Last month for puzzle.jp

One of my favorite websites, Puzzle.jp, is closing at the end of July. This is normally a subscription site, but they are opening up the members' content to everyone for the last month. Hopefully I can find a similar site to replace it. My favorite puzzle on that site is Slither Link, but I like all the other puzzles, too, with the exception of Kakro, which I've never found very interesting.
