Diamond Supernova

Diamond Supernova takes the classic fruit-machine format into outer space, landing under the Push Gaming banner via its Reel Hot Games label. It's a 5-reel, 3-row slot available in four different payline configurations — 5, 10, 20 or 100 lines — so the exact structure you're playing can vary depending on which version is loaded, but the underlying formula stays the same throughout: traditional symbols, straightforward line wins, and payouts driven mainly by scatters.

Visually, it pairs a cosmic backdrop with old-school icons — diamonds, bells, lucky 7s and card royals — all presented in a clean, readable layout that keeps the focus on the numbers rather than elaborate animation. It's a polished bit of design work, but the theme itself is more of a backdrop than a driving force; this is a game about the mechanics of a classic slot rather than a story or a world to get immersed in.

There are no wilds, no free spins and no multipliers here — Diamond Supernova keeps its feature set deliberately minimal. The real payout engine is its trio of star scatters: land a blue, red or gold star on reels 1, 3 and 5 and you'll trigger a scatter payout worth 25x, 100x or a substantial 1,000x the stake depending on colour, while a mixed combination of different-coloured stars still pays out at 5x. Beyond that, it's pure line-win territory, with the paytable built around frequent small-to-moderate returns rather than dramatic spikes.

That structure lines up neatly with the Low volatility rating — Diamond Supernova is built to keep the reels ticking over with regular, modest wins rather than long droughts punctuated by huge multipliers. The 96.34% RTP is a solid, above-average figure that reinforces the sense of a slot designed for steady, relaxed play, and the 1,016x max win reflects a payout ceiling that's realistic rather than headline-grabbing — most of what you'll see in practice will be far smaller than that top figure. Stakes span 10p to £/€100 per spin, giving room to adjust across the different payline versions.

Diamond Supernova isn't trying to reinvent anything, and it knows it — this is a comfort-food slot for players who enjoy the rhythm of a classic format without needing constant surprises.
