This is a second book in the Double Samurai Sudoku HARAKIRI series of books! It is full of overlapping 8-grid Sudoku puzzles (Gattai-8) laid out in a double Samurai Sudoku format known as SUDOKU HARAKIRI. Essentially, there are 8 sudoku sub-puzzles which overlap the same way as in Samurai Sudoku. Therefore, each puzzles provides twice the challenge of an ordinary Samurai Sudoku! But wait! In this volume, things get even more complicated. In addition to normal (aka “vanillaâ€) Harakiri puzzles, there are variants of the following types: Jigsaw Harakiri, Consecutive Harakiri, Diagonal Harakiri, Hyper Harakiri and Non-Consecutive Harakiri! Are you up for this challenge?
