Bonus functions and unique mechanics
The main feature of Butterfly Staxx — these are its proprietary bonus functions that work on the principle of respins:
- Butterfly Respins: this is the key mechanic of the game. When a stack (full column) of golden butterfly symbols appears on the reels, it becomes active. All other symbols disappear, and the butterflies shift left, filling the first columns. Then a series of free spins is triggered while butterflies remain on the screen. This can lead to significant wins.
- Butterfly Spins: this function is activated when three or more Scatter symbols (flower with the 'Bonus' label) drop on the second and fourth reels simultaneously. The player receives 7 free spins. During the free spins, any butterfly stacks that land on the reels remain in place until the end of the round, which significantly increases the chances of activating Butterfly Respins.
- Wild symbol: represented as the Butterfly Staxx logo. It substitutes for all regular symbols, helping to create winning combinations. However, it does not substitute for Scatter symbols.
- Scatter symbol: a flower with the 'Bonus' label. It does not bring direct payouts, but triggers the bonus game Butterfly Spins.
