Sudoku is a very popular game nowadays. Most people play it. We did a survey among our friends and relatives to see the popularity of the Sudoku game. We found that most of them have played it but some had stopped already. Here is a chart showing the percentage of people that play Sudoku.
We also wanted to find where the people get their Sudoku grids from. We found that most people get their Sudoku grids from newspaper/magazines. And the others get from books, teachers, internet, machine etc. We think that maybe it's because the Sudoku game is now introduced into the newspaper and magazines, more people tend to play the game.
There are mainly three difficulty level for Sudoku games: Easy,Average and Hard. People can choose the one that best fit theie own level. We found that most people usually do the easy ones while some try to all the levels. We think it's because most people are beginners and they haven't pratised enough to do the hard ones.
