It is one of the better ones we’ve seen.

Software: Quickspin

Maximum win: 8,000 x the total bet, or $€0.8 million

Betting range: $€0.05 – $€100

Casino Hipster verdict: Hot!

Diamond Duke reminds me of the beautiful ’60s, with those fantastic jukeboxes: Grease, Happy Days with the Fonz.

In those days, these kinds of slots were played.

But this slot has some exciting features.

And the first prize is not minuscule either.

You can bag a blistering and mindblowing 8,000x the bet

Yeah, if you bet a hundred, you can win 0.8 million.

Now that’s, what we are talking about.


Diamond Duke slot review

Diamond Duke slot – Gameplay and Features

The diamonds are by far the most lucrative symbols – three on a payline yields a prize of 160x the bet. Three sevens yield 12x the stake, three bells 6x the bet, and any 3-of-a-kind of watermelons, grapes or cherries are worth between 1x and 2 x the total stake.

You don’t have to be a mathematical engineer to calculate that a full screen of diamonds is good for a prize of 800x the bet.

Bonus Wheel

If you spin 2 “Wheel” symbols, you get a prize of 4x the bet. 3 “Wheel” symbols are worth 8x the bet.

But more importantly, you may now spin the Bonus Wheel. Here you have multipliers from 2x up to 10x.

If you’re lucky, don’t turn a multiplier on the wheel, but a yellow star. This activates the Pick & Click feature.

Diamond Duke slot bonus win upgrade

Pick & Click – flip coins, win big!

Now you can flip up to 9 coins.

There are prizes from 2x to 7x the bet (per coin). If you turn the coin with a white/blue arrow, you may proceed to the 2nd round. There you again have 9 coins, but now with prizes between 3x and 15x the bet.

Again, you can advance to the 3rd and final round if you get the white/blue arrow. Now, the prizes are between 5x and 100x the bet.

If you get a white/red cross before the white/blue arrow, then the party is over, and you get paid what you have collected so far.

Multiplier Wheel

These are activated with 3 “Wheel” symbols.

First, you get the Bonus Wheel as described above. But then you also get to whirl the Multiplier Wheel.

Here you’ll see what the multiplier is for the next spin. The multiplier is at least 2x and at the most 10x.

Yes, if you spin the 10x multiplier and you have the full screen of diamonds in the next spin, you have landed the prize of 8,000x the bet.

By the way, the chances of surviving a lightning strike ten times are much higher.

Payout percentage (RTP)

Diamond Duke’s payout percentage is 96.23%.

Not too shabby, but nothing too extraordinary, either.

The variance (volatility) of Diamond Duke is medium.

The variance is medium-high at the most.

Most top prizes will be around 200x to 400x the bet, with very occasionally an outlier of say 500x to 1,000x the stake. In the last case, you should already have a considerable multiplier and at least three diamonds on 1 or 2 paylines.

You can forget about winning higher prizes unless you are going to spin tens of millions of times.
