The puzzle game of Mathoku is similar to Sudoku but with a mathematical twist. The goal is to place numbers from zero to nine in the spaces to produce the correct total for each row and column, utilizing the mathematical operations shown.

Mathoku is easy to learn and very addictive. Since the app utilizes random numbers to generate each puzzle, the number of combinations is almost endless (over 2 million games per level).

Users have the ability to save scores and view reports of those scores. Four more difficulty levels have been added to increase usability and enhance enjoyment of the game.

Created by a certified Math teacher, Mathoku can help sharpen a child’s arithmetic and mathematical skills as well as stimulate the logical mathematical minds of young adults. Fans of Sudoku, Twenty-four and Kenken will love it.

There are now nine difficulty levels and the ability to ask for a hint when needed. The mathematical rules of order of operations are reinforced with this app.

Really fun game

This is really a fun math puzzler. You really have to think and reason out the answers. I think kids would also like it and it would help them with their math facts. The hint feature is a big help, especially on the hard levels.

Great math puzzle

My students love this game! I use it as a reward and they don't even realize they are learning math because they are having so much fun. The harder levels really make you think. Thank you for using the proper order of operations!
