Can't get enough of NetEnt's classic Starburst game? Starburst XXXtreme is the new and improved version, featuring Random Wilds, Multipliers, and a max win of up to 200,000x.
Starburst XXXtreme looks like a slightly more modern version of the original game. The symbols are sparkling gems in bright colors like blue, yellow, and orange, and the gameplay is smooth, with just a hint of inspiration from older, mechanical slots. The slot is set in space, but the backdrop is very simple: a dark sky with a few stars and no animations.
There's a cosmic theme tune to set the scene. It's a rhythmic drumbeat, overlaid with space-age sound effects, fit for an intergalactic adventure.
Starburst XXXtreme comes with five reels, three rows, and 9 fixed paylines. To win, you'll need to get at least three matching symbols on adjacent reels from left to right, on one of those paylines. Just like you'd see in retro slot games, the highest-paying regular symbols are the bars and the sevens, while the colored gems pay out smaller wins.
The Starburst Wild symbol can appear on reels 2, 3, and 4, and it substitutes for other symbols, to help trigger wins. A Starburst Wild can expand to cover the entire reel and trigger a Respin. During Respins, each reel covered by a Wild locks in place, while the other reels spin. Respins end when no new Wilds appear. Each Wild also awards a random Multiplier, with a value of up to 150x.
The Random Wilds feature can be activated after a spin or a Respin. During this feature, between one and three Starburst Wilds are randomly added to the grid.
The standout feature of Starburst XXXtreme (which the original game doesn't have) is the XXXtreme Spins round – but unfortunately, getting into this round will cost you money. You can spend 10x your bet to guarantee one Starburst Wild symbol, or 95x for two guaranteed Starburst Wild symbols.
Starburst XXXtreme has a Return to Player (RTP) percentage of 96.26% which is a little higher than the average for slot games, which stands at 96%. It's also higher than the main Starburst game, which has an RTP of 96.09%. The volatility of Starburst XXXtreme is high, which generally makes for exciting gameplay, as wins can be quite big, although they're not too frequent.
You can play Starburst XXXtreme for between $/€/£0.10 and $/€/£50 per spin, and the game has a very impressive max win of 200,000x.
The main reason we'd recommend Starburst XXXtreme is the high max win of up to 200,000x. That's certainly not common with slot games, and as this one has high volatility, wins are generally a little bigger than average anyway. The minimum stake amount is low at $/€/£0.10, and the addition of the XXXtreme Spins feature makes this title a big improvement on the original Starburst game. This is definitely one of the best slot sequels we've seen in recent years.
