The Starburst slot game is a low-volatility, 243-ways-to-win title developed by NetEnt that pays in both directions — left-to-right and right-to-left — across five reels. Its signature feature is an expanding star wild that triggers up to two free re-spins when it lands on reels 2, 3, or 4.
What Makes the Starburst Slot Game Different from Standard Slots?
Most slots pay only left-to-right. Starburst uses a 243 ways-to-win system, meaning matching symbols on adjacent reels count anywhere on those reels — no fixed paylines to miss. That alone changes how wins accumulate, especially during re-spin sequences.
For a deep look at how the pay system is structured, see Starburst Slot: Inside the 243-Ways Pay System. And for the full rules covering symbols and bet sizes, the Starburst game rules page walks through setup from the beginning.
How Do the Expanding Wilds Work?
When a star wild lands on reel 2, 3, or 4, it expands to fill the entire reel. The reels then re-spin — for free — with that expanded wild held in place. If another wild lands during a re-spin, it also expands and locks, triggering another re-spin. You can get up to two re-spins total per wild sequence.
The full mechanics, including what happens when two wilds land simultaneously, are covered in How Expanding Wilds and Re-Spins Work in Starburst.
