Starburst

The numbers first

Starburst runs on 5 reels and 3 rows with 10 paylines, and NetEnt’s official game page puts its return to player at 96.08% and its top payout at 800x the stake. The studio also quotes a hit frequency of 23%. Its page has a space for volatility, but nothing is filled in, so no volatility rating is published. Taken as a set, these figures suggest a game designed around fairly regular, mostly small returns: an RTP in ordinary territory, a ceiling that is low by current standards and a win on a little under a quarter of spins over the long term. That reading is drawn from the published numbers, not from any risk label NetEnt has attached.

Specification

NetEnt quotes its stake range in euros. The SlotSpecs demo uses virtual coins, so changing the stake simply rescales the figures on screen.

One wild, one respin: the sequence in order

Everything special in Starburst starts with the Starburst Wild. There is no scatter to collect and no meter to fill. Here is how NetEnt describes the feature unfolding.

• The reels stop and a Starburst Wild is showing somewhere on the grid.
• The wild grows to fill its whole reel, turning all three positions on that reel wild.
• A reel that is wild from top to bottom sits on every one of the 10 paylines, because each line has to pass through one of its three positions.
• The wild substitutes for every paying symbol, so any line that only lacked that reel to complete a match now counts.
• The spin’s wins are settled, and the wild then sets off a respin.

The key point is reach. A normal symbol affects only the lines it happens to sit on, while an expanded wild affects all ten at once. A screen of scattered near-misses can become several line wins from one symbol arriving on the right reel, which is where most of the game’s lively moments come from.

The feature lives inside ordinary play. There is no separate bonus screen to unlock, no build-up across spins and no menu option to jump straight to it; NetEnt describes no feature buy, so the only way in is for a wild to land.

The studio’s summary leaves some detail out. It does not say whether the expanded wild holds its place during the respin, which reels the wild can appear on, or whether one respin can lead to another. Those points matter when you weigh what a single wild is worth, so open the in-game paytable before drawing conclusions. A short spell on virtual coins will show the respin more clearly than a written summary can.

Ordinary spins on ten lines

Without a wild on the reels, Starburst is a straightforward line slot. Matching symbols along any of the 10 paylines pay according to the paytable, and nothing else is happening in the background.

The 23% hit frequency is the figure most worth understanding here. Over a very large number of spins, about 23 in every 100 return something. It tells you nothing about the size of those returns, and it does not mean wins are spaced evenly. Long losing stretches and tight clusters of wins are both perfectly normal under that figure, and earlier spins have no influence on later ones.

The 96.08% RTP is also a long-run calculation, worked out across an enormous sample of spins. Over one sitting, results can sit well above or well below it. On a free-play demo its main use is as a point of comparison with other slots.

NetEnt’s page does not state whether lines pay left to right only or in both directions, so the paytable is the place to confirm that. The 800x maximum is a multiple of whatever stake is set, which is why the studio expresses it as a multiple rather than a fixed amount.

Theme and presentation

Starburst dates from January 2012, which makes it one of the older titles in NetEnt’s range. Its page now sits on netent.com, which belongs to Evolution.

The game is named after its wild, and that wild is the only special symbol in NetEnt’s description. The studio says far more about mechanics than about artwork or sound, so the demo is the best way to judge whether the look appeals. The plain 5×3 layout keeps the screen uncluttered, and with a single special symbol, a triggered feature is impossible to miss.

What it does not do

• No second feature. The expanding wild and its respin are the full list. Over a long session the lack of a free spins round or any other variation becomes noticeable.
• A low top end. NetEnt caps a spin at 800x. Players who look for very large multipliers will find that limiting.
• No published risk rating. With the volatility field empty, you have to infer the game’s character from the hit frequency and the ceiling.
• Mismatched third-party figures. Racing Post lists 96.1% RTP with a 250x maximum, and OLBG quotes up to 96.09% and refers to five other RTP settings. NetEnt itself lists only 96.08% and 800x, which are the figures used throughout this review.
• Unstated detail. Respin behaviour and payline direction are not covered in the studio summary, so the paytable has to fill those gaps.

Our verdict on Starburst

Starburst’s design and its published figures point the same way. A single expanding wild, a respin, ten lines, a 23% hit frequency and an 800x ceiling describe a slot built for frequent small events rather than one standout outcome. The 96.08% RTP from NetEnt is unremarkable, and the absent volatility rating is the biggest hole in the studio’s own information.

As a demo, it is one of the clearest ways to see how an expanding wild interacts with paylines, and it takes only a few minutes on virtual coins to understand. Anyone who prefers multi-stage bonus rounds, free spins or a high maximum payout will see from the numbers alone that Starburst was built with other priorities.
