Do you like Sudoku? How about KenKen (or is it Ken Ken)? Or simply looking for that next game to get you brain going? Then give Mathdoku a try! Mathdoku Challenge! brings an exciting new twist to Sudoku. Step up to the plate and solve problems with your math skills. Face challenging puzzles of varying sizes, leverage the hints you are given, and use logic to find the solution. Mathdoku will stretch your mind, wake you up, and keep you on your toes. Play as many puzzles as you want! Each day, you get even more puzzles to play. Or purchase a puzzle pack to keep the fun going. Puzzles are divided into cages by grouping cells together. Hints for a cage are composed of a target number and an operation. Combining the cells in the cage using the mathematical operation must reach the target number. A number can only be used once per row and column. Use this limitation, hints, and unit cells to find the solution to the puzzles.

OUR NEWEST PACK – CLASSIC VOLUME #2! Classic sudoku is where it all began, and there is still lots of skill to be deployed to solve classic puzzles, and new techniques to be explored. Nikoli, the Japanese puzzle house, named and popularised sudoku from 1984, and we have commissioned 20 puzzles from them for this Classic Sudoku 2 app. We have also created 20 ourselves, and sourced 20 more from Sam Cappleman-Lynes, the brilliant British sudoku expert. The result is a wonderful 60-puzzle pack which will delight and challenge you. -------------------- Welcome to the brand new Sudoku app from the most popular Sudoku channel, Cracking The Cryptic.
