Diamonds of the Realm Slot RTP, Details & Wager Limits

Reels/Paylines: 5 reels + 20 paylines

Stakes Range: 10p to £100 per spin

RTP: 96.23%

Max Win: 20,000 x stake per spin

The Diamonds of the Realm slot takes place on 5 reels, 3 rows and 20 fixed paylines. Winning combinations are simply created by landing 3 or more matching symbols across a payline, from left to right and beginning from the first reel.

This slice of Arthurian legend can be played from 10p to £100 a spin. You will see 5 available bets below the reels which you can adjust by clicking on the plus and minus buttons. In some countries, there’s a Fast Play mode (click on the Lightning Bolt icon) as well as an Autoplay function.

The Diamonds of the Realm RTP is 96.23% which is slightly above the slots average. What isn’t the norm is the variance which is sky high. It’s classed as very high and 10/10 by provider Play ‘n GO.

Big wins are also possible with max payouts of 20,000 x your total stake per spin. The probability of winning this is 1 in 90,909,091 spins (nearly 91 million). This figure is lower than a lot of high variance slots.

Theme – Audio & Design Features – join King Arthur and Queen Guinevere on a quest of perseverance  

Theme: Arthurian Legend

High Value Symbol: King Arthur

Compatibility: Mobile, Tablet, Desktop


With an Arthurian legend theme, the Diamonds of the Realm slot sees you go on a quest of perseverance alongside King Arthur and Queen Guinevere. With a medieval theme, the backstory is that Morgan and Mordred stolen the diamonds (of the realm) so you go on a quest to get them back.

Set amidst Camelot Castle, it’s graphically quite dark which sets the tone nicely. Symbols on the reels include low value T, A, K, Q and J coins. You will also find the game’s main characters including Mordred (Arthur’s traitorous nephew), Morgan (Arthur’s half-sister), Queen Guinevere (Arthur’s wife) and King Arthur himself. King Arthur is the highest paying symbol giving you 2.5, 5 or 100 x your total stake for 3, 4 or 5 in combination.

There is also a wild symbol which substitutes for all symbols bar the diamond scatter. Like King Arthur, it pays up to 100 x your total stake for 5 across a payline. Here’s list of payouts/info for each symbol:

Diamonds of the Realm has been produced with HTML5 technology. This means it’s optimised and available to play on mobile, tablet and desktop devices. The 5×3 reel layout works well on smaller handheld devices.

Diamonds of the Realm Bonus Features

Diamonds of the Realm comes with just 2 bonus features. Offering win multipliers up to 100x and free spins, they can combine to devastating effect in the Free Spins feature if you collect enough diamond scatters.

Win Multiplier feature

Randomly on any spin, the Win Multiplier can trigger. You will see the Win Multiplier values of 2x, 5x, 10x and 100x appear above the reels. If you get a win on this spin, the active Win Multiplier above the reels will apply.

Free Spins feature


To play the Free Spins feature, you need to land 3 or more Diamond scatters on any reels. The Win Multiplier feature is always active meaning a win of between 2x and 100x on each free spin.

You will begin the feature with 5 free spins. To increase your tally, collect Diamond scatters. This will give you extra free spins and increase the Win Multiplier level. The Diamond scatters that triggered the free spins will count towards the numbers shown below:

Diamonds Collected Extra Free Spins Win Multiplier Level
6 in total +5 free spins (total of 10) 5x for remaining free spins
12 in total +5 free spins (total of 15) 10x for remaining free spins
18 in total +5 free spins (total of 20) 100x for remaining free spins

Once you’ve collected 18 Diamond scatters, you will get more free spins to take your tally to 20 in total. With a 100x multiplier on remaining free spins, diamonds won’t appear on the reels meaning additional free spins cannot be won.

RTP (96.23%)

Max Win (20,000 x)


The Diamonds of the Realm slot is quite a simple game with win multipliers and free spins core to all the action. However, the win multiplier can reach 100x on a base game and free spin.

The biggest wins will come in the free spins if you manage to collect enough diamond scatters. It has a lot of similarities to The Green Knight (also by Play ‘n GO) as it shares the same Arthurian legend theme and multipliers (wild) up to 100x. The main difference is that this game offers 20,000 x stake max wins as opposed to 10,000 x in The Green Knight.

The Free Spins feature in Diamonds of the Realm reminds me of the Battle Feature Free Games feature in  300 Shields (by NextGen Gaming) where you collect shields to win free spins (5 each time) and increase the multiplier (up to 300x).

In summary, Diamonds of the Realm is a simple yet potentially rewarding slot from the reputable provider. It also follows a long list of games with this theme. I recommend you try Lord Merlin and the Lady of the Lake which offers expanding symbols in the free spins and 10,000 x stake max wins.

  • Fantastic graphics + soundtrack
  • Big win potential - 20,000 x stake per spin
  • 100x multipliers in base game/free spins
  • Very volatile
