Sherlock is a game of deduction.  It is your task, based upon the information available in provided clues, to determine the locations of 36 blocks.  Every puzzle can be solved by using the clues to eliminate possibilities until the location of a specific block can be determined.
Sherlock may be played by a SINGLE person, or a TOURNAMENT may be set up, with each person in the TOURNAMENT attempting to solve the same puzzle as quickly as possible.  A TIME LIMIT may be set if desired.
