wow phrontister! I'll have to give the puzzle ANOTHER spin~~ look forward to its "refurbishness" smile

#2 Re: Puzzles and Games » Who has the purple door? » 2013-02-26 16:10:11

Shivamcoder, I'm glad you enjoyed the puzzle!  Like phronister said, the puzzle is not yet perfected to our liking but the second most recent version (post 44) is the best one we've come up with.

Phronister, yes, the most recent version does allow for a slightly premature solution.  I'm gonna stick with the one before that for now.  I'm updating the OP so that it shows that one (from post 44)

#3 Re: Puzzles and Games » Who has the purple door? » 2013-02-24 18:09:59

I'm happy with it too so if MIF would post it on the website, that'd be fantastic!

And thank you phronister for helping make this an awesome Einstein puzzle!

#4 Re: Puzzles and Games » Who has the purple door? » 2013-02-21 18:32:10

You're right, if we take it out then some ambiguity arises which throws everything out of whack.

I guess I'm fine with this version.  I've solved this so many times, it doesn't seem that hard anymore!

#5 Re: Puzzles and Games » Who has the purple door? » 2013-02-20 19:08:54

Excellent work phronister!
I've been sick the past week so haven't been able to do anything.  But I did finish working through your latest version and it seems legit!  Just a thought, what would happen if we take out clue 31?  I'll try and work it out and see what happens.

#6 Re: Puzzles and Games » Who has the purple door? » 2013-02-13 22:04:02

"argh" is how I spell the sound that Charlie Brown, one of the characters from the classic comic "Peanuts", frequently blurted out when he was frustrated.
It could also resemble the sound of a pirate, but with more of a frustrated tone.

Five minutes would be enough if I didn't also have to prepare materials for the following class tongue

#7 Re: Puzzles and Games » Who has the purple door? » 2013-02-13 19:52:19

Another problem with changing the title is that now the 10th color, purple, is not metioned at all.  I see what you're saying but I'm trying to work on the in the 5-minute breaks I have inbetween my classes, that is to say that I don't have the time to devote to it right now.  I'm also in the process of moving so outside of work I have no time.  ARGH!

#8 Re: Puzzles and Games » Who has the purple door? » 2013-02-11 21:33:10


You've been busy the past few days I see!  I see what you've been saying and I'll give your newest version a go and see what turns out.

#10 Re: Puzzles and Games » The King and his Four Cities. » 2013-02-05 19:56:57

I did slightly misunderstand the question...But now I'm confused.  Why wouldn't a simple "X" be shorther than the ">-<"?  I 'looks' like it takes longer to travel that way...

#11 Re: Puzzles and Games » Who has the purple door? » 2013-02-05 19:51:51

I updated the OP with the above post's info.  Should be ready for a spin Phronister!

#12 Re: Puzzles and Games » The King and his Four Cities. » 2013-02-04 21:54:03

I think I'm oversimplifying it, but wouldn't a direct road to and from each city suffice?  The roads would make the shape of a square with an "X" in the middle.

#14 Re: Puzzles and Games » two possible solutions for Who Lives in the City? Einstein Puzzle » 2013-02-04 21:31:47

Phronister, I just checked your newest version that includes curly hair.  It works out!

And I'm updating my Purple Door puzzle...I had the same double-solution problem, but thanks to some students, I got it squared away I think.

#15 Re: Puzzles and Games » Post more bigger numbers » 2013-01-29 20:42:54

I've never seen that connotation before...

Could someone explain what "2->2" means?  How do I read it?  How do I evaluate it?  Where is it used? etc.

#18 Re: Puzzles and Games » two possible solutions for Who Lives in the City? Einstein Puzzle » 2013-01-13 06:06:19

well done phronister!  Now there is one and only one solution!

I got the same answer as Bob as well.

One thing that has bugged me about this puzzle, though, is the fact that curly hair is never mentioned in the clues.
I'm not gonna try and mess up what has finally been cleared up now.  Maybe in the future when I'm bored...

Nonetheless, phronister GG!

And a quick question - Has anyone else completed my "Who Has the Purple Door?" puzzle besides phronister?
I had updated the OP in that thread with the (hopefully) final changes but there hasn't been a response.
phronister, maybe you could double check that it's still good enough; I'd like it to be posted on MIF to see how my puzzle fairs in the rest of the world.

The puzzle posted on MIF in its current state has two possible solutions.

I don't have time to explain here, but the fork in the road begins after clues 1,2,4,7,8,9,10,13,14,15,(16),18 have been put in place.

#23 Re: Puzzles and Games » Who has the purple door? » 2012-12-08 18:38:18

MIF, I guess that this puzzle is in it's final version for the time being.  Would mind putting it on the website?  I want to know if someone other than phronister (gj again btw!) can solve it!

#24 Re: Puzzles and Games » What words can you make with julianthemath? » 2012-12-08 18:34:14


in hindsight, I should've typed them left to right with commas instead of up and hard to keep scrolling back and forth the check for repeat words

#25 Re: Puzzles and Games » The Garden Problem » 2012-12-04 19:31:25

I've done all of the other Einstein puzzles on the website but this one still eludes me as well, bluemist.

I posted an Einstein puzzle that I made a few months back.  To my knowledge, only one person here has solved it.  It's called "Who has the purple door?"
