Ultra Stack Feature Butterfly Slot Video - LIVE PLAY BONUS!
The Ultra Stack Feature Butterfly slot machine by Aruze is very similar to Ultra Stack Feature Panda!
Although it has a slight twist: you actually choose how many extra top symbols are added into your bonus! Other than that, it plays the same: First, to trigger the bonus you need at least one bonus symbol in columns 1, 2, and 3. Like all other symbols in the game, bonus symbols are also "Super Stacked" and you have the chance to fill the entire screen with bonus symbols.
Once triggered, each bonus symbol is then replaced by a number of free spins, which are totaled giving you your final tally of free games. You then choose a flower to determine the number of top symbols from top 25 to 200, although I'm not sure how large the reels are, so it may not have that much of an effect. Retriggers are possible, although like Panda, a lot of dead spins with this one, but Enjoy!
