Top Secret Sudoku System
What if you could solve any Sudoku puzzle with a bare minimum of penciling in and erasing (usually one or two penciled in numbers per cell, and never more than three), no educated guesses, and do it in less than half the time it takes you to solve a puzzle now? Well, we have developed an incredibly simple yet amazingly powerful system which limits the confusion of having four, five or more contingincies penciled in for each cell and can solve almost any Sudoku puzzle. This is not to say that we have taken the logic or the challenge out of solving Sudoku puzzles, we have not! You must still be thoughtful, thorough and sometimes imaginative, but you will have much MORE FUN solving them, with much less tedium and frustration.
