Book excerpt: Sudoku, the irresistible new pastime that works like a crossword puzzle, but with numbers instead of letters, takes a giant leap forward. "Magnetic Sudoku" offers 200 original puzzles, both the regular 9 x 9 type and easier 6 x 6 "warm-ups," all of which can be solved without a pencil (or an eraser) and played over and over again, thanks to the magnetic tiles included with the book. The puzzles are graded in four levels from Easy to Expert, and complete answers are provided. There are extra tiles and blank tiles, in case any get lost. And best of all, there are special placeholders that can be used to mark alternative possibilities until the definitive answer has been found.
