Logic Puzzles

These are problems with clues like:

“Mr. Green lives between the model train enthusiast and the grocer, 2 doors from the blue house.”

From an assortment of such clues one must deduce such things as the color and order of the houses on the street, the owners’ names, their occupations, and their hobbies. The solver ordinarily uses charts to record and organize deductions as he proceeds to isolate the solution by logical elimination of possiblilties.

“When you have eliminated the impossible, whatever remains, however improbable, must be the truth.” —Sherlock Holmes in The Sign of the Four
