It’s old meets new with Diamond Duke, a rather cute little game from Quickspin. The grid takes its place within 50s-inspired diner dwelling jukebox, but instead of being pack with tracks, this machine is bursting with bonus wheels and multipliers. The grid is just 3 reels wide, decked out with classic symbols and distinctly lacking a Free Spins game. But don’t let a fact sheet make up your mind for you, find out how this old school game gives all the flashy modern slots a run for their money with prizes of up to 8,000 times the bet.

What is the theme of Diamond Duke slot?

There aren’t any heroes, heroines or adventures with Diamond Duke. Despite having a name that’s reminiscent of cheesy Mills & Boon novels, this game is all about 50s Americana. You’ll be transported to simpler times, when people fed coins into jukeboxes and drive-in cinemas were the height of sophistication.

The 3 reels are bedecked by exactly the symbols you would expect: Diamonds, Lucky 7s, and Cherries. But there are a few unexpected additions like Game Logos and Spinning Wheels. Above the grid is an animated meter, the dial of which slides up and down to land on different multipliers.

The game is shaped like an old school jukebox, but it’s housing a classic fruit machine. My only criticism would be that the already small grid is made to feel even smaller as it sits within a jukebox display, and the entire grid is set against a rather expansive midnight blue background. This succeeds on the style front, but fails slightly on the practicality side of things.

How to play Diamond Duke slot

Diamond Duke is designed to conjure up memories of an era set firmly in the past. But it contradicts this mission by concealing highly modern special features that will put a pep in your step.

Diamond Duke Full Grid Win

Full Grid Win

This is exactly as it sounds. Fill every grid space with the same symbol and you’ll get the game to pay out all the lines. Not only does this mean a nice little cash drop (the amount will vary depending on the value of the symbol you land), but you’ll also earn yourself a spin on the Multiplier Wheel (see next).

Diamond Duke Multiplier Wheel

Multiplier Wheel

This feature can be accessed in two ways. The first is by achieving a Full Grid Win (above), and the second is by landing 3 Wheel Scatter symbols. The Wheel will spin and award one of its multipliers to your stake. You’ll have the chance to scoop up a 2 x, 3 x, 5 x, 7 x, or 10 x multiplier prize.

Diamond Duke Bonus Wheel

Bonus Wheel

Two or three Wheel Scatter symbols will grant you a single spin of the Bonus Wheel. Here you’ll have the opportunity to pick up a multiplier prize (as with above the multipliers on offer are 2 x, 3 x, 5 x, 7 x, or 10 x), or you’ll successfully enter the rather exciting Pick & Click game (see next).

Diamond Duke Pick and Click

Pick and Click

You’ll need to land the star icon during the Bonus Wheel feature to make it here, but it will probably be worth the wait. This feature actually gives you the choice of hidden rewards. Make your pick and reveal multiple prizes, including to climb up to three levels. Each of the wins will be influenced by your stake :

  • Level 1 (a prize between 2 x and 10 x your bet)
  • Level 2 (a prize between 3 x and 15 x your bet)
  • Level 3 (a prize between 5 x and 20 x your bet)

But here’s the thing. At each level you’ll be given the option to collect or continue on to the next level.

What is the RTP on Diamond Duke?

There’s no need to be a high roller to give Diamond Duke a whirl. Players can get things spinning from as little as C$0.10 per click. That being said, those who enjoy the thrill of high stakes can play at a maximum of C$100. Regardless of how much you’re betting, the game always runs with just 3 reels and 5 active paylines in play. I initially turned my nose up at this, but thanks to the generous game mechanics, the small grid size actually worked in my favor.

The symbols carry very low values. In fact, a base game win will rarely go much higher than your bet amount. It’s only if you can land a full screen of matching symbols that you’ll achieve a sizable payout. The rest of the time you’ll be relying entirely on the multipliers awarded by the bonus wheel to come close to the game’s 8,000 x big prize. In terms of volatility, Quickspin’s taken a middle of the road approach. That doesn’t mean the game is without its risks, as even activating the special bonus wheel features won’t necessarily see you out with a huge win. Thankfully, with a solid RTP of and the RTP of 96.23% you’re unlikely to see your bankroll evaporate too quickly.

Final Verdict

Diamond Duke


The game is undeniably well designed. The gameplay is also put together in a very clever way so that you barely notice the absolute absence of a Free Spins game. But despite the features being fast paced and entertaining, I was particularly disappointed with the Pick & Click feature, which didn’t pay out nearly as much as it promised. The game’s 50s vibe was very pleasing, and the jive style soundtrack made decent background music. I also got a big kick out of the multiplier wins. Diamond Duke is a diamond game.
