Sudoku Dojo

Puzzle sensei Frank Longo is ready to turn sudoku weaklings into bona fide samurai. Sudoku Dojo builds logical thinking and deductive reasoning as only high-level sudoku can, but the way of the warrior is a trying path. Starting with puzzles that can be solved with One Look and Scanning, and gradually working up to puzzles that require black-belt techniques like Squirmbag and Jellyfish, Longo's Sudoku Dojo will turn any humble beginner into the Bruce Lee of logic.
