Diamond Discovery Slot Review

Diamond Discovery Slot Overview

Diamond Discovery is a video slot from SpinPlay Games where I head down a mine shaft in search of precious diamonds. The set-up is 5 reels, 4 rows, and 40 paylines, with a Min.bet of 0.20 and a Max.bet of 10, so it suits low and mid-stakes play. The theme is straightforward, but the gameplay revolves around collecting Diamond symbols and triggering several layered features.

On paper, Diamond Discovery looks very appealing. The slot runs at an RTP of 96.47% with high volatility and a max win of 25.000x the bet, which is far above many mining-themed games I have played. That mix of sharp swings and big potential fits the diamond-collecting mechanic well. From my sessions, the game feels simple yet engaging, with enough features firing to keep the spins from going stale.

Diamond Discovery Slot Information

The design in Diamond Discovery sticks with a simplistic mine shaft backdrop, lit by a single lantern hanging beside the reels. It is dark, but not oppressive, and the cheerful soundtrack gives the spins a lighter touch, even if the music does not perfectly match the gritty mining setting. I quite like that SpinPlay kept the interface clean, so the focus stays on the reels and the diamond meter.

Diamond Discovery runs smoothly on both mobile and desktop. A winning combination is created by landing 3 or more matching symbols on consecutive reels, starting from the leftmost reel, across the 40 fixed lines. That traditional line-based set-up will feel very familiar if, like me, you have played a lot of classic video slots. The game speed is brisk, and the controls are easy to get to grips with.

The lower-paying symbols in Diamond Discovery are gems in different colours: green, blue, pink, and red. Hitting five-of-a-kind with one of these pays 1x the bet. The higher-paying symbols are a lantern, shovel, plate of gold, and cart of gold, giving 4x to 10x the bet for a full line. An explorer acts as the Wild symbol, substituting for regular paying symbols, while a barrel acts as the Scatter.

Diamond Discovery Slot Features

Feature-wise, Diamond Discovery packs in several mechanics without feeling cluttered. The key extras are the Wild Symbol, Scatter Symbol, Diamond Symbol, Random Reveal Symbol, Piggypays, and Free Spins. Wilds can land anywhere and substitute for regular paying symbols, and on any spin there is a chance all Wilds upgrade to Diamond Wild symbols, which count as both a Wild and a Diamond for the collection feature.

The Diamond symbol is the core of the game. Landing 5 or more Diamonds in view awards a cash prize, with a dedicated diamond paytable displayed on the left side of the reels so you can see exactly what each number of Diamonds is worth. Random Reveal symbols can also land and then transform into the same symbol type, often setting up strong line wins or topping up the diamond count.

Piggypays in Diamond Discovery

Piggypays is the twist that gives Diamond Discovery its extra punch. Landing 1 to 4 Diamond symbols on a spin will increase the Piggypays meter. On the diamond paytable you will see multipliers starting from 8+ Diamonds. When you finally land 8 or more Diamonds, the stored Piggypays value is multiplied by the current diamond payout level, so lining this up at 10 or 12 Diamonds can produce hefty hits.

Free Spins in Diamond Discovery

The Free Spins feature in Diamond Discovery is triggered by landing 3, 4, or 5 Scatter symbols (the barrel) anywhere, awarding 10, 20, or 50 Free Spins respectively. During Free Spins, every Wild symbol appears with a Diamond attached. That means each Wild both substitutes for regular symbols and contributes to the Diamond collection, making it far easier to reach the higher steps on the diamond paytable.

From my play, this is where the slot really wakes up. You can walk into the bonus with a decent Piggypays meter already built, then use the extra Diamonds from Wilds to sprint towards the 8+ Diamond thresholds. Long streaks of Free Spins, especially when you hit 20 or 50, give the game space to show what it can do, turning a fairly calm base game into something much more explosive.

Diamond Discovery Slot Final Thoughts

Diamond Discovery manages to feel both straightforward and satisfying. The diamond-collecting, Piggypays meter, and Free Spins work together nicely, rather than sitting as separate ideas. The stats are strong, with a high RTP and a serious 25.000x max win on the table, and I have few complaints beyond the fairly plain artwork and lack of a bonus buy. For a mining slot, it stands up very well in practice.
