Diamond Shine

Diamond Shine Review

Diamonds and fruits mix surprisingly well on the reels of classic-themed online slots, creating expectancy of juicy wins and royal treasures. Just days after the release of its most recent fruit machine, Lithuanian game developer Onlyplay has come up with another one. Diamond Shine was launched at the beginning of July, heavily packed with special symbols and bonus minigames.

And if Royal Fortune Fruits was more advanced in terms of looks and mechanics, the game in focus today will cater to players feeling passionate about retro slots. Still, Onlyplay has added several jackpot prizes and a pair of bonuses to spice up the action and attract the gaze of younger gamblers. You can test all the features via the Diamond Shine free play mode linked above, or continue with my detailed review!

Onlyplay - Slot Developer

Onlyplay was established in 2020, and it’s already close to releasing its 200th title. The company is headquartered in Vilnius and operates globally due to partnerships with key operators and gambling authorities. Onlyplay is known to craft visually striking online slots and instant win games with innovative mechanics. The studio is often shortlisted for various iGaming awards. The latest accolade is the nomination in the prestigious “Innovator of the Year” category at the iGB Affiliate Awards 2026.

Slot Theme And Storyline

The Diamond Shine online slot comes with spectacular visuals, nice music and sound effects, and smooth gameplay. The vibrant background represents the radiance of space travel, while the gold-framed grid is designed in a classic style. Five winnable jackpots stand atop, offering solid payouts to the luckiest of players.

Diamond Shine keeps the anticipation growing with every spin, while offering an elegant gambling atmosphere. The provider definitely has a flair for style and elevates the classic, fruity slot experience to a new level. Due to the mechanics and technical characteristics of the game, every round is packed with tension and potential for big wins!

Diamond Shine Slot Rules And Gameplay

The Diamond Shine game offers a 5x3 gaming matrix packed with 25 lines, paying from the left side of the grid to the right. It is all standard with no special mechanics in this part of the machine. Autoplay and Fastplay are at hand, as well as a few other primary settings. The Diamond Shine slot is loaded with the normal betting range for Onlyplay slots, starting at €0.50 per spin up to €40.

Symbols And Paytable

Before going further with my Diamond Shine slot review, it’s time to explore the paytable! There are 8 regular and 3 bonus symbols - Wild, Scatter, and Diamond. Regulars pay for 3, 4, or 5 of a kind, and the same goes for the wild symbol, which can also replace any of them and complete winning combos. Scatters land on reels 2, 3, and 4 only, and if 3 are in view, they pay and trigger one of the bonuses.

How To Play Diamond Shine Slot At An Online Casino?

The Diamond Shine slot is already available for free and real money in numerous online casinos. Onlyplay has very good positions on many regulated markets, and it’s available in well-established and newly released platforms. There are several key criteria when selecting a new gambling operator, which you must never neglect. Check our expert guides to learn more about it, and here is what to do next to start a new online session:

Diamond Shine Bonuses And Special Features

Diamond Shine by Onlyplay offers several jackpots and a couple of bonus minigames. There are no base game modifiers, but my test showed that the wild symbol seems to be landing pretty often. Look for Diamonds and Scatters, as they are the keys to the minigames. Read the following lines carefully and learn everything about them!

Free Spins Bonus

As I already mentioned, the scatter symbol can land on reels 2, 3, and 4, and when it does on all three reels, it awards 8 free spins. Scatters can retrigger the feature in the same way during the bonus with no limit, but the slot’s max win cap. Free Spins is played with bonus symbols, wilds, scatters, and fruits only, and without the low-valued card royalties.

Bonus Game & Super Bonus Game

Six or more Diamonds in the base game or free spins activate the main Diamond Shine bonus round. It is based on the classic Hold & Win and includes 5 fixed jackpots listed below. The minigame starts with 3 respins and all triggering Diamonds are sticky, along with any other that may land. Respins are reset back to 3 every time a new symbol appears on the grid.

Bloody Diamonds can also land in the main game and free spins, but only on reel 5. If one of them and at least 5 regular bonus symbols appear, they will activate the Super Bonus Game. During the regular Bonus Game, Bloody Diamonds may land anywhere on the grid and even upgrade the minigame to Super mode, along with all Diamonds in view, which will get higher values.

Diamonds can carry cash values of 1x, 2x, 3x, 4x, 5x, 6x, 7x, or 8x the bet, while Bloody Diamonds carry rewards of 5x, 10x, or 15x. Both bonus symbol types can also carry Mini, Minor, Major, and Grand jackpot values. Mystery Symbol is in play only during the Bonus Game and at its end transforms into Mini, Minor, Major, Grand, or Super Bonus. Any of the Hold & Win modes ends when you run out of respins, or if you have 15 prizes in view. In the second case, you’ll also win the Royal Jackpot.

• Royal Jackpot – 10,000× the bet
• Grand Jackpot – 2,000× the bet
• Major Jackpot – 150× the bet
• Minor Jackpot – 50× the bet
• Mini Jackpot – 25× the bet

Strategy & Tips For Winning

Playing with a Diamond Shine strategy doesn’t only mean applying betting systems, but also organising the entire session in advance. You can still apply progressive techniques despite the relatively small number of available stake tiers. However, money management is far more important, as well as taking care of your emotions. Here are a few things to remember:

• Trust only casino operators with valid licenses.
• Do not skip the Diamond Shine free play practice.
• Claim a bonus that can help you play longer.
• Never borrow money to gamble and never chase losses.
• Play the Diamond Shine slot machine with a budget.
• Take regular breaks and keep your head cool.

The 200 Spins Diamond Shine Experience

Diamond Shine was generous in bonus triggers, but paid few solid payouts in the base game. In fact, it was just one - 30.50x the bet in the final part of my 200-spin test experience. On the flip side, I played the Bonus Game twice and won 11x and 18x the bet, and the Diamond Shine free spins once with a total win of 22x. The final result of my session was a loss of about 21%, which I consider acceptable given the fact that I played with flat bets and no advanced strategy.

Pros And Cons Of Diamond Shine Online Slot

Similar Slots To Try

Final Thoughts

Diamond Shine truly shines on our screens with premium visuals and well-selected audio tunes. It is the modern look of classic fruit machines, and surely that’s among its most significant advantages. There is room for improvement mostly in the technical specs, as medium volatility and a max win of over 10,000x will attract players, but not the payout rate.

At the same time, the Diamond Shine slot provides access to two of the most popular and widespread bonus minigames - Free Spins and Hold & Win. They are almost classic with minor modifications, which however, have the potential to greatly affect the gameplay. Still, there is nothing groundbreaking even in the Super Bonus Game. So, Diamond Shine will most probably cater to those already feeling enthusiastic about fruity slot machines!
