Dudley’s Silhouettes

1. If the box is shaded, it indicates the silhouette designated DOES go in that spot.    

2. If the designated silhouette has a line through it, similar to the “no” symbol then that silhouette does NOT go in the shaded space.  

3. If only a shape is shown, then one of the silhouettes of that shape goes in the shaded square, but you may have to wait to determine which one.    

4. If more than one square is shaded for a particular clue, then you have to choose (by using some of the other clues) which shaded square is the correct spot for the silhouette in question.    

5. If there is a selection of boxes and the designated silhouette has a line through it, then that silhouette will not go in ANY of the shaded squares.    

6. If there is already a silhouette shown in place on one of the clues, that silhouette’s location must be determined before the designated silhouette can be established. Knowing the placement of the first silhouette is part of the clue to where the other silhouettes will go. This rule applies to puzzles 4, 5, and 6.
