The Starburst slot is a 5 reel, 10 payline game from NetEnt which is playable from 10p a spin on all devices, including mobiles. This is NetEnt’s most popular slot and the most popular online slot ever. Starburst has an arcade feel to it and is entirely based on Starburst Wilds. These wilds appear on the 3 middle reels only and can expand to give you up to 3 re-spins with wild reels to give you astronomical wins. Simple in terms of gameplay, it’s mesmerising and gained cult status amongst slot players. Find out why from our Starburst slot review.

Starburst Slot Details & Wager Limits

Reels/Paylines: 5 reels + 10 paylines

Stakes Range: 10p to £100 per spin

Max Win: 500 x stake per spin

The Starburst slot game comes with 5 reels, 3 rows and 10 paylines. With 10 fixed paylines in play, you can spin away from just 10p a spin to as much as much as £100 per spin. Starburst comes with win both ways technology. This means you can form winning combinations by getting 3, 4 or 5 matching symbols on adjacent reels beginning from reel 1 or reel 5.

You can also select the Autoplay option when playing Starburst. You can choose from 10, 25, 50, 100, 250, 500, 750 or 1,000 spins. If you click on the Advanced settings link, you can opt to stop Autoplay on any win, if a single win exceeds a certain amount, if your balance increases or decreases by a chosen amount. This allows you play more responsibly.

When it comes to volatility, Starburst is in the low to medium variance bracket. This means you should get plenty of wins frequently but of the smaller kind. In fact, 22.65% of spins will result in a winning combination (this is known as the Hit Frequency). The max win per spin/re-spin is 500 x stake.

Starburst RTP %

RTP: 96.09%

The Starburst RTP is 96.09%. This pretty in the middle for an online slot game. This means, in theory, that every £100 you spin on the Starburst slot will result in £96.09 being won back. Every spin is subject to a Random Number Generator so you could lose your entire bankroll or win the maximum payout on every spin. It’s down to luck what happens. The RTP % is an average across spins from all players within a predetermined timeframe (normally 1 year).

Theme – cosmic feel

Theme: Outer Space

High Value Symbol: BAR Sphere

Compatibility: Mobile, Tablet, Desktop


The Starburst slot machine is visually beautiful and is set in outer space. What makes it stand out is the rich soundtrack giving it a cosmic feel to it. Released in 2012, the graphics and animations are high definition and still look as good as newer released slots. Developer NetEnt has revamped the game a few times since it’s initial release.

When you get a winning combination, you’ll see arcade-like light effects with flashing text and electrifying sounds. This stands out on a dark background. The soundtrack is electric but quite calming and relaxing. It builds up when you form a winning combination.

Fast paced, symbols include 5 different lit gems as well as a 7 sphere and the BAR sphere. Here’s what each symbol offers payouts wise:

Symbol(s) Payouts
starburst-slot-purple-gem-symbolPurple Gem 3, 4 or 5 = 0.5, 1 or 2.5 x stake
starburst-slot-blue-gem-symbolBlue Gem 3, 4 or 5 = 0.5, 1 or 2.5 x stake
starburst-slot-orange-gem-symbolOrange Gem 3, 4 or 5 = 0.7, 1.5 or 4 x stake
starburst-slot-green-gem-symbolGreen Gem 3, 4 or 5 = 0.8, 2 or 5 x stake
starburst-symbol-yellow-gem-symbolYellow Gem 3, 4 or 5 = 1, 2.5 or 6 x stake
starburst-slot-seven-sphere-symbol7 Sphere 3, 4 or 5 = 2.5, 6 or 12 x stake
starburst-slot-bar-sphere-symbolBAR Sphere 3, 4 or 5 = 5, 20 or 25 x stake

Remember that Starburst is a win both ways slot. If you were to fill the reels with BAR sphere symbols, you wouldn’t win 250 times your stake as such. As wins are formed from left to right and right to left, a screen full of Bar symbols would result in a 500 x stake win.

The most important symbol is the Starburst wild. Only appearing on the 3 middle reels (reels 2, 3 and/or 4), it will substitute for all symbols mentioned above. It will replace symbols to give you their corresponding payout – i.e. 3 Bar symbols and 1 Starburst wild on a payline will result in a 4 of a kind Bar win (20 x stake).

Starburst Mobile Slot


Despite being released in 2012, the Starburst slot still holds its own when it comes to design. It can also be played on desktop, mobile and tablet devices that use iOS, Android or Windows operating systems. A major reason for its popularity is the mobile version. The simple 5×3 layout works well on smartphones.

Starburst Bonus Features

The Starburst slot game comes with just the 1 bonus feature. Whilst it doesn’t have a traditional free spins feature, Starburst wilds will expand to give you wild reels and subsequent re-spins that can lead to 3 wild reels.

Starburst Wilds feature


There’s no Free Spins feature as such but Starburst focuses on the Starburst Wild symbol. Substituting for all symbols, it only appears on reels 2, 3 and 4. When 1 of them appears on any of the 3 middle reels, you will trigger the Starburst Wilds feature.

The Starburst Wild then expands over the entire reel to give you a wild reel. That wild reel remains locked in position with a free re-spin awarded. If another Starburst Wild appears, the process is repeated to give you another wild reel and re-spin.

You could fill the 3 middle reels with the expanding Starburst Wild and benefit from a total of 3 re-spins. The feature only ends when no new Starburst Wilds appear during a re-spin. 3 wild reels makes it easier to fill the reels with the high value Bar symbol. Doing this will result in a 500 x stake payout.

Max Win (500 x)


The Starburst slot is a relatively simple game. This is maybe why it’s so popular. It is clearly the most popular online slot ever and is found at most online casinos. With many other slot developers imitating Starburst, none have the same appeal though. It’s a classic among classics and is a shining star within the online slots world.

Variance wise, it’s low with maximum wins of 500 times your stake on each spin or re-spin available. Despite modern innovations from online slots, Starburst has stood the test of time and is still the most popular online slot ever.

Due to it’s overwhelming popularity, NetEnt have released Starburst XXXtreme on the 15th of July 2021. It has the same theme and graphics but has more bonus features. With multipliers combining up to 450x, the max win is 200,000 x your total stake per spin.

If you like Starburst, you should definitely try the Crystal Sun slot by Play ‘n GO which is similar but comes with multipliers than can combine to give wins of 4,000 times your stake on each re-spin.
