Diamonds of the Realm Online Slot Review

Many online slots developers find inspiration in medieval times for the creation of their titles. And although quite unusual for Play'n GO, which usually creates branded slots or slots with unique themes, the developer is launching a new slot inspired by King Arthur.

Named Diamonds of the Realm, the new slot arrives with 20 paylines across a standard 5x3 grid. As you would expect from a Play’n GO slot, this new arrival is a high variance title packed with Multipliers and progressive Free Spins, allowing for some massive payouts. As you go through our Diamonds of the Realm review, you’ll learn how to get your hands on those payouts yourself.

How to Play Diamonds of the Realm Slot

It should come as no surprise to you that Diamonds of the Realm is a slot playable across all devices, and specially optimized for mobile play, considering it was designed by Play'n GO. Whether you want to play it outside or at home, at the office, it will play seamlessly on any device.

As you load it, you will see Camelot in the background, the grid at the centre of the screen and all of the control buttons below it, as in most Play’n GO titles. First, you’ll see the Play and Autoplay buttons, going from right to left. Then, the Bet display will follow. The bet configuration field is next, where you could increase the stakes from 0.10 to up to 100 credits. Next, you’ll see the Balance display, followed by the last button, which actually takes you to the paytable.

Clicking or tapping on the “i” button, you’ll meet King Arthur, Queen Guinevere, and Modred and Morgan. These will be the high-pays, giving you up to 100x the stake, while the low-pays will be the playing card Royals, portrayed in medieval-style. The Scatters, of course, as implied by the title, would be the Diamond symbols, but expect to see Wilds, as well, delivering the top payout, just like the high-pay symbols for their respective 5-of-a-kind combos.

Diamonds of the Realm Features and Free Spins

The star feature in the slot is the Win Multiplier feature. This feature allows for Multipliers to appear on the reels during the base game. At random, one of those Multipliers will be chosen, multiplying any win you make during that spin by 100x, 10x, 5x or 2x.

Triggering the Diamonds of the Realm bonus game would be a rather simple task. Land at least 3 Scatters and you’ll get 5 Free Spins. During the bonus feature, the Multiplier from the base game will be always active, with its value starting at 2x.

Continue collecting Scatters during the bonus game, because by getting enough of them, you will move forward through the 3 progressive Free Spins levels. With 6 Scatters, you get the Multiplier to increase to 5x, and you get 5 more Free Spins. With 12 Scatters, the Multiplier increases to 10x and you get 5 extra Free Spins. And, with 18 Scatters, the Multiplier increases to 100x and you get 5 Free Spins!

The slot Diamonds of the Realm arrives with an RTP of 96.23%.

Sure, why not? The slot has been designed by the developer whose name is Play'n GO, a developer that has always been creating the best, most mobile-compatible slots of all times, HTML5 titles, playable across all tablets and smartphones.

There’s no exact guideline as to how to win on Diamonds of the Realm slot. You just need to place your bets, hope for the biggest Multipliers to land and trigger the bonus game.

Betting the max stake improves your chances of triggering the bonus game, and during the bonus game, the best prizes can be won. So, the decision is ultimately yours, but it won’t be wrong to place the max bet at least half of your playing time.

The minimum bet you can place on Diamonds of the Realm slot is 0.10 credits.

Diamonds of the Realm is a popular title, one, because it was developed by the renowned developer Play'n GO, two, because it is based on a medieval story about King Arthur, and three because it arrives with a huge payout potential.

Yes. The developer itself has stated that the slot would be a high variance one, 10 out 10, as a matter of fact.

Yes. You trigger the Free Spins as soon as you land at least three Scatter symbols. You get 5 Free Spins, but the bonus round is a progressive one, meaning you could additionally be getting 5 extra Free Spins with each new level you achieve.

No, not really. Once you reach the last level, the Scatters get removed from the reels, therefore, you cannot win any additional Free Spins.

The best Diamonds of the Realm for you may not be the best for someone else. Therefore, we cannot favour one casino over another. We can, however, advise you to go through our lists of thoroughly reviewed Play’n GO-powered online casinos that you can explore, to find the best one for you to join.
