App Review: Sudoku Free is a time management app that helps you keep track of your daily goals. It also helps you learn how to manage time more efficiently. It offers the same addictive quality of playing Sudoku that made it the number one app in the world. As with most other apps, there are a number of ways you can "accumulate" points. The only difference is that you do not have to solve a puzzle to gain points.
You can simply go over the challenges listed on the app and complete them to gain extra time, and eventually gain points. You will be able to see the point values of every challenge, and at the bottom of the app there is a list of all of the levels you've successfully completed. And because the app is free, you should really take advantage of it, especially if you like managing time and doing tasks with a challenging feel.
