I came across a new kind of puzzle called shinro that can be found in Southwest Airline magazines. According to the magazine, shinro is Japanese for “compass bearing.” The puzzle involves finding holes in a square grid. Like battleship puzzles, the number of holes in each row and column are indicated. In addition, there are a number of arrows in the grid that point to at least one hole.
I can’t find any other examples of this specific kind of puzzle on the web. So, I’m interested to hear if anyone else has found some. I’m also interested in trying to make some of my own shinro or shinro-like puzzles. So keep an eye out for that.
