Diamond Supernova 20: Chase Star Alignments on Push Gaming's 20-Line Diamond Grid

Matija Antic rated this game:

3.5 out of 5

Wait, did I just enter a slot or disco? It is Push Gaming's 20-payline version of the Diamond Supernova series after all. It greets you with a cool, although slightly misleading, background 90s-vibe beat, and on the technical side, 96.33% RTP with low volatility.

As shown at the top of the five-reel, three-row grid, the maximum prize you can get your hands on is 1,000x your bet, but only through aligning three Gold Star Scatters on reels one, three, and five. Three Red Stars pay x100, three Blue Stars x25, and any mixed combination of the three gives you x5.

My base game stayed at the lower edge, somewhere between 0.3x and 1.5x from royals, bells, and the occasional seven. Still, the grid sent its apologies through a couple of star combos.

The first one was a cocktail of all three colours, one gold, one red, one blue, landing on the right reels for a x5 return. And just when my balance crawled back to where it was before, three Blue Stars aligned and handed me 25x my bet.

I never reached the top two alignments from Gold or Red, so the big prizes stayed out of reach. But the low volatility base game kept feeding me enough to stay alive between those star moments.

For a slot with no Wild, no Free Spins, and no Bonus Round, Diamond Supernova 20 relies entirely on symbols and the star system to keep you spinning. As one of 4 edition in this series, this sequel sets a solid baseline. The mechanics are clean and easy to follow, and I am curious how the other payline versions perform.

PROS

Clean, no-clutter mechanics
Low volatility is ideal for this type of slot

CONS

No Wild or bonus features
Gold and Red Stars stayed hidden
