### Re: Who has the purple door?

That devious thought of mine didn't quite work out as I'd hoped, but I was able to use some of it to make a few alterations that I think add more variety and difficulty.

I've checked the puzzle from scratch and it seems to be ok.

Please check it too, and let me know what you think.

### Re: Who has the purple door?

Oops!! Looks like that last version has a loophole that leads to an early solution!

I discovered the shortcut while trying to see how far I could go without a certain clue in case I could alter it to improve the puzzle.

I'll check the version in post #44 to see if the problem occurs there too.

Making changes is fraught with danger!

EDIT: I think I've just found a fix for that loophole, and also a superfluous clue related to the fix. I'll check it all out, but I'm busy with something else until tomorrow.

Great puzzle. Finally managed to solve it.

### Re: Who has the purple door?

Just out of curiosity, which version did you use? ie, from which of the posts on this thread.

You've probably noticed from all the posts here that the puzzle is still in a state of refinement, and we haven't quite got there yet with a final version. Hopefully the version you solved was one from which pRo9aMeR (the OP and composer) and I had ironed out most of the problems.

Did you notice any problems (eg, ambiguities) with the one you did?

Thanks for your feedback...it's nice nice to actually hear that someone has tried the puzzle!

Btw, would you like to post your solution? If so, please use the 'hide' box.

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)

### Re: Who has the purple door?

I used the one in the post 28, which I believe was the refined version.

Hi pRo9aMeR,

I can't think of any more improvements, so (hopefully) this will be my last revision.

Sorry it took so long to get to this point, but I kept on thinking up new things to include and finding errors and loopholes to fix...etc.

I think it's the most difficult version to solve yet and I'm very happy with it now!
