Here in Tuscany, the Munger family has rented a vacation house for a couple of weeks. Typically the day’s biggest event is preparing dinner. Otherwise we generally just lounge around the house, admire the view, read, or converse over a glass of wine.
Today we thought we needed a project, so Nora and I decided to try and make our own Sudoku puzzle. It’s actually more difficult than you might think. You can’t just randomly fill in squares in a grid to make a Sudoku puzzle that works. Then it’s another challenge to create a set of clues that will result in one unique solution.
After several hours’ work and several sheets of scratch paper, we think we’ve come up with a puzzle that isn’t trivially easy.
But we’re rather close to the project, so perhaps the puzzle we made isn’t challenging enough. Or maybe we made a mistake and our puzzle doesn’t have a single solution. So we decided to put our puzzle to the readers of CogDaily. Here’s what we came up with:
Unfortunately we’re not smart enough to create an interactive online puzzle, so if you’d like to try it you’ll have to print the puzzle out and fill it in by hand (click to open in its own window for easy printing!). Once you’re done, let us know how we’ve done in the poll below.
If you’re a Sudoku novice, the instructions are simple. Just fill in the remainder of the grid so that every row and every column has every digit from 1 to 9 with no repeats. In addition, every bold-outlined 3 X 3 square must also contain each digit from 1 to 9 with no repeats.
Do you have any suggestions for how to improve our puzzle? Have you ever tried to make your own Sudoku? Let us know in the comments.
