Purple Diamond Slot Review
The Royal Purple Heart is a 7.34-carat fancy vivid purple diamond, and as far as anyone can tell, it's one of the rarest colored diamonds 💎 on the planet.
It sits in a private collection somewhere, last valued at figures that would make a billionaire wince, and has never been put up for public auction. Most gemologists retire without ever seeing a purple diamond in person. 😳 They're that scarce.
Naturally, that kind of rarity attracts a very specific type of buyer... the sort who treats private jets 🛩️ like taxis and considers a Michelin star "a decent start." Not exactly relatable, but you've got to admire the audacity.
This is Purple Diamond slot from 3Oaks.
Gameplay
The setup is a classic fruit machine dressed up in nightclub lighting. A 5-reel, 3-row grid glows against a deep purple backdrop, and the symbols are exactly what you'd expect from a game wearing this much neon.
High-paying symbols are the 7 and Bell, followed by the Horseshoe and Bar. The low-paying kind are the card royals: A, K, Q, J, 10. The Wild substitutes for all symbols except the Bonus and Collect.
To the left are the four Jackpots, on full display: Mini (10x), Minor (20x), Major (75x), and Grand (1,000x).
The stats holding this whole thing together: 20 paylines, a 95.70% RTPRTP stands for “Return to Player.” The RTP describes the total bet amount that a game returns to players over millions of spins, and that figure is represented by a percentage. Table games, such as Roulette, typically have higher RTPs than many slots.
RTP needs to be considered in conjunction with a game’s volatility rate., medium/high volatility, a 2,172x max multiplier, and a $195,480 max win. JPY and AUD are not accepted.
Features
HOLD AND WIN
Landing 6 or more Bonus symbols (glowing blue circles carrying multiplier values), or a combination of Bonus and Collect symbols, triggers the Hold and WinThis feature plays out on a new screen. Typically, you get 3 re-spins (which could be re-triggered), and the triggering symbols usually stick to the position on which they land. Your objective is to land as many symbols as possible on the grid (you could land blank tiles, too). Bonus Game.
You’ll start off with 4 spins, which is one more than the genre standard, and only Bonus, Collect, Super Collect, and Jackpot symbols are in play during the round.

Collect
The Purple Diamond Collect symbol appears on rows 2 through 5. When it lands, it absorbs all Bonus symbols on the reel below it, gives you a +1 spin, fills the progress bar of the lowest locked row, and then converts into a Bonus symbol itself.
Super Collect
The Gold Diamond Super Collect only appears on the 6th row and is considerably more aggressive. It absorbs all Bonus symbols on the reel beneath it on every single spin until the Bonus Game ends, not just once.
It also awards +2 spins on arrival and is the only symbol through which the Grand Jackpot can appear.
ROWS UNLOCKING
Rows 4, 5, and 6 are locked at the start of the Bonus Game. Each row unlocks after 3 Collect symbols appear on the active reels. So, you need 3 Collect symbols to open row 4, another 3 for row 5, and another 3 for row 6.

More rows mean more positions for Bonus symbols to land, and reaching row 6 is the only path to the Super Collect and the Grand Jackpot.
JACKPOT FEATURE
Keep an eye out for Jackpot symbols:
- Mini - 10x
- Minor - 20x
- Major - 75x
- Grand - 1,000x
The Grand Jackpot is exclusive to the Super Collect symbol on row 6, meaning you need to unlock the full grid before it's even in play.
Performance
No hiccups, no drama. Everything loaded fast and ran clean across the board.
Max Win
Accepted bets run from $0.20 to $90.00. Hitting the 2,172x max multiplier on a $90 bet means you’ll walk away with the $195,480 max win.
Conclusion
Your time in the base game means spinning to rack up enough blue Bonus circles to cross that 6-symbol threshold and get the Hold and WinThis feature plays out on a new screen. Typically, you get 3 re-spins (which could be re-triggered), and the triggering symbols usually stick to the position on which they land. Your objective is to land as many symbols as possible on the grid (you could land blank tiles, too). rolling. The paytable wins are fine, but nothing in this game is going to move the needle without the Bonus Game getting involved.
Once you're in, the first few spins will tell you a lot, and landing Collect symbols early is the priority. Each one unlocks progress toward the locked rows, and until you're working with more than 3 rows, the bonus is pretty capped.
The real action only opens up when rows 4 and 5 come online, giving Bonus symbols more space to land and resetting your spin count.
You want to open up Row 6, though, because that’s where the whole thing changes. Getting there requires a lot of Collect symbols, and once it unlocks, the Super Collect becomes available.
That gold diamond sitting on the 6th row and absorbing the reel below it on every spin for the rest of the round is the closest this game gets to a proper snowball moment, and it's the only way the Grand Jackpot shows up. Without row 6, you're not touching it.
For patient players grinding it out, keep bets manageable, and don't expect a lot from base game returns. Wait for the Bonus to fire naturally and give yourself enough bankroll to see it through.
A bonus that opens up two locked rows is interesting, but one that opens all three is where you actually have a conversation about the max win.
Balanced players will want to look closely at those opening Collect symbol hits. If two or three land in the first couple of spins and rows are unlocking fast, that's a bonus worth riding. If the early spins go quiet, the ceiling on that round is limited regardless of what happens later.
High-risk players are relying on a very specific chain: unlock all six rows, land Super Collect on row 6, accumulate big multiplier Bonus symbols on the reels below it, and hold on long enough for the Grand Jackpot to appear.
That sequence needs a lot of things to fall into place, but it's the only route there.
