Sudoku was originally a Japanese game; however, some say it was Chinese. Born in the 18th century (about 200 years ago) it fairly recently stormed the world and can be seen everywhere (good things takes time).It's a fun puzzle dealing with numbers, but its not math!! No basic knowledge is needed, and anyone can play it. That is why it can be a game for the whole family. However, patience, time and concentration are necessary for addicts.It can be played anywhere, anytime and can be a great "time killer" (like waiting for a bus, at the beach, or for doctor's appointments).The Sudoku is a puzzle yet a sophisticated one that can keep you intrigued for long time. Perfection will come with practice.
