If a spin pays nothing yet shows one or more wilds, those wilds stay exactly where they landed and every other position spins once more.
Wilds tied up for a second spin
Moored-wild landings give an empty spin a second chance. The server notes each cell where a wild came to rest, keeps those cells as they are and spins all the others a single time.
Scatters that turn up on that extra spin still count towards free spins. A spin that already paid something does not get the extra turn, and the extra turn never repeats itself.
A worked example. A wild lands on the middle of reel two but nothing pays. It stays tied up while the other fourteen positions spin again, and a pair of matching symbols beside it can now complete a line.
