Starburst Galaxy (NetEnt) Slot Review & Demo

🗝️ Key Takeaways

• Line up 3 or more matching gems in a straight row or column anywhere on the 5x5 grid, and every win sets off an Avalanche.
• Watch a fresh Wild drop into the centre of each winning line as it clears, ready to build the next win.
• String five wins together to unlock a feature from the Feature Generator, and five features open Galaxy Star on a 7x7 grid.
• Land 3 Scatters for Mega Star, where a 2x2 Wild arrives and Scatter multipliers up to 25x stack up until the spin is over.
• Skip ahead through the Elevate menu, from a 3x Bonus Boost to a 500x Galaxy Star Bonanza with a random 2x to 75x multiplier.
• Expect Medium volatility, a 96.00% RTP on every route and a 17,288x top win.

Deep space stretches behind the grid in shades of violet and plum, scattered with sharp white starlight. A rose-pink planet curves up from the lower left, and a golden ringed world hangs half out of frame in the top right corner, close enough to feel the glow.

A deep synth pad hums underneath everything, and soft 80s-style arpeggios shimmer over the top, calm enough to drift along with during quiet spins. Gems land with a glassy tap, and a cleared win breaks with a resonant shatter that runs straight into the next drop.

This is Starburst Galaxy from NetEnt, the follow-up to one of the best-known slots ever made. The gems and the rainbow Wild are back, but the reels now cascade, wins reward you with features, and a full run of them blows the grid out to seven by seven.

🌌 A Jewel Box in Orbit

The reels have no frame at all. The gems float straight against the starfield in five neat columns, which makes the whole game look less like a cabinet and more like a tray of jewels drifting through space.

The Starburst Galaxy logo sits in the top left in chrome lettering tinted pink and violet, with a glowing orb burning behind it. Below it runs a row of five small purple spheres, the Feature Generator, and under those a gold-edged box marked X waits for the Multiplier Collect Meter to fill it.

The Elevate button is a glossy purple pill with gold lettering and an arrow shooting up through the middle. The spin button below the reels is a bright green disc, flanked by smaller purple buttons for quick spin and autoplay.

The gems will be familiar to anyone who played the original. The purple diamond and the blue square cut fill the lowest rung, followed by an orange hexagon, a green hexagon and a yellow trillion cut, each lit from inside so it glows against the dark.

Above them come the classic fruit machine icons, given a space-age polish. The red 7 sits inside a glassy blue sphere with an orbit ring around it, and the BAR is a gold coin circled by a ring of its own.

The Wild is the eight-pointed rainbow star with a pearl at its centre, and it can land as a single symbol, a 2x2 block or a 3x3 giant. The Scatter is a crackling orb of white and violet plasma, and some carry a multiplier stamped across the middle in gold.

💎 Straight Lines and Falling Gems

There are no paylines to follow. Matching gems pay whenever three or more of them form an unbroken row or column, wherever that happens on the grid, and only the best combination on any one line counts.

Every win starts an Avalanche. The winning gems vanish, everything above slides down into the gaps, fresh symbols fall in from the top, and the grid is checked again until nothing more connects.

The Wilds are what keep that chain going. When a winning line clears without a Wild in it, a new Wild is placed at its centre, or just left of centre on an even horizontal line and just above centre on an even vertical one.

When two winning lines cross, each gets its own Wild, unless their centres meet, in which case one Wild takes the shared spot. Wilds can take the place of any symbol bar the Scatter, and three, four or five in a line with nothing else to join pay the highest win available on the paytable.

📊 RTP and Volatility

Starburst Galaxy has a fixed RTP of 96.00%, and every Elevate option returns exactly the same, so there is no cheaper or dearer route in terms of return. Our explainer on what RTP actually measures shows why a matching figure across every mode is worth noting.

Volatility is Medium. About 24% of spins pay something, close to one in four, and the Avalanches keep most of those wins small while the features carry the bigger results.

What hit frequency means puts a figure like 24% into the context of a real session, and our volatility breakdown explains how a Medium rating balances the two. Bets run from €0.20 to €20, and the top win of 17,288x comes to €345,760 at the highest stake.

💰 Symbols and Payouts

Every figure below assumes a 1.00 stake, running from seven in a line down to three.

High Paying:

• BAR: 250.00 / 100.00 / 20.00 / 4.00 / 1.00.
• Red 7: 50.00 / 30.00 / 15.00 / 3.00 / 0.75.
• Yellow gem: 40.00 / 20.00 / 10.00 / 2.25 / 0.75.

Low Paying:

• Green gem: 30.00 / 10.00 / 5.00 / 1.50 / 0.50.
• Orange gem: 20.00 / 5.00 / 2.50 / 1.00 / 0.50.
• Blue gem: 10.00 / 4.00 / 2.00 / 0.50 / 0.25.
• Purple gem: 10.00 / 4.00 / 2.00 / 0.50 / 0.25.

Special Symbols:

• Wild (Starburst): Covers for any symbol apart from the Scatter, in sizes from one cell up to nine.
• Scatter (Plasma Orb): A set of three in one spin opens Mega Star, and some carry multipliers of 2x, 3x, 5x, 10x or 25x.

Lines of six and seven only become possible once the grid grows in Galaxy Star. That is where the BAR’s 250.00 for seven sits, five times its 50.00 neighbour on the red 7.

⚙️ The Feature Generator

In the main game, every win counts towards the Feature Generator, and every five wins in a row award one of five features, lit up one by one in the spheres under the logo:

• Destroy removes one or more random types of symbol from the reels.
• Random Wilds turns 3 to 9 paying symbols into Wilds.
• Expanding Wilds turns every Wild on the grid into a stack of three.
• Line Transform fills a row or a reel with one randomly chosen paying symbol.
• Upgrade turns one or more random symbols of the same type into a higher-paying one.

The awarded features play out once the Avalanches stop. Both the Generator and the Galaxy Meter go back to zero whenever a new spin begins, so progress never carries from one spin to the next.

Our first real run came on an ordinary spin. An Avalanche had already paid 3.50 when the first sphere lit up green for Line Transform, and the whole top row filled with red 7s.

Five 7s in a row added 15.00 on their own, and the spin settled on 18.50.

🔮 Mega Star and the Multiplier Collect Meter

Every three Scatters that land in the same spin award Mega Star, and the Scatters also clear away and start an Avalanche of their own. Once the grid stops paying, a 2x2 Starburst Wild is placed at random.

After those wins are paid, the winning symbols vanish and 2 to 5 regular Wilds drop in during the next Avalanche. Mega Star always plays before any features waiting in the Generator.

On one of our Mega Star rounds, three plasma orbs landed together in the top two rows, flaring white as they arrived. On another, the 2x2 Wild covered a block across the first two reels, with the rainbow star stretched to four times its usual size.

When Mega Star activates, some of the Scatters can come stamped with a multiplier. Those values start the Multiplier Collect Meter in the gold box beside the reels, they add together, and the total boosts every win until the round ends. Two 2x orbs, for example, make 4x.

🌠 Galaxy Star and the Galaxy Meter

Galaxy Star arrives with the fifth feature from the Generator. The grid grows to seven reels of seven rows, and a 3x3 Starburst Wild lands at random.

Once that first wave of wins clears, 4 to 8 regular Wilds fall onto the grid. When the grid finally stops paying, any features still waiting in the Generator are triggered.

The giant Wild also switches on the Galaxy Meter, the ring around the orb under the logo. Every win adds to it, and every 50 wins award Galaxy Star again, with the count starting over.

Ours came through Galaxy Star Bonanza, which opens the round with all five Generator slots filled and a multiplier drawn at random. The backdrop turned a fiery crimson, an orange planet rose behind the grid, and the meter beside the reels settled on 10x.

Three Wilds stood stacked down the first reel early on, and the win had already reached 250.00. Then the Upgrade banner flashed under the Generator, every orange gem on the grid lit up with a pink glow, and the total climbed to 357.50.

When the last Avalanche settled, still under that 10x, the round had paid 420.00.

🚀 The Elevate Menu

The Elevate button opens a menu of five options, and only one can be used per game round:

• Bonus Boost, 3x the bet: raises the chance of reaching Galaxy Star.
• Mega Star, 10x: plays Mega Star, with one free main game spin guaranteed to land 3 Scatters.
• Boosted Mega Star, 50x: plays Mega Star with the Multiplier Collect Meter switched on, and at least 2 of the 3 Scatters carry multipliers.
• Galaxy Star, 100x: guarantees reaching Galaxy Star.
• Galaxy Star Bonanza, 500x: starts Galaxy Star with five features awarded and a random multiplier between 2x and 75x.

Every one of them returns 96.00%, the same as ordinary play. The price is set by your bet, so it changes as the stake does.

🤔 Is This Slot For You?

Starburst Galaxy suits players who loved the original’s look but wanted more going on underneath it. A single spin can run through several Avalanches, a feature or two and a grid that doubles in size, all while keeping the calm, glittering style.

It also suits anyone who likes to choose their own pace. Bonus Boost costs little, Mega Star is a modest step up, and the bigger Elevate options let you jump straight to the 7x7 grid. Anyone hoping for the old, simple loop of one spin and one result should know that a session here is busier, with more to track on the left of the screen.

The obvious comparison is the original Starburst, where the same gems pay both ways across ten fixed lines and an expanding Wild earns a respin. Galaxy keeps the look, swaps the lines for cascading rows and columns, and adds the feature ladder on top.

🌟 VistaGamble’s Honest Assessment

Starburst Galaxy keeps everything that made the original recognisable and builds a far deeper game underneath it.

➕ The Positives

• Wilds born from wins: every cleared line leaves a Wild behind, so one good Avalanche often feeds the next.
• A ladder you can see: the five spheres under the logo show exactly how close the next feature and Galaxy Star are.
• One return across the board: the base game and every Elevate choice sit at 96.00%, so the route you pick never costs you in return.
• A bigger ceiling: the 17,288x top win sits far above what the original could offer.
• Familiar on sight: the gems, the 7 and the rainbow star carry over, polished for a deep-space setting.

➖ The Negatives

• Progress that never carries: both counters wipe clean with each new spin, so a near miss leaves nothing behind.
• Low gems for a long stretch: purple and blue pay 0.25 for three, so the small wins stay small until features arrive.
• More to follow: meters, spheres and an Elevate menu ask for more attention than the original ever did.
• A long climb to the big grid: five features at five wins each means 25 wins in a row inside a single spin before Galaxy Star opens on its own.
• A low ceiling on stakes: the €20 maximum bet keeps high rollers well below what many modern slots allow.

🔒 Conclusion

Starburst Galaxy takes a classic that ran on simplicity and turns it into a slot about momentum. Wins leave Wilds, Wilds build more wins, and five of those in a row open up features that can stretch the grid to 7x7.

Our Galaxy Star Bonanza round showed just how high it can climb, with a 10x multiplier lifting the total all the way to 420.00. If that has you ready for more, head over to our NetEnt lobby, where the studio’s whole catalogue is waiting to be played for free!

Frequently Asked Questions❓

Where does a new Wild land after a win?

In the middle of the line that just cleared. If that line has an even number of symbols, it shifts one step left on a row or one step up on a column.

How many wins does it take to reach a feature?

Five consecutive wins in the main game earn one. Once five features have been earned, Galaxy Star opens.

What changes when the grid grows to 7x7?

A 3x3 Wild lands, 4 to 8 more Wilds follow after wins clear, and lines of six or seven become possible. The Galaxy Meter also starts counting towards another Galaxy Star.

How do Scatter multipliers combine?

Their values are summed in the Multiplier Collect Meter, and that combined figure multiplies each later win in the same round.

Is the RTP different for Elevate options?

No. Normal spins and all five Elevate purchases share the same 96.00% return.

What is the cheapest way to improve your Galaxy Star chances?

Bonus Boost costs 3x the bet and improves your odds of the 7x7 round. A guaranteed Galaxy Star costs 100x.
