Bright red curtains and purple walls surround the reels, and a gilded frame adds to the regal style. It comes from Ainsworth, a popular Australian developer with hits such as Sheer Magic and Mustang Money in their range.

Most Ainsworth games use a similar style of graphics, and the Royal Diamonds slot machine is no exception. That means colorful, detailed high-value symbols, with standard playing card icons creating lower value combinations.

Alongside the precious jewels, the theme of royalty and wealth includes a horse-drawn carriage and a second diamond set in a cross. We’re guessing from the Union Jack pattern of the ring that the Royal Diamonds online slot is based on the British monarchy. Unfortunately, there is no sign of the Queen, Prince of Wales, or even Meghan Markle waving at us from the reels though!

You can stake as little as 0.04 on each of the 25 paylines, for an overall bet of 1.00 per spin. Max bets top out at 20.00 and you win by matching at least three symbols across a line from the left side. The controls are user-friendly and include Autoplay and Fastplay options.

We would class this as a medium variance game, and it has a good average RTP of 96.63%.

The paylines table shows you how many times your total stake you will win from each symbol –

In addition, the diamond scatter symbol pays 2x, 20x, and 100x your stake when landing in any three, four, or five places.

The diamond within a cross is the wild symbol of the Royal Diamonds slot machine. It’s not worth anything on its own but it is still very useful in completing combinations by substituting all except the scatter symbol.

The diamond scatter symbol unlocks a free games feature when seen in three or more places at once. You have five free spin options, and the round begins when you pick from one of them. You could choose 20 free games, with any wins created with the help of the wild symbol doubled value.

At the other extreme, you can choose just five free spins, but if the wild completes any combinations, the win is multiplied by 10x. Average returns are the same in each, so which one you choose won’t make a whole lot of difference over many rounds. We usually go for the middle option, which in the case of the Royal Diamonds online slot, means 12 free spins, with a 4x multiplier.

A big red ruby symbol is active during the free spins. It’s worth 0.8x your stake when seen on just reels one and two across a line, and 4x when it fills a payline.

The Mini, Minor, Maxi, and Major non-progressive jackpot values appear above the reels. Land five matching playing card symbols, without a wild, but with the Quad Shot framing one of them, to win the Maxi prize.

The Mini jackpot is yours if a wild is part of the combination. You win Minor and Major jackpots when picture symbols and the Quad Shot appear in the same way.

The Unlikely Royals slot from ReelNRG takes a much more humorous approach to the subject. Cartoonish characters join playing card symbols over five reels and 40 paylines. Features include low-value symbol replacements, mini-slots side games, and a fun art auction bonus round.

Neon-effect guardsmen, London Underground logos, and 7s decorated with Union Jacks appear in the Royal Wins slot from Booming Games. It’s a five-reel, 20-line game that comes with free spins and the option to gamble wins for some huge prizes.

Is the Royal Diamonds slot machine really the jewel in Aristocrat’s crown? That depends on whether you like sparkly objects or not. The features will appeal to anyone though, so it’s a game worth checking out!
