The familiar charm—supercharged? In our Starburst Galaxy review, we are going to talk about NetEnt’s sequel to the classic Starburst. Whereas the original game (and even its XXXtreme version) offered a simplicity that was the key draw, in Galaxy, things take a 180-degree turn. The game becomes better in graphics and sound, switches to a cluster pays system, and introduces gimmicks with a learning curve. If you are a casual slot lover for whom the simplicity of Starburst was what set it apart, then the new 96% RTP Starburst Galaxy’s 25,000x max win can be a distant dream for you. Read our review to find out more!
Starburst Galaxy features a 5-reel, 5-row layout with the possibility of expanding to 7x7 during certain bonus features. Instead of traditional paylines, the slot game uses a Cluster Pays mechanic, where winning combinations are formed by landing three or more matching symbols adjacent to each other either horizontally or vertically.
With an unconventional but feels-just-right betting range of £0.2 to £28 that I am sure some market research is the perpetrator of, you have some hard limitations on how you play the game. But that is none of the game’s several drawbacks that we will unpack down the line.
Of course, NetEnt was not going to let go of the variable RTP mechanic with their next banger. After all, it has brand value—and folks are going to spin the reels anyway. There are three RTP variants: 88%, 94%, and 96%. Just make sure you are on an online casino reputable enough to offer the 96% variant.
The max win is a hefty 25,000x—definitely much higher than the 500x/spin with Starburst and, well, different from the 200,000x in XXXtreme. You can go closer to that lucrative 25,000x through the game’s various bonus features such as the Galaxy Star and Mega Star. The payouts, only if you are lucky, are massive in these.

The atmospheric sound is really well done, the charm of the original Starburst is well-preserved, and the graphics are remarkably updated for a stellar experience. All in all, in terms of audio and visual design, Starburst Galaxy is an excellent example of the level of polish modern game providers can offer to players.
The game carries forward the cosmic theme of its predecessors and does justice in doing that. The background is a deep, dark expanse of the cosmos with glowing stars and distant planets for a mysterious and dynamic tone. The soothing cosmic sounds build up, ever so gradually as the reels spin, for an experience that complements the space-themed design perfectly.
The symbols are familiar—vibrant gemstones and classic symbols leading the way. The lower-paying ones are the coloured gems including purple, blue, red, and green. The higher-paying ones include the red 7, BAR, and the yellow diamond. The Wild is the iconic Starburst symbol and the Scatter is the star.

Developed by a leading provider, based on HTML5, and released in late 2024 when the world is gambling on mobile phones—suffice it to say that Starburst Galaxy is as good as they get when it comes to mobile-optimised slot game experiences.
Setting a bet is effortless, all the options rearrange nicely on the mobile (vs. the desktop), and both the portrait and landscape view on mobile devices are simply perfect.
Whereas on the surface level, Galaxy looks like a better Starburst, it is a wholly different game when it comes to the bonuses. There is plenty of stuff here. It seems as if NetEnt has packed the game with a host of buzzword features starting right from Avalanches, a Feature Generator, a Multiplier Collect Meter, and feature buys to the typical wilds and the thematic bonuses of Galaxy Star, Galaxy Star Meter, and the Mega Star. Yes, it is a lot to keep track of. Starburst vs. Starburst Galaxy is going to be the perfect case study of bloating a game—for better or worse.
This is central to the gameplay here. Five consecutive wins will trigger the Generator, filling up a progress meter. Once the meter is full, one of the following random modifiers is going to be triggered:
It is a fresh mechanic and can keep things exciting for longer.
Activated after the fifth modifier in the Feature Generator is triggered, the Galaxy Star is one of the most lucrative aspects of the game. The game grid will expand to 7x7 from 5x5, and a 3x3 Wild is placed randomly on the reels. As one might expect—this leads to a considerably larger win potential with multiple Wilds appearing on the reels after each Avalanche. In many ways, this is the highlight in Starburst Galaxy.
So, in other words, each time a 3x3 Wild symbol appears on the reels, it fills the Galaxy Meter. Once the Meter reaches 50, the Galaxy Star initialises the Galaxy Star feature. The Meter will reset after the bonus round ends.
Landing three or more Scatter symbols will trigger the Mega Star feature. This one will place a 2x2 Wild on the grid. Once the wins are calculated, up to five regular Wild symbols are added to the reels during the next Avalanche. While this feature is in play, the Scatter symbols can carry a multiplier (2x, 3x, 5x, 10x, or 25x)—which are collected in the Multiplier Collect Meter (duh). These multipliers are then applied to all wins, making the Mega Star another high-reward opportunity for players.
Bonus/feature buys are becoming more common by the day. Elevate (fancy name for Bonus Buy) is a feature using which you can buy access to some of the more exciting bonus features. A shortcut to big rewards or a way to burn your bankroll and call it a day sooner?
Starburst Galaxy takes everything that made the original Starburst so iconic and turbocharges it with new features, slick graphics, and exciting bonuses. While it maintains the cosmic charm and familiar feel of its predecessor, the game now offers a more complex, feature-packed experience, making it an ideal pick for players who enjoy an added layer of excitement and big win potential.
The medium-high volatility and 25,000x max win potential are nice perks, but the three RTP variants can fool you. It is an engaging sequel to a popular game that can only be tagged as a blend of nostalgia and modern mechanics.
Rating: 7.5 (Good)
Starburst Galaxy was much-anticipated, even by yours truly. Upon trying the game, I was instantly taken back to the times of Starburst—a game that celebrated its 10th anniversary in 2022. Starburst Galaxy is an attempt to take the core space-themed experience and the brand value of the Starburst IP, mix in a few chic, modern features, and package it all into a 2025-ready banger that will quickly become the staple of all top UK online casinos. So far, the plan seems to be succeeding.
