Sunstrike Supernova Slot Review
A purple nebula glows behind the reels of Sunstrike Supernova, with cratered asteroids drifting beneath them and a chrome logo set in a ring of blue light like an eclipse. The paint job, though, is doing more work than the paytable underneath it: this is a game that pays crumbs for its regular symbols and keeps nearly all its money in one place, the multiplier collector behind the free spins. It’s built by TrueLab Games on a 6×5 grid, pays from eight matching symbols anywhere, and returns 95.62% over the long run.
The build sits in the same family as Crazy Mix and Siren Song from the same studio, though the cosmic presentation is a step up from either. Whether the bonus round earns the patience the base game demands is what everything here comes down to.
Base Game & Features
There are no paylines. Sunstrike Supernova uses scatter pays, so symbols count wherever they land: get eight or more matching symbols anywhere on the six reels and the game pays out. Wins don’t need to line up, and positions don’t matter.
Every win triggers a cascade. The winning symbols vanish, new ones fall into the gaps, and any new combinations formed by the drop pay again. One spin can chain several wins this way, and the reels keep tumbling until no new match forms.
On a 6×5 grid that’s thirty positions of material to work with, so a single drop can clear most of a column and refill it twice over. The game shows the full grid before the first cascade settles, then the columns empty and refill in stages. Each stage of a chain is a fresh chance at another eight-symbol cluster.
The size of the cluster sets the size of the pay. For the lower-value symbols the ladder runs in three steps, from eight symbols up to twelve or more. A nine-symbol cluster of the same symbol pays no more than eight, and the jump from eleven to twelve is where the values multiply hard.
The Symbols
There are nine regular symbols, split between glossy crystals and cut diamonds. The top five pay only at the top cluster size, while the smaller diamonds pay across three tiers. All values are multiples of the total bet:
- Orange crystal – 50 × Bet for 12+ symbols
- Purple crystal – 25 × Bet for 12+ symbols
- Blue crystal – 15 × Bet for 12+ symbols
- Orange diamond – 12 × Bet for 12+ symbols
- Pink diamond – 10 × Bet for 12+ symbols
- Purple diamond (triangle) – 0.8 × Bet for 8-9, 1.2 × Bet for 10-11, 8 × Bet for 12+
- Green diamond – 0.5 × Bet for 8-9, 1 × Bet for 10-11, 5 × Bet for 12+
- Light blue diamond – 0.4 × Bet for 8-9, 0.9 × Bet for 10-11, 4 × Bet for 12+
- Blue triangle – 0.25 × Bet for 8-9, 0.75 × Bet for 10-11, 2 × Bet for 12+
The ceiling on a single cluster is modest, then. Fifty times the bet for a full screen of the best symbol isn’t a number that turns heads, and the smaller diamonds pay fractions of the stake at the bottom tier. Cascades are what give a spin its reach.
The Scatter is the symbol that matters most. Four, five or six of them anywhere pay 3 ×, 5 × and 100 × the bet respectively, on top of what they trigger.
The shape of that ladder is worth a pause. Five Scatters pay barely more than four, but the sixth is worth twenty times the fifth. Landing that sixth symbol is the rare event the whole paytable leans around, and it pays out whether or not you go on to win anything in the round that follows.
Sunstrike Supernova Free Spins & Multipliers
Free Spins
Land four or more Scatters anywhere on the reels and the game awards 15 free spins. The triggering Scatters pay their instant award on the way in, and then the bonus round takes over.
The round runs on the same scatter-pays grid and the same cascades as the base game, with one addition: the total multiplier collector. Everything you already know about how wins form still applies. What changes is what each win is worth.
The Total Multiplier Collector
Multiplier symbols land during free spins in three tiers: ×2 to ×9, ×10 to ×90, and ×100 or more. The collector keeps a running total across the round rather than applying each multiplier to a single win, so the value builds the deeper the round goes.
A ×4 that lands on the first spin is still working for you on the fifteenth, and each new multiplier adds to a sum the whole round shares. Nothing resets between spins.
That’s the design choice that shapes everything else. A long run of cascades late in the session is where the money lives in this game, because every multiplier that landed earlier is still sitting in the total when the big cluster finally forms.
Bonus Bet
The Bonus Bet doubles the chance of entering free spins, at an extra cost of 25% of the current bet on every spin while it’s active. It’s a straightforward ante rather than a separate mode: the reels play the same, the odds of triggering improve, and the stake goes up to pay for it.
Switch it on when you want more bonus attempts per session, off when you don’t. There’s no third state and no other effect on how the game plays.
Buy Bonus
There’s also a Buy Bonus, which guarantees at least four Scatters land and the free spins round begins. The buy runs at 95.70% RTP, a touch above the standard game’s 95.62%. The price scales with the stake, and it’s the fastest route to the multiplier collector.
One thing to hold onto before buying: a bought trigger guarantees the four-Scatter award of 3 × the bet, not the five or six-symbol pays above it. The purchase buys the round, and the round’s value still depends entirely on what the collector gathers.
Our Honest Verdict
Overall Rating: 6.3/10
Playing Sunstrike Supernova is mostly waiting in a very beautiful waiting room. You spin, the crystals tumble, the nebula glows, and most of what happens amounts to very little. The reason to sit through that is the free spins, and specifically the collector: because nothing resets between spins, a round that keeps landing multipliers grows a momentum the base game never touches. That slow accumulation is the best thing here.
The worst thing is what you’re paid while you wait. Fifty times the bet for a full screen of the top symbol is poor for this style of game, and the smaller diamonds barely return the stake, so the base game leans entirely on the bonus round to justify itself.
It’s for the patient kind of scatter-pays player who enjoys a long build and treats the artwork as part of the entertainment. Anyone chasing big base-game hits will find the space between bonuses long and dimly lit.
