Starburst™ RTP, Free Demo and Max Win

Starburst RTP and key numbers

Facts checked on 6 November 2026 against NetEnt's game page and independent reviews. Casinos can run a lower RTP setting, so open the game info screen and check the figure before you play.

How Starburst works

Starburst came out in 2012 and has barely changed since. You get 5 reels, 3 rows and 10 fixed paylines set in space, with coloured gems, a bar and a 7 as the symbols. The bar is the top paying symbol.

The first thing to know is that wins pay both ways. A line pays if it starts on the leftmost reel and runs right, or starts on the rightmost reel and runs left. Only the highest win on each line is paid. In practice this makes the 10 lines play more like 20, which is part of why the game hits so often. The hit rate is about 23%, so roughly one spin in four returns something.

Most of those wins are smaller than your bet. A typical session moves up and down in small steps, with the occasional bar or 7 line pushing the balance up a bit.

Starburst free spins and bonus features

There is no free spins round, no scatter and no bonus game. The whole feature set is one symbol: the Starburst wild.

The wild can land only on reels 2, 3 and 4. When it does, it expands to fill the whole reel, stays in place, and the game gives you a free respin. If another wild lands on a different middle reel during the respin, that reel also expands and you get another respin. With all three middle reels covered you reach the maximum of 3 respins in one go.

Three wild reels on a 5x3 grid with lines that pay both ways is the best setup the game can produce. Every line is then decided by reels 1 and 5, and matching high symbols on the outer reels can pay across many lines at once. That is where the top results come from.

There is no bonus buy, so nothing changes if you play at a casino that bans buys during wagering.

Starburst RTP versions: what to check

NetEnt's own game page lists the RTP as 96.08%, while most reviews give 96.09%. The difference is tiny. What matters more is that NetEnt makes several RTP versions of Starburst and casinos choose which one to run, so the number at your casino can be lower.

Click the menu or the paytable icon in the game and look for the line that states the theoretical return. If it is well below 96%, you are on a reduced setting. Our guide to RTP and volatility explains how much this matters over a long session.

Max win and volatility in practice

Most reviews put the maximum at 500x your stake per spin. NetEnt's own page shows 800x. We use the lower figure. Either way it is a small ceiling by modern standards.

Reviews rate the volatility low, and NetEnt's own card calls it medium. The hit rate backs the low rating: you see frequent small wins and rarely lose a large part of your balance quickly. The flip side is that you also rarely win big.

That profile makes Starburst one of the better games for wagering a bonus. A steady game keeps your balance alive longer, which gives you more chances to finish the playthrough. Use our wagering calculator to see how many spins a bonus needs at your stake.

Playing Starburst with free spins or a bonus

Starburst is probably the most common game in casino free spins promotions. You can compare current deals on our free spins page and check what a deal is worth with the free spins value calculator. Before you claim, read our wagering requirement guide, since the playthrough often decides whether you keep anything.

The usual bonus rules still apply: a max bet per spin, a deadline, and often a cap on what free spins winnings can be converted into. Bonus buy bans do not affect this game. If you want a casino with a big slot lobby for promotions like this, see our Mostbet review.

Similar slots

Twin Spin is another NetEnt classic built around one simple reel feature. Fire Joker from Play'n GO has a similar retro feel and a short feature list. If you want more action from the same studio, Gonzo's Quest adds cascades and free spins. Browse the full list on our NetEnt slots page.

Our verdict on Starburst

Starburst is easy to pick up and it does one thing well: steady play with frequent small wins and the odd respin sequence that lights up the middle reels. The RTP is fine at the top setting, and the low variance makes it a solid pick for clearing bonuses or for players new to slots. If you want big multipliers, free spins rounds or a large max win, look elsewhere. For a relaxed session on a small budget, it still holds up.
