Online Puzzles

I'll put some of my puzzle stuff up here sometime, but for now, you can go visit some of my favorite puzzle sites. I try to keep this a "best in class" sort of list instead of putting every site I've found in.

• Variety Sites (see table below):
  • Conceptis: You'll need to sign up and have Java and Flash working (and pop-ups allowed for them?), but these are good. New puzzles every Friday morning (GMT). The recent overhaul allows saving and has more puzzles you can play online. At the front page, there's other stuff too (including the T-shirt contest).
  • Indigo Puzzles: Free sign up. The online tools have nice hints, but they could be easier to use.
  • Otto Janko's Puzzles: They're in Austria, so it's in German (Google English translation), but there's a lot of nice stuff here.
  • Logic Games Online: Free nurikabe but they're all small and easy. It's a nice warm-up in the morning, but nothing compared to monsters they have at Nikoli.
  • Nikoli (nee puzzle.jp): I'm a subscriber, but even if you aren't there are some sample problems, and fun contests there to keep you for a while. You might also check their corporate site, especially for instructions on their puzzles. I find their interfaces (other than sudoku) to be overall the best, though their "Check" feature is universally inadequate.
  • Puzzle Mix: He's got a few that are hard to find online, but his interfaces need some work. I've only recently signed up, so I'll know better after I try it more. He also has sites dedicated to specific puzzle types, but you have to sign up, and then he has very few free puzzles. You're probably better off suscribing to Puzzle Mix.
  • Puzzle Express: Less what I'm looking for, but worth a look. The battleship puzzles have an excruciatingly bad interface.
• Slitherlink:
  • Kwon-Tom Loop: Daily Slitherlinks with an OK interface.
  • Hirofumi Fujiwara's Number Lines: Slitherlink puzzles with an OK interface. Not as good as Nikoli's by half, but better than many I've tried. He only has a small set of them, but the hard ones are really hard.
  • Puzzle Loop: more Slitherlink. I can't stand the look of the puzzles- I find them very hard to read- and the hot regions are way too small, making them hard to click on. Go try Nikoli's to see what I mean. The reason it's good is because it'll make as many puzzles as you want.
• Bridges: Don't like the interface as much as Indigo's (and I'm not crazy about his either), but this, like Puzzle Loop will let you make as many puzzles as you want.
• Griddlers: Need to sign up, but then you can do several nonogram variants until your fingers fall off.
• Hitori Conquest: Hot spots are too small, but it's OK.
• Daily Kakuro: Their user interface is kind of crappy (they'll sell you one that's allegedly better), but they're decent puzzles and the list of possibilities can be useful to beginners. (The assistant at Indigo is much better, though!)
• Light Up: Akari, though the interface is clunky next to Nikoli's, that's not the worst part. The puzzles are crap (like next item). but at least you can generate as many as you want.
• Nurikabe: Same caveats as Puzzle Loop (well except there aren't any at Indigo). The puzzles are tedious because the numbers are so small.

Sudoku?

"But what about sudoku, ab, or are you too cool for that?" No, just too cool to play online. I can't recommend Sudoku Susser enough. I do all those there. It can fetch some from the web, or you can import them from graphics(!) or text from web sites.

And RTFM. Seriously. Sudoku Susser has made me an inhuman sudoku-solving machine, and it's because I read the fine manual.

Crosswords

I don't like doing crosswords online. Really don't. A lot. And many of the puzzles you can get aren't very good. (Automation has allowed the talentless to get farther than they should.) Here are some that are good and printable. Some have .puz versions that work in Across Lite, which will let you print them (or do them on the screen). Or you can do them online if you're one of those people:

• Eugene Sheffer's Daily Crossword (or online): Today's Crossword from King Features Syndicate.
• Daily Coded Crossword: A cross between a cryptogram and a crossword.
• The Guardian: I haven't automated turning this into a .puz yet, but I know how.
• The Sydney Morning Herald: A daily cryptic. (today's .puz) I think this is the most consistent and best free daily I've found online, but I'd love to find better.
• The Herald: A daily cryptic. (today's .txt) They do not follow the rules as well, but it's a little easier when they do.
• Merl Reagle's Sunday Crosswords: the most recent four of his puzzles are available as PDF downloads or for doing online (or as a .txt).
• Matt Gaffney's Weekly Crossword Contest: A crossword with a puzzle in it is posted Friday. Send him the answer by Tuesday and you could win one of his books. (Fun anyway, of course.)
• The Puzzler: The Atlantic posts a variety cryptic every month. I hear they don't print them in the actual magazine anymore, so no sense buying it. The archive goes way back (May 1997 at least), so this can keep you busy for a while.
• Ray Hamel: He's got a pretty good list of puzzles all over- I'm hoping to cherrypick the best out for this list.

Big Table of Puzzle Sites

Puzzle Types: The puzzle type names in the column headers link to articles about those types.

Registration: most sites require you to register to get full access. The advantages are that you can usually save your puzzles and keep records (not Conceptis, unfortunately). All the sites have some puzzles available without registration, though Conceptis has very few. Nikoli is 550 ¥/month, the others are free.

Availability: p means the puzzles are available only for printing. o means you can play them online (or print them, I suppose). I'd rather do most online, personally.
