The basic rule is that each number represents a set of blocks in that row or column that will be filled in a row, followed by one or more blocks not filled in (Unless they touch the puzzle's edge). I would recommend checking out an online source to learn how to play Picross. Try searching Youtube!
Cache is not at the posted coordinates, but is located within 3km
To find the coordinates for this cache, you must solve two Picross puzzles:
