Butterfly Staxx slot: features and gameplay
Butterfly Staxx is a video slot featuring symbols that can connect across the reels. This low-variance game invites players to collect butterfly symbols to trigger respins and pursue its best 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
The slot’s theme centres on butterflies in a peaceful natural setting. A scenic mountain lake at sunset sits behind the reels as the insects prepare to settle in for the night.
Graphics, sound and animation
Butterfly Staxx pairs vibrant symbols with a dark backdrop, and its transparent reels run smoothly on desktop and mobile. The setting brings the butterflies’ habitat to life with animated green fireflies, mountains, trees and a lake. NetEnt adds movement throughout: butterflies flutter across the reels, flowers bloom, and bright trails of stardust drift by. A soft, dreamy melody blends with birdsong and a range of magical sound effects.
Top Casinos for Butterfly Staxx:
How the gameplay works
The game has 5 reels and 4 symbol rows. Behind them, 40 fixed pay lines award winning combinations worth up to 60 coins per level. Choose from 1 to 10 levels; each level adds 20 coins to the reel wager.
When 5, 4, 3 or 2 yellow butterflies land on a pay line, they award 60, 30, 15 or 2 coins per level wagered. These payouts are equivalent to 3x, 1.5x, 0.75x and 0.1x the spin bet, respectively. For instance, at level 2 the spin wager is 20 x 2 = 40 coins, while 5 yellow butterflies pay 60 x 2 = 120 coins. The same calculation applies to other symbol combinations.
There are 3 flower colours. A line of matching flowers pays 40, 20 or 10 coins per level for 5, 4 or 3 symbols, equivalent to 2x, 1x or 0.5x the spin bet. A, K, Q and J symbols pay 1x, 0.5x or 0.25x the spin bet per level for 5, 4 or 3 matching symbols on a pay line.
Winning combinations must start on the specified reels: 1-2-3, 1-2-3-4 or 1-2-3-4-5. For the yellow flower, a 2-symbol combination must land on reels 1-2. The game also features a wild that substitutes 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 move to the next available reel on the left. Any single or stacked butterflies that land during re-spins trigger another re-spin and also travel left. Keeping butterflies on the reels throughout 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 a butterfly, where it remains for the rest of the free spins bonus game.
Bet sizes, RTP and variance
Each Butterfly Staxx spin has a fixed wager of 20 coins. The ‘Coin Value’ setting determines the cash value of each coin, from 0.01 to 2.00. At 20 coins valued at 0.01, the minimum stake is 0.20; setting 20 coins to 2.00 gives a maximum of 40.00 per spin. The game is described as low variance, with an RTP of 96.8%, about 0.8% above average. RTP is a theoretical long-term measure, not a guarantee for any session.
Conclusion
Evan Carrington’s review describes Butterfly Staxx as a polished online slot from NetEnt. Its symbol-combination payouts are modest beside those of other online slots. Many slot games pay 20x a bet or more for their top symbol; here, that symbol returns just 3x the spin bet. The review notes this may put some players off, while characterizing the game as low variance, with frequent smaller wins. More frequent payouts often go hand in hand with lower symbol multipliers, so the modest top-symbol return is consistent with that profile.
The review also points out that several Butterfly Staxx symbols have identical payout values. It suggests this narrows the range between outcomes and helps account for the game's relatively high RTP. RTP is a statistical long-run measure, not a promise of results for an individual player.
