This survey is about Word Search puzzles, also known as word seek, word find, wonderword, etc.
Word search puzzles consist of a grid of letters in which a set of words have been hidden (horizontally, vertically, or diagonally) and your aim as a puzzle user is to find all the words. Some versions also make use of the unused letters to reveal a hidden message.
In this survey, we'd like to understand how we can improve the process of making word search puzzles.
