A wild that lands on any of the three middle reels unfurls like a sail to cover every cell of that reel, and only then are the lines counted. Wilds appear more rarely on these islands, since each carries far more weight.
Wilds that unfurl down a whole reel
Full Sail Wilds islands reshape the screen first and pay second. One wild on the second, third or fourth reel is enough to turn the whole of that reel wild.
With two or three reels unfurled, a great many lines can connect in the same spin, and that is where these islands produce their biggest awards. The rule holds in free spins exactly as it does in ordinary play.
Worked example. A wild lands at the top of reel two and fills the reel. Any line with matching symbols on reels one and three now pays, whichever row it crosses on reel two.
