Diamonds of the Realm: Slot Overview

Developer Play’n GO return to the Arthurian well with their medieval-themed slot Diamonds of the Realm. This isn’t merely a successor to the earlier titles The Sword and the Grail and The Green Knight; it’s essentially the same game, just with a handful of statistical tweaks. By now, it feels like Arthur and company have appeared in countless Play’n GO releases. Luckily, the studio tends to do this theme well, and even when the ideas aren’t blazing with originality, the end result is usually reliably fun.

A short intro on the game sheet sets the scene. In this version of the legend, Camelot has been plunged into darkness by Morgan and Mordred. Driven by revenge (or whatever fuels them), the pair have stolen the Diamonds of the Realm. Your task is to reclaim them during free spins, where strong rewards can be earned if you do your duty.

Whether the diamonds are magical or simply valuable, chasing them down is a perfectly good reason to ride out with Arthur and the knights again. Play’n GO clearly has a fondness for this style of slot, and their catalogue has plenty of similar entries at this point. Diamonds of the Realm is among the darker-looking ones, which fits the whole “shadow over Camelot” angle. Camelot looms in the background behind a 5-reel, 20 payline layout, and above the reels sits the multiplier trail, ready to trigger in the base game and then on every single free spin.

On the maths side, a few things have shifted. The theoretical return has dropped a touch, coming in at 96.23% in the default setup. The volatility stays extremely high, rated a full 10 out of 10, so Diamonds of the Realm is just as unpredictable as its predecessor ‘Grail’. As before, bets range from 10 p/c to $/€100 per spin, so that part remains unchanged.

As you fight to restore the realm, standard wins land when three to five matching symbols connect from the left side. The low pays are coins marked J, Q, K, A, and T, while Mordred, Morgan, Queen Guinevere, and King Arthur make up the 4 premium symbols. Landing five premium symbols on a payline returns 7.5 to 100 times your stake. A wild symbol also appears on any reel and substitutes for all symbols except diamond scatters. Like the King, wilds can pay up to 100x the stake for a five-of-a-kind line.

Diamonds of the Realm: Slot Features

Diamonds of the Realm includes two tightly connected features: one that spices up the base game and another that delivers a set of triggered free spins. During the main game, the Win Multiplier feature can activate at any time. When it hits, multiplier values of x2, x5, x10, or x100 appear above the reels. If you land a win on that spin, the payout is boosted by the randomly chosen multiplier.

To trigger free spins, you must land at least 3 diamond scatters on the reels. This awards 5 free spins with the multiplier always active, meaning every win in the bonus starts out with a x2 multiplier applied.

Diamond scatters are still key symbols during free spins and are collected whenever they appear. Collecting enough advances you through 3 more levels, as follows:

• Level 2 – collecting 6 diamonds awards +5 free spins and increases the win multiplier to x5.
• Level 3– collecting 12 diamonds awards +5 free spins and increases the win multiplier to x10.
• Level 4 – collecting 18 diamonds awards +5 free spins and increases the win multiplier to x100. Once reaching level 4, diamonds are removed from the reels, so additional free spins cannot be won.

Diamonds of the Realm: Slot Verdict

If The Sword and the Grail was your kind of game, Diamonds of the Realm should be an easy sell too, since it’s effectively the same experience but with higher potential. And if you’ve enjoyed any of Play’n GO’s Arthurian-themed slots, it’s worth giving Diamonds of the Realm a go as well. They share a familiar appeal, built around big multipliers across the game. It can feel a bit by-the-numbers, but it’s a strong formula: great presentation, plenty of moody atmosphere, and gameplay that’s consistently solid.

That gameplay revolves around a sizeable bonus that echoes 300 Shields, with the occasional base-game multiplier helping to keep things lively. Play’n GO are known for dropping random multipliers into the main game, though they don’t often reach x100—something that can make a huge difference if it lands at the right moment. Free spins are every bit as punchy here as they were in The Sword and the Grail. It begins with a brief run of five spins, then it’s all about landing diamond scatters to climb through the levels toward the coveted x100 stage.

The key distinction from the previous game is that the payoff for successfully protecting the realm—recovering the diamonds, or however you want to frame it—has been doubled compared to the two earlier titles, topping out at 20,000 times the bet. The odds are also marginally improved, though at around 1 in 90 million spins, it’s still not something you should expect to see anytime soon.

It’s fair to say Diamonds of the Realm isn’t strictly necessary, since it doesn’t add much that the original didn’t already do. Still, anyone craving more polished, high-volatility, Arthur-led action probably won’t mind—especially with the bigger maximum win potential included in the deal.
