Another complicating factor is whether you download the file or a page, print a page, or sign up for an emailed download. All three work, but some form of file will be most flexible. Usually you have to pay for that.
Word search puzzles are grids of letters arranged in rows and columns. At first glance they appear to be a completely random mishmash of letters, but if you look closely you can see within the grid that there are hidden words. The words may be placed horizontally (either left to right or right to left), vertically (upwards or downwards) or diagonally. The goal of the puzzle is to find the words hidden within the grid. Many people find these puzzles to be an interesting diversion, and you will often see this type of puzzle printed in magazines or newspapers. But it's not only adults who may enjoy these puzzles _ many children like solving them too.
