Sudoku

Sudoku puzzles are puzzles in logic. Even though they can be constructed with any set of nine symbols, most are done with numbers because numbers are easier to work with.

The goal is to fill in all the blank squares with the digits one through nine so that each box of nine squares, each column, and each row contains each of the digits only once.

The logic for solving them reminds me, in some vague way, of playing minesweeper.

Here is a link to one site, where you can sample or purchase software that generates Sudoku puzzles on your PC.

Alternatively if you like the puzzles, there are plenty of Sudoku books available. These days, Ms. Eclectic seems hooked on this one (note: it is pretty cheap at Wal-Mart, too; geez, I wish they'd go on-line in Canada).
