Puzzle[Puzzle?:jigsaw puzzle] design varies depending on the type of artwork and the style of puzzle desired. The design of the cuts is hand drawn by artists and, consequently, no two puzzles are alike. Quality puzzles are designed to artfully combine the picture with the design of the cut pieces to enhance the enjoyment of the user. Puzzle artists are cautious in their design not to cut through major features of the artwork such as a person's face. The artists control the puzzle's skill level by varying the number of pieces and the complexity of the cuts. Typically, the more pieces the puzzle is cut into, the more difficult it is to assemble. Some puzzle makers make their puzzles even harder to assemble by avoiding straight-edged border pieces. The lack of a straight border makes the edge pieces harder to locate.
