While I was experimenting with the options settings in JSudoku, I reset all of the options to the defaults. This means that JSudoku autogenerates a puzzle (of whatever type was used last) each time the program is started. I decided to keep these puzzles and post them for your enjoyment and comments.
I have no goals as to difficulty level (other than that JSudoku has to be able to solve them in less than 5 minutes). They're autogenerated, so in terms of difficulty and techniques, they're like a box of chocolates--you never know what you're going to get.
I will also try to rate them according to Børge's system and post a list of techniques as generated by JSudoku, but I have gone only as far as Step 3 in
Børge's technique analysis.
