This is a Wednesday Corral puzzle, with a twist. The solution is composed of two loops, one contained completely inside the other. The loops do not intersect, even at a point. A number contained in both loops tells how many squares it can see inside the inner loop. A number contained in only the outer loop tells how many squares it can see inside the outer loop, ignoring the inner loop entirely.
(Think of the loops as cliffs and the clues as people. People inside both loops are at the lowest elevation and can only see what’s down there. People inside one loop are at the middle elevation and can see anything except for what’s at the highest elevation, namely the squares outside both loops.)
All of the types and variations I’ve posted have either been developed by nikoli or myself until now. The idea for this variation was actually given to me awhile ago by reader Alan Curry, and I thought it was definitely worth trying. Probably mostly due to size, this one is solved in a rather peculiar fashion. When I post another of these it will probably be bigger.
This is a Friday Corral puzzle, with a twist. The edges of the grid wrap around to each other. The solution is a single connected loop that may cross over the edges and that partitions the grid into “walls” and “empty spaces” (I would not say inside and outside). Note that all clues in this puzzle are finite, so there is no clue that can see a whole row or column (and thus see infinitely far).
