Pros and cons of Starburst XXXtreme

Game details of Starburst XXXtreme from NetEnt

The action unfolds on a standard 5-reel, 3-row grid with nine fixed paylines. To form a winning combination, you need three or more matching symbols on adjacent reels from left to right.

You can join this cosmic journey with a minimum bet of just $0.10, playing on desktops, smartphones, or tablets.

Visually, the game remains true to the original, retaining its futuristic design, electronic soundtrack, and space-themed backdrop. Even the symbols are nearly identical: five lower-value gems (yellow, green, orange, blue, and purple) and two high-paying icons—the lucky red seven and the golden BAR.

The golden BAR is the most valuable symbol, awarding up to 50x your total bet for a five-of-a-kind combination.

The rainbow-coloured Starburst Wild is the key to unlocking the game's most exciting features. It substitutes for all symbols and activates the re-spins feature, which we'll explore below.

Starburst wilds, re-spins & multipliers

The signature feature of the game remains the Starburst Wild, which substitutes for all other symbols and appears only on reels two, three, and four.

When a Starburst Wild lands, it expands vertically to cover the entire reel, locks in place, and triggers a re-spin. If another wild appears, the process repeats. You can get up to three re-spins in a row when new wilds appear.

In this upgraded version, each Starburst Wild comes with a random multiplier between 2x and 150x. If multiple Wilds land, their multipliers combine, reaching a staggering 450x.

Random Wilds

This feature activates randomly after any spin or re-spin, adding one to three Starburst Wilds on reels 2-4.

XXXtreme Spins: Bonus buy options

Players can opt to buy guaranteed Starburst Wilds through the XXXtreme Spins feature:

• 10x the bet: Guarantees one Starburst Wild per spin
• 95x the bet: Guarantees two Starburst Wilds per spin

This feature remains active until manually disabled, returning the game to standard spins.

Volatility and RTP of Starburst XXXtreme

NetEnt's Starburst XXXtreme is a high-volatility slot, meaning wins are less frequent but more substantial. We recommend this game to players with a higher bankroll, as it can take time to land a larger win.

The slot's RTP is an impressive 96.26%, making it a competitive choice compared to similar high-risk games.

With big risks come big rewards, and in this case, the top win potential reaches an astonishing 200,000x the total bet per spin.

Our verdict of Starburst XXXtreme

Starburst XXXtreme successfully builds upon the legendary status of its predecessor Starburst while delivering an even more thrilling gameplay experience. NetEnt has taken the excitement to a whole new level—though the graphics and sound remain unchanged, the mechanics have been amplified significantly.

The introduction of random multipliers and the ability to rack up a 450x boost makes this slot a true game-changer. If you enjoyed Starburst’s wild re-spins before, the added potential for astronomical wins makes this sequel a must-try.

With a massive top win of 200,000x the bet, achieved through a combination of stacked BAR symbols, re-spins, and max multipliers, the possibilities are out of this world.

While the high volatility means big swings, the game remains engaging thanks to a well-balanced math model and dynamic features. If you love slots with a higher volatility, also check out NetEnt's slot Starburst Galaxy!
