Scatters

Bonus Features and Free Spuns

"Puffer Stacks" has a unique feature known as "Stacked Wilds", where multiple Puffers appear on adjacent reels, increasing winning potential. The feature is triggered randomly during gameplay and remains active for 3-5 consecutive spins.

  1. Level 2 : The reel with a Puffer stacks 4 Wilds.
  2. Level 3 : One of each row (top to bottom) fills up with one symbol from the selected reels’ top row.
