Starburst Galaxy Slot

Starburst Galaxy RTP, Details & Wager Limits

The Starburst Galaxy slot game by NetEnt takes place across a 5×5 reel setup in the base game, but it can expand to a 7×7 grid. There are no traditional paylines—instead, it uses cluster pays. To score a win, you need at least 3 matching symbols lining up next to each other without gaps, horizontally (side to side) or vertically (up and down), starting from any spot on the reels. When this kicks in, an avalanche is triggered, where winning symbols vanish, and new ones drop in.

The +/- controls allow you to adjust your stake from 20p to £28—a bit limited compared to other online slots that cater better to high rollers. If you’re playing at a Starburst Galaxy casino outside the UK, the autoplay function lets you set up automatic spins for 5, 10, 25, 50, or 100 rounds.

The Starburst Galaxy RTP sits right at the industry average of 96%. Its high volatility is great if you’re risk-tolerant and can handle the wait between wins. After all, this title delivers larger payouts, albeit less frequently.

You’re looking at a heavy Starburst Galaxy max win of 25,000x the stake. Based on my time with the free-to-play slot version, this is achievable by triggering the high-paying clusters to fuel the Feature Generator and unlock the Galaxy Star. Also, aim to activate as many bonus features as possible, like the Random Wilds, Expanding Wilds, Line Transform, and more, to boost your odds.

Theme: Step Into a Galactic Adventure Bursting With Light and Colour

The Starburst Galaxy slot game layout captures the feel of deep space with a refreshingly clean, minimalist touch. The grid rests against a star-speckled background with distant galaxies that glow softly, creating a vastness that, in my view, extends beyond the reels. Having said that, NetEnt has still managed to retain that polished essence from the original Starburst slot and elevated it further with sharper and more refined visual elements.

The game’s audio keeps a simple and steady background tone, which may feel a bit repetitive after some time. However, the sound effects that kick in with each spin and win break the loop and add all the missing energy. A few of them actually caught me off guard—I wasn’t prepared for such intensity.

The symbols in Starburst Galaxy stay on the simple side and feature familiar pay symbols like purple, blue, orange, green, and yellow gems alongside the iconic 7 and BAR icons. You’ll also come across 5feature symbols, including wilds.

Take a look at the full table below:

Symbol	Payout/Info
Purple Gem	3 to 7+ = 0.25 to 10 x stake
Blue Gem	3 to 7+ = 0.25 to 10 x stake
Red Gem	3 to 7+ = 0.5 to 20 x stake
Green Gem	3 to 7+ = 0.5 to 30 x stake
Yellow Gem	3 to 7+ = 0.75 to 40 x stake
7	3 to 7+ = 0.75 to 50 x stake
Golden BAR	3 to 7+ = 1 to 250 x stake
Wild	Substitutes for all other symbols above
Scatter	Triggers the Mega Star Feature when three appear on the reels; can carry multipliers

Starburst Galaxy Mobile Slot

In true NetEnt style, the Starburst Galaxy mobile slot uses HTML5 tech, so it runs perfectly well on smartphones and tablets, whether that’s Android or iOS. The interface mirrors the desktop experience very closely, except for the menu shift to the location beneath the reels. The background still maintains its clarity, even with the reels filling the screen.

Still, I highly recommend hiding the toolbar for a better-optimised space, no matter which orientation you choose when playing at your favourite mobile casino.

Starburst Galaxy Bonus Features

Starburst Galaxy brings out 5 very engaging bonus features that blend familiar elements with fresh twists. You’ll see classic wilds similar to those in the predecessor slot Starburst XXXtreme, alongside creative features like the Feature Generator, Galaxy Star Feature, Mega Star Feature, Multiplier Collect Meter, and a feature buy option.

Let’s break down each one in detail.

Wild Symbols

A wild symbol is placed at the centre of a winning combo if it clears without a wild in Starburst Galaxy. If there was an even number of symbols in the cleared combination, the wild goes to the left centre for horizontal wins or to the top centre for vertical wins. If two winning combinations overlap, each gets its own wild, but if they meet at their centres, only one wild will appear in that intersection.

Wild symbols substitute for all symbols except scatters and can create new winning combinations. If 3 or more wilds (up to 7 in the expanded grid) appear in a line and cannot form a winning combination with other symbols, they pay out the highest possible winning combination based on the paytable.

Feature Generator

Each winning combination in the Starburst Galaxy slot fills the Feature Generator meter in the main game. After 5 consecutive wins, the game randomly activates one of the 5 available features.

Here’s a quick rundown:

• Destroy removes 1 or more random symbol types from the reels.
• Random Wilds replaces 3 to 9 symbols with wilds.
• Expanding Wilds turns all wilds into stacks of 3.
• Line Transform fills an entire row or reel with a randomly selected payout symbol.
• Upgrade boosts 1 or more symbols on the reels to a higher-value version.

Galaxy Star Feature and Galaxy Meter

The Galaxy Star feature activates when the fifth option in the Feature Generator is awarded. When triggered, the play area expands to a 7×7 grid, and a 3×3 wild symbol is randomly placed on the reels, creating a chance for bigger wins. After wins are calculated, all winning symbols disappear, and 4 to 8 regular wilds appear. If no new wins occur, any remaining features in the Feature Generator are activated one by one.

The Galaxy Meter starts working when the 3×3 wild appears on the reels. Each win adds to this metre. When it reaches 50, the Galaxy Star feature is awarded and activated when no more wins occur. Also, the meter resets and starts again, along with the Feature Generator progress.

Mega Star Feature and Multiplier Collect Meter

The Mega Star feature kicks in instead of the traditional free spins you’d find in the best online slots when 3 scatter symbols land simultaneously on the reels. When activated, a 2×2 wild symbol randomly appears on positions without wilds if there are no new wins after an avalanche. Once wins are evaluated and all winning symbols disappear, 2 to 5 regular wilds are randomly added during the next avalanche.

When the Mega Star feature is active, some scatter symbols can come with multipliers (2x, 3x, 5x, 10x, or 25x). These feed into the Multiplier Collect Meter, which displays the combined multipliers that will apply to all wins until the round ends.

Elevate (Not Available in UK Online Casinos)

The Elevate feature in the Starburst Galaxy slot offers several in-game boosts for an extra cost per game round. Here’s the breakdown:

• Bonus Boost increases your chances of hitting the Galaxy Star feature for 3x your bet.
• Mega Star activates the Mega Star feature for 10x your bet, therefore giving you a spin with guaranteed 3 scatters.
• Boosted Mega Star triggers the Mega Star feature and Multiplier Collect Meter for 50x your bet. This spin guarantees 3 scatters, with at least 2 carrying multipliers.

For higher stakes, there are two more options:

• Galaxy Star guarantees the Galaxy Star feature for 100x the bet.
• Galaxy Star Bonanza launches the Galaxy Star feature with all 5 awarded features and a random multiplier (ranging from x2 to x75) for 500x the bet.

Starburst Galaxy Slot

Starburst Galaxy takes the classic Starburst slot to new heights with multiple unique bonus features and a fun expandable setup, but it’s not without its weak spots.

Pros

• Expansive 7x7 grid with cluster pays
• 5 innovative bonus features
• Mega Star feature with multipliers up to 25x
• Smooth mobile experience in both portrait and landscape modes

Cons

• Very limited betting range (up to £28)

Starburst Galaxy has done an excellent job keeping the timeless Starburst charm but with some serious upgrades. Mechanically, it nails the basics but goes further with cluster pays, dropping wilds into cleared wins and charging up those collection meters. It’s a lot to trigger, but it’s also what gives the game its kick. I especially loved how the 5×5 grid can expand to a 7×7 layout.

This game has a strong payout potential as well, with a max win of 25,000x your stake. Still, high rollers might find the betting range a bit limited (the Elevate feature should come in handy in this case when playing from non-UK slot sites).

If you tend to get bored quickly with new online slots, make sure to give the Starburst Galaxy demo a shot—this one’s packed with enough variety to keep you hooked for a good while. Get a feel for the features and decide if it delivers what you’re looking for.
