Starburst Slot Review

Starburst Slot by NetEnt is arguably the most famous online slot ever made. Released in 2012, this 5x3 jewel-themed game has become the default slot that casinos hand out free spins on — and there's a reason for that. With 10 paylines, an RTP of 96.09%, and low volatility, it's designed to keep you spinning. Try the free demo above before putting real money on the line.

Here's the uncomfortable truth about Starburst: most players have never chosen to play it. They've been funneled into it through free spins bonus promotions. And that's by design. Casinos love giving away Starburst spins because the 500x max win means they're unlikely to pay out anything catastrophic. If you're chasing life-changing multipliers, close this tab now. Starburst isn't that game. But if you want a clean, low-stress session where your balance doesn't crater in 40 spins, it still holds up remarkably well after more than a decade. Think of it as the opposite of Reactoonz — no cluster chaos, no cascading madness. It's closer to Fluffy Favourites in spirit: simple mechanics, gentle variance, broad appeal. Just with shinier gems.

Starburst uses a win-both-ways mechanic across its 10 paylines, meaning matching symbols pay from left to right AND right to left. This effectively doubles your chances on every spin compared to a standard left-to-right setup. The game has no traditional free spins round, no pick-and-click bonus, no progressive jackpot. What it does have is the Starburst Wild — a rainbow-coloured expanding wild that appears only on reels 2, 3, and 4.

When a Starburst Wild lands, it expands to cover the entire reel and triggers a re-spin. If another wild lands during that re-spin, it also expands and you get another re-spin. You can chain up to three expanding wilds for a maximum of three re-spins. That's where the 500x max win lives — three reels locked wild with the right symbols flanking them. In practice, we rarely saw more than two wilds chain together. Single wilds were common, paying anywhere from 2x to 30x our bet. The math is honest: low volatility means small, frequent wins that keep your balance gently bobbing rather than plunging.

Technically, Starburst doesn't have a traditional bonus round. The expanding wild re-spin feature IS the bonus. When a Starburst Wild symbol lands on reels 2, 3, or 4, it expands to fill the entire reel, holds in place, and awards a free re-spin. Additional wilds during re-spins repeat the process, up to a maximum of three re-spins.

In our testing, we triggered at least one expanding wild roughly every 8-12 spins. That's frequent — you're never waiting long. However, the payouts from single-wild triggers were modest, typically 3x to 15x. Double-wild triggers happened approximately every 50-70 spins and paid 15x to 80x. The elusive triple-wild? We didn't hit one in 200 spins. The theoretical max from this feature is 500x your total bet, but realistically you'll see 10x-40x from most wild triggers.

Play if:

• You have a bankroll of £20-£50 and want 100+ spins of entertainment at low stakes
• You're clearing a welcome bonus and need a low-volatility game to grind through wagering requirements
• You prefer knowing roughly what to expect from a session rather than wild swings
• You're new to slots and want something straightforward to learn on

Skip if:

• You need at least 1,000x max win potential to feel engaged
• You want a proper free spins bonus round with multipliers
• You have £500+ and are looking for high-volatility thrills — your money is better elsewhere
• You've already played 10,000 spins of this and are bored (valid)

Starburst is available at virtually every licensed online casino. For UK players, we recommend checking our best slots sites for operators that carry NetEnt's full catalogue.

Our fast payout casinos process withdrawals within hours, not days.

Starburst is the Toyota Corolla of online slots — unglamorous, reliable, and everywhere for a reason. It won't make you rich. The 500x ceiling is genuinely low by modern standards, and the lack of a proper bonus round feels dated in 2024. But for low-stakes grinding, bonus clearing, and gentle entertainment, it remains a perfectly functional game. Just don't mistake familiarity for quality — play it because it suits your goals, not because a casino handed you 20 spins on it.

Responsible Gambling

Starburst's low volatility can create a false sense of security — small, frequent wins might encourage longer sessions than you planned. Always set time and deposit limits before playing. If gambling stops being fun, stop. Visit our responsible gambling page for tools and support, or contact BeGambleAware.org for independent help and advice.
