Starburst XXXtreme: Slot Overview

“Iconic” is a word that gets used too freely, yet if any online slot has earned it, it’s NetEnt’s classic Starburst. First launched in 2013, Starburst is still a hugely popular staple for countless players. That said, it’s also showing its age a bit—especially now that the market has largely shifted toward higher-volatility, bigger-reward titles. To keep the brand feeling current, or to excite players who’ve moved on to punchier games, NetEnt revisited the original with their 2021 release Starburst XXXtreme, keeping a few familiar touches while ripping out the core and replacing it with a dramatically different maths model.

Visually, the Starburst DNA is unmistakable, as the remake looks very close to the original. The space-themed action plays out on a 5-reel, 3-row grid with 9 rather than 10 fixed paylines. Anyone hoping for big innovation can rest assured that losing a payline is the smallest tweak in Starburst XXXtreme. On the audio/visual side there isn’t much else to call out; Starburst XXXtreme occasionally shows a light-speed travel effect behind the reels, but fans of the first game should feel instantly at home with the XXXtreme edition.

With stakes running from 10 p/c to $/€50 per spin, the underlying maths has been rebuilt too, and volatility now sits at the other end of the scale, labelled as ‘high’. The pay-both-ways mechanic has been axed, meaning wins only count when at least three matching symbols land starting from the leftmost reel. If you’re using XXXtreme Spins (covered below), the constant action makes this less noticeable, but in the standard mode the difference is much clearer.

The paytable, however, sticks to familiar ground, using the same 7 pay symbols. You still get 5 glittering gems as the lower-value icons, with 7s and Bars at the top. Those two premium symbols pay 20 to 50 times the stake for five of a kind. Just like before, wilds are central to the action; we’ll break them down next.

Starburst XXXtreme: Slot Features

NetEnt has cut a payline and made the remaining ones pay in a single direction, so you’d expect something serious to justify the ‘XXX’ in the name. In response, NetEnt has introduced multipliers as the trade-off. It may sound straightforward, but simplicity has always been core to the Starburst formula—and here it can deliver some huge moments.

To start with, when you load the game you’ll see there are 2 XXXtreme Spins betting options to choose from:

• One gives 1 guaranteed Starburst Wild every spin, raising the stake by x10.
• The other provides 2 guaranteed Starburst Wilds per spin, pushing the price to 95x the base bet.

If those figures seem steep, remember you can still hit the same number of wilds in the base game—they’re simply less frequent. Your betting approach also nudges RTP slightly, with the return sitting around 96.26-96.45%.

As in the original, the action revolves around Starburst Wilds, which can land on reels 2, 3, or 4. When one appears, it expands to cover all positions on its reel and triggers a respin. Wilds are locked for respins, and if another wild lands, it is also locked and awards an additional respin.

The key new twist is that every Starburst Wild also grants a multiplier of x2, x3, x5, x10, x25, x50, x100, or x150. When multiple wilds land, their multipliers are added together during the respin sequence, and the total applies to any line wins from the triggering spin and any subsequent respins.

A final add-on is the Random Wilds feature. This may trigger at random after a spin or respin, placing 1-3 Starburst Wild symbols onto the middle three reels.

Starburst XXXtreme: Slot Verdict

Putting the two Starburst titles side by side feels like night and day. Initially, the changes aren’t obvious because NetEnt has largely kept the visuals and soundtrack in place. There is a refresh, but the aim wasn’t to rebuild Starburst with modern graphics—it was to create something that speaks to a very different type of player, and to answer anyone suggesting NetEnt has become too tame. On that front, NetEnt has clearly delivered. It’s as if they pulled the old engine out of a Lada and dropped in something Koenigsegg would want under the hood. You can still play at normal stakes and enjoy the familiar starry backdrop, but XXXtreme Spins completely shift the feel, ramping up the pressure on every spin—though they’re expensive, so tread carefully.

Starburst XXXtreme isn’t only about oversized stake options for high rollers. The addition of multipliers—something some readers correctly anticipated—changes the experience from the ground up. If Starburst Wild respins were entertaining before, the knowledge that a combined multiplier of up to 450x can happen adds a whole new layer. It’s not just extra excitement either; the potential payout ceiling is massively higher. NetEnt has set a win cap of 200,000x the bet – achievable in theory through max multipliers, stacked Bars, and respins.

Triple ‘X’ comes with certain associations, and they may not be the most fitting letters for a slot title, but it’s certainly not misleading. Starburst XXXtreme genuinely earns the “extreme” label in multiple ways. While it still carries the spirit of the original, this version is aimed at a very different gambling mindset than the gentle, low-volatility, “first steps into online slots” feel of the classic. Getting the full XXXtreme experience isn’t cheap, but for players who want a tougher ride, it offers a fresh way to enjoy an old favourite.
