More about the book
These 180 multihued puzzles come in a rainbow of glorious colours and patterns that enhance the fun. Although they begin with the standard 9x9 grid and follow the basic rules, each sudoku offers a fresh twist to tradition: perhaps every red square must contain a different number, or a puzzle may look like a jigsaw.
