Royal Diamonds Game Features

This online casino game has three features to watch out for:

Royal Diamonds Wild Symbol Feature

Crest wilds substitute for almost everything except diamond scatters and the Quad Shot Bonus icon. They don’t carry their own payout values, but they’re essential for hitting the Quad Shot bonus prizes. 

Royal Diamonds Free Games Feature

Diamond scatters pay for three or more in any position on the grid. The Free Games Feature triggers when 3 or more diamond scatters land anywhere. When it hits, players choose from five options, each mixing spin counts with multiplier values:

  • 20 Free Games with a 2x multiplier.
  • 15 Free Games with a 3x multiplier.
  • 12 Free Games with a 4x multiplier.
  • 10 Free Games with a 5x multiplier.
  • 5 Free Games with a 10x multiplier.

During Free Games, wilds appear only on the middle three reels, and any additional scatter trigger repeats the same option you originally selected. Ruby symbols appear exclusively within the feature, adding a bit of variety to the upgraded reel set.

Royal Diamonds Quad Shot Bonus Feature

The Quad Shot Bonus weaves in a four-tier fixed jackpot system tied to very specific types of five-symbol wins. Quad Shot overlays appear on the last reel only. The Quad Shot system essentially turns regular line hits into potential jackpot moments when the right combo appears in an overlay. 

If a winning five-of-a-kind line lands with a Quad Shot Bonus overlay, one of these rewards triggers:

  • Major Bonus: Five-of-a-kind royal symbol with a Quad Shot Bonus overlay with no Wilds.
  • Minor Bonus: Five-of-a-kind royal symbol in a Quad Shot Bonus overlay with at least one Wild.
  • Maxi Bonus: Five-of-a-kind playing card symbol Quad Shot Bonus overlay with no Wilds.
  • Mini Bonus: Five-of-a-kind playing card symbol Quad Shot Bonus overlay with at least one Wild

Royal Diamonds Slot Bonuses and Jackpots

Royal Diamonds uses four fixed jackpots tied to the Quad Shot Bonus mechanic. Each jackpot pays out a set amount of credits:

  • Major Bonus: 10,000 credits
  • Maxi Bonus: 1,250 credits
  • Minor Bonus: 200 credits
  • Mini Bonus: 50 credits

How To Win the Royal Diamonds Game

Royal Diamonds pays left to right for matching on adjacent reels across its 25 paylines, starting from the leftmost reel. Scatters are an exception and pay anywhere. Line up matching symbols, aim for full-reel stacks when possible, and keep an eye on combinations that can interact with Quad Shot overlays. If you’re wondering if it’s better to place a max bet for better payouts, a max wager doesn’t affect your odds of winning, just the total potential payout. Ultimately, a good slot game strategy is to wager carefully to make your slot bankroll go as far as possible. 

Royal Diamonds Game Graphics and Design

Royal Diamonds sticks to traditional slot presentations, with bold icons and a royal aesthetic that shines through in the deep purple hallway backdrop and golden framing around the reels. Symbol styling also includes various royal ornaments and artifacts like crowns, diamonds, and gemstones, while the soundtrack carries the mood with a cheerful flute-driven jingle.

Royal Diamonds Slot Symbols

The paytable splits symbols into two categories. Low-payers include playing card symbols 9, 10, and jack paying up to 2x, along with the queen, king, and ace (and the ruby symbol during free spins) paying up to 4x for full lines. Higher payers include a jeweled goblet, a ring, a sovereign’s orb, a royal carriage, and a crown, with max wins of 6x, 8x, 8x, 8x, and 12x, respectively. The Diamond scatter has a maximum payout of 100x.
