As described by Puzzle Baron's website: "A reverse word search puzzle is pretty much exactly what it sounds like - basically a regular word search puzzle, but solved in reverse! You're given a list of words and a mostly empty grid. A small number of letters are pre-placed on the grid to indicate the starting letter of each word in the list. Your task is to place each word into the grid (horizontally, vertically or diagonally in either direction) in such a way so that every word is placed once, every starting letter is used at least once, and every square on the grid is filled. Each puzzle has only one unique solution, and each solution can be reached using pure logic (guessing and trial and error are never required!)."
