What are diagrams and how are they solved?

Word searches are puzzles that do not require a special level of knowledge. The goal is for the solver to find the words hidden in the grid with the random letters listed and to delete them all one by one. There are four- and eight-way diagrams. Those of the four directions have words horizontally, vertically and vice versa in these two directions. Eight-way diagrams have words arranged in all directions, ie horizontally, vertically, diagonally (from top left to bottom right and from top right to bottom left) as well as vice versa in all these directions. When a diagram does not state somewhere the directions in which the words develop, then the diagram is four-way.
