Beginner’s Guide to Starburst and Starburst XXXtreme Online Slot
If you asked UK slot players to name the most recognisable online slot ever made, Starburst would almost always be mentioned.
Since launching in 2012, it has been played billions of times. It became the first slot many UK beginners tried, mainly because it was heavily featured in free spin promotions, but also because it was simple, fast, colourful, and easy to understand. Nearly a decade later, NetEnt released Starburst XXXtreme, an explosive, high-volatility evolution of the classic game designed for players who wanted something more intense. It kept the iconic look and feel of the original, but raised the stakes with bigger wild multipliers, a far more volatile maths model and the optional XXXtreme spin-buy feature.
This guide walks through both versions of the game, comparing how they work, their RTP, volatility, features, max win potential and mobile experience. It’s written for beginners and designed to help you understand which game better suits your style.
Game Overview: Original Starburst, Studio Background, Theme, Symbols and Visual Style, Core Mechanics, The Starburst Wild Feature and RTP and Volatility
Game Overview: Original Starburst
Starburst is a 5-reel, 3-row slot with 10 paylines, but it stands out because wins can form both ways, from left to right and from right to left. This makes it easier for beginners to follow and provides more frequent small wins.
The game uses bright gem symbols and a cosmic-style background. There are no complicated bonus rounds. No free spins. No multi-stage mechanics. Everything centres around the Starburst Wild.
Core details (Original Starburst):
· Reels: 5
· Rows: 3
· Paylines: 10 (pays both ways)
· RTP: 96.09%
· Volatility: Very low
· Theme: Cosmic / gem arcade
· Developer: NetEnt
· Launched: 2012
Studio Background: NetEnt
NetEnt is one of the leading developers in the online casino world, known for smooth mechanics, excellent sound design and polished visuals. Starburst became their breakthrough global hit. It appeared in more welcome bonuses than any other slot and quickly became a “gateway” game for new players in the UK.
Theme, Symbols and Visual Style
Starburst keeps things simple. Bright gems fill the reels, accompanied by BAR symbols and sevens for higher-value wins. The background pulses with neon energy, and the sound effects are clean and futuristic, inspired by old-school arcade games.
Symbols:
· Purple gem
· Blue gem
· Green gem
· Yellow gem
· Orange gem
· Red gem
· BAR symbol
· Lucky 7 symbol
The sound design uses soft pulses, rising tones and satisfying clicks that make every spin feel active.
Core Mechanics: How the Original Starburst Works
Starburst is clear and accessible:
· Choose your stake.
· Spin.
· Match symbols from left to right or right to left.
· Hope for expanding wilds.
The Starburst Wild Feature:
· Wilds land on reels 2, 3 or 4.
· They expand to fill the entire reel.
· They trigger a re-spin.
· If more wilds land during the re-spin, you get another re-spin.
· Up to three re-spins can chain together.
Starburst built its global reputation on this one feature. It’s simple, satisfying and ideally suited to new players.
RTP and Volatility (Original Starburst)
· RTP: Usually 96.09%.
· Volatility: Very low.
This combination makes the game feel smooth and predictable. Wins appear frequently, but they’re usually small. Dry spells are rare, and the expanding wilds help maintain excitement.
