Diamond Duke


Diamond Duke Slot Review

Diamond Duke is a classic slot from Quickspin with 3 reels and 5 paylines across 3 rows. Released in May 2020, this game can be played at online casinos such as Guts, Mr Green or LeoVegas.

Theme and general information

Diamond Duke comes with a classic one-armed bandit at the front and centre. Somehow, when we first heard the title of this slot, we expected a Wild West or mining theme for some reason. Instead, we get a super-retro slot machine all the way from the 1950s and jazzy lounge music accompanying the whole thing. The reels rattle satisfyingly, and we find classic slot symbols on the reels.

Graphically, this is certainly not the most sophisticated slot Quickspin has produced. It’s well done, but also relatively simple, which includes the reel symbols. Those are rather small and cramped due to the fact that the whole slot machine occupies the view. We suspect this looks better in portrait mode on a smartphone.

Anyway, reel symbols include cherries, grapes, melons, bells, lucky 7s and diamonds. The cherries pay out 1x our stake for 3 of a kind and diamonds fill up our pockets with a win of 160x our stake for 3 across a payline. It’s great when that happens!

Naturally, there is no wild in the game, but we do get the “Wheel” scatter, which can land on all three reels.

You can play this game from 0.05 to 100.00 per spin.

The Bonus Wheels

Above the reels, you will see two bonus wheels, which are triggered by the “Wheel” scatters. Land two scatters and you get a win of 4x your stake as well as a spin on the outer wheel. Here you can get a win of 2x, 3x, 5x, 7x or 10x your stake or you trigger the Pick & Click feature (more on that below).

Three scatters will give you a win of 8x your stake as well as a spin on the bonus wheel and one on the multiplier wheel.

Should you land a multiplier on the bonus wheel, the second multiplier wheel will spring into action and apply another multiplier of 2x, 3x, 5x, 7x or 10x the previous win. However, if you first trigger the Pick & Click feature, it will play out first and afterwards the multiplier wheel will spin to award you one of the above multipliers.

The Pick & Click Feature

If you trigger the Pick & Click feature via the bonus wheel, you will see a set of 9 light bulbs which you can pick from. You either get a coin win, end the feature or upgrade to the next level. There are three levels you can reach with ever increasing multipliers.

  • Level 1 – between 2x and 7x your bet
  • Level 2 – between 3x and 15x your bet
  • Level 3 – between 5x and 100x your bet

Once the feature ends, all your collected prizes are added up and if you triggered the multiplier wheel as well, it would now spin to reveal your final multiplier.

Verdict: A classic slot with some neat features at considerable potential

The theoretical RTP (Return to Player) for Diamond Duke is 96.23%, which is solid even though this is a highly volatile slot (maximum rating for a Quickspin slot). That means, you should budget carefully, which this game thankfully allows with it small starting bets.

That said, the features are triggered fairly often (or perhaps we were just lucky?), meaning the bonus wheel will spin regularly.

Whilst classic slots may not be Quickspin’s strength, this game is quite solid in execution and the features add the much needed extra to boost the potential, which is 8,000x our stake. That’s considerable for such an unassuming game and makes it worth your while. Sure, we never saw wins like that, but we caught three diamonds on a payline and clocked in the 100x multiplier on the third level once, which meant we happily stopped playing after we had one over 300x our bet in total.

More is definitely possible, though we did find the gameplay a little bit boring after a while.
