I think this one is already on this site under a different name (about 60% sure). It's a good puzzle in any case.

I thought that I had rated this one b4-like sillywilly's thinking, maybe there's a double.

Broris can only be a liar because if he was truthful, his two brothers would be truthful - making the three other brothers liars - which can't happen as stated in the question. VERY GOOD Teaser! one of my favs cuz it took me a while to solve!!

This teaser seems a lot like part of the movie "Labyrinth." She encounters two doors, each with two characters, two lie and the other two tell the truth, and she has to figure out which door leads to the castle and which one leads to certain death. Good teaser none-the-less, a logical brain-buster.

"neither set of brothers consists exclusively of liars" is redundant. It can be deduced from Alan's statement.

Hoe can something that at first glance make no sense, then on second thought have possibilities of a solution be fun? This Teaser is difficult, boring and possess no true answer other then-
six brothers have the capacity to lie, and six brothers have the ability to tell the Truth.

This was challenging, but so fun! I love logic teasers--when I finally solve them, I feel like I really accomplished something. And my brain feels stretched!

If you can unscramble your brain, it becomes fairly easy.

For me the second line gave the first big clue, after that it became easy as long as you didn't become too confused. Loved it.

this is a basic logic grid puzzle. if you like this kind of puzzle just google "how to solve a logic grid puzzle." if you draw out the grid, it only takes a minute or two to solve.
