Released by Greentube, the subsidiary of Australian gambling giant, Novomatic, Diamond Link: Mighty Sevens is a fresh addition to their Home of Games collection. The Diamond Link series is top-rated in the online gambling community, mainly due to their substantial collective jackpots and impressive re-spins.

Gameplay and Design

If you’re a fan of fruit slots, you will surely enjoy this game. Mighty Sevens borrows all the traditional elements from classic casino games and blends in the unique Diamond Link feature on a board with five reels and 25 pay lines.

The bets range from C$0.25 to C$50, which lets you wager up to C$2 per line.

Mighty Sevens is a typical classic fruit slot that has some clean looking symbols, which were remastered from retro casino games.

This slot features icons like Gold Stars, Diamonds, Triple 7s, Wild Logos, Bar Logos, Cherries, Lemons, Melons, Grapes, and Plums. The symbols pay from left to right, and you need at least three consecutive ones (except for the Gold Stars and the 7s) to make a winning combo.

Bear in mind that malfunction voids all pays and plays. Please consider reading the slot’s rules before making any bets.

To pay tribute to retro slot machines, the game’s highest value symbol is the lucky Seven, which can cover all the reels after any spin and bring you 750 times the stake. The RTP is quite low, at 95%, which is something typical to progressive jackpots in general.


Diamond Link Feature

Amongst the fresh and colorful fruit symbols, you can find the treasured Diamonds, which can trigger the Diamond Link feature. Essentially, if you collect six Diamond symbols, it will grant you a chance to win one of the four available jackpots: Mini, Minor, Major, or Grand. Here’s how this feature works:

  1. You receive three Free Spins during which you can land diamonds;
  2. Any diamond will be held in place and turn pink. The value of each symbol is displayed next to it;
  3. The reels start spinning again. If you land another pink Diamond, the free spin counter is reset. If no Diamond symbol lands, the next free round starts;
  4. If you manage to repeat the process until you’ve found 15 Diamonds, you will win the Grand jackpot. Fewer diamonds might award you one of the other available progressive jackpots.

The game shares the jackpots with the other Diamond Link slots, meaning the payout potential can get exceptionally high. Good luck landing the 15 special symbols!

Don’t forget to try out the other Diamond Link titles by Greentube, like Mighty Elephant or Oasis Riches.


Mighty Seven Special Features

Additionally, this slot comes with the traditional Gamble feature and Wild substitute symbols that can help you land some lucrative combinations. Still, it won’t help you trigger the bonus.

Mighty Sevens wouldn’t be a Diamond Link title without the impressive Gold Star Win Spins feature, that can be triggered by landing three scatter symbols. The feature will award you seven free spins with re-spins if there aren’t any wins.

Moreover, the free spins come with unique Diamond icons that remain in the diamonds counter until the end of the round. This fantastic game mechanic can increase your chance of triggering the Diamond Link feature.
