Today's puzzle solving resource is a web script that helps you solve Logic Grid Puzzles, similar to this one:
You have to enter all of the information from the puzzle yourself, including associations given by the puzzle. The solver will then begin suggesting answers. It sometimes takes a little finesse, and adding some associations that aren't directly obvious from the clues (in other words ones that you have deduced for yourself) to give the system enough information to solve, but you eventually reach critical mass and the answers are revealed. It will also allow you to bookmark, save or send the puzzle including the information that you have input, to share the puzzles with others.
