Type of play
- Must-hit/positive-state play based on persistent wild reels already “banked” on the machine.
How the advantage works
- When a full-reel wild appears, it becomes a persistent wild reel.
- That wild reel shifts one reel to the left each spin until it reaches reel 1, then it moves off the screen on the next spin.
- Your edge comes from playing only while those persistent wild reels are active (extra wild coverage for a few spins).
