This week I have some good news, and some bad news. The bad news is I haven't put up the solution to the venerable Cannonball Competition, and I'm about to go on vacation.

The good news is that I pulled out an emergency new puzzle to give everyone something fresh to cogitate on.

I will be on vacation for two weeks, during which time there will be no updates.

Incidentally, a new feature was added with the last update, and now visitors can rate all solved puzzles and view all puzzles to date sorted by popularity.

Until next update,
