great puzzle - this is what this web site should be for - hard puzzles, not those colourful crappy things with too many spaces filled in that there is no skill needed - this is a PUZZZZZZZZLE site, not a picture site.

Me encanto, la verdad es que aplicando simple logica se resuelve y ya entendiendo el sentido se va resolviendo solo, felicidades!

Thanks.

If you're interested in my survey, it's here: http://webpbn.com/survey/

If you want test data for your solver, or want me to test it against the others, I'm happy to do so. It's getting to be a pretty competitive business though.

I actually did the comparison of different solvers on variously scaled versions of this puzzle and wrote it up.

It's here: http://webpbn.com/survey/dom.html

I think this is a fun thing to put up as a challenge to designers of solvers.

I enjoyed this one, because the "aha!" came fairly quickly. If I hadn't found the solution right away, I would probably hate this puzzle. ;)

Dito #13.

I used to say "I don't like puzzles of nonsense image", but this puzzle demolished my theory and changed my way of thinking, because the kind of logic required to get the solution makes it a very good clever puzzle.

Here's a link to a PDF of an Australian research paper called "MDD Propogators with Explanation". On page 17 you'll see a picture of this puzzle. They can solve up to size 20, which is way better than I've seen anyone else do.

So this puzzle is now officially part of SCIENCE.

It's also an "Eyeball Bender" of a baseball.

Great puzzle! I'm still struggling to get beyond line logic and this one helped me a lot.
#18: Brian Bellis (mootpoint) on Dec 27, 2018
I'm sorry to say that I "intuited" the solution and solved in about a minute. This was obviously meant to be a fun and tricky solve but I just gave it a lucky guess.
