Starburst XXXtreme Slot Review

Hannah Hendricks
Last updated: September 20, 2021

Starburst slot has been knocking around for about a decade now. It's a first-generation Netent slot that was released in 2013 and has stood the test of time. Until now, that is. Whilst Starburst slot is still loved by many casino players around the world and is the go-to game for many free spins casino offers, the game has now gained a younger sibling.

Starburst XXXtreme Slot Introduction

The new Starburst XXXTreme slot was launched in July 2021 and appears to be a lot more ferocious and dramatic than its predecessor. In our new Starburst XXXtreme Slot review, we'll be seeing exactly what this game is all about, why Netent have, after ten years, decided to make a newer version of it, and we'll be taking a look at its in-game features, mechanics and maths. Lastly, as huge slot fans as we are, our slot reviews are unbiased as they come - so we'll be giving you our honest verdict as well.

Whilst the original Starburst slot game is still immensely popular for some, it's got a little dated for others. Netent is a company that's is known to move with the times and Starburst XXXtreme is their way of keeping their flagship slot brand alive. Visually, Starburst XXXtreme uses the same colourful wilds, twinkling gems and futuristic studio sounds that came with Starburst numero uno. However, in the latest version, the background is red and a bit more severe-looking. The soundtrack played a major role in the original Starburst so it's good to that that there's no difference in the Starburst XXXTreme slot. The audio still offers the underlying synth-wave ambient feel, even though the game has geared up a notch from the first.

Unsurprisingly, Starburst XXXtreme is a highly volatile slot game. In the past couple of years, there's been a greater demand for higher volatility slots with more rewarding payouts. Many slot players are looking for faster-paced, higher bet = higher reward type games. And Starburst XXXtreme slot is Netents new entry!   

How To Play Starburst XXXtreme Slot

To play Starburst XXXtrem Slot, you'll first need to find a safe online casino that offers the game. If you're looking to try a new casino and bag a new welcome bonus offer to play Starburst XXXtreme Slot, make sure you check our recommended best Starburst XXXtreme casinos below. They've each been handpicked for their reliability qualities, fair bonuses and overall game choice. Not all casinos offer this game, however, which is why we've done the groundwork for you and cherry-picked a handful of safe and secure casino sites that have the game in their libraries.

Bet levels range from 10p to £50 per spin. To set them, simply click on the coins icon and then choose from the various bet levels shown. For the paytable of the game, click on the "i" icon. Payout amounts are shown in cash and are relative to your current stake level. Once you're all set and ready for your session - it's time to hit spin in the middle of the screen and away you go.

Starburst XXXtreme Slot Features

Netent has unquestionably spiced things up with Starburst XXXtreme. The game is played with a total of 5 reels, 3 rows and 9 fixed paylines. Fundamentally, the gameplay hasn't changed too much when comparing to the original but there are some obvious new features that we will get to in a moment. To start with, the Starburst XXXtreme slot doesn't pay both ways, however, and there's an eagerly-awaited addition of a Starburst XXXTreme spins feature. The iconic Starburst Wilds remain a firm feature too:

Starburst Wilds: These spangly little gems are depicted by a rainbow star symbol (the iconic Starburst star that is) and are pretty important to the game. Starburst Wilds are designed to expand and fill the entire reel, calculate any wins and then award a respin. What's more, Starburst Wilds will lock into place for the respin, with subsequent Starburst Wilds will do the same. If you also manage to create several expanding wilds with multipliers, then their multipliers will be summed together and then applied to your win total.

Random Wilds: Another exciting feature that's a new addition to the new Starburst game is the Random Wilds feature. These Wilds are randomly activated (as if you couldn't guess) after a spin or a Re-Spin. 1 to 3 Starburst Wilds will be added to the reels, along with a random multiplier between 2x and 150x your stake. This feature will once again trigger the Starburst Wilds feature, leading you to bigger wins too.

Starburst XXXtreme Spins (Not For UK): The Starburst XXXtreme spins is where the spiciness comes into play. It's an optional feature that gives you the choice to pay a premium bet in exchange for 1, or 2 guaranteed Starburst wild symbols on reels 2, 3 or 4 (which is where the higher payouts can be found). At this stage, you have the following two options available to you:

  • Option 1: Pay x10 your stake for one guaranteed Starburst Wild per spin
  • Option 2: Pay x95 your stake for two guaranteed Starburst Wild per spin

XXXtreme spins work exactly as they do in the base game. When the Wild symbol lands on the reels, it'll expand, add a multiplier (1-150x) and then pay out any winnings. It will then continue with a free re-spin, where the wild reel will stick on the reel. If you happen to land more wild symbols during the re-spin feature, the same thing will happen all over again, until there are no more winning spins to be had. 

Note for UK Players: Unfortunately, if you're playing the Starburst XXXTreme Slot game in the UK, you won't be able to play the XXXtreme spins feature. This is due to UK Gambling Commission enforced regulations restricting "gamble features" in online slot games. You will still be able to enjoy the new Starburst game, which may be a fresh experience from the decade older game, but you won't be able to partake in the XXXtreme spins feature.

Volatility & RTP %

As mentioned, Starburst XXXTreme is a highly volatile game and comes with an RTP of 96.26%.  When betting with the XXXtreme spins feature,  the game RTP % increases slightly to 96.45%. This RTP % is fairly average for a Netent slot and can be considered a medium - high paying slot game. What's more, the Starburst XXXTreme slot has an average hit frequency of 1 in 5 spins.

Maximum Win Potential & Jackpot

Starburst XXXTreme slot doesn't have a progressive jackpot or any other jackpot to show off about, however, there is still some huge win potential when you line up the respins on the XXXtreme spins feature. The maximum win on Starburst XXXtreme slot is a whopping 200,000X your bet which is a pretty decent amount and is possible with a mixture of max- multipliers, stacked Bars symbols, and Wild respins. For those who like to compare, the original Starburst game offers an x500 your bet maximum win.

Starburst XXXTreme Mobile Slot

These days, Slot game companies focus on their mobile slots over their desktop games any day of the week. This is because so many casino and slots players opt to play on mobile either on their phone or tablet 90% of the time. That's not to say that the Starburst XXXtreme slot isn't good on desktop - of course, it is. But Starburst XXXTreme mobile slot looks sensational and works like a dream on a mobile screen. But then, what Netent mobile slot doesn't? It doesn't matter which device or platform you opt to play this game on, you will be able to play instantly in your mobile web browser at any number of UK mobile casino sites.

Starburst XXXtreme Slot Review Verdict

The majority of the team here at are based in the UK so we're a bit miffed that a game as notorious as Starburst has been re-done with a feature that cannot be fully enjoyed in the UK (The XXXTreme spins feature). Whilst that's not Netent fault (it's the rules of the UKGC which must be respected) it's a shame. For those outside the UK, you can enjoy this game in full throttle mode, if you like slot gamble features that is.

Starburst XXXtreme is indeed extreme in many ways, mainly because it's much more provocative than the chilled original, which was and still is a slot that's perfect for beginners or those who like lower variance ‘easy’ games. Exploring everything Starburst XXXtreme slot offers can become quite spenny though, but if you're up for the challenge and you have the bankroll to try out a new take on an old gem, then this might be a new game for you. Lastly, Starburst XXXtreme's 96.26% RTP rate does afford favourable gameplay for those who don't go all out on the XXXtreme spins which is also good for us. In a nutshell; if you want to give Starburst slot version 0.2021 a go, why not try out the newest version at our recommended UK casinos below?

The following casino sites are those which have been vetted and approved by our team as being safe, trustworthy and fair online casinos. They also each offer a wide range of slots, including Netent's Starburst XXXtreme slot. Choose a new casino with peace of mind that it's legit and has your interests at heart.

Starburst XXXTreme Slot FAQ's

We strived to cover the most critical points in our Starburst XXXtreme Slot review above, though, we've also added some FAQs about the new Starburst slot below.
