Starburst

Starburst is NetEnt's most famous creation and arguably the most recognised online slot ever made. Released in 2012, this dazzling space-and-gems slot became a global phenomenon thanks to its simplicity, vibrant visuals and smooth, satisfying gameplay. It is low volatility, pays frequently and is endlessly featured in casino welcome offers, which is why it is often the very first slot a new player ever spins.

The game uses a compact 5x3 grid with 10 paylines and, crucially, a win-both-ways system: matching symbols pay from the leftmost reel to the right and from the rightmost reel to the left. Combined with a low minimum of just three matching symbols for a win, this means payouts land often, keeping the action steady and beginner-friendly rather than tense.

Expanding wilds and re-spins

Starburst has no free-spins round, no bonus buy and no complicated features — and that is precisely its appeal. Its single special mechanic is the Starburst Wild, a multicoloured gem that appears only on reels 2, 3 and 4.

When a Starburst Wild lands, it expands to cover the entire reel and locks in place, then awards a re-spin. If another wild lands during that re-spin, it too expands and locks, triggering a further re-spin — up to three expanding wilds can be active at once. With wilds substituting for every symbol and the win-both-ways system in play, these stacked-wild re-spins are where Starburst delivers its best wins, up to a maximum of 500x your stake.

RTP, volatility and stakes

Starburst runs at a default RTP of 96.09%, with operators occasionally offering other versions. It is a genuinely low-volatility slot, which means wins are frequent but generally small; the 500x maximum is modest by modern standards, but the trade-off is a relaxed, long-lasting session that rarely drains a balance quickly. Stakes are flexible, from 0.10 to 100 per spin, suiting cautious and casual players alike.

Tips and who it's for

Because Starburst is low variance, it is ideal for stretching a bankroll, learning how online slots work, or clearing the wagering requirements on a bonus where it is permitted. There is no strategy to master — simply set a comfortable stake and enjoy the frequent small wins and the anticipation of stacking those expanding wilds. It is the perfect slot for newcomers and for anyone who prefers steady, low-pressure entertainment over the wild swings of high-volatility titles.

Strategy and who should play it

Starburst is the rare modern slot where the best strategy is simply to relax. Its low volatility means wins arrive frequently but stay small, so the experience is about steady, low-pressure entertainment rather than chasing a life-changing payout — the 500x ceiling is modest by design. That profile makes it ideal for three types of player: complete beginners learning how online slots behave, anyone who wants a long, gentle session from a small budget, and bonus players clearing wagering requirements where the game is eligible and counts at a high rate. Because there are no free spins, multipliers to buy or complex decisions, you simply choose a comfortable stake and enjoy the rhythm of the expanding-wild re-spins. As always, confirm the RTP version your casino uses, set a budget before you start, and remember that even a low-volatility slot carries a house edge, so it remains a form of entertainment rather than a reliable way to win.

More than a decade after release, Starburst remains a fixture of casino lobbies and even inspired a sequel, Starburst XXXtreme, with a far higher-risk maths model. The original endures because it does one thing perfectly: simple, beautiful, dependable fun. Try Starburst in free demo mode here, and as always, set a budget and play responsibly.

How Starburst compares

At 96.09%, Starburst sits below the 96.49% median of the 16 slots we have reviewed, on low volatility. Return alone rarely settles the choice, though: volatility and the ceiling decide how that same percentage feels across a session. The table below puts Starburst next to the closest alternatives in our catalogue.

Every figure is the studio's default configuration. Operators are free to run a lower RTP build of many of these games — our guide to RTP explains why that happens and where to check the version you are actually playing.
