Starburst XXXtreme slot review

Despite different sibling releases from NetEnt, as well as the treasure trove of Starburst mechanic copycats, Starburst XXXtreme is the first official follow-up game to the timeless classic released all the way back in 2013. While the first release is pretty close to being a perfect game to start off new players on their online casino journey, this sequel is hardly for beginners and casual punters.

The volatility can be pretty brutal, not least compared to the light-hearted original, and the 2 XXXtreme betting options (not for UK players) can easily burn through your bankroll in no-time. Adding random multipliers up to x150 per expanding wild is a very tempting prospect though, and these can combine into insane payouts up to 200,000x your stake. We like that NetEnt is holding nothing back in this release, not least since they’ve been kind of tame lately.

Starburst XXXtreme Slot - Reels Screen

Starburst XXXtreme Features

You can play with 1 of 2 XXXtreme Spins options active if you wish, and this increases the RTP to 96.45 %. The options are as follows:

  • Pay 10x the regular stake for 1 guaranteed Starburst Wild on each spin.
  • Pay 95x the regular stake for 2 guaranteed Starburst Wilds on each spin.

Landing Starburst Wilds is, of course, also possible in the regular base game, and they appear on the 3 middle reels only. Whenever a Starburst Wild lands, it will expand to cover the entire reel, and award a respin. The wild (or wilds) become sticky for the respin, and if you land more wilds the process repeats up to 3 times.

The biggest difference from the original game, is that Starburst Wilds now also dish out random multipliers of 2, x3, x5, x10, x25, x50, x100 or x150. Landing multiple wilds means that the multiplier values are added together up to x450 at the most. The multiplier will boost any line wins from the spin where the first wild landed, and any respins that follow (which also add to the multiplier).

Another “bonus addition” to this follow-up game is the Random Wilds feature. This feature can trigger after any given spin, or respin, and it awards 1 to 3 Starburst Wilds on reels 2, 3 and/or 4. Of course, these wilds also come with a random multiplier up to x150, which can create a combined x450 boost with maximum luck.

The 200 Spins Starburst XXXtreme Experience

We have been looking forward to this release for a while, and it’s a relief to finally get to try the game. We have to say that we’re hardly disappointed, and we had a great time testing Starburst XXXtreme. 200 spins might be enough to get a good first impression, but we will definitely be back for more later. See for yourself how we fared in the brief and edited highlights video below.

Review Summary

The triple-X in ‘XXXtreme’ seems a bit, ehm, “extreme”, perhaps, but at least it’s going to get noticed. The game certainly lives up to the title though, and NetEnt has pretty much taken everything to the extreme opposite polarity in Starburst XXXtreme - well, everything except the audiovisual presentation, which remains very similar to the somewhat dated original.

The eye-popping 200,000x potential is technically possible indeed, and racking up potentially massive multipliers up to x450 from the classic Expanding Sticky Wilds Respins feature is very much a game-changer. The same can be said about the 2 XXXtreme Spins options, and overall this is pretty much everything we hoped for in a follow-up to one of NetEnt's most iconic and timeless releases.


  • 2 XXXtreme Spins betting options
  • Expanding sticky multiplier wild respins
  • Multipliers can combine up to x450
  • Win up to 200,000x your stake


  • XXXtreme Spins not available in the UK

If you appreciate Starburst XXXtreme you should also try:

Starburst - is a great alternative if you need to cool off and/or get grounded after a big win (or loss) on this beast of a follow-up. The low volatility version might not offer all that much in terms of potential, but it offers a good contrast and warm-up to the heavy hitter you’ll be dealing with here.

Slingo Starburst - is the highly entertaining slot/bingo hybrid version of NetEnt’s ever-popular original. Climb the Win Spin ladder by getting slingos, and win symbol-specific Starburst wins. The top-tier features awards up to 3 expanding wild respins, which can lead to payouts up to 1,500x your stake.

Berryburst - is an earlier and “unofficial” Starburst follow-up from NetEnt, and it comes with a cluster pays engine. Wilds expand, lock in place and trigger respins just like in Starburst, but they can land on all 5 reels instead of just the 3 middle reels here. This can lead to payouts up to 1,868x your stake.
