Starburst Slot Review

NetEnt is a Stockholm founded developer, now part of the Evolution group, with a long catalog of premium video slots including Gonzo’s Quest, Dead or Alive and Twin Spin. Starburst is its calling card. The reason it became so popular is not a huge top prize or a complex feature set. It is the opposite: the game is fast, forgiving, easy to understand in one spin, and it pays small wins often enough to feel rewarding without draining a bankroll quickly. That is exactly why operators lean on it for wagering requirements and why new players are so often handed Starburst free spins as a first taste of real money slots. It is a video slot at heart, and its bright jewels against deep space give it a clean, arcade like outer space theme.

This review covers the family as it exists in the legal United States online market: the original Starburst and its 2021 successor, Starburst XXXtreme. The two share a name, a wild symbol and a starfield backdrop, but they are built for opposite kinds of player. The original is a low volatility grinder with a 500 times cap. XXXtreme is a high volatility reworking with a 200,000 times cap and a bonus buy. Getting the contrast right is the whole point, so this review keeps them clearly separated throughout.

Quick view specifications

The table below covers the flagship title, the original Starburst. The XXXtreme specifications are laid out separately in the version comparison and in its own dedicated section further down.

A note on the maximum win figure, because it confuses players. Starburst advertises a 50,000 coin top win, but the game also enforces a hard ceiling of 500 times your total stake on any single spin. At the coin values most players use, the 500 times cap is the real limit you will run into. It is a low volatility slot, so the top prize is modest by modern standards and is meant to be. For a fuller explanation of how the return figure is calculated, see the RTP guide.

Version comparison

Two Starburst titles are relevant to legal United States online lobbies. Both are online video slots, not cabinet exclusives. The table sets the flagship and its high volatility successor side by side so the differences are obvious at a glance.

The headline gap is the top end. The original caps at 500 times your stake. XXXtreme reaches 200,000 times, a 400 fold increase, and it trades the original’s steady low volatility rhythm for high volatility swings. Neither game is a land-based only release. There is no cabinet exclusive Starburst being presented here as if it were playable online, and if you ever see a Starburst branded physical machine, it is not one of the two online titles reviewed on this page.

Game overview and how it plays

Starburst is built for speed and clarity. The grid is five reels and three rows, and the game evaluates wins in both directions, so a matching combination that starts on the leftmost reel pays, and so does one that starts on the rightmost reel. That both ways design effectively doubles the ways a given line can connect, which is a big part of why the game hits so frequently for a 10 line slot. There are no scatters to chase, no free spins to trigger and nothing to buy. Every spin either lands a paying combination, sets up the wild feature, or comes up empty, and the whole thing resolves in a couple of seconds.

The symbols are colored gems plus a small set of classic bar and seven style icons, and the star is the only special symbol. When a Starburst Wild lands on one of the three center reels, the feature fires. Because the base math is low volatility, most sessions are a rolling series of small wins from matching three, four or five gems in a row, punctuated by the occasional wild respin that stacks several line wins at once. The game is intentionally friendly to small stakes and long sessions, which is why it is the slot casinos most often attach to no deposit offers and welcome free spins. If you want to see how variance shapes the feel of a session like this, the volatility guide is a useful companion, and Starburst sits firmly in the low volatility category.

Symbols and what they pay

Starburst uses a compact symbol set. There are no themed premium characters and no card ranks. Instead the reels are stocked with colored jewels and a handful of retro icons, ranked from low to high by color, plus the single wild. Payouts are quoted as coin values for combinations reading in either direction, and because the game pays both ways, a five gem line is not the only route to the top of a symbol’s pay.

Gem symbols, low to high

• Purple, green, blue, orange and yellow gems: the standard paying symbols, ranked roughly in that order from lowest to highest value. Three of a kind starts most wins, and five of the top gem across a line is the best straight symbol payout. The yellow and orange jewels sit at the top of the gem hierarchy.
• The bar and the lucky seven: classic slot icons that pay among the higher values in the set, a nod to the traditional fruit machine styling under the space theme.

The Starburst Wild

• The multicolored star is the only special symbol in the game. It substitutes for every gem and icon to complete a winning combination in either direction. It appears only on the three center reels, reels 2, 3 and 4.
• It expands and sticks. When a wild lands, it grows to cover the entire reel it is on, locks in place, and awards a respin. That is the game’s entire feature engine.

Bonus symbol cross-check

This family does not use a scatter or a dedicated bonus icon in either version, so the honest answer to the usual question is that there is no shared scatter symbol to compare. What both games share is the star wild. In the original Starburst, the special symbol is the Starburst Wild, which expands and grants respins. In Starburst XXXtreme, the special symbol is again a Starburst Wild, but it behaves differently: it carries a random cash multiplier. So the two versions use the same symbol concept, the star, as their one special symbol, but the wild does a different job in each. Neither game has a separate scatter or a separate bonus symbol. The per version breakdown is simple: original Starburst equals expanding wild with respins, XXXtreme equals expanding wild with an attached multiplier.

How to trigger the feature

Starburst has no scatter to collect and no minimum number of symbols to line up for a bonus. The feature is triggered purely by landing a wild.

• Land at least one Starburst Wild on reel 2, 3 or 4 in any spin. A single wild is enough to start the feature. Wilds never appear on reels 1 and 5.
• The wild expands to fill its entire reel, becomes sticky, and the game awards one respin with that reel held in place.

There is nothing to buy and nothing to hunt for beyond the wild itself. Because the wild lands reasonably often on the three center reels, the feature shows up regularly, which is another reason the game feels generous despite a modest top prize.

How the feature works

The original Starburst has one feature, the expanding wild respin, and understanding it is the key to the whole game. When a Starburst Wild lands on reel 2, 3 or 4, it expands to cover all three positions on that reel, locks in place as a sticky wild, and triggers a respin while the other reels spin again. Because an expanded wild fills an entire center reel, it contributes to every line passing through it, in both directions, so a single expanded wild can turn a dead spin into several simultaneous line wins.

The feature can build. If another Starburst Wild lands on a different center reel during a respin, that new wild also expands, sticks, and awards a further respin, with all expanded wilds staying locked. Since wilds only appear on the three center reels, you can hold a maximum of three expanded wilds at once, which means a run of up to three respins in total. The dream outcome is all three center reels covered by expanded wilds, which forces matching combinations across every line and produces the game’s biggest payouts up to the 500 times cap. This respin chain, not a free spins round, is where Starburst’s meaningful wins come from.

Starburst XXXtreme plays its feature very differently, and it is covered in full in its own section below. In short, XXXtreme keeps the expanding sticky wild respin idea but attaches a random multiplier to each wild, and lets multiple wild multipliers add together, which is how it reaches a top prize 400 times larger than the original.

Version by version

Starburst (2012)

The original Starburst launched in 2012 and is the version that made NetEnt a household name among slot players. It is a five reel, three row game with 10 bet lines that pay in both directions, a default return to player of 96.09 percent, low volatility, and a maximum win of 50,000 coins that is capped at 500 times the total stake on any single spin. The bet range runs from 0.10 up to 100.00 per spin using NetEnt’s level and coin value system, which suits penny players and higher stakes players alike. There is no scatter, no free spins round and no bonus buy. The entire game rests on the Starburst Wild, the multicolored star that lands only on the three center reels, expands to fill its reel, sticks, and awards a respin, chaining up to three respins if further wilds appear.

What has kept the original relevant for well over a decade is not its ceiling, which is low, but its rhythm. The both ways evaluation and the frequent center reel wilds produce a steady stream of small wins that make the game feel alive without burning through a bankroll. That low volatility profile is why operators pair it with welcome offers and wagering requirements, and why it remains a fixture in regulated United States lobbies that carry NetEnt content across New Jersey, Michigan and Pennsylvania. It is an online, HTML5 title through and through. Any physical machine bearing the name is not this game, and nothing about the online version is being withheld as a land-based exclusive.

Starburst XXXtreme (2021)

Starburst XXXtreme arrived in 2021 as NetEnt’s high volatility reimagining of the classic, built explicitly for players who found the original too tame. It keeps the starfield look, the five by three grid and the sticky expanding wild concept, but almost everything else is turned up. The layout uses 9 bet lines, the volatility is high, the default return to player is 96.26 percent, and the maximum win explodes to 200,000 times the total stake, a figure the original never came close to. The bet range starts around 0.10 per spin, with the upper limit varying by operator, so the exact maximum stake should be confirmed in each lobby’s own bet menu.

The transformation is in the wild. In XXXtreme, Starburst Wilds still land only on the three center reels, expand and stick for a respin, but each wild now carries a random cash multiplier drawn from the set 2x, 3x, 5x, 10x, 25x, 50x, 100x and 150x. When more than one wild is in play, their multipliers add together rather than replacing one another, so three wilds each carrying the top 150x value combine into a single 450x multiplier applied to that spin’s line wins. Stacking high multipliers on a screen full of expanded wilds is how the game reaches its 200,000 times ceiling, and it is also why the game runs cold for long stretches. This is a high volatility slot in the truest sense, and it belongs in the high volatility category rather than beside its gentle predecessor.

XXXtreme also adds something the original never had: a bonus buy, branded XXXtreme Spins. For 10 times your stake you can buy a spin with one Starburst Wild guaranteed to land, and for 95 times your stake you can buy a spin with two wilds guaranteed. This puts it in the bonus buy slots category and gives impatient players a direct route into the multiplier action, at the cost of a much larger stake. The buy feature is restricted or unavailable in some regulated markets, so its presence depends on the operator and state. Like the original, XXXtreme is an online HTML5 title, distributed to regulated United States casinos through NetEnt, and it is not a land-based machine.

Starburst XXXtreme specifications

Mobile play

Both Starburst titles are built in HTML5 and run natively in the browser on iOS and Android with no download, as well as on tablet and desktop. The interface is minimal by design: a spin button, autoplay, a bet and coin selector, and the paytable. The bright star wild and the expanding reel animation stay legible on small phone screens, and portrait play scales cleanly. There is no separate app to install for the games themselves; they load inside your regulated casino’s own app or mobile site. For more on playing on a phone, see the mobile slots page.

Betting, stakes and how a session plays

Starburst uses NetEnt’s coin value and level system rather than a single line bet, but the practical result is a spin cost that runs from 0.10 at the floor up to 100.00 at the ceiling. All 10 lines are always active in the original, so you are never choosing how many lines to play, only how much each spin costs. That fixed line design keeps the both ways evaluation fully live on every spin, which matters because the frequent center reel wilds only pay across lines that are switched on. For newcomers, the low starting stake is part of the appeal, and it is why a handful of free spins on Starburst can be stretched into a long first session.

Because the original is low volatility, the session shape is predictable. You will see small wins land often, most of them a fraction of your stake up to a few times it, with the expanding wild respins delivering the larger hits. The lack of a bonus round to chase means there is no long dry spell waiting for a trigger, which is the opposite experience of a high volatility title. That gentle curve is exactly why the game is a poor fit for jackpot chasers and a great fit for players who want screen time and steady action. XXXtreme flips this completely: the same 0.10 entry point can vanish across dozens of empty spins while you wait for wilds and multipliers to align, so bankroll sizing there should assume long cold runs. For the fundamentals of stake sizing and reading a paytable, the how to play guide covers the basics.

RTP configurations

Like most widely licensed NetEnt games, both Starburst titles can ship to operators in more than one return to player setting. The flagship and most common build of the original is 96.09 percent, but lower configurations exist and are loaded by some casinos, which can move the long run return meaningfully below that headline number. Starburst XXXtreme runs a default of 96.26 percent, with a slightly different figure applying when the XXXtreme Spins bonus buy is used. The game math and features are identical across builds; only the long run return changes. The single most important thing you can do before playing either title for real money is open the game’s own information or help screen inside your casino and confirm which return to player build that specific operator has loaded. Do not assume the headline figure applies.

Strategy and practical tips

Starburst is a fixed math slot, so nothing changes the underlying odds. What you can control is how you play to match how each version actually pays.

• Confirm the RTP build first. This is the one setting that materially changes your expected return. Two lobbies running the same game at different configurations play identically but return differently over time. Check the info screen before you commit real money.
• Match the version to your goal. Choose the original for a relaxed, long, low variance session, and choose XXXtreme only if you genuinely want to chase a large multiplier and can absorb long losing runs to do it.
• Size XXXtreme bankrolls for cold streaks. High volatility means the money is concentrated in rare big hits. Bet small relative to your bankroll so you are still spinning when the multipliers finally stack.
• Treat the XXXtreme Spins buy with caution. Paying 10 times or 95 times your stake for a guaranteed wild does not change the return to player in your favor. It buys access to the feature, not an edge, and it burns bankroll fast.
• Use demo mode to feel the variance. The gap between the two versions is dramatic. Trying each in free play first shows you the base rhythm before you risk real money.

How the Starburst family compares

The original Starburst defined a whole category of clean, low volatility, feature light slots, and its closest relative is NetEnt’s own Twin Spin, which shares the retro symbols and the emphasis on frequent small wins over a big bonus. Against modern high mechanic games with elaborate free spins rounds, Starburst is intentionally old fashioned: no scatter, no free spins, one wild. That restraint is its strength and the reason it aged so well. It is worth being precise about what does not exist in this family, because lookalikes are common. There is no official Starburst Megaways, no progressive jackpot edition and no cluster pays version from NetEnt. The original and XXXtreme are the two titles, and any product marketed under the name with a mechanic not described on this page is not a genuine NetEnt release. Starburst XXXtreme, by contrast, sits alongside the current wave of high volatility, high ceiling releases with bonus buys, where the appeal is a rare shot at a life changing multiplier rather than steady play. The two are best understood as bookends. One is the friendliest slot in the lobby, the other is among the more punishing, and they happen to share a name and a starfield.

Where to play

Starburst and Starburst XXXtreme are online titles found in regulated United States casino lobbies that carry NetEnt, not sweepstakes only or land-based games. To find licensed operators in your state and confirm which specific version is live, start with the full directory of legal casino sites and search each lobby by name. Availability changes, so the lobby search is the final word on whether a title is playable right now.

Verdict

The two Starburst games solve for opposite players from the same starfield. The 2012 original is a low volatility classic that pays small and often, tops out at 500 times your stake, and earns its place through a clean expanding wild respin that anyone understands on the first spin. It is the reason the game has been the industry’s default free spins slot for over a decade. Starburst XXXtreme is the high volatility answer, keeping the sticky expanding wild but bolting on random multipliers that add together up to 450 times, a bonus buy, and a ceiling of 200,000 times the stake that can run ice cold on the way there. Pick the original for a relaxed session and the successor for genuine top end chasing, and in either case confirm the return to player build and the exact game in your operator’s lobby before you play. If you are weighing this family against other slots, the guide on how to choose a slot is worth a read.
