发明名称 PUZZLE
摘要 <p>A number of square pieces having matching corner patterns and are arranged in sets so that each set may be assembled with the preceding sets to form a square in which the patterns on all mutually adjacent sides of the pieces match. SPECIFICATION The present invention relates in general to puzzle type amusement devices, and it relates in particular to a novel puzzle consisting of a plurality of sets of square pieces which may be arranged in a unique manner to form a square in which visible patterns on the four corner portions of the pieces match together to form a predetermined, recognizable design. BACKGROUND OF THE INVENTION Puzzles in which a plurality of pieces are interfitted or otherwise mutually arranged so that visible patterns on the pieces are matched to form an overall design or picture are well known. As the parts of such puzzles are put together the degree of skill required to add another piece diminishes until the placement of the last piece requires very little, if any, skill at all. Consequently, the most difficult steps in solving such puzzles occur near the beginning and yet there is little sense of accomplishment until much of the puzzle has been completed. It would be desirable, to provide a puzzle of this general type which becomes progressively more difficult as the parts</p>
