Mathdoku Challenge! vs MathDoku

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.

MathDoku turns a quiet ten minutes into the best brain workout in your day. Inside every grid is a small, elegant arithmetic puzzle (also known as Calcudoku): fill each row and column with the numbers 1 to N without repeats, while the cells inside each outlined "cage" combine — using add, subtract, multiply, or divide — to hit its target. No guesswork. Just clean, deductive reasoning.
