Starburst XXXtreme slot review (Netent)

Besides, the slot doesn’t have much of what we demand nowadays, such as more volatility, more win potential, and more features. Starburst XXXtreme is radically different! It’s indeed extreme. The win potential is revolutionary, insane, blistering, whatever you want to name it. The maximum payout is capped at 200,000x the bet.

Starburst XXXtreme – the slot name says it all

I guess everyone knows and has played Starburst. It’s the most famous and most played slot ever, together with Play’n GO’s Book of Dead.

Starburst was released in 2012 and looked, especially for that time, futuristic and spectacular. However, today in 2021, it feels a bit outdated.

It is even higher than Nolimit City’s San Quentin xWays (150,000x) or Pragmatic Play’s Peking Luck (180,000x).

In fact, this slot tops the list of the slots with the highest win potential, alongside Electric Elephant’s Super Boost (200,000x)!

Let’s cut the riffraff and tell you more about the gameplay!


Number of paylines: 9 paylines (pays from left to right)

RTP and variance: 96.26% to 96.45%

Maximum win: 200,000x

Betting range: Not yet known

Bonus features: XXXtreme spins

Casino Hipster verdict: Not just hot, but EXTREMELY HOT! What a win potential! What a thrill to play!

Gameplay and Features

The game has a 5×3 setup and has 9 paylines. Unlike Starburst, you only win from left to right, rather than from both ways.

We have the familiar BARs and Sevens as the two most lucrative symbols, and these payout 50x and 20x for a 5-of-a-kind.  The lows are the five gems.

The Wild symbols with multipliers up to 150x

The Wild symbols are the famous Starburst stars. The wilds appear on reels 2, 3 and/or 4 and come stacked (three wilds on the entire reel).

If you manage to spin at least one reel with Wilds, you gain one additional free re-spin.

What’s different is that the wilds award a random multiplier of 2x, 3x, 5x, 10x, 25x, 50x, 100x or even 150x!

If you get Wilds on reels 2, 3 and 4, you can have a multiplier of at most 450x (if all the three reels have multipliers of 150x each).

The XXXtreme spins

If you’re impatient and if you want to increase your chances to win big, you can. It comes with a price tag, though.

  • If you pay 10x, you get a guaranteed Starburst Wild-Symbol per Spin.
  • If you pay 95x, you get two guaranteed Starburst Wild-Symbol per Spin.

How do you win big?

The recipe is to land the Starburst Wilds on reels 2, 3 and 4, ideally with the 150x multiplier. That gets you a total multiplier of 450x.

If you combine that with BAR symbols on reels 1 and 5, it’s checkout!

A five-of-a-kind of BAR symbols yields 50x, and you have 9 paylines. So that equates to 450x as well!

450x multiplied by 450x gets you 202,500x. Bear in mind that the max is capped at 200,000x.

Starburst XXXtreme slot: the payout rate (RTP) is 96.26% to 96.45%

The RTP of Starburst XXXtreme varies between 96.26% and 96.45%. The good news is that it’s higher than Starburst’s 96.09%.

Starburst XXXtreme slot: the variance (volatility) is EXTREMELY HIGH

I guess that doesn’t come as a surprise, given the incredible win potential!
