The benefit of making your own puzzles is that you get to choose the topic. Are you obsessed with Star Trek? Then make your own word search full of your favorite Star Trek words and hunt them all down! Is your partner a geologist? Why not make him a puzzle full of geological words as a random present? It's sure to make them smile! Or perhaps your child has recently become obsessed with dinosaurs? You could create a puzzle specially for them filled with words they will recognize, and add in a few they don't yet know to help encourage them to learn more!
At some point in their lives, the majority of people have probably come across word search puzzles. Basically these puzzles are a grid of letters containing various words placed in all types of directions (from left to right, from right to left, up and down the page, and in each of the various diagonal directions). Additionally, the words can overlap too, and any unused squares in the grid are filled with a randomly chosen letter.
