Nearly all Starburst fans used to play a well-known cosmic title from NetEnt at least once. But the previous version of Starburst lacked some action-filled features, so the vendor decided not to let the events develop on their own and created a new variation on 15/07/2021. As a result, Starburst XXXtreme is a blast that strikes the gameplay via a ground-breaking winning limit of 200,000x and appealing parameters to provide this amount. Prepare for extremely high volatility in space and rewards for the most resistant players!

How to Play

When players have an opportunity to visit outer space, there is no time to hesitate. The following guide is what you need to do:

  1. A small button with coins is located on the right and once it’s pushed, players can see the layout of available stakes that stand at €0.10–€50
  2. There is a round button in the middle, which allows players to trigger the reels whenever they are ready
  3. You can change the bet each time you make a new spin, and you can also launch up to 1,000 autospins to play at the same bet
  4. Optionally, players can activate 1 of 2 variations of XXXtreme Spins

The menu panel also has a bunch of additional buttons that can open the paytable, modify the sound effects, and more.

Starburst XXXtreme RTP and Volatility

7.8 
This slot features high volatility and 96.26% RTP.
This cosmic ride is going to be extremely bumpy as each and every spin is super risky because of the high variance. Only the most avid high rollers will appreciate this game style. The RTP of 96.26%, but once gamblers activate XXXtreme Spins, the score is even better as it comes up to 96.45%.

Theme

8.0 

The game’s cosmic theme is similar to the one that was displayed in the previous version of this slot. Sparkling gems of different colours are covering the 5x3 grid, and a galaxy is a place where this grid can be found. Super relaxing music is kept the same that was provided in the first version, so this title oozes nostalgia and makes the old version unbelievably upgraded at the same time.

Of course, all these symbols are covering the grid not only for decoration. Each symbol has its value, and the higher it is, the tougher it is to land the necessary symbols. That’s why purple, blue, orange, green, and yellow gems are landing more often, though their value is also slightly different, and yellow stones are the most profitable as they pay up to 6x. The other symbols are a lucky seven that provides 1.50–20x and BARs are the most attractive as they pay up to 50x. And a well-known symbol of the multicoloured star is a Wild that can land on the middle reels 2 to 4.

Mobile compatibility

Mobile compatibility
Instead of a spacesuit and special astronaut equipment, modern players can simply use mobile phones they use in daily life. Yes, this device is enough to arrange this cosmic adventure, and both operating systems will be good for this, be it iOS or Android. Moreover, Windows phones are also involved, so there are no borders for mobile gambling thanks to NetEnt and HTML5 code the vendor uses.

About NetEnt

NetEnt is a Swedish vendor that is in charge of fascinating titles with themes and options that have no analogs on the iGaming scene. The year when this ‘star’ was born is 1996, so the company boasts deep expertise in both online and offline areas. It has numerous awards for its high-quality products. And these products really deserve all these rewards as titles like Narcos, Divine Fortune Megaways, and Dead or Alive 2 are known all over the world.

Bonus Rounds & Free Spins

7.9 

What is an immersive cosmic machine when its options are limited? In the case of Starburst XXXtreme, the following features are, vice versa, unlimited, due to which, an immersive experience is guaranteed.

Wild Respins

Well-known colourful stars land on reels 2 to 4. They not only serve as Wilds but also substitute for the entire reel and activate a re-spin. Moreover, the symbol awards a random multiplier, which can stand at 2x, 3x, 5x, 10x, 25x, 50x, 100x, and 150x. And if gamblers are lucky to land more than 1 Wild, their multipliers are added to each other to multiply the line win.

Random Wilds

The following feature can be randomly launched after a regular spin or a re-spin. Thanks to it, 1 to 3 Wilds are added to the middle reels.

XXXtreme Spins

Optionally, players can activate XXXtreme Spins, during which, 1 or 2 guaranteed Wilds land per spin. The option is activated for money and its cost is 10x or 95x the bet respectively. All the options of Wilds and the features they launch remain the same. Players can deactivate the option at any time.

Starburst XXXtreme Demo Play

You may have heard that space journeys are super expensive. Perhaps it’s really so, but it can’t be said about the slot that features cosmic options as the demo version is waiting for all customers and is available round the clock. Play Starburst XXXtreme for free on this page and enjoy all its parameters without spending a coin.

Max Win

10 
Super difficult to get yet unbelievably attractive, the slot’s main prize is up to 200,000x the bet.
This paragraph is nearly the most crucial in this article as it’s hard to believe in such a massive win of up to 200,000x. Yet, it’s really the truth and all players who land real-money stakes can hunt for this unbelievable amount. But we should warn you that this prize makes the game super volatile and it’s very difficult for players.

Overall Rating

8.9
NetEnt never stops working on making great games. That’s why a well-known game was upgraded to deliver Starburst XXXtreme, a new variation of a cosmic machine with a whole lot of new features. The main advantage of this cosmic project is its winning score of up to 200,000x the bet, but we don’t recommend newcomers to take such high risks, so estimate your budget and facilities before getting started.
