Well, I've finally succumbed, and have started playing sudoku, which was a fairly fun way to spend a snowy day in the house without actually doing things like cleaning or bill-paying. I've been printing and solving the "hard" level sudoku from http://www.websudoku.com/ in about 50+/-5 minutes, which is apparently well above the median time of 13 minutes or so by the average player. I don't feel like I'm a particularly slow player, and so the median time surprises me. But, I feel I've come up with a comfortable and enjoyable play method on my own that lets me reason out and solve these puzzles, and that's all that counts. What's the point of a game if it's no fun?
