As I mentioned in my previous post that Sudoku is a logical puzzle. There is nothing Mathematically about Sudoku. However there are many Math Sudoku Variations where one need to use Mathematically operations like addition, division, multiplication or subtractions. Killer Sudoku is one of the famous Sudoku variations which uses addition operation. Kakuro puzzle again uses addition operations. We have even one variations name SudoKakuro which mix both Sudoku and Kakuro.
Anyway coming weekend from 17th to 19th January, 2015 there is Sudoku Mahabharat Math Variations contest by Prasanna Seshadri. It contain very interesting Mathematically variations in Sudoku. Most of these Sudoku variations are already published on this blog.
