The browser version of "Sudoku Kyo" has posted a large number of good questions that can be solved without provisional problems, and has been evaluated by many users by dividing them into small levels from simple problems to difficult problems.
Furthermore, we succeeded in creating a super-difficult problem by creating an original AI that researched Sudoku. Most of the difficult problems sold in the general market can be solved only with basic techniques, but the difficult problem of "Sudoku Kyo" is to use the swordfish twice and overturn the difficult problems of Sudoku such as XYZ wing. We have prepared a series of super difficult problems.

[Answer to the application explanation problem]
Since [4] is placed in one of the four cells of the image in the X wing, you can delete the memo number [4] in [Row 3 column 3] [Row 3 column 7].
The Y wing is made up of the pink squares in the image. When the pink square on the upper right is [1], the pink square on the lower right is [9], and when the pink square on the upper right is [5], the pink square on the upper left is [9]. I can't put it in.

【problem】
Of course, there are only 300 new questions up to level 1-8 that can be solved without duplicate solutions and without temporary placement.
In addition, we have added 300 new questions for difficult Sudoku up to levels 1-8.

[Difficult question Sudoku]
This is also a problem that can be solved logically. However, technique is required, and if it is a general difficult problem collection, it is about level 1-2 of difficult problem Sudoku. In other words, it should be a difficult problem that you have never experienced. A super difficult problem that looks easy and cannot be solved. Please try it.

[Comfort]
The usability is the same as the browser version and it is easy to use. Memo function and coloring. Start over. There is an unlimited hint function, and the solved time is also recorded.

[Slowly offline]
Sudoku Kyo APP can be solved slowly offline. It can be used as a companion for a short gap time or commuting to school, and you can also enjoy the difficult problems carefully (packets are used for displaying advertisements).
