Starburst XXXtreme Online Slot Review

NetEnt updated one of the most successful online slot games in history with their Starburst XXXtreme slots game. It’s a 5-reel, 9-payline game that you can play on PCs, iOS, Android, and Windows mobiles.

Colorful jewels, BARs, and red 7s feature on the reels, along with multi-colored star wild symbols. These award respins and come with random multipliers of up to 150x. Combine the maximum numbers of wilds with multipliers and you can win an eye-watering 200,000x your wager from this game. That’s a colossal 10,000,000.00 at the maximum wager level. The average payback percentage of this high volatility game is 96.26%.

How to Play the Starburst XXXtreme Slot

Launched in 2013, Starburst is not only the biggest slot in the NetEnt range, but quite possibly the most successful from any developer. Many of the elements that make it so popular are carried over to the Starburst XXXtreme online slot, such as the vivid color-scheme, and sci-fi style.

The 5x3 grid of symbols seem to float in space above an alien planet. The graphics are quite retro, and basically unchanged, as clearly, NetEnt realised that if it ain’t broke, don’t fix it. Light sparkles off the blue, orange, green, and purple gems, while the golden BAR and bright red 7 look like planets with something orbiting them.

Away from the imagery, we have a simple set of controls that work perfectly well on desktop and mobile versions of the Starburst XXXtreme slot machine. The button that looks like a little pile of coins unlocks the wagering options, which run from 0.10 to 50.00 per spin. Tap the red circular arrows and once you set a loss limit, the reels spin automatically, while the double arrow button activates a fast-spin feature.

Respins & Other Starburst XXXtreme Slot Features

A colorful star is the wild symbol, which has the power to act as any other if it can complete a win. It only turns up on the middle 3 reels, so isn’t worth anything on its own, but this is the key to unlocking the big wins.

Any time the wild symbol appears, it expands to cover the whole reel, then locks in place as the others respin for free. It gives you a second chance to land a winning combination, and if another wild appears in the respin, this also locks before the remaining 3 reels respin once more. A third and final respin plays out if yet another wild symbols lands again. A random wilds feature can trigger after any spin, and it places 1, 2, or 3 wilds on the middle reels.

All wilds come with random prize multipliers of 2x, 3x, 5x, 10x, 25x, 50x, 100x, or a maximum of 150x.Wins from wilds and respins get increased by the amount shown, but what makes this even more exciting is that the multipliers from 2 or 3 wilds combine together. If you manage to land 3 wilds at once, and each has a 150x multiplier, your win will be 450x the basic value!

Our Starburst XXXtreme Slot Rating

NetEnt have managed to update a classic game without losing anything that made the original so popular. It’s a good-looking slot machine with plenty of color and style.

Of course, wild multipliers won’t hit 150x too often, and landing 3 at the same time will be a rare treat, but you don’t need these massive values to land big prizes.

Respins with every wild symbol make it easier to grab another prize, and a multiplier of at least 2x is often enough to give your bankroll a boost.
