Dear All,

Is there are book of general logic definitions that uses a specific sudoku puzzle to explain each logic definitions? This beautiful langage of logic, is there such a thing as a sudoku-logic-dictionary?

We are new to this sudoku world and yesterday locked horns with a very difficult puzzle. It would be helpful (understatement) to be able to get hold of a key to moving to the solutions of these difficult puzzles.

At this point, we're stuck with dozens of clusters of tiny numbers in the box-tops and have no idea how to advance toward the solution.

3 cheers.
