Diamond Casino is an unoriginally named game, but it has a lot to offer those who seek out its riches from within its diamond-encrusted network of symbols. From free games to enigmatic wilds, this slot machine is one of the brand’s better classic examples.

Quiet and Unassuming

Rather than screaming from the rooftops about how wonderful it is, this game comes in quietly and with a lot of grace; most fitting for the design chosen. Just as any diamond would, it is subtle in its brilliance and is without the need to flaunt or over represent itself – it knows its worth.

As a result, the interface is simplistic in both layout and design, although the dated graphics are still pleasing on the eyes, especially when you locate one of the gemstone icons. The mix of card values and exclusive imagery marries both past and present slot gaming together, therefore creating an environment that all gamers can appreciate.

In regards to the controls, they’re kept straight to the point and without fuss; such appears to be the Merkur way.

Alluring Charm

No jewel on this earth can be said to be as stirring as the diamond, and so it makes perfect sense for the scatter icon of this game to take its shape; surrounded by a cosmic background, the shine of the gem is almost blinding.

For gamers looking to score more than just the cash part of the prize, they will need at least three symbols for the free games to begin. The amount of rounds you can win will never change, which seems unfair given the challenge presented when seeking out a five of a kind match. Nonetheless, with 15 games on the house, you have plenty of chances to get the credits flowing from the game and into your pockets.

Should you be unfortunate enough to never get a match of over three diamonds, you have a silver lining to fall back on: a match of two win. Two diamond icons will deliver a win between 0.10 and 20 credits, depending on what you bet.

Hidden Talents

A lady in white is also upon the reels, with her job being to substitute other icons for herself, in an attempt to make a winning combination for you. However, this isn’t the only job of the wild when it comes to Diamond Casino, for this lady has a trick up her sleeve: she can double your win.

For this to happen though, you will need two wilds to appear at the same time, and upon a winning line, only then will the multiplier be applied. As far as talents go, it’s a little underwhelming, but it offers additional variance that can be added to the games limited arsenal of features.

Affordable VIP

Possibly the most exciting part of this slot machine comes from outside of the paytable, from upon the control panel; rather than costing an arm and a leg, a mere punt of 0.05 will suffice. Normally games have to endure the deadly combination of a glamorous design and a less than accommodating pay-in, but Merkur have ensured that everyone can feel like a VIP when playing Diamond Casino.

As always, there’s room to breathe and increase your wager to 10 credits, but still that is a lowly sum for such an attractive online activity. High rollers out there have a maximum bet option to select, rather than the burden of (+) and (-) buttons, another ‘luxury’ for them to savour.

Special Treatment

We have to hand it to Merkur, for saying how extensive their catalogue of games are, they always seem to inject some individuality into each of their games, even a vintage slot such as this. A game of this design and calibre is well worth a three and a half star rating.
