What is Starburst?
Starburst is a NetEnt slot released in 2012 with five reels, three rows and ten paylines that pay in both directions. Its defining mechanic is the Starburst Wild: when it lands, it expands to cover its reel and starts a respin.
That is the whole point of the original game. The rules are easy to follow and the main change to a regular spin is visible on the reels, rather than being hidden in a long bonus menu. This guide covers the original Starburst, not Starburst XXXtreme or Starburst Galaxy. Similar titles and artwork do not make their RTPs, volatility or maximum payouts interchangeable.
What is Starburst’s RTP?
Current official pages do not publish one identical figure. Evolution’s Starburst game page lists 96.09% RTP and low/mid volatility. NetEnt’s current product page lists 96.08% RTP, a 23% hit frequency and an 800× maximum payout. Both pages identify the game as Starburst by NetEnt, but neither establishes the configuration inside a particular Great Britain operator’s game client.
The practical answer is to read the information screen in the exact version offered to you. RTP is a theoretical figure based on a large number of game cycles. It does not predict a session or tell you what will happen after a deposit. Read theoretical and actual RTP explained for the difference between a designed percentage and a result.
Starburst in Great Britain: availability and version checks
SlotsUnpacked has not verified a current operator list for Starburst. A provider listing does not establish which Great Britain operator currently offers the original game, or the RTP, stake range and rules loaded in its client.
Before choosing an operator, confirm the exact title, open its information screen and check the displayed RTP and rules. In Great Britain, the maximum online-slots stake per game cycle is £2 for adults aged 18 to 24 and £5 for adults aged 25 and over. Those are legal ceilings, not suggested stakes. See the Gambling Commission’s stake-limit guidance.
How Starburst works
Starburst uses a 5×3 grid and ten fixed paylines. A qualifying symbol combination can pay from left to right or right to left. That two-way pay structure is one of the reasons the game feels straightforward: the payline rules do not ask the reader to track a separate direction for every result.
The base game carries most of the design. There is not a complicated sequence of collectable meters, modifiers or separate feature choices to learn before the core mechanic makes sense. A reader looking for a simple slot structure with one recognisable changing event may see that as the appeal. Someone looking for a layered free-spin round, escalating multipliers or several base-game modifiers is looking for a different sort of game.
How the Starburst Wild and respin work
The defining event has three visible parts: the Wild lands, expands to cover its reel and triggers a respin.
Open each step to see the explanation. These are schematic illustrations, not game screenshots or a simulated result.
Genuine Starburst game imagery showing the expanded Wild reel. Operator versions can differ.
1 · A Starburst Wild lands
The Starburst Wild is the event that activates the original game’s signature mechanic.
2 · The Wild expands across its reel
The Wild expands to cover its reel and substitutes for paying symbols. The diagram explains the rule; it does not reproduce a game reel.
3 · The expanded Wild triggers a respin
A respin follows with the expanded Wild still providing its substitution effect. A respin does not guarantee a prize.
The mechanic does not predict a session’s outcome. Check the information screen in the exact version offered by an operator.
When the Starburst Wild lands, it expands to cover the reel and triggers a respin. NetEnt says the expanded Wild substitutes for paying symbols. The respin gives the reels another outcome with the expanded Wild still providing its substitution effect.
This is why Starburst has such a clear identity. The feature is not a separate black box. You can see the Wild fill the reel, then see why the following respin matters. It changes the payline picture without asking the player to work through a complicated ruleset.
The corresponding trade-off is simple too. Much of the game’s personality sits in that Wild-and-respin event. If it does not appeal, the rest of the game is deliberately pared back. That is a design preference, not a flaw, and it is more useful than treating a simple game as automatically suitable for everybody.
Does Starburst have free spins?
The current official descriptions emphasise respins triggered by the expanding Wild. They do not describe the original Starburst as a conventional scatter-triggered free-spin round. Keep that in-game mechanic separate from a casino’s “free spins” promotion, which has separate eligibility and game-contribution terms.
What kind of slot is Starburst?
Starburst is a mechanically simple, base-game-led slot. Its moving parts are the two-way paylines, the expanding Wild and the respin. That makes it easy to identify and explain, particularly for somebody comparing it with newer games that put most of their activity inside a multi-stage bonus round.
Evolution currently labels its version low/mid volatility. That is provider-stated information about the listed game, not a prediction of a particular player’s results. Volatility describes the spread of outcomes over time. It cannot say when a feature will land or whether a short session will finish up or down.
Practical checks for an operator’s version
- Operator and licenceCheck the operator’s legal entity and website domain against the Gambling Commission’s public register.
- Exact original gameConfirm the library lists the original Starburst rather than Starburst XXXtreme or Starburst Galaxy.
- RTP and deployed rulesOpen the game information and record the RTP and rules shown for that operator deployment.
- Offer eligibilityIf an offer affects the decision, read its eligibility, game contribution, exclusions and significant terms.
Other Starburst questions
What is the difference between Starburst and Starburst XXXtreme?
They are separate NetEnt games. NetEnt describes Starburst XXXtreme as a high-volatility version with Random Wilds and a different feature set. Do not carry the original Starburst’s figures or rules across to it.
Does the expanding Wild guarantee a winning respin?
No. The feature describes how the Wild expands and when a respin is triggered. It does not guarantee that a result will recover previous losses or return more than was staked.
Can the RTP tell me what I will get back?
No. RTP is a long-run mathematical property of a configured game. It cannot predict an individual spin, session or future result.

Sources and scope
Provider material and Great Britain stake-limit guidance reviewed: 29 September 2026. This is a desk-based source review, not first-hand game testing. No operator’s live game client, current availability or offer was verified for this page.
NetEnt’s Starburst product page supports its listed release date, 5×3 format, ten lines, 96.08% RTP, 23% hit frequency, 800× maximum payout and expanding-Wild/respin description. Evolution’s Starburst page supports the NetEnt attribution, 2012 release year, 5×3 grid, ten both-way paylines, low/mid volatility and 96.09% RTP. The figures differ slightly, so this page does not treat either as a universal operator configuration.
