Visual Theme & Mobile Compatibility

Every symbol is detailed and animated with personality.

Key Features & Bonus Mechanics

Wild Symbols
Wilds in Thunder Birds function as standard substitutes for base symbols. However, they are far from ordinary. Certain wilds expand vertically or horizontally and may carry win multipliers. These wild-enhancing effects primarily occur during bonus features and can dramatically elevate your payout potential when aligned with premium symbols.

Mystery Symbols
The game includes a mystery symbol mechanic that adds unpredictability and surprise to each session. These symbols appear at random and, once the reels stop spinning, they simultaneously transform into the same random symbol. This can lead to large cluster wins or set the stage for feature triggers.

Free Spins Feature
Thunder Birds truly comes alive in its free spins mode, activated by landing three or more scatter symbols. Depending on how many you hit, you can earn:

• 3 scatter symbols – 10 free spins
  
• 4 scatter symbols – 20 free spins
  
• 5 scatter symbols – 50 free spins
  

During free spins, special enhancements come into play. Wilds often become sticky, remaining in place for the duration of the bonus round. A golden totem symbol can land on the third reel and trigger multipliers up to 5x, applied to any winning combination on that spin.

Free spins are retriggerable. Landing additional scatter symbols during the feature adds more spins, extending the session and increasing your chance to hit big.

Bonus Surprises from Mystery Symbols
Beyond standard transformations, mystery symbols have a chance to reveal instant coin prizes or hidden mini-game elements, though these mechanics are subtle and vary per session. They keep gameplay dynamic without breaking immersion.
