puzzle design challenge |
Brian Kwon-Tom Obsessive Puzzles: 4884 Best Total: 9m 6s | Posted - 2007.04.27 04:36:51 Since there are a few people creating puzzles now, I thought we might have some fun challenging each other to design puzzles. My first idea relates to puzzle #84, where there's a big 6x6 square in the center devoid of clues. I haven't been able to make any bigger than that, but perhaps you can. (Or perhaps you can show why it's impossible.)
So this is my first puzzle design challenge, to create a puzzle with the largest square or rectangle in the middle that's devoid of clues. This is actually trivial in one sense, as the following illustrates:
So we need to add the condition that the loop actually goes through this space. We should also require that the width and height of the rectangle are at least two:
Unfortunately, I'm going to be out of town for a couple of weeks, but I hope some of you will have fun with this and I'll be sure to catch up when I get back. |

The non-close property of the puzzle has substantially more power to push into empty spaces then I would have guessed. |

Just to show the rules will always stay a bit trivial (and thereby claiming victory ). Here are some patterns that can be stretched as far as you want to; just insert ones. Yes it is bending the rules a little, but the loop travels through the empty rectangle and they are 3 high(so at least 2). So empty rectangles of 3 by infinity.

As far as i can see, this has no solution ...
... and this one has two. |
Para Kwon-Tom Obsessive Puzzles: 1923 Best Total: 19m 28s | Posted - 2007.06.13 22:04:02 This should work
What is the other solution? Maybe is missed something.
These patterns were just a joke.

Naivoj Kwon-Tom Addict Puzzles: 314 Best Total: 33m 50s | Posted - 2007.12.27 16:49:40 By extending Jankonyex 121 wall design 5x7=35 squares are cleared.
I don't believe it can be stretched further.

Yes, but I can only get one more row for 5x8-1=39 squares. Though it is a different problem.

Naivoj Kwon-Tom Addict Puzzles: 314 Best Total: 33m 50s | Posted - 2008.01.02 07:15:59 Brian, I am curious to know how you came up with your neat puzzle #84. Did you wrote a specific program that turns up with it, or did you sketch it yourself? |

I did that one by hand. All the others have been computer generated. I've never been satisfied with the ones done by hand (except for #84). |

The fact you did this by hand is remarkable. Writing a program that come up with this will be impressive too, but not as much in my opinion. |
