Where to play for real
Wild Eyeballs and Energy Fields
- An Eyeball symbol shoots in one of three directions – straight up, diagonally left or diagonally right – and turns paying symbols in its path into wilds.
- If it hits an Energy Field, it bounces off in another direction and keeps transforming symbols.
- If it hits an existing wild or Eyeball, that wild receives a multiplier.
Bonus games
- Eyeconic (3 FS): 10 free spins with a higher chance of Eyeballs.
- No-Brainer (4 FS): 10 free spins in which Eyeballs shoot in two directions.
- It’s Electrifying (5 FS, hidden): 10 free spins with at least one Eyeball on every spin.
Bets range from 0.10 to 100, and a feature buy is available. Watch the eyeballs bounce in the free demo.
