3 SuperPower Diamonds Slot Review
A wooden-rimmed prize wheel turns behind the reel window, its jackpot segments half-hidden by the grid, while three lightning-bolt tiles glow above the frame. Most slots keep their backdrop and their mechanics in separate rooms; 3 SuperPower Diamonds runs its three modifiers and five jackpot tiers off that very wheel, making the scenery the most functional part of the screen.
The game comes from 3 Oaks Gaming, and the reels underneath the wheel are deliberately ordinary: a 5×3 grid with 25 paylines, 7s, BARs and hearts, and no published RTP. Everything interesting has been pushed upward, onto the wheel and its ladder.
Diamonds, lightning and a wheel that never stops turning. It’s a glitzy setup, and the question is whether the mechanics underneath the chrome earn it.
Base Game & Features
The base game is a classic five-reel, three-row layout with 25 fixed paylines. Wins pay left to right, and only the highest combination on each line counts. Symbols include 7s, BARs and hearts, alongside the three coloured diamond modifiers that give the game its name.
Because every line is fixed, a spin always covers all 25 of them, and there’s no way to play a reduced set. That keeps the stake even across the board but also means the smaller symbol wins arrive one at a time rather than stacking from a handful of active lines. For a game built around chasing a ladder, the flat structure keeps things simple.
Base wins tend to be modest. At a 1.00 stake, observed rounds returned values from 0.2x up to 14x the bet, with the bigger hits coming from 7 combinations. That 14x return was the stand-out result.
The observed results give a picture of how the pays are spread:
- 14x – 7s, the best result seen
- 4.6x – BAR symbols
- 4.2x – hearts and a BAR line
- 2.7x – 7 and BAR symbols
- 1.8x – a 7, BAR and Multi combination
- 0.2x – BAR symbols, the smallest return seen
The pattern is clear enough. Sevens sit at the top of the pays, BARs and hearts fill the middle, and the three diamonds are what turn an ordinary spin into something worth watching. The balance moved down and up across the session, consistent with that 1.00 stake throughout.
The Three SuperPower Diamonds
Three special diamond symbols can land on the reels, each one tied to a lightning-bolt tile mounted above the grid. One tile glows green, one red, one black, each captioned with its modifier’s name. They’re the game’s signature, and each does something different.
- Multi – a green diamond that can trigger the Bonus Game with the Multi Hold and Win feature, dropping two to five multipliers of x2 to x5 onto the symbols on the reels
- Mystery – a red diamond that can trigger the Bonus Game with the Mystery Hold and Win feature, turning into a Mini, Minor or Major jackpot or a value of 15x, 25x or 40x the bet
- Collect – a purple diamond that can trigger the Bonus Game with the Collect Hold and Win feature, gathering every value on the reels into a single symbol
Each diamond has a chance to trigger the Bonus Game on its own. That round is a hold-and-win: three respins, every new symbol sticks and resets the count to three, and it ends when the respins run out or all 15 positions are filled, at which point every value on the reels is added up and paid. Regular BONUS symbols are worth 1x to 8x the bet.
The three effects can also work together. When several diamonds land on one spin, the Bonus Game can start as a double or triple, with the features playing in the order Mystery, Multi, Collect. That order matters: a Collect at the end gathers values that Mystery and Multi have already raised.
Each diamond also has a matching segment on the prize wheel behind the reels, so the modifiers landing in the base game are the same ones the wheel dispenses. It ties the two halves of the screen together neatly.
3 SuperPower Diamonds Bonus Wheel & Jackpots
The wheel is the centrepiece. It sits behind the reel window for the whole session, and one spin of this Standard Wheel is awarded every time the Bonus Game is about to start. Its prizes are the three diamond features, a Diamond Boost that spreads an extra 3x to 7x the bet across the BONUS symbols, the Mini, Minor and Major jackpots, and Expand, which stretches the reels from 5×3 to 5×6 and adds a spin of the Super Wheel.
The Jackpot Ladder
Five fixed jackpots make up the ladder, stepping from the bottom up:
- Mini – 10x the bet
- Minor – 20x the bet
- Major – 50x the bet
- Grand – 1,000x the bet, for filling all 15 positions in the Bonus Game
- Royal – 10,000x the bet, for filling all 30 positions once the reels have expanded to 5×6
The jackpot segments appear in blue and purple lettering, with the Major, Minor and Mini slices visible behind the reels during ordinary play. The jackpots are fixed multiples of the bet rather than progressive, and they land and pay only in the Bonus Game.
Mini, Minor and Major arrive through the Mystery feature, the Standard Wheel or the Super Wheel, which awards one to three jackpots of the same kind. Grand and Royal can only be won by filling the board: all 15 positions on the 5×3 grid for the Grand, or all 30 once an Expand result has stretched the reels to 5×6 for the Royal.
Mostly hidden behind the reel window, the wheel reveals itself in slices. You’ll catch the blue and purple jackpot lettering on one spin, the modifier segments on the next, which keeps a static backdrop feeling alive without the game lifting a finger to animate it.
How the Wheel and the Diamonds Connect
The Multi, Mystery and Collect segments on the wheel mirror the three diamond symbols on the reels. Land a diamond and its effect fires; the wheel stands ready with the same trio of modifiers. It’s a single system expressed twice, once on the reels and once above them.
The maximum win is 10,000x the bet, the same figure as the Royal jackpot. If a round reaches it, the round ends at once and the maximum is paid.
Our Honest Verdict
Overall Rating: 6.3/10
Playing this is mostly watching the wheel. The reels hand out small, familiar 7s-and-BARs wins while the neon ladder behind them quietly builds, and that slow accumulation is the reason anybody sits down at this machine at all.
The best thing about it is the build into the Bonus Game: one diamond can start it, several can stack two or three features, and the wheel spin on the way in can stretch the reels towards the 10,000x Royal. The problem is the reels themselves. They’re the most generic set 3 Oaks could have chosen, and the base pays are thin enough that the long stretches between modifiers can feel like filler.
This is a game for jackpot hunters who enjoy a patient build and don’t mind plain reels carrying it. Anyone wanting varied base mechanics or big symbol pays will find more elsewhere. For players happy to let the chrome do the talking, the wheel keeps its promise.
