Reels, Paylines, or Grid Mechanics

- Standard spin : Each player bet is divided by the fixed minimum payout for each winning combination.
- Winning streaks : Winning symbols create a cascading effect, with subsequent spins potentially generating further wins based on available spaces in the grid.
- Free Spins : Triggered by three or more Scatters, free spins offer players additional opportunities to win without using credits.

As mentioned earlier, Puffer Stacks includes Wilds (red/blue pufferfish) that can replace other symbols. These are scattered throughout the reels, providing a chance for bigger wins in various combinations:
- Multiple wild : When multiple Wild symbols appear on a single reel, they can combine to form more complex winning patterns.

- Free spin awards : 10-20 free spins awarded depending on scatter combinations.
- Standalone free spins round : No bonus features can be activated during this round.
