It is possible to buy books printed with word search puzzles, however a more flexible option is for a parent or teacher to create the puzzles themselves with the help a computer and word search puzzle maker software. Simply enter a list of words, and the computer can generate a puzzle in an instant! Doing it this way has the big advantage that you can tailor the puzzle, for example choosing words based on this week's spelling list or around class project, or perhaps turning off some of the more difficult directions when creating puzzles for younger kids.
For anyone not familiar with the concept, these puzzles presents you with a grid of letters, seemingly all jumbled up, and a list of words. Your challenge is to find all of the words hidden within this grid. These puzzles are often designed as word searches for kids with a short list of simple words, and with those words only appearing in the grid in natural directions (horizontally left to right, and vertically top to bottom). However, the searches can be aimed at any age group, using far more complex lists of words and with the words appearing in any of all 8 possible directions.
