Butterfly Staxx Slot: Features and Gameplay
Butterfly Staxx is a video slot built around symbols that can connect across the reels. In this low-variance game, collect butterfly symbols to trigger respins and pursue its top combinations. A separate free-spins round lets butterflies stay in place on the reels, potentially creating repeated symbol combinations across several paylines from a single spin.
Theme and story
This slot takes its theme from butterflies in a peaceful natural setting. Behind the reels is a scenic mountain lake at sunset, as the insects prepare to settle for the night.
Graphics, Sound, and Animation
Butterfly Staxx sets colorful symbols against a shadowy backdrop, with transparent reels that spin smoothly on phones, tablets and computers. Its animated setting features green fireflies, mountains, trees and a lake in the butterflies’ habitat. NetEnt brings the scene to life with butterflies fluttering across the reels, flowers blooming and sparkling stardust drifting past. A soft, dreamy melody blends with birdsong and magical sound effects.
Top Casinos to Play Butterfly Staxx:
How the gameplay works
The game has 5 reels and 4 symbol rows. Its 40 fixed pay lines award wins worth up to 60 coins per level. Choose between 1 and 10 levels; each level adds 20 coins to the reel wager.
A yellow butterfly pays 60, 30, 15 or 2 coins ‘per level’ wagered for 5, 4, 3 or 2 symbols on a pay line. These payouts correspond to 3x, 1.5x, 0.75x and 0.1x the spin bet. For example, at level 2, the spin wager is 20 x 2 = 40 coins, and 5 yellow butterflies pay 60 x 2 = 120 coins. The same calculation applies to other symbol combinations.
The game features 3 flower colours. Matching flowers pay 40, 20 or 10 coins per level for 5, 4 or 3 symbols on a pay line, equal to 2x, 1x and 0.5x the spin bet. A, K, Q and J symbols pay 1x, 0.5x and 0.25x the spin bet per level when 5, 4 or 3 appear on a pay line.
Wins count only when symbols start on the required reels: 1-2-3, 1-2-3-4 or 1-2-3-4-5. For the yellow flower, a 2-symbol win must land on reels 1-2. A wild symbol can substitute for any of the 8 regular symbols.
Bonus Features and Free Spins
Re-spins: The feature begins when a stack of glowing white butterflies fills all 4 positions on a reel. The butterflies shift to the next available reel on the left. Any individual or stacked butterflies landing during re-spins trigger another re-spin and move left as well. Keeping butterflies on the reels during the feature is designed to help form more winning combinations.
Butterfly Spins: Landing 3, 4 or 5 scatter symbols awards 5, 6 or 7 free spins, respectively. Cocoon symbols may appear during the round, some active and others dormant. Each active cocoon transforms into a white butterfly. Every activated butterfly moves to the leftmost reel not already occupied by one and remains there for the rest of the free spins bonus game.
Bet sizes, RTP and volatility
Each Butterfly Staxx spin has a fixed wager of 20 coins. The ‘Coin Value’ setting determines the cash value of each coin, ranging from 0.01 to 2.00. At 20 coins valued at 0.01, the minimum stake is 0.20; valuing 20 coins at 2.00 makes the maximum 40.00 per spin. The game is described as low variance, with 96.8% RTP, about 0.8% above average. RTP is a theoretical long-term measure, not a guarantee for any individual session.
Conclusion
Evan Carrington’s review, presented by Al Buraq Regina, describes Butterfly Staxx as a polished online slot from NetEnt. Its symbol-combination payouts are modest beside those of other online slots. Many slots award 20x a bet or more for their top-paying symbol, while Butterfly Staxx pays just 3x the spin bet for that symbol. The review suggests this could put some players off, but characterizes the game as low variance, with frequent smaller wins. Frequent payouts often accompany lower symbol-combination multipliers, so the modest top-symbol return is consistent with that profile.
The review also points out that several Butterfly Staxx symbols have the same payout values. It argues that this reduces the gap between outcomes and helps account for the game's relatively high RTP. RTP is a statistical long-run measure, not a guarantee for an individual player.
