Slot Summary

For a Low volatility slot that needs more than standard line wins to hold attention, Butterfly Staxx uses migrating butterflies as the event between paid spins. NetEnt's 2017 release turns a full reel of butterfly symbols into Respins, moving them left while the remaining symbols spin again. Butterfly Spins then shift the same Nature theme into a cocoon transformation feature, giving the 40-line game a second mechanical identity.

How It Plays

Base play evaluates combinations across 40 fixed paylines. A complete stack of butterflies interrupts that line cycle and starts a no-cost Respin sequence.

During Respins, butterfly symbols move toward the leftmost available position in their rows while other positions spin again, potentially adding further butterflies to the sequence.

Theme & Atmosphere

Butterfly, Flowers, and Nature imagery give the game a calm garden subject, with the insect movement carrying equal importance as both animation and mechanic.

NetEnt used a low-poly visual treatment for the Fantasy setting, turning tropical flora and fluttering butterflies into clean geometric forms rather than realistic illustration.

Features & Win Potential

Respins begin from a complete butterfly reel and continue while further qualifying butterflies appear, giving the feature a visible direction of travel across the grid.

Wild and Scatter symbols retain conventional roles, but Free Spins replace ordinary symbols with cocoons and make transformation the central event of the round.

Bonus & Free Spins

Three or more Scatters award Butterfly Spins. The number of awarded spins varies with the triggering Scatter count, and the feature cannot retrigger itself.

During Butterfly Spins, active cocoons transform into butterfly symbols while sleeping cocoons remain unchanged, making each revealed cocoon relevant to the final result.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (Low). The model is calibrated so the average return equals this slot's published RTP (94.05%), with wins capped at its top multiplier (1,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
