Butterfly Staxx slot: features and gameplay
Butterfly Staxx is presented as a video slot built around symbols that can link across the reels. This low-variance game asks players to collect butterfly symbols to activate re-spins and pursue its strongest combinations. A separate free-spins round lets butterflies remain in place on the reels; this can support repeated symbol combinations across several pay lines from one spin.
Theme and story
This slot draws its theme from butterflies in a tranquil natural setting. Behind the reels sits a scenic mountain lake at sunset, as the insects prepare to settle for the night.
Graphics, sound and animation
Butterfly Staxx places vivid symbols against a dark backdrop, allowing its transparent reels to spin smoothly on mobile and desktop devices. The scenery includes animated green fireflies, mountains, trees and a lake representing the butterflies’ habitat. NetEnt adds movement throughout, with butterflies crossing the reels, flowers opening and bright stardust patterns drifting over them. The soundtrack combines a gentle, dreamy theme with background birdsong and a selection of magical sound effects.
Top Casinos to Play Butterfly Staxx:
How the gameplay works
Butterfly Staxx runs on 5 reels with 4 symbol rows. Behind them, 40 fixed pay lines collect winning combinations worth up to 60 coins per level. Players can choose from 1 to 10 levels, and every level adds 20 coins to the reel wager.
The yellow butterfly awards 60, 30, 15, or 2 coins ‘per level’ wagered when 5, 4, 3, or 2 appear on a pay line. These amounts equal 3x, 1.5x, 0.75x, and 0.1x the spin bet, respectively. For example, with 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 the other symbol combinations.
There are 3 flower colours. The same-colour flower payout is 40 coins, 20 coins, or 10 coins per level for 5, 4, or 3 on a pay line; these values equal 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 line up on a pay line.
Symbol combinations pay only when they begin on the required reels: 1-2-3, 1-2-3-4, or 1-2-3-4-5. For the yellow flower, the 2-symbol combination must appear on reels 1-2. Butterfly Staxx also includes a wildcard that can replace any of the 8 regular symbols.
Bonus features and free spins
Re-spins: The re-spin feature starts when a stack of glowing white butterflies fills all 4 positions on a reel. Those butterflies move to the next available reel on the left. Any individual or stacked butterflies that land during the re-spins start another re-spin and also travel left. Keeping butterflies on the reels throughout the re-spins is intended to help connect more winning combinations.
Butterfly Spins: Landing 3, 4, or 5 scatter symbols awards 5, 6, or 7 free spins respectively. During this round, cocoon symbols can appear; some are active and others dormant. Each active cocoon changes into a white butterfly. Every activated butterfly moves to the leftmost reel not already occupied by a butterfly and stays there for the rest of the free spins bonus game.
Bet sizes, RTP and variance
Each Butterfly Staxx spin uses a fixed 20 coins. The ‘Coin Value’ setting determines each coin’s cash value, with a min-max range of 0.01-2.00. At 20 coins worth 0.01, the minimum stake is 0.20; setting 20 coins to 2.00 produces a maximum of 40.00 per spin. The source describes the game as low variance and lists 96.8% RTP, about 0.8% above average. RTP is a long-run theoretical figure, not a promise for an individual session.
Conclusion
The review by Evan Carrington, as summarized by GCCans, presents Butterfly Staxx as a polished online slot from NetEnt. Its symbol-combination payouts are modest compared with other online slots. Whereas many slot games offer 20x a bet or more for the highest-paying symbol, Butterfly Staxx returns only 3x the spin bet for that symbol. The review suggests this may discourage some players, but describes the game as low variance, with frequent smaller wins. More frequent payouts commonly come with lower symbol-combination multipliers, so the modest top-symbol return fits that profile.
The review also notes that several Butterfly Staxx symbols share payout values. In its assessment, this narrows the spread between outcomes and helps explain the game's relatively high RTP; RTP remains a statistical long-run measure rather than a guarantee for an individual player.
