If you desire to develop your brain logical power, I recommend sudoku puzzle game for you. Sudoku is quite simple game that 4 or 5 years old kids can play it. The standard sudoku is designed with 9×9 grid. The objective is to fill blocks with all digits from 1 to 9 on each column and each row. The well-designed puzzle has only one solution.

Sudoku was introduced to Europe and North America at end of 19 century. And this game become more popular in USA from the beginning of 20 century. More sudoku mobile game and online game was developed, however, more sudoku players perfect playing on paper rather than playing it on smart phone or PC. There are some reasons players told me.

1.Playing on paper is their habits.
Despite there are thousands of sudoku Apps on App Store, Christina told me that she plays sudoku from 20 years ago and there`s no smart phones at that time. It is pretty easy for her to make a remark on the corner of paper, it is not convenient to take notes on smart phone. It is really so hard to change their habits in short time.

2.Do it on paper is better for eyes.
Susan is a mother and she has a 5 years son. To protect her son from huge information interface, She controls her son access from digital devices and she told her son it is better for his eyes. So many parents like Susan limit their children to playing games or watching video at a long time. The smart phone or tablet`s screen could hurt child and teenager`s eyes.

3.They hope to play sudoku with families and friends.
David is the university study and he told me that he always play sudoku with his roommates. Sometimes, they hold sudoku game match in campus community. They can`t play sudoku against their friends on Apps or online. While they a tough challenge, they will work together o solve it.
