Diamond Link: Mighty Sevens Dice: six diamonds that can change everything

Six symbols. That is the line between an ordinary spin and a jackpot sequence. Diamond Link: Mighty Sevens Dice by Greentube, the digital division of Austrian giant Novomatic, is built around that single promise. Every reel spin can tip, within moments, towards one of the game's four progressive jackpots.

As one of the standout titles available at Loco Casino, a well-regarded casino Belgium platform that welcomes English-speaking players, this slot is well worth your time.

Playing Diamond Link: Mighty Sevens Dice — what you need to know before you spin

The grid is a straightforward 5x3 layout. Five reels, three rows, 25 fixed paylines. Nothing to configure, nothing complicated to get your head around.

Stakes range from €0.25 to €50 per spin. A broad range that suits both cautious play and more aggressive sessions. The displayed RTP is 95%, which is entirely consistent with progressive jackpot mechanics — a portion of the theoretical return feeds directly into the jackpot pool.

The Dice variant sets itself apart from the rest of the series through its retro dice symbols. These sit alongside the classic fruit symbols — cherries, lemons, oranges, plums, grapes, watermelons — without altering the game mechanics in any way. The visual identity feels sharper and more distinctive; the gameplay remains familiar.

The Wild substitutes for all regular symbols. It also represents the highest payout outside of the jackpot: 750 times your stake for a full five-symbol combination. On a €5 bet, that comes to €3,750 from a single spin.

The Diamond Link™ feature in Diamond Link: Mighty Sevens Dice — how it actually works

This is the heart of the game. The Diamond Link™ feature is what separates this online slot from a standard fruit machine.

To trigger it, you need six or more diamond symbols to land simultaneously on the grid. The mode activates immediately. Three respins are awarded. Every new diamond that lands resets the counter to three.

The grid holds fifteen positions. If every single one is filled with diamonds before the counter reaches zero, the outcome is definitive: Grand Jackpot triggered automatically.

Each diamond also carries its own monetary value. Those values accumulate throughout the entire feature. Even without reaching the Grand Jackpot, the payout can be well worth the build-up.

The four progressive jackpots, from the most accessible to the rarest:

Win Spins in Diamond Link: Mighty Sevens Dice — the feature that cannot lose

The second major feature in the game is called Win Spins. It triggers independently from Diamond Link™.

Land three Gold Star symbols — the golden Scatters — on reels 2, 3 and 4. Seven free spins are awarded straight away.

The logic is refreshingly simple. If a spin produces no winning combination, an automatic respin is launched. The spin is replayed until it delivers a win. That is exactly where the name Win Spins comes from.

During these spins, any diamonds that land on the grid lock into the Diamond Meter. The threshold of six diamonds needed to activate Diamond Link™ becomes considerably easier to reach. The two features can flow naturally into one another within the same sequence.

Why Diamond Link: Mighty Sevens Dice stands out among the popular slots

On Loco Casino, this title sits alongside other slots that have built their own loyal followings:

Diamond Link: Mighty Sevens Dice occupies a different space. It pairs the accessibility of a classic format with the genuine pressure of a four-tier jackpot. Any spin can shift things in seconds. That is precisely what makes it compelling.

What players take away from Diamond Link: Mighty Sevens Dice

The Diamond Link™ mechanic is precise and well-documented. Six diamonds to trigger, fifteen positions for the Grand Jackpot. The Win Spins ensure that no spin is ever entirely wasted.

The Gamble mode lets you risk your winnings on the colour of a turned card — a hallmark of the Greentube/NOVOMATIC catalogue, found across virtually all of their titles.

Diamond Link: Mighty Sevens Dice does not promise a jackpot every session. It promises something rarer: the persistent feeling that the Grand Jackpot is always within reach. Fifteen positions sit empty. The counter is at zero. Six diamonds are all it takes to set everything in motion.
