As you know, "Number Place" is the famous puzzle in a world. It is known as "Sudoku *1". Therefore, we do not explain about the rules. If you do not know about it, please search the word on web.


"Diagonal Sudoku" has one more rule than Standard Sudoku. You must fill all empty cells so that the numbers appear exactly once in each row, column, diagonal and block.

This app has 3 board sizes. These are 9x9, 8x8 and 6x6.


In this application, we adopted a new input method "Thumb One" for a smart phone. When you are working with a smart phone with one hand, you can enter the answer and pencil marks in just thumb of one hand.

If you are interested in "Thumb One", please see this movie.
