Starburst has proven to be one of the most popular slots of all time and NetEnt is back with a sequel in the form of the Starburst XXXtreme slot. Played using 5 reels and 9 paylines, it offers re-spins with expanding wilds once again. NetEnt has embellished that original feature by adding random multipliers of up to 450x into the mix. Multiple stacked wilds see the multipliers added together for even bigger rewards. Another new addition is the Random Wilds feature. Players can also pay a fee of 10x or 95x to activate XXXtreme Spins where you’re guaranteed to land 1 or 2 Starburst Wilds. Does this volatile sequel match up to the smash-hit original? With 200,000 x stake max wins, find out more in our detailed Starburst XXXtreme review.

Starburst XXXtreme Slot RTP, Details & Wager Limits

Reels/Paylines: 5 reels + 9 paylines

Stakes Range: 10p to £50 per spin

RTP: 96.26%

Max Win: 200,000 x stake per spin

The Starburst XXXtreme slot is played with 5 reels, 3 rows and 9 fixed paylines. The original has 5 reels and 10 paylines in case you’re wondering. To create a winning combination, you need to land 3, 4 or 5 matching symbols or wilds from left to right on 1 of those paylines, starting from reel 1.

Stake levels range from between 10p and £50 per spin. Click on the coins icon below the reels then choose from the stake levels shown. Click on the ‘I’ icon to access the paytable. Payout amounts are displayed in cash and relate to your current stake level. It’s nice and easy to follow.

The Starburst XXXtreme RTP is 96.26% which is above the 96% slots standard. The game certainly lives up to its name as far as variance is concerned. This is a highly volatile slot. Expect a win on a fifth of spins as the hit frequency rate is 20%.

High risks can deliver potentially big rewards with the maximum win here coming in at a whopping 200,000 x your total stake per spin. This makes Starburst XXXtreme a high payout slot.

Theme – a super sharp, futuristic sci-fi sequel

Theme: Outer Space

High Value Symbol: BAR Sphere

Compatibility: Mobile, Tablet, Desktop


There was a simple, futuristic, sci-fi feel to the design of the original Starburst and it’s a similar story with the Starburst XXXtreme slot. It’s set in outer space naturally.

Visually almost identical to the original favourite, the electro soundtrack bounces along nicely and is an ideal complement for the visuals. The design here is simple but it comes together very nicely.

With planets and space in the background, the dark reels are made up of 5 brightly coloured gemstone symbols which are joined by a lucky red 7 and a golden BAR. The BAR is the game’s most lucrative symbol, paying 2.5, 5 or 50 x your total stake if you manage to land 3, 4 or 5 of them across a payline.

The rainbow star is the Starburst Wild which is by far this slot’s most important symbol. As well as substituting for the other symbols, it also triggers the Re-Spin feature which I’ll look at below. Here are all the symbols you’ll come across in Starburst XXXtreme:

Symbol Payouts

starburst-xxxtreme-slot-blue-gemstone-symbolBlue Gemstone 3, 4 or 5 = 0.5, 1 or 3 x stake
starburst-xxxtreme-slot-orange-gemstone-symbolOrange Gemstone 3, 4 or 5 = 0.7, 1.5 or 4 x stake
starburst-xxxtreme-slot-green-gemstone-symbolGreen Gemstone 3, 4 or 5 = 0.8, 2 or 5 x stake

Starburst XXXtreme Mobile


You can blast off into space and play Starburst XXXtreme on all devices including mobiles, tablets, desktop computers and laptops. The minimalist design and the simple gameplay are and ideal combination for play on a handheld device. The Starburst XXXtreme mobile slot certainly doesn’t disappoint.

Starburst XXXtreme Bonus Features

The original Starburst game was a very simple one in terms of features. The core feature is very similar in Starburst XXXtreme but NetEnt has bolted on even more extras to ramp up the action. There’s a total of 3 bonus features to benefit from.

Starburst Wilds feature


The best action in Starburst XXXtreme revolves around the Starburst Wilds feature. Starburst Wilds can land on reels 2, 3 and 4 only and substitutes for all the other symbols in a winning combination.

Whenever a Starburst Wild lands, it expands to fill the whole of that reel. A re-spin then follows with the stacked Starburst Wild locking in position. If another Starburst Wild lands, it too locks in place and another re-spin follows. It’s possible to land a re-spin with all of reels 2, 3 and 4 wild.

The first big difference between Starburst XXXtreme and the original is that Starburst Wilds here can come with multipliers attached. These multipliers are worth 2x, 3x, 5x, 10x, 25x, 50x, 100x or 150x.

Better still, is if you manage to land more than 1 Starburst Wild multiplier in the same winning combination. When that happens, the value of the multipliers is combined up to 450x to deliver an even bigger payout boost.

Random Wilds feature

The Random Wilds feature can trigger at random after a spin or re-spin. Between 1 and 3 Starburst Wilds are added to the reels, complete with a random multiplier value of between 2x and 150x. 3 Starburst Wilds can lead to a massive 450x multiplier overall.

XXXtreme Spins feature


Players will have the chance to pay a fee and purchase spins which guarantee that a Starburst Wild lands. Known as the XXXtreme Spins feature, you have 2 options:

10 x stake 1 Starburst Wild is guaranteed to land
95 x stake 2 Starburst Wilds are guaranteed to land

The XXXtreme Spins will remain live until you deactivate them. Click on the box in the bottom left-hand corner of the screen to activate or deactivate the XXXtreme Spins. The RTP increases up to 96.45% when using this feature. However, it’s not available in the UK due to Gambling Commission regulations.

Max Win (200,000 x)


The original Starburst is one of the most popular slots of all time so NetEnt had a lot to live up to with the launch of the Starburst XXXtreme slot. No pressure then. The design is sharper than the original though.

Thankfully, they’ve done the job very nicely indeed, taking the core gameplay elements from the original and ramping up the action with extras like multipliers.

With multipliers up to 450x available in the re-spins, the win potential is now huge. The original game offered 500 x stake max wins with the XXXtreme version paying up to 200,000 x your total stake per re-spin. The addition of the Random Wilds feature is a nice little extra which brings Starburst Wilds and multipliers into play.

The XXXtreme Spins feature is suited to those who want to guaranteed Starburst Wilds landing but be prepared to be disappointed as most wins will be below the fee you pay.

The triple X name could make you think of other things so NetEnt should have called it Starburst Extreme or Starburst Xtreme. However, this sequel has been highly anticipated and NetEnt has created more than a worthy successor to the classic sci-fi adventure.

If you want big max win potential, Nolimit City’s San Quentin offers 150,000 x stake payouts on each spin. Theme and gameplay wise, it has more going on than Starburst XXXtreme.

  • Takes original Starburst slot to a whole different level
  • 200,000 x stake max wins per spin
  • Stays true to the iconic original game
  • a Free Spins feature would have been ideal
