Diamond Discovery

by SpinPlay Games

Diamond Discovery from SpinPlay Games seems like a fairly predictable setup when you first arrive. However, there are a couple of interesting features that help set this game apart from some of its rivals. 

At the heart of the game are the diamond symbols, as you might expect, and then there is the addition of random reveals, Piggypays and a free spins round as well. It all adds up to become quite an exciting adventure and we're going to dig deep to see exactly what treasures are waiting to be unearthed.

Diamond Discovery Features

To hit the big time, those all-important diamond symbols need to show up more often than not. But there are plenty of other prizes up for grabs and several features that can trigger to give your balance a welcome boost. It is a fairly clever little setup and more importantly, it isn't too difficult to get your head around.

Wild Symbols

The wild symbols stand in and substitute for all others except for scatter symbols. They are pretty ordinary by all accounts. But occasionally, they get a little upgrade and have a diamond on them. This is always the case during the free spins round. Bear this in mind for when you trigger that feature.

Diamond Symbols

Diamond symbols bring forth great riches wherever possible! As they land, they either boost future prize-winning potential or give you an immediate cash prize. Find out exactly what those prizes are in the Piggypays section below.

Random Reveal

The random reveal symbols show up shrouded in mystery. You have no idea what they are until they suddenly burst into life and produce one of the other paying symbols. They will all morph into one and the same symbol which could produce a fantastic win.

Free Spins

3 or more scatter symbols will see you make your way into the free spins feature. And here, things could start heating up. Everybody gets 10 free spins as a minimum but it's possible to get 20 or 50 if you land more scatter symbols.

All of the wild symbols in this part of the game are upgraded and feature the exciting diamond icon. You will grab regular wins as the free spins take place and the diamonds will continue to do their thing over on the Piggypays ladder. Let's take a look at exactly what this is all about.


At last, we get to meet the star of the show. To the left of the reels is the Piggypays prize ladder. You will see that anything from 5 to 20 diamonds holds great significance with this feature.

5, 6 or 7 diamonds landing on the reels will simply boost the total by its respective prize listed next to it. But once you get over 8 diamonds appearing on the reels all at once, you hit an instant win. And the great thing is that these prizes are paid out according to the multiplier to the right.

Diamond Discovery - Free Spins

Free Spins

We all know how free spins work. But add extra diamonds to the wild symbols and that Piggypays meter could start to blow up and make those spins super valuable.

Diamond Discovery - Piggypays


1-5 diamond symbols simply adds to the Piggypays prize meter but 8-20 of them lands you a prize. Multipliers come along for the ride ranging from 1x to 1,000x.

Diamond Discovery - Random Reveal

Random Reveal

Watch a random symbol land with no recognisable image on it and you'll see it transform into one of the other paying symbols. This could create some top wins.

Diamond Discovery Review

This game is more about the prize-winning potential than it is about the production value. While the added features do create better winning possibilities, they don't add a huge amount to the storyline or the overall feel of the game.

This theme has been done a thousand times before so it was always going to be a tall order making it different from the rest. SpinPlay Games has had a good go at it but we feel like they could have gone further.


If you thought that this game would present an audio-visual display that might catch you by surprise, then you'd be a little disappointed. It features all of the regular elements that we've seen many times before. 

There is a less-than-inspired goldmine backdrop and the flashing diamond symbols are almost a little too futuristic for this production. The soundtrack is a simple banjo loop that you will end up switching off fairly quickly. It's not that this is a bad slot, far from it. The problem is that there is nothing different here other than a couple of nice features to really make it shine in an extremely crowded niche.


We might have been a little brutal on the design review but our experience of the game set-up was a little more positive. We liked the fact that it doesn't try to be overly complicated and the addition of some nice features helps keep things interesting along the way.

High volatility does mean that those features won't be triggered very often so you'll have to make do with the regular base game ticking over while you wait patiently.

Win Potential

One thing that this title does well is win potential. A massive 25,000x stake payout is available for some lucky players when everything comes together perfectly. The RTP is over what you might expect and sits at 96.47%. But be aware that this can change depending on where you play. 

You won't find regular wins but when they do come, they should be pretty decent and help replenish your bankroll somewhat. Prepare your budget accordingly and don't go too hard too soon if you want to last the distance with this slot.

Our Verdict

While we might not have given this slot too much in the way of glowing praise, there is nothing to dislike about it either. We enjoyed spinning the reels for quite a while and watching the occasional features appear. 

The win potential is staggering and the overall feel is quite pleasant. Diamond Discovery will certainly appeal more to those who are interested in payouts rather than production value. If you fall into that first category, then you may well find a new favourite in this SpinPlay slot.
