Have you ever solved a Sudoku puzzle? Do you think you might enjoy solving Sudoku puzzles?
Sudoku is a pencil puzzle with simple rules. It's so beautiful, you might fall in love with it. Perhaps you are fascinated already by Sudoku and are yearning for more. If so, I want to ask, do you know how to recognise a truly good Sudoku puzzle?
Let's consider a puzzle that has been made using a computer program. If you are a reasonably experienced solver, you might wish to tackle it. You will soon discover that making a start is difficult. There are no cells in which to place a number using straightforward techniques.
Computer-generated Sudoku puzzles are lacking a vital ingredient that makes puzzles enjoyable - the sense of communication between solver and author. The best Sudoku make you concentrate, but aren't stressful. They are absorbing, never boring.
Good Sudoku authors are always considering a solver's feelings. Can a computer program do this? Can a computer take account of the way a solver thinks?
I am concerned that poor Sudoku, which take no account of solvers, will overwhelm us - and the joy of pure Sudoku will be lost forever.
Sudoku could be your friend for life. I must ask you, therefore, not to touch computer-generated puzzles. Take pleasure in the properly crafted Sudoku puzzles.
