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.
As you already know, some of these choices are simply a way to "kill some time". But some other fun hobby ideas will actually relax your mind and body, and help you grow your skills in the process.
