Triple Diamond Slot Machine Overview

Triple Diamond Slot reels on mobile

Triple Diamond is the epitome of a classic Vegas slot machine. It’s the successor to the ever-popular Double Diamond, which was released in 2005 and is far from a new online slot these days.

Like most classic real money slots, the slot is no frills but comes packed with a huge jackpot and a very easy-to-navigate user interface. It’s accessible both online and mobile with demo play. Be warned that the free Triple Diamond slot machine is slightly different from the real-money game, with reduced coins and winnings.

On paper, it’s about as standard as they come with three reels and nine paylines. But IGT created a much more immersive feel, increasing the game to medium volatility and 96.5% RTP and upping the max payout (jackpot) to a 1,199 multiplier.

The upbeat sounds transport you to a 1970s Las Vegas casino, with classic symbols such as BAR, Lucky 7s, and just enough Triple Diamond Wilds to improve the gameplay and payouts.

How to Play Triple Diamond

One of the biggest draws to the IGT Triple Diamond slot machine is how easy it is to play. Here’s how to get started:

  • Set paylines: These range from 1 to 9, and the screen will show you the exact combination you get with each selection, making it easy to track as you play.
  • Line bets: This is the total amount you choose to wager per line. Next to this will be “Total Bet,” which will adjust accordingly as you change the number of lines and the amount wagered per line.
  • Auto spin: The auto spin button is in the bottom right corner. Here, you can choose from 10-50 spins to run automatically. It’s worth noting that the game will briefly stop for all payline wins before restarting. You can pause/stop this at any time.
  • Symbols: The game symbols include Lucky 7 and variations of BAR. You also have a Triple Diamond Wild, which is easily located on the board.
  • Sounds: You can mute or unmute sounds with the button in the bottom right corner.

Triple Diamond Slot Machine Payout and Symbols

The table below highlights the Triple Diamond slot machine payout for each symbol. To activate a combination, you’ll need three of the same symbols to appear on the payline unless it’s the wild that rewards for one or two symbols on the line as well.

Triple Diamond Wild 1 = 2x, 2 = 10x, 3 = 1,199x
Lucky 7 3 = 100x
Triple BAR 3 = 40x
Double BAR 3 = 20x
Single BAR 3 = 10x
Any BAR 3 = 5x

IGT Triple Diamond Slot Machine – Bonus Rounds

Triple Diamond slot machines are classics that focus on delivering high-paying combinations instead of bonus features. For some, it might seem uneventful, but that opinion only lasts until the first big win. 

The closest you get to a bonus round within the game is a jackpot triggered by three wilds, rewarding a massive 1,199x multiplier on your stake. 

Free Triple Diamond slot games are great to test whether it’s the gaming experience you’re after. Classics can be rather dull sometimes, so it’s well worth putting the game to the test before playing at real money online casinos

Triple Diamond Slot Review

The IGT Triple Diamond slot machine is a classic, which makes it easy to play and highly rewarding. Of course, the volatility is on the higher side, and that could result in loads of spins without any winnings before those worthy high payouts come your way.

Compared with other classics, Triple Diamond slot games score well. The game works nicely on mobile and desktop and has good graphics for winning payline combinations. It’s very easy to use, thanks to just having a handful of symbols and combinations to keep track of.

It’s definitely an upgrade on its little sister, Double Diamond. The slight increase in volatility and higher RTP means that it is much more immersive, with fewer smaller wins, which detracted from the original.

The standout feature is the Triple Diamond slot wild. This boosts multipliers and is the only way to secure the 1,119x multiplier by spinning all three across the same payline.

How to Activate the Triple Diamond Slot Machines Jackpot

Triple Diamond Slot Machine settings on mobile

The max jackpot you can win with the free Triple Diamond slot machines is a multiplier of 1,199x. This is on the high side for classics and is one of the slot’s strongest features.

Get three Triple Diamond wilds across three reels connected with a single payline. Free Triple Diamond slot games also allow you to activate the jackpot, but you might wish it was for real money when it happens. 

You can win the jackpot at any time, and like all online slots, it’s a random outcome as to when it will drop. If you’re new to slots, it’s worth noting that your chances of winning the jackpot for each spin are the same, even if it just dropped the previous spin.

How to Play Triple Diamond on Mobile/Apps

Landscape Triple Diamond slot machine in landscape mode on mobile

You can play real money and free Triple Diamond slot games on mobile. The game’s layout will depend on your browser, but as most online casinos are mobile-browser-based these days, removing the need for a casino app, it works on all makes and models.

The game is accessible in portrait and landscape mode. You’re more likely to use the portrait version of the game for ease, but for usability, it’s undoubtedly better in the landscape.

One of the only niggles that we have with the slot is that, unlike most new online slots, it doesn’t render as full screen vertically. So, the game still wants to be landscape and instead squeezes into portrait mode. Hence, our recommendation is to use landscape, where possible, on mobile.

It’s worth noting that the game’s bones don’t change whether you play on mobile or desktop. All features and bonuses, as well as graphics, sounds, paylines, and min/max bets, remain the same.

  • Triple 7 Slot (IGT)Like Triple Diamond slot machines, IGT’s Triple 7 slot keeps it classic with three reels and five paylines. Luckily, you’ll have multipliers, wilds, and free spins to look forward to.
  • 777 Slot Classic (Casino Web Scripts): This classic theme has more heart, thanks to 25 paylines over five reels. It is more than a few steps closer to modern games, featuring free spins, a progressive jackpot, a bonus game, and special symbols.

Triple Diamond Slot Review – Conclusion

The Triple Diamond slot machine is one of the better ones we’ve tested in the classics category. The 1,199x multiplier is the star of the show here, and with a large max bet, it means jackpot wins will be substantial.

It’s a step up from the original Double Diamond regarding gameplay and jackpots. The medium velocity and 95.06% RTP keep it right in the sweet spot for players who want to get value from their time with the slot while having the chance to win big from the jackpot.

As listed throughout our Triple Diamond slot review, the game has many strengths. Those new to slots won’t be overwhelmed by features and the crazy number of paylines, but those more seasoned will enjoy the balance between frequency and volume of payouts.
