Sudoku is a puzzle made up of 9 x 9 squares. The entire sheet consists of 9 squares, each made up of 3 x 3 squares. There are certain numbers that are present in these squares. The whole aim of the game is to fill up the rest of the empty squares in such a way that each 3 x 3 square must contain the numbers 1 to 9, all occurring exactly once.
Anyone who can count 1 to 9 can play this game. Well, it's not very difficult to solve, in the end it all boils down to speed. Everyone gets the answer in the end (for the intellectually challenged, the answer is the numbers 1 to 9 not necessarily in that order). In the end, what matters is how fast you manage to fill all the squares in the correct manner.
Tips to Play Sudoku Puzzles
One major mistake that most amateur sudoku players make is to blindly trust their instincts. Yes. If you 'feel' that you need to put a 1 in that particular square, it doesn't mean that you blindly do so. Such people just tend to rush through the game trusting their wits, sometimes adding a number without cross-checking if it's in the right place.
Keep At It
Once you start keep continuously scanning and checking for possibilities. That's the best part of this game - it's natural for one thing to lead to another. So once you've scanned a particular row or column, then check for that 3 x 3 square. See which number is missing.
