Your character as revealed by how you complete a puzzle
Pen: You prefer deductive reasoning. You expect ambiguity to resolve itself and to remain resolved. You know that each entry in the grid is waiting for one and only one word, and you withhold judgment until you are sure which one word that is. Then you can look at the crossing answers safe in the knowledge that the letters entered are correct. For you, the basic unit of information in a puzzle is The Clue. You may come unstuck, however, when The Clue equally suggests two answers and only the crossing letters reveal which is The Entry.
Pencil: You are one for inductive reasoning. You accept that even when something appears to be the case, you may have overlooked some key piece of information. You build your interpretation of the world and of a grid tentatively. You demand as much information as possible before you commit. For you, the most important unit of information in a puzzle is The Grid, and each answer depends on more than its clue. You may come unstuck when the space for a tricky clue is filled with lightly scrawled letters, some correct and some incorrect.
Wax crayon: You are desperate to solve, traveling with no writing implements other than something of your child’s (now fourteen) that you have inexplicably found in a pocket. You will come unstuck when the crayon becomes so blunt that each letter fills four squares at once.
