Base Game & Features
Game Layout & Specifications
Butterfly Staxx presents a well-balanced five-reel, four-row grid with 40 fixed paylines, meaning every spin engages the full board without the need for payline adjustments. The five-reel configuration combined with four rows creates 20 symbol positions, providing ample opportunity for connecting winning combinations. The fixed paylines ensure consistent betting mechanics across all spins—you’re always playing with maximum payline coverage. Betting ranges from 0.20 credits minimum to 400 credits maximum, accommodating both penny slot enthusiasts and players with larger bankrolls. This broad betting range makes Butterfly Staxx accessible to players with varying budgets.

The Butterfly Re-Spin Feature
The core mechanic that defines Butterfly Staxx is its innovative Butterfly Re-Spin feature. When stacked butterfly symbols land on the reels, they flutter gracefully to the leftmost available position on their respective rows and lock in place. This lock-in triggers an automatic re-spin, and if new butterflies appear during that re-spin, the process repeats until no additional butterflies land. This cascading effect creates dynamic, engaging gameplay where a single spin can trigger multiple re-spins, building excitement and win potential with each animation.
The butterfly symbol itself pays impressively in base game combinations, delivering 60x your stake for five-of-a-kind wins. However, the real magic emerges when multiple butterflies stack and trigger the re-spin cascade. These re-spins can compound wins, contributing significantly to the game’s 640x maximum win potential. The visual execution is remarkable—butterflies genuinely appear to light up and dance across the reels, creating what players consistently describe as a “dream-like” gaming experience.
Visual Design & Theme
NetEnt has crafted a visually distinctive slot with a nature-inspired theme centred on butterflies and delicate flowers. The game employs a low-poly visual style that, combined with calming nature sounds and an immersive melody, establishes what many players describe as an enchanting, almost magical atmosphere. The colour palette features soft, natural tones—purples, greens, and pastels—that evoke a garden setting. Every animation, from the butterfly flutter to the cocoon glow, contributes to an immersive aesthetic rarely seen in standard video slots. This attention to presentation has made Butterfly Staxx a standout favourite among players seeking more than just mechanical spinning reels.
Bonus Features
Free Spins Bonus Round
Free spins are triggered by landing three or more scatter symbols (depicted as purple flower scatters) anywhere on the reels. The number of free spins awarded scales with scatter count: three scatters award 5 spins, four scatters grant 6 spins, and five scatters deliver the maximum of 7 free spins. This straightforward trigger mechanism provides clear gameplay expectations—players know exactly what’s required to unlock the bonus round.

Cocoon Transformation Feature
During the free spins round, the game introduces a unique twist: cocoon symbols appear on the reels. These dormant cocoons represent untapped potential—when triggered, they transform into butterfly symbols that immediately flutter to the leftmost available position on their row and lock in place, triggering automatic re-spins. This transformation mechanism means free spins feature enhanced win potential compared to the base game, as cocoons create additional opportunities for butterfly re-spins to compound. The visual execution—cocoons glowing before transforming into glittering butterflies—reinforces the magical theme throughout the bonus round.
Game Mathematics & Performance
Butterfly Staxx boasts a 96.8% RTP, a figure that consistently outperforms the industry average of 93–96%. This above-average payout percentage translates directly to better player returns over extended play sessions. Combined with the slot’s low volatility classification, players can expect frequent payouts—approximately one winning spin every four attempts, based on the game’s 24.9% hit frequency.
The maximum win of 640x your stake is achieved through a combination of high-paying butterfly symbols and the re-spin multiplier effect. While this ceiling is considerably modest compared to modern progressive jackpots and high-volatility slots featuring 5000x+ potential, it aligns perfectly with Butterfly Staxx’s low-volatility positioning. The game prioritises frequent, consistent payouts over headline-grabbing mega wins—a design philosophy that resonates strongly with casual players and budget-conscious gamblers.
Butterfly Staxx was developed using HTML5 technology, ensuring seamless playability across all devices—desktop computers, tablets, smartphones (both iPhone and Android), and modern smart TVs. The responsive design automatically adjusts the interface and gameplay to suit your device’s screen size without sacrificing visual quality or animation smoothness.
