Download or read book Kendoku written by David Levy and published by Seven Footer Press. This book was released on 2009-02 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: The puzzles, either 6 x 6 or 9 x 9, look like Killer Sudoku games, but in addition to numbers, players also contend with math operators (+ - × ÷) within "fences" on the puzzle. Players reach the total at the top left of the fenced area by using the operator on all the numbers within it. Although the solution is a valid Sudoku solution, Kendoku numbers are allowed to be repeated within a fenced area as long as the result doesn't break the rules for a valid Sudoku.
