Diamonds Power XXL Hold and Win Slot Review
An oversized yellow diamond glows above the reels like a lamp, orange lightning forks crackle down the right-hand side of the frame, and a heap of raw white diamonds spills across the floor of a deep red vault. That’s Diamonds Power XXL Hold and Win, and it isn’t joking about the waiting: the base game barely pays at all, because every scrap of value is funnelled towards one settlement at the end of the Bonus Game.
Playson has built it on a 3×5 grid with 15 fixed paylines and a jackpot ladder topped by a Grand worth 1,000x. The setting is pure casino gloss: glossy 3D renders, heavy gold and chrome, high-saturation neon, no characters and no place, just the vault. Players who know 3 Pots Riches Extra: Hold & Win or Thunder Coins XXL: Booster Cells will recognise the family immediately, and Golden Penny x1000: Super Wheel sits in the same bracket.
Base Game & Features
The layout is unusual enough to deserve a sentence. Five reels are in play, but the visible arrangement shows three columns of paying symbols, with the centre column set apart by its own frame. It reads like a classic three-reeler that has been stretched at the edges.
Paylines are fixed at 15, and there’s no way to trim them for a smaller stake. Lines pay in succession from left to right, and only the highest combination on each line counts, so a stacked line doesn’t double up.
The reel set is pure retro: bells, BARs, 777s and suit symbols spin alongside the diamonds. Diamond symbols are the exception to the standard pays, because each one lands carrying its own displayed cash value, ready for the collection mechanic to sweep up.
The paytable is short and very top-heavy. Three of a kind is the only tier quoted, so there’s no escalation to four or five matching symbols anywhere in the game. The values step down steeply:
- Dice – 8x for three of a kind
- BAR – 4x for three of a kind
- Gems (Heart, Spade, Diamond, Green) – 1x for three of a kind
- Clubs – 0.5x for three of a kind
That’s the whole ladder. One symbol pays meaningfully, two pay pocket change, and the bottom rung returns half your stake for a full line. A full screen of Dice is the best the standard pays can manage, and even that is a modest 8x.
Wins shown in the demo run sat between 0.50 and 2.00. That tells you where the real money is meant to come from: the features.
Diamonds Power XXL Hold and Win Bonus Features
The Diamonds Power Feature
The headline mechanic is the collection system. A Power Bonus Symbol landing in combination with any Bonus Symbol triggers the Diamonds Power Feature.
What it does is gather. Every Bonus Symbol currently on the screen has its value collected, and that sweep includes the four jackpot plaques: Mini, Minor, Major and Grand all go into the pot when the feature fires. It’s the engine the rest of the game is built around.
The order of events matters for understanding the whole game. Bonus Symbols land carrying values, the Power Bonus Symbol combines with them to sweep everything into the pot, and the pot then waits for the Bonus Game to pay it out. The base game is really just the gathering phase of that cycle.
The Bonus Game
The Bonus Game is where the collected values are cashed out. When it ends, the values accumulated in all Power Bonus symbols are added to the Total Win, so everything the Diamonds Power Feature gathered during play pays out in one settlement rather than drip-feeding wins.
Jackpots can drop mid-round too. The random appearance of Bonus symbols during the Bonus Game triggers the corresponding jackpot, which keeps the round alive even when the reels aren’t building anything new. The four tiers step as follows:
- Grand Jackpot – x1000
- Major Jackpot – x100
- Minor Jackpot – x30
- Mini Jackpot – x15
It’s a steep ladder. The Grand sits ten times above the Major, and the Major sits more than three times above the Minor, so the format rewards the long shot rather than the steady climb. For a game built around collecting values, that top-heaviness is the whole design.
Diamond values on the reels during play ranged from 1.00 up to 5.00. The individual values are modest, which is why the collection matters more than any single line win. A screen full of them, plus a jackpot sweep, is where a strong round gets its total from.
Because the diamonds carry their own cash figures rather than paytable multiples, they sidestep the standard ladder entirely. A 5.00 diamond in view is worth exactly that, no matter which line it sits on or what surrounds it. The collection mechanic is what turns that into a meaningful total.
Bonus Buy
A Bonus button sits in the bottom-left corner of the base game screen, so the shortcut to the feature round is there for players who want it. No purchase prices are published for the demo build, so treat the button as an option rather than a recommendation until the live menu states its cost.
Our Honest Verdict
Overall Rating: 6.2/10
Playing this is mostly gathering. You watch diamonds land with numbers attached, you watch the pot grow, and you wait, because the vault doesn’t open until the Bonus Game closes. That’s the one reason to pick it: everything a session earned lands in a single payout, and a jackpot can land on top mid-round.
The best thing here is that settlement. One clean number at the end beats a dozen fiddly small pays, and the 1,000x Grand gives the wait a real destination. The weakness is the base game, which pays almost nothing while you’re in it, and a paytable where three of the four symbols may as well not exist. The vault dressing is handsome enough, but it’s a look you’ve seen before, and it does no work.
It’s for players who enjoy a long quiet build and one big finish, and who already like Playson’s hold-and-win format. Anyone who wants regular action spin by spin won’t get it here; the diamonds stay locked up until the end, and that’s the whole appeal.
