With a long list of clues it is more difficult. However, not using a grid does give a puzzle more challenge, and to this end one flavour of logic problem caters for people with these tastes. I should point out straight away that these puzzles are usually less complex than puzzles that use a grid. They usually use fewer variables for example, instead of matching five men and five women with five times and five locations, you might just have to place ten schoolchildren in ten seats. The letter in the fifth position is a vowel.
L is somewhere between O and E, in that order.
D is the last letter. We'll go through the answer and do a more complex example next week. In the meantime, if you have any requests for anything you'd like to see covered in a future column, or you have comments about Puzzle Pieces, feel free to e-mail me at the address below.
