Play Starburst Slot Game

Starburst is widely considered the most iconic online slot ever made. Developed by NetEnt and released in June 2012, the Starburst slot has introduced more players to online gaming than any other title in history and remains one of the most-played slots in the UK regulated market more than 14 years after its release.

The Starburst slot is a fast-paced 5-reel video slot with a cosmic theme that blends arcade visuals with sharp, geometric gem symbols. The backdrop is a quiet galaxy scene, and the standout visual element is the multicoloured Starburst Wild that expands across reels 2, 3 and 4 to trigger re-spins. Unlike many modern slots, Starburst focuses on clarity and consistency, offering 10 paylines that Win Both Ways (paying from left to right AND right to left) for double the winning combinations on every spin.

The Starburst slot is rated low volatility with a 22.7% hit frequency, meaning a winning combination lands roughly once every 4.42 spins on average. The maximum win is 500x stake, achieved through filling the reels with the highest-value BAR symbols backed by expanding Starburst Wilds. It is a compact format built for smooth and direct play sessions and the slot most commonly featured in UK casino welcome offer free spins for over a decade.

Before launching Starburst, new users will need to register with Smooth Spins by providing a few basic details. After signing up, deposit funds securely using one of the supported payment methods listed in your profile. With your account active, type Starburst into the search bar and open the game from the slots games section. From there, you can set your preferred stake using the coin and level selectors on the game screen, then press spin to begin.

Steps to Play the Main Base Game

Starburst's layout is minimal but responsive, making it easy to get into the rhythm of spinning.

1. Choose your coin value and bet level from the bottom panel to define your total stake.
2. Click the central spin button to start the round across 5 reels and 3 rows.
3. Use the info button to access the paytable and understand how expanding Wilds behave when they appear.

The Starburst slot uses a tiered symbol structure with classic arcade icons at the top, gem symbols in the lower tier, and the iconic Starburst Wild as the only special symbol on the reels. There is no scatter symbol on Starburst.

Premium Symbols

The top-paying symbols on the Starburst slot are the classic arcade icons:

• BAR (highest-paying premium symbol)
• Lucky 7

Filling all 5 reels with BAR symbols delivers the maximum 500x stake payout when paired with the Win Both Ways mechanic.

Gem Symbols

The gem symbols form the lower-paying tier on the Starburst slot, each rendered as a brightly coloured 3D jewel:

• Yellow Gem
• Green Gem
• Orange Gem
• Blue Gem
• Purple Gem

The gems appear more frequently than the arcade premium symbols and form the base of the regular winning combinations during most spins.

The Starburst Wild Symbol

The Starburst Wild is the only special symbol on the reels and the defining mechanic of the entire game. The multicoloured Starburst Wild appears only on reels 2, 3 and 4 (never on reels 1 or 5). When it lands, it expands to fill the entire reel and triggers a re-spin with that reel locked in place.

Starburst Symbol Paytable

Payouts are calculated per active payline. Starburst uses Win Both Ways, so each combination effectively counts in both directions.

The Starburst slot does not rely on layered mini-games or traditional Free Spins rounds. Instead, the game focuses its energy on three core mechanics that all run continuously during base gameplay: the Starburst Wild with Re-Spins, the Win Both Ways payout system, and the absence of any scatter or bonus trigger that interrupts the natural spin flow.

Starburst Wilds with Re-Spins

The core bonus mechanic on the Starburst slot is the expanding Starburst Wild with re-spins. The Wild only appears on reels 2, 3 or 4 (never on reels 1 or 5). When a Starburst Wild lands:

1. The Wild expands to fill the entire reel from top to bottom.
2. That reel locks in place for the next re-spin.
3. A free re-spin is awarded with the locked Wild reel still active.
4. If another Wild lands on one of the other two middle reels during the re-spin, it also expands and triggers another re-spin.
5. The feature can repeat up to three times with all three middle reels (2, 3 and 4) locked as expanded Wilds.

Hitting three stacked Starburst Wilds across the middle reels is the dream sequence on the Starburst slot. With all three middle reels locked as expanded Wilds and the Win Both Ways system active, this combination can deliver the maximum 500x stake payout on a single re-spin sequence.

Win Both Ways Payout System

Unlike traditional slots that only pay from left to right, the Starburst slot pays from both directions: left to right AND right to left. This mechanic is always active on every spin and re-spin, and it effectively doubles the number of winning combinations that can form on each spin.

The Win Both Ways system is part of why Starburst has such a high hit frequency for a slot with only 10 paylines. The system was a genuine innovation when NetEnt released Starburst in June 2012 and has since been adopted by other slot studios across the industry.

No Free Spins or Scatter Symbols

The Starburst slot has no traditional Free Spins round and no scatter symbol that triggers a separate bonus mode. The expanding Wild Re-Spins act as the equivalent of a free spin mechanic, since every triggered re-spin is a free additional spin awarded on top of the original paid spin.

This minimal feature set is part of what defines the Starburst experience. Players who prefer multi-stage bonus rounds with multipliers and free spin counters will find Starburst lighter than modern releases. Players who prefer fast, clean gameplay with frequent re-spin triggers will find Starburst delivers exactly what they want.

Starburst’s clean layout and focused gameplay make it easy to compare with other well-known slots that prioritize pace and accessibility. Book of Dead remains a go-to for players looking for expanding symbol bonuses and straightforward mechanics. Gonzo’s Quest features cascading reels and a multiplier trail that builds tension as matches form. The Mega Moolah Goddess, while slightly more complex, is widely available and known for its simple base game paired with progressive jackpot potential. These titles consistently appear in casino libraries due to their lasting popularity and streamlined design.

The Starburst slot has earned its status as the most iconic online slot ever released over more than 14 years of continuous popularity. NetEnt built the game around three simple ideas (expanding Wilds, Win Both Ways paylines, and a clean cosmic aesthetic) and the combination has aged remarkably well in a market that constantly chases new mechanics and bigger maximum wins.

The low volatility rating is what makes Starburst so widely loved. Players get a winning combination roughly once every 4.42 spins, with the expanding Starburst Wild triggering re-spins frequently enough to keep sessions engaging without the long dry spells that high-volatility slots demand. The 500x stake maximum win is modest by 2026 standards (modern Megaways slots routinely advertise 10,000x or higher), but Starburst was never designed to be a big-game-hunting slot. It is designed for steady, frequent wins that stretch a bankroll across longer sessions.

For UK players, Starburst is also the slot most likely to be featured in welcome offer free spins. If you have ever opened a UK casino account, there is a strong chance the first slot you spun was Starburst. The Starburst slot is one of the strongest entry-level offerings in the Smooth Spins slot lobby and a must-try for any player new to online slots or returning to NetEnt's catalogue.
