The game box contains 4 identical 20 piece jigsaw puzzles, and two special "bat" pieces which do not go into the puzzle. Players start with 5 random pieces, and take turns drawing one piece out of the box. All pieces except the "bat" pieces have text written on the back, which is one of: "Holy jigsaw, use this piece", "Zowie! pick 2 more pieces", "holy Batmobile, pick 1 more piece", "Zap! Lose one piece", or "Riddler strikes lose 2 pieces." If a player draws one of the "bat" pieces he returns it to the box and takes a piece from any other player. Players may keep duplicate pieces which are useful when directed to lose one or two pieces. When drawing as directed by the text on the back of a piece, text is not read or followed on the pieces drawn, and if a "bat" piece is drawn this way it is returned until a non-bat piece is drawn. The game is won when a player completes his 20 piece puzzle.
