Calcudoku: 121 Advanced Puzzles (Advanced Calcudoku Puzzles)

If you're looking for really challenging Calcudoku (also known as Kenken, Mathdoku, Kendoku, Hitoshii, and by many other names) puzzles, then look no further. Volume II has 121 new puzzles and many new puzzle variations: many different sizes, puzzles with exponentiation, without operators, extra large puzzles, and more. It also features extended explanations of the variations on the standard puzzle, as well as step-by-step solving guides for two tricky example puzzles. This new 2nd edition has a new cover design, and includes solutions to all the puzzles . The five largest puzzles are printed twice: once on a single page, and once on four separate pages so you can cut & glue to create a larger version. You can submit puzzle solutions online at www.calcudoku.org and score points for each correct solution.
