<mm> An incredibly ingenious invention of a "count-down mechanism"! Great job, radiant! :-) |

<radiant> Believe it or not, it's not the norm to expect 10 new levels every day around here.
You can try the levels I put up last week if you want something to do. |

<radiant> Oh, nice catch on that one!
<gary> Tom, please delete this level as this is a duplicate of "Destination Death". |

<radiant> At least the minors will feel somewhat less neglected now. |

<radiant> Might as well keep up the tradition of everyone who's figured this out leaving a comment of some sort. |

<radiant> Maybe if it were actually spoiling anything, instead of vaguely discussing the construction of the level.
If one of us were just going to state the key sequence, clearly that gets a spoiler. But other than that, is anyone really going to take these bits and pieces and get the second solve time down from 6 months? (If you are, good for you.)
Besides, even if the outcome of my non-poll is to reveal the sequence, it won't be by way of comment.
<John Lewis> Um, excuse me, gentlemen...but shouldn't these comments be marked as spoilers? :)
<pieguy> i believe solutions are automatically optimized before upload, so any back-and-forth running would have been taken out. plus, that still would have revealed the parity of the bits in the key. it's not much, but when you want a cryptosystem to be secure, any leak of information is bad.
your extra row idea would be great if you wanted to do a hash instead of a cipher. as far as i know decrypitng 0 isn't any easier than decrypting a random plaintext (but then again, i thought it would take a million years to solve this, so what do i know?)
<radiant> I checked the original solution and it was the same as what I found. Whether there are any other solutions or not, I stand by a 10-6-9 rating because to me "rigidity 10" means only one successful possibility at every move, and at the least it's possible to run backwards here before processing the cipher. Even if you didn't use the neat broken block mechanism, you could have run back and forth in place to delay the solution to 1142, and been nearly as effective at disguising the bit count. Probably even more effective at getting people to try a bunch of guesses before they gave up.
<pieguy> i'm mostly curious if the key you found was the same as the one in the original solution (someone gave it a rigidity of 9). was it your ideas from your april comment that ultimately led to the solution?
<radiant> If you really wanted to be funny, you could have added another row or two of remotes along the top and had a bot there to flip some bits of the text after step 1008, so as not to be constrained by designing to a single predetermined plaintext. Just enter in your key of choice, run the cipher to see how it turns out, then put in the requisite bit flips after the fact.
How about I take a poll on whether I disclose the key to finally put this level to rest, or keep it as a challenge for anyone who dares to follow...then just ignore the results and replace it with a roll of a 30-sided die. Sure I could just use a coin, but bigger numbers and more complexity are good, right?
<pieguy> holy cow! you actually solved it?!?! i'm impressed. how about a breakdown of cpu time/memory usage?
tom, would it be appropriate to move this level into "very funny" or something similar? i should have asked for this sooner. |

<Tom 7> Wow, very nice technology!
<John Lewis> This is simply brilliant.
<gary> The timer ticks when a block is pushed. Nice. |

<mm> True. I think great levels should not be ruined. But radiant might not have been aware of this! So I'd forgive him anyway!

<Bekah> This was fun. Once I realized what the problem was (how to take a knight through every square of a chessboard, only visiting each square once, and ending where you started), I just pulled out my graph paper and pencil. When I had my solution, putting it into the game was easy. Thanks for the challenge. |
