Congratulations!
There's no intentional randomness in the recording. The random artifacts are probably caused by a combination of the voice generator and the mp3 encoder.

Congratulations! Indeed, the message is encoded using a Rice Code. When I made the puzzle, I wasn't sure how difficult it would be to solve. It took a while for anyone to crack it, it I guess it was a bit harder than I planned. It's interesting to see that one of you got to the answer without any kn...

Indeed, the intention of the challenge was to figure out that it was based on the convergence of the infinite series 1/1 - 1/3 + 1/5 - 1/7 + 1/9 .... This is often called the Leibniz formula. You can find a proof for the computation at: http://en.wikipedia.org/wiki/Leibniz_formula_for_pi The sad thi...

Thanks tails,

indeed, I messed up the word ANSWER. Thanks for the fix. We'll update the challenge on the server.

Congratulations, gfoot, you're the first to solve that puzzle!
I'm really happy that you did, because Adum keeps telling me that my puzzles are too obscure for people to solve. You just proved him wrong. Thanks.

You're right, the documentation was wrong. I've fixed that on the web page.
Thanks for spotting that.

Congratulations to Allosentient! He is the first prize winner for having reached and solved the "It's a very small word!" challenge. But this is not the end... we are continuing the prizes for the Challenge section, and we will continue adding new challenges as time goes, so stay tuned and...

This is a known problem with the map viewer: if you're not logged in, you won't see any of the points on the map. Make sure you're logged in, and then go back to the challenge map, and you should see the points (you might have to reload if you had already visited the challenge map page from the same...

I've looked at the answers you've submitted, and I can tell you that they are not being rejected because of a rounding error or a syntax issue. The values are pretty far off. Maybe I can try to give an example to clarify what's being asked: The first player plays in the center. After that, the secon...

That might be because you were not logged in. The flash app uses an HTTP request to get the challenge data for your account. If you're not logged in, the server won't return the data, but the app is not sophisticated enough to display that error condition. You can checked if you have logged in from ...

Indeed, 'Anyboy Out There' is solvable... I just checked it.

The map viewer is a flash app written with Flex 3.0. As such, the browser version should not matter much, as long as the flash plugin works well. Can you describe what problem you're having exactly?

You could play those by hand if you've got very good hand-eye coordination and a lot of patience. However, I recommend to lazy people, like myself, to find a way to 'cheat' the game. There are several ways to do that. Looking at which language the game is implemented in might help you figure out whi...

In general, crypto challenges don't have, like some other challenges, a clear indication of what you're supposed to do. They all behave the same way, however: what's on the challenge page (text, image, sequence, whatever) can be decrypted into a short answer, or answer description (but be aware that...

Nice to see that you have a C# implementation of the VM. Maybe you can post it to share with others?
