This sequel retains the 5×3 layout and cosmic gem theme, but swaps the originalβs low volatility for a high volatility math model that can produce far swingier sessions and much bigger spikes. RTP is offered in configurable versions depending on the casino, with the commonly seen setting around 96 per cent. The headline features are Starburst Wilds that expand and trigger respins, Random Wilds that can drop extra Wilds, and Wild multipliers that can reach 150x per Wild and stack up to 450x when multiple Wilds land together.
About Starburst XXXtreme
Starburst XXXtreme is an online slot game created by NetEnt, one of the leading game developers. Released in 2021, it quickly became a favourite among Irish punters. This game is a sequel to the popular Starburst slot and keeps some familiar features while offering a more intense experience with higher volatility.
You can find NetEntβs games, including Starburst XXXtreme, at trusted online casinos in Ireland. Many of these sites are recommended by Zamsino, so it is handy to jump in and give the game a lash. The game uses 9 fixed paylines that pay from left to right only, so unlike the original Starburst, wins are not counted both ways. That single change alone shifts how often you hit, and how large the hits can be when the Wild features connect.
Free Play and No Deposit Bonuses
Zamsino Ireland features gambling sites with plenty of free spins and no deposit bonuses. For example, Leon Casino lets you spin the Lucky Wheel when you register, allowing you to win up to 50 free spins without depositing anything. You can even use these spins to try out Starburst XXXtreme.
Always check the bonus terms, including which games spins can be used on, wagering requirements, max cashout, and any bet caps. Many Irish casinos rotate eligible titles, so availability for Starburst XXXtreme can vary by promotion and time period. Sound advice is to read the small print before you hit spin, and make sure the offer is valid for players in Ireland.
Game Details
If you want to make the most of Starburst XXXtreme, read this part of the review carefully. This thrilling slot takes the beloved classic Starburst to a new level with enhanced features, bigger payouts, and an adrenaline-pumping gaming experience.
Theme
The theme has stayed constant, though plenty else has changed. In terms of audiovisual presentation, Starburst XXXtreme does not differ much, and rightly so. The vibrant cosmic visuals and dazzling gemstones still give the game its distinct charm, while the smooth animations and ambient soundtrack provide a mesmerising experience. On modern phones and tablets, the visuals scale cleanly and the reels remain responsive, which matters when respins can chain quickly. It runs grand on mobile data or Wi-Fi, with no fuss.
Bonus Features
NetEnt has made some changes, including removing the pay-both-ways system, but they have added exciting multipliers of up to 150x on a single Wild for a more thrilling experience. Two XXXtreme Spins betting options sit beside the main spin button. The first guarantees a Starburst Wild and increases your stake by 10x. The second option gives you two guaranteed Starburst Wilds on the same spin, but it costs 95x your stake.
Starburst Wilds are the highlight, expanding to cover an entire reel and awarding a respin. During these respins, the Wilds stay locked in place, and if another Wild lands, the process repeats. The Random Wilds feature can inject up to three Wilds onto reels 2 to 4, and each Wild can carry a multiplier from 2x up to 150x. If more than one Wild is visible, their multipliers add together, which means the combined multiplier can reach a huge 450x in rare cases.
Tip
If you want more frequent feature triggers without shelling out for the 95x option, the 10x buy can be a disciplined middle ground, but it still needs a bankroll that can absorb streaks where Wilds miss paylines. Grand if you are patient, but do not chase losses.
Betting Range & Payouts
The game is played on a 5-reel, 3-row setup with 9 fixed paylines, which is one less than the 2013 version. Players can bet between β¬0.10 and β¬50 per spin. With higher risk comes a much bigger reward. The maximum prize is an incredible 200,000x your stake. Line symbols are classic Starburst icons, with the BAR symbol as the top payer, then 7s and coloured gems. Since wins form left to right only, positioning Wilds on the middle reels, especially with multipliers, is the key to unlocking the slotβs top-end potential.
A quick example
Landing a Wild with a 50x multiplier on reel 3 that connects a BAR five of a kind, then adding a second Wild on the respin with another 50x, would apply a 100x combined multiplier to the line win. That is how seemingly modest lines can suddenly turn into sizable payouts.
How to Play Starburst XXXtreme Slot
To start playing Starburst XXXtreme, set your desired stake by adjusting the bet and bet level. Once your stake is established, hit the spin button and launch into an exciting space adventure. Watch for the highest-paying symbol, the BAR symbol, which can grant a max win of up to 150.00x your bet on a single line.
The game gets even more thrilling with Wild symbols that not only award respins but also activate lucrative multipliers. For an added edge, players can enable the XXXtreme Spins feature to guarantee Wild appearances, amplifying the potential for massive rewards. If you prefer standard spins, consider session budgeting. For example, decide on a fixed number of spins or a stop-loss, since the high volatility can produce long dry spells between standout hits. Keep an eye on your balance and mind yourself.
XXXtreme Spins Feature
The XXXtreme Spins feature allows you to ensure that you land at least one Wild symbol on the middle reels, boosting your chances for substantial wins. Players can select from two options in this feature: 10x your bet for 1 guaranteed Starburst Wild or 95x your bet for 2 guaranteed Starburst Wilds.
This feature significantly increases the frequency of Wilds on the middle reels and can unlock the potential for some truly huge wins when multipliers stack. It adds an extra layer of excitement and strategy, turning individual spins into high-impact moments, but the high cost means results can still vary greatly from spin to spin. It is a bit of a rollercoaster, so only stake what you are comfortable with.
User Experience
The first thing I noticed was how similar the two games look. There is a good reason for that. Starburst XXXtreme was not designed as a visual update. It appears it was made to target a different audience. In my opinion, NetEnt did a fantastic job.
The addition of XXXtreme Spins is great. They make every spin more exciting, even though they are pricey. You get what you pay for. The multipliers are a game-changer. A single Wild can carry up to 150x, and with multiple Wilds the combined multiplier can reach 450x, adding a new level of suspense and excitement. I also like how the potential for winning has increased significantly compared to the original.
Being the sequel to one of the most popular slots ever is not easy, but Starburst XXXtreme lives up to the hype and then some. Sessions can be swingy, which suits players who enjoy volatility, while fans of the classicβs frequent small hits may prefer to stick with the original. Fair play if you prefer the steady pace of the first game, but if you are after drama, this one is for you.
Starburst XXXtreme vs. Other Online Casino Games
Starburst XXXtreme is a fun and visually striking game with its colourful, gem-themed design. It also offers exciting features like expanding Wilds and respins, giving players a chance for big payouts in similar games. Compared with the original Starburst, you lose both-ways pays but gain Wild multipliers, far higher volatility, and a substantially higher max win ceiling.
Compared to other casino games, like table games or different slots, the choice comes down to personal preference. Table games are more strategic and often include social interaction, while slots focus on fun themes, graphics, and bonus features. If you enjoy modern high variance slots, Starburst XXXtreme sits closer to feature-rich titles where single spins can swing a session, while still keeping the clean, approachable feel that made Starburst famous.
