols

The Double Diamond slot machine is known for its classical mechanical gameplay and the number of symbols used.

  • Classic symbols: There are only five symbols, including cherries, 7s, BAR, double BAR, and triple BAR.
  • Double Diamond symbol:  The Double Diamond symbol gives the game its name and is the most valuable. It acts as a wild and substitutes for any other symbol. The Double Diamond symbol also acts as a multiplier.

Double Diamond Paytable

As mentioned, The Double Diamond symbol replaces any other symbol. Also, wins with one Double Diamond pay 2x, while wins with two Double Diamonds pay 4x.

The rest of the paytable is as follows:

  • Three Double Diamond symbols: 1,000x
  • Three 7s: 80x
  • Three Triple Bars: 40x
  • Three Double Bars: 25x
  • Three Single Bars: 10x
  • Three Cherries: 10x, Two Cherries: 5x, One Cherry: 2x
  • Three of any Bars: 5x

Double Diamond Slot Machine RTP & Volatility

The return to player (RTP) of the Double Diamond slot is 95.44%. That means for every $100 wagered, the machine would theoretically pay $95.44. Every casino game will have a house edge, and generally, a good RTP in slots is above 95%. That puts the Double Diamond slot machine right on par.

Another critical feature is volatility, which tells us how often and how much a slot pays. A low volatility slot will pay often but small sums, while a highly volatile slot will pay larger amounts but less frequently. The Double Diamond slot’s medium volatility means it falls in the middle, so expect good payouts relatively often.

Double Diamond Slot Strategy

Many players love the Double Diamond slot because of its simplicity. You have a 3×3 grid with only one payline. Start with choosing your bet size. Different casinos offer different denominations, with some, like Golden Nugget Casino offering bets as low as $0.10, while DraftKings Casino offers the highest bet option of $250.

Once you have chosen your bet, just press the yellow spin button. Also, if you’d like, there is an autoplay option for you to take advantage of. If you land any of the paytable combinations, you win.

The Double Diamond slot machine is a mechanical slot, and it does not have any bonus rounds. The only bonuses include the cherry symbol, which pays even for one, and the Double Diamond symbol, which acts as a wild and multiplier.

Who Makes Double Diamond Slot Machines?

Double Diamond is one of the most popular IGT slots. IGT is one of the world’s biggest slot manufacturers, tracing its roots back to the 1970s and today boasting over 10,500 employees. IGT makes land-based and online real money slots, lotteries, and other gaming technology. Some of the most famous IGT slots include Cleopatra, Da Vinci Diamonds, Wheel of Fortune slots, and of course, the IGT Double Diamond slot machine.

Should You Play The Double Diamond Slot Machine?

The Double Diamond is an excellent choice for those seeking a no-frills experience. While it only has one payline, the medium volatility, and few symbols give you a good chance to win. While it does not feature a bonus round, you can score a huge win with a larger bet. Landing three Double Diamond symbols with a $100 wager gets you $100,000, while if you play at DraftKings Casino, a $250 bet can bring you a massive $250,000.

However, if you’re used to video slots with lots of features like free spins and bonus rounds, the Double Diamond slot machine might not be the best choice.
