Starburst is a five-reel, three-row slot from NetEnt featuring ten paylines that pay in both directions, meaning wins occur from left-to-right and right-to-left. It is commonly described as low volatility and listed at around 96% return to player. Its single feature is the expanding Starburst Wild on the centre reels, which locks in place and gives respins. No scatter and no free-spins round exist. A free play-for-fun demo is available online if you wish to see it in action before staking money.
That is the general overview. This guide on Starburst RTP, Hit Frequency & Max Win Explained UK looks at the source most reviews skip — NetEnt's own game page — to show you what the provider actually states, what it omits, and how the stake cap in the UK affects your betting options.
The provider's published odds
Three statistics are listed on NetEnt's official Starburst page that you should keep in mind:
- RTP: 96.08%
- Hit frequency: 23.00%
- Maximum payout: 800x bet
Almost no review mentions the hit frequency. With a rate of 23.00%, roughly one in four spins results in a return — regardless of how small the win is. This figure is a long-run average calculated over millions of spins, rather than a guarantee for your next session. The last spin does not affect the next one. A 23% hit rate doesn't mean you'll win every fourth spin exactly; it means about a quarter of spins pay over a very long run.
Viewing these figures as long-run tendencies is helpful. An RTP of 96.08% means the game is designed to pay back around £96.08 for every £100 staked over its lifetime — which is again an average over a massive number of spins, not your afternoon.
What NetEnt does not publish
This is just as important as the data provided. NetEnt's page keeps the volatility section blank. This means the "low volatility" label repeated everywhere is the opinion of reviewers and affiliates, rather than a formal rating from the game's creators. While it's a fair description — meaning no massive bonus jumps and small, frequent wins — you should view it as an opinion, not a fact.
NetEnt also provides no bonus trigger rate or free-spins rate and no "1 in N" probability for the maximum win. Any site claiming to know your odds of hitting 800x, or how often the respin feature "should" trigger, is using a number that didn't come from the provider. A "1 in N" statistic would show that a result occurs, on average, once every N spins over a long period — which would be helpful if it were available, but it isn't for Starburst. The 23.00% hit frequency is the sole odds-based figure NetEnt gives.
Is the max win 250x, 500x or 800x?
Reviews give three different answers, which is why players get confused.
- The Bar, which is the top symbol in the paytable, gives 250x the line bet for five consecutive symbols — meaning 250x is the largest payout for a single line.
- A screen filled with Wilds or Bars can result in 250x in both directions since wins pay both ways, and that is how the 500x figure is reached.
- 50,000 coins is another figure you'll see, which is a legacy coin-denomination method instead of a multiplier of your stake.
The definitive figure is NetEnt's: 800x bet. One casino licensed in the UK lists the max win as 500x stake on its page, which shows a configured build instead of the NetEnt default. The provider's own page is the correct source when figures conflict.
The RTP your casino runs may not be 96.08%
There is a catch. While NetEnt's default is 96.08%, operators can use configured versions. One casino licensed in Great Britain lists Starburst at 94.05%, which is a reduced, lower build. Sources dispute whether NetEnt provides several RTP versions (some claim a range from the standard 96.08% down to around 90.05%) or if 96.08% is used everywhere.
The simple practical fix is this: check the in-game info panel to see the version you are playing. Regardless of what a review states, the number found there is the one that applies to your spins.
Stakes and the UK stake cap
A wagering range from €0.10 to €100.00 is listed on NetEnt's page. This maximum does not apply in Great Britain. In Great Britain, online slots are lawful if an operator has a remote casino licence from the Gambling Commission, and these games now have a statutory stake limit for every game cycle:
| Player age | Maximum stake per spin |
|---|---|
| 25 and over | £5 (live 9 April 2025) |
| 18 to 24 | £2 (live 21 May 2025) |
So, you can't play a £100 spin on Starburst in the UK. Statutory limits didn't exist before these rules, and certain games allowed stakes of up to £500 per 2.5-second cycle. These restrictions target online slots specifically, rather than blackjack or roulette. Decide on a budget you are comfortable with and stick to it.
How the respin feature works
Starburst Wilds land on the centre reels (2, 3 and 4), filling the entire reel and acting as a substitute for every paying symbol, which also starts a respin. If a new wild appears during a respin, the process repeats, up to three respins in total. There are no free spins and no scatters, so these are the only bonus features in the game.
One final point to clarify: NetEnt lists the launch date as 23 January 2012. While one review suggests November 2014, the date from the provider is the reliable one.
