Diamond Duke

Diamond Duke: Overview

It’s time to rewind the clock to the rock ‘n’ roll 1950s. Diamond Duke is set in a time when cars were huge and handled like boats, when Peggy Sue was yet to marry, and Sandy and Danny were trying to work out whether they liked each other. It was also the era of chrome, big lashings of the shiny stuff in diners, cars, and anything that could be bolted down. Being set in a less tech-driven era might make Diamond Duke look like a pared-back slot at first. However, it does have a couple of interesting features that can improve wins and produce a rather high potential.

This ultra-retro slot places the grid within an old-school style one-arm bandit that’s bathing in spotlights. Sitting on top of the machine are two intriguing bonus wheels. It’s all scaled down and it feels like Billie Holiday could wrap her hand around one of those vintage microphones at any moment and start crooning. The soundtrack reinforces the vibe with a smooth, laid back old jazz track. All up, Quickspin has done a nice job of creating a relaxed scene to insert quarters and spin.

The 1950s were supposedly a simpler time, so players get a simple 3×3 slot to relive it. And gone all out with the classic approach they have indeed. This applies to the symbols which are familiar favourites, (or despised generic), tiles of the genre. In ascending order, there are cherries, grapes, melons, bells, sevens, and diamonds. Values range from 3 cherries at 1x the stake, to 3 diamonds worth a sweet 160 times the stake. There are 5 fixed paylines in total, and with the symbols being stacked on the reels, a grid of diamonds will net you 800 times your stake right there. This is enhanced further by the features as we shall see.

Before getting to the best parts, the underlying math model warrants an inspection. Fortunately, the old fashioned outer shell reveals a bunch of thoroughly modern stats running the show. First up is the always important RTP which has been rated at the wholesome level of 96.23%. Quickspin’s volatility is measured from 1-5, and Diamond Duke musters up the full 5, so it’s a highly volatile game. So far, two thumbs up from the Fonz. Getting in on this sock hop is ideal for low rollers who can select bets from just 5 p/c per spin, or, ratchet that up to £/€100 should the mood strike.

Diamond Duke: Features

Pick and click bonus

In keeping with the multiples of three angle, Diamond Duke comes with three additional features. Each one is tied to the bonus wheel which can dole out some sizeable multipliers or crack open the bonus Pick & Click feature.

The key to the Bonus Wheel is the wheel scatter symbol – 2 of these symbols in view awards you 4 times your bet plus 1 spin of the bonus wheel. The bonus wheel then awards either a multiplier of x2, x3, x5, x7, or x10, or the Pick & Click Bonus game. Any multipliers won are applied to the total win.

The Pick & Click game is a simple choosing game with 3 stages containing coin wins based on your stake. Players continues making picks until they reveal either the upgrade symbol, which moves them up a level, or the collect symbol which ends the feature. The stages are set up like so:

  • Stage 1 offers prizes between x2 and x7 the bet.
  • Stage 2 offers prized between x3 and x15 the bet.
  • Stage 3 offers prizes between x5 and x100 the bet.

Should you manage to land 3 wheel symbols, then you are rewarded with 8x the stake, one spin on the bonus wheel, and one spin of the Multiplier Wheel. When this happens, players first go through the steps mentioned above. Once that is complete, they take a spin on the multiplier wheel to apply an extra multiplier of x2, x3, x5, x7, or 10x to the total win. In this way, substantial wins are capable of building up on top of each other before heading back to the base game.

Diamond Duke: Verdict

For what it is, Diamond Duke is a rather charming wee game. If you happen to be in the mood for a simple 3 reel slot, it might be worth a look. The soundtrack is a standout and alternates agreeably between laid back during the base game, and up-tempo during features or big payouts. Diamond Duke is not the most striking game visually. Still, it achieves Quickspin’s stated goal of transporting players back to the ‘heyday of American diners and classic cars with chrome and wings.’ After playing, you do get a hankering for some pancakes and a milkshake as the developer suggests.

Not only has Quickspin done a nice job of recreating the 1950s, to a degree, but the math model and stats produced by the game are rather good too. For one, RTP and volatility are decent, but even better is the max potential which is surprisingly high and has been clocked at 8,000 times the stake. Perhaps one slight drizzle on the parade, is that this particular figure arose during 100 billion simulated spins. In other words, there is a chance Doc Brown will invent time travel before some lucky punter picks it up. Then again, you just never know, and the dual multipliers and the Click & Pick are technically capable of juicing up wins.

Overall, Diamond Duke is quite a good example of a basic slot with a few useful extras. You don’t always see multiplier action on this scale with a game like this, so if you are after some 3×3+ gameplay, Diamond Duke might fit the bill.
