Crosswords are effective games of logic because they tap on your creativity and general knowledge for you to get the right answers. Note that the clues are sometimes too general so you will have to rely on trial and error to zero in on the perfect answers. When you’re doing crosswords, you are also improving the essential life skills of focus, self control and patience.
