Beginners tutorial: 4 x 4 grid Sudoku

If you are just getting started you might want to have a look at this site. It shows (with pictures) how to solve a simple 4 x 4 Sudoku puzzle.

Which is a great way to start, because having only 4 numbers makes it much easier to see what is going on, and all of the principles can be applied to the usual 9 x 9 grid.

Enjoy!
