A wild landing on reel two, three or four rises to cover all three rows of that reel before any line is read. The rule works in free spins too.
Wilds that flood a whole reel
Floodwater landings change the reels before anything is paid. A wild on any of the three middle reels fills its whole column, so every line passing through that reel finds a wild there.
When two or three middle reels flood at once, many lines can connect in the same spin, which is where these landings find their larger awards. Wilds still never stand in for the scatter.
A worked example. A wild stops on the bottom row of reel four. It floods upward to fill the reel, and any line that already matches on reels one to three now carries on to four.
