It is based on the Looney Tunes cartoons with some of the all time favorite characters like Bugs Bunny, Daffy Duck, Tweety & Sylvester, Pepé Le Pew, The Tazmanian Devil, and others. Any of these puzzles can be scaled up and down the difficulty scale, from level one (five pieces, mildly challenging) to level five (hundreds of pieces). The program even has two interfaces, one with pull-down menus, presumably for adults, and the other with large cartoon icons, for kids.
