Diamond Supernova 20 Slot Review
Diamond Supernova 20 is five reels of cut diamonds, 7s, bells and royals, with three coloured stars hanging over the top of the screen from the first spin to the last. Everything else has been left off the stage. It’s a sparse build, and deliberately so: every part of the game points up at that ladder of star prizes.
It comes from Push Gaming, a studio better known for big-variance fare like Razor Shark and Jammin’ Jars than for anything this gentle. This one runs on a 5×4 grid with 20 paylines and low volatility, and it puts every ounce of ambition into that single ladder of scatter prizes. Sit down with it and the stars are already waiting.
How Diamond Supernova 20 Pays
Wins are line-based across the 20 paylines, and the symbol set splits into two halves. The diamonds carry the real money, the 7s, bells and royals carry the small change. Line wins are multiples of the total bet, which keeps the arithmetic honest.
The paytable runs in tiers, and every symbol in it pays for three, four or five of a kind. The Red Diamond is the top payer and the only symbol with a two-of-a-kind payout:
- Red Diamond – 0.2x for two, 2.5x for three, 10x for four, 50x for five
- Blue Diamond – 1.5x for three, 6x for four, 30x for five
- White Diamond – 1x for three, 4x for four, 20x for five
- 7 and Bell – 0.5x for three, 2x for four, 10x for five
- A, K, Q and J – 0.2x for three, 1x for four, 5x for five
The structure of that list tells you how the game is balanced. The three diamonds sit in their own band at the top, the 7 and Bell occupy a middle tier on their own, and the four royals share a single row of identical values. Any royal is worth exactly as much as any other.
That shared royal row is worth a second look. Five Aces pays the same 5x as five Jacks, so there’s no reason to root for one over another, and a full royal line at the top of the grid pays no more than a single mixed scatter set. The royals exist to keep the reels busy.
The Red Diamond’s two-of-a-kind payout is the only one of its kind, and it’s a small thing with a real effect: the top symbol starts paying on the first two reels, before a line has even formed. No other symbol does that, so an early red pair is always live.
There’s no wild symbol in this game. Substitution isn’t part of the design, which tells you where the work went: everything outside the line wins lives in the scatter system.
Scatter Symbols and the Prize Ladder
The scatters are the feature, and there are three of them, coloured blue, red and gold. They land exclusively on reels 1, 3 and 5, which means every scatter that appears is either building towards a prize or paying one out.
The choice of those three reels matters. Reels 2 and 4 never carry a scatter, so a spin resolves the whole question in three places: one on the left, one in the middle, one on the right. Whatever sits between them is line-win business only.
The ladder they form hangs above the reels throughout play, spelling out all four prizes at whatever stake is set. Matching three of a kind on those three reels grants that colour’s prize:
- 3 Blue Scatters – 25x the bet
- 3 Red Scatters – 100x the bet
- 3 Gold Scatters – 1,000x the bet
The gold tier is the one that changes a session. At 1,000x the bet it towers over everything the paytable can produce, where even five Red Diamonds tops out at 50x. One lucky trio of gold stars is worth twenty full lines of the best-paying symbol.
The blue tier is the quieter comparison. Three blue stars pay 25x, which already beats a five-symbol line of the White Diamond, and does it with symbols that only need to land on three named reels rather than forming a line at all. Even the floor of the ladder out-pays most of the grid.
The steps between tiers are steep in a way the flat structure of the paytable isn’t. Blue to red is a fourfold jump, and red to gold is tenfold again. Landing three of any single colour is the whole event this game is built around.
The Mixed Scatter Prize
Matching three of a kind isn’t the only way the scatters pay. A mixed set, one blue, one red and one gold for instance, or two of one colour and a stray, awards a Mixed Scatter prize of 5x the bet.
It’s a small consolation prize, but it means every scatter that lands on those reels is worth something. Partial credit softens the miss, and it takes the edge off near-misses that would otherwise pay nothing at all.
Because the mixed prize is flat, the difference between two blues and a gold versus three blues is the difference between 5x and 25x, decided by a single symbol. The mixed tier exists for the spins that almost got there, and it pays the same whether the stray is a blue or a gold.
Our Honest Verdict
Overall Rating: 7/10
This is a slow-burn game dressed in diamonds. The line wins arrive small and often, and the one reason to choose it over a hundred other classic-styled slots sits above the reels: three gold stars pay 1,000x, and that’s a number worth waiting for in a game this calm.
The flat mixed prize is the smartest thing here. It means a scatter is never wasted, and every near-miss still hands back 5x, which keeps a low-variance session from ever feeling dead. The downside is everything between those moments: no wild, no free spins, nothing to do but watch the middle reels fill time.
It’s a good fit for players who enjoy long, steady sessions and don’t need a feature every thirty seconds, and it’s a curious, likeable detour for anyone who followed Push Gaming here from Razor Shark or Jammin’ Jars. The diamonds do the small work. The gold stars do the rest.
