Double Diamond is one of IGT’s most recognizable slots, and it’s displayed a great deal of staying power. The game remains popular at physical and virtual venues alike, thanks to a combination of interesting bonus features, a good top payout, and nostalgia.

If you’re thinking of playing this slot for the first time, your question is likely how much of the hype is nostalgia and how much is merit. While Double Diamonds shows its age in some ways, there’s still a lot to appreciate about the game.

What makes Double Diamond slot great

Double Diamond is still a great example of how to do a simple slot right, with bonus features that are exciting and easy to understand.

Easy to play, but rewarding: Enjoy simple gameplay with minimal options and get greater wins through a two-in-one wild and jackpot symbol.
High max payout: Earn 1,000x your bet when you line up three of the double diamonds.
Visuals that still hold up: While the sevens theme is well-trodden, the detail and vibrant colors on display ensure its graphics stand the test of time.

How Double Diamond slot could improve

While Double Diamond has a lot going for it, there are some key ways that it shows its age.

Reduce minimum bet: A minimum bet of $1 is much higher than the minimum bet that most modern slot games offer.
Improve the sub-par RTP: While 95.44% RTP was fairly good decades ago, it’s underwhelming today.
Add optional bonus features: Simplicity is part of Double Diamond’s charm, but a red/black wager game or other optional bonus features could increase depth while preserving simplicity.

How to play Double Diamond slot online

As a 3×3, single payline slot, Double Diamond is resoundingly simple to play. All you need to do is set your bet from $1 to $100, and three matching symbols on the center line win. There are multiple bar symbols, but any combination of them also awards a win. The other exception is the cherry, as any one or two cherries award a modest win.

You can try the game for free on this page and refresh if you run out of credits. If you decide to play Double Diamond for real, you can try a real-money casino like Caesars Casino or DraftKings. Many casinos offer deposit bonuses you can use for real money slots. See the links below for info on the latest bonuses.

Bonus and jackpots for Double Diamond (Rating of 3/5)

Double Diamond’s bonus features are the most underwhelming part of the game next to modern slots, but they do their job. There are two noteworthy bonus symbols: the double diamond wild and the cherry. The cherry works as a bonus feature because it’s the only symbol that can award a win without having three on the line, which helps keep the game interesting.

However, the wild symbol is the most important feature. Any win with a double diamond awards a double payout, while two double diamonds achieve a 4x payout. Lining up three double diamonds earns you the top payout in the game, a win of 1,000x your total bet.

Double Diamond graphics and visuals (Rating of 4/5)

You’ve likely played many slots with sevens, bar symbols, and the like, but Double Diamond gives them a polished look with good shading and lighting. There’s a rich variety of colors, with a retro-style background adding a bit of an old electronic feeling to the visuals. Overall, the visuals are one part of Double Diamond that stand the test of time surprisingly well.

Double Diamond gameplay (Rating of 4/5)

While fewer paylines increase volatility, Double Diamond counters this with some smart decisions. For instance, there are relatively few symbols, and some different symbols are compatible. This helps increase the visual variety and range of wins without making the game less visually interesting, and it doesn’t complicate the game much, either. It’s always easy to tell when you have a win and why. The only downside is that the RTP of 95.44% is a bit below standard.

Overall rating for Double Diamond by IGT (Rating of 3.6/5)

While the slot looks a bit old in more ways than one, there are good reasons for the enduring popularity of Double Diamond. While it’s not as flashy or deep as modern slots, this is part of its appeal, thanks to the way it balances old school simplicity with rewarding, balanced bonus features. Even the visuals hold up well, as the care and detail put into them has prevented them from drowning in the sea of lookalikes. Overall, Double Diamond receives our recommendation with a 4/5 final score.
