Just over a month ago, there was an article on Digg saying that the PerplexCity cube had been found. It sounded intriguing (especially the part about winning $200, 000) so I checked it out. Apparently, there’s a puzzle site called PerplexCity which involves a series of collectible trading cards, each with a puzzle. You log in, solve the puzzles, and get clues to the location of the final artifact.

Season 2 recently launched, and while I do enjoy solving puzzles, I seem to recall from childhood that collectible cards are a good way to sink a lot of time and money.

However, I’m very impressed by PerplexCity’s new Japanese Channel. Aside from having Sudoku puzzles (who doesn’t these days), it has a variety of other puzzles, some I haven’t seen before, and some that I have, including Kakuro. I haven’t seen many online implementations of Kakuro, but I think PerplexCity does a good job.

If you’re looking for a challenge, be sure to try a Ponturu puzzle. It takes me back to the good ol’ Graph Theory days of building connected bridge systems. Fun times!

    Dude, Ponturu is hot!

    And it’s funny that they call these Japanese puzzles. When Sudoku became crazy popular, I asked a bunch of people here if they knew Sudoku. No one had any clue. Then it started getting popular here a little bit after it was popular in America, though it has a different name here. Still, most people here don’t know what it is.

    According to Wikipedia:

    The modern puzzle was invented by an American, Howard Garns, in 1979 and published by Dell Magazines under the name “Number Place”. It became popular in Japan in 1986, when it was published by Nikoli and given the name Sudoku. It became an international hit in 2005.

    I think we Americans like it more as a Japanese puzzle than an American one. If some American hands you a bunch of squares and tells you to fill in some numbers, you’re like “stop talking to me you nerd.” But, if the Japanese are doing it, then it must be like Jiu Jitsu for your brain, “thank you sensei.”

    Plus there’s an article in today’s New York Times talking all about America’s “Japanese puzzle craze” and musing about which one will be the next big hit.

    Personally, I don’t think Kakuro could swing it. It took my parents a while to dig Sudoku, but they’re totally hands off to Kakuro because it’s has a perception of being more challenging.

    Bacarba is an interesting one on PerplexCity’s Japanese Puzzle Channel – it’s supposed to be Sudoku for people who don’t like numbers. But frankly – that’s the hardest one for me! Maybe it’s because I’m a number person. If anyone can solve one of those puzzles, let me know the secret! It eludes me.

What do you think?
