New puzzles coming…

I’m working on some new puzzles and thought I’d give you a preview…

For the kids, I’m adding a new collection of mazes in a variety of animal shapes, such as this elephant.

For the non-kids, I’m adding some new logic puzzles, based on my favorites from Nikoli, the Japanese publisher that popularized Sudoku. One of those favorites is Slitherlink, which you can read more about, on Wikipedia.

Some of the software I’m using to generate these puzzles is based on Simon Tatham’s Portable Puzzle Collection, which contains a number of Nikoli puzzles. I modified Mike Pinna’s Slitherlink algorithm to produce symmetrical puzzles, which I prefer, and to minimize the number of clues per puzzle.
