Pros and cons of Starburst Galaxy

Game details of Starburst Galaxy from NetEnt

Starburst Galaxy uses a 5x5 grid layout that can dynamically expand to a 7x7 grid during specific bonus features. Wins are no longer restricted to traditional paylines; instead, they are achieved using an adjacency system, where at least three matching symbols form combinations vertically or horizontally.

When a winning combination is formed, the symbols of that combination dissolve, allowing new symbols to cascade down. This chain reaction can lead to consecutive wins from a single spin, with the potential to fill the Feature Generator.

The theme of Starburst Galaxy remains rooted in its predecessor's cosmic aesthetic. Vibrant gemstones, golden Bar symbols, and iconic 7s light up the reels against a swirling galactic backdrop, accompanied by an ambient soundtrack that enhances the immersive experience.

The game caters to a broad range of players, with a betting range that starts as low as €0.20 and goes up to €28 per spin. This flexibility makes it suitable for both casual gamers and high rollers.

Starburst Galaxy introduces an array of features designed to keep gameplay engaging and highly rewarding. Each feature contributes to the slot's dynamic nature, ensuring that no two spins feel the same.

Wild symbols

A winning combination created without a wild will leave a wild star in the middle of the combination. This wild can then help create new winning combinations in the next avalanche.

The Feature Generator

The Feature Generator is one of the online slot's most innovative elements. You charge this meter by landing consecutive wins. Once you have five winning combinations, one of five unique features is triggered, in the order of succession.

• Destroy: One or more random symbols are chosen and removed from the grid.
• Random Wilds: 3–9 symbols are replaced with wild.
• Expanding Wilds: Causes all visible wild symbols to expand to a height of three.
• Line Transform: Transforms one row or a reel with the same randomly chosen symbol.
• Upgrade: Enhances one or more randomly chosen symbols to a symbol with a higher value.

Galaxy Star Feature

When you activate the fifth feature from the Feature Generator, the grid expands from its standard 5x5 layout to a 7x7 layout. A massive 3x3 wild symbol is then added to the reels, offering incredible winning opportunities.

After the win was calculated, 4–8 regular wilds appear on the reels, and once there are no more combinations possible, the remaining Feature Generator bonuses are activated.

The Galaxy Meter is also activated with the 3x3 wild and collects symbols from winning combinations. You need to collect 50 winning symbols to activate the Galaxy Star again.

Mega Star Feature

Landing three scatter symbols in a single spin activates the Mega Star feature. This feature places a 2x2 wild symbol on the grid and applies multipliers of up to 25x to all wins in this game round.

Elevate Feature: Bonus Buy options

You can increase your chances of triggering bonus features by activating the Elevate Feature. This significantly increases your bet size, so be careful how much you bet. There is no guarantee that you win back the amount you staked. The extremely high volatility of the NetEnt slot also means that you get many spins without high wins.

• Bonus Boost costs 3x bet and increases your chance to reach the Galaxy Star Feature
• Mega Star costs 10x bet and activates the Mega Star by placing three scatters on the reels that merge into a 2x2 wild.
• Boosted Mega Star costs 50x bet and activates the Mega Star and Multiplier Collect Meter, in which at least two of the three scatters have multipliers.
• Galaxy Star costs 100x bet and guarantees the Galaxy Star feature activation.
• Galaxy Star Bonanza costs 500x bet and activates the Galaxy Star bonuses with five features and a random multiplier of between x2 and x75

Volatility and RTP of Starburst Galaxy

Starburst Galaxy has a Return to Player (RTP) rate of 96%, aligning with industry standards.

The volatility of Starburst Galaxy is listed as very high, which means that the game is risky but can also yield high rewards. You can expect many spins with only lower wins, but you can also get the chance to land a huge win, especially if the bonus features trigger.

Our verdict of Starburst Galaxy

Starburst Galaxy takes everything players loved about the original Starburst slot and enhances it with innovative features, stunning visuals, and a far greater potential for massive wins. A stark difference between this version, and Starburst and Starburst XXXtreme is the high volatility, as both other versions have a much lower volatility.

The expanded grid layout, dynamic gameplay mechanics, and diverse range of bonus features ensure that every spin feels fresh and exhilarating. Whether you're a fan of the classic or new to the series, Starburst Galaxy offers an engaging and rewarding experience.

What's important for you to consider though is the extremely high volatility, which can lead to quick depletion of your balance. However, with a bit of luck, you can also win big. Whether to buy the bonus features is up to you, but we find the 500x bet price at the highest level particularly high, considering the high volatility.

By combining nostalgic elements with forward-thinking innovation, NetEnt has crafted a version that feels both familiar and groundbreaking. The potential for significant payouts, paired with the slot's polished design and captivating gameplay, makes Starburst Galaxy a must-try for slot enthusiasts.
