Word Square Builder for Mac

From Scattersoft:

Word Square Builder is for building word search puzzles where interlocking words are hidden in a grid of letters. It allows the user to enter, save and reuse word lists, control the size and shape of the puzzle, flow the puzzle around irregularly shaped pictures, control the font and letter spacing, select the characters that may appear in the puzzle, select the directions in which words are permitted to run, print puzzles and puzzle solutions, and export puzzles as graphics files for use in DTP or on the web.

Special features of the program include: the Mask Editor which allows the user to draw shapes into which the puzzle will fit, and Auto Mask which helps create masks to flow the puzzle around the outside of pictures. The program also supports the export of puzzles (including embedded graphics) in many different formats suitable for the web or DTP.
