I need some mind-bendingly difficult brain teasers. <br /><br /> I used to tackle these all the time back in high school, and my passion for them was recently rejeuvenated when I picked up Professor Layton for the Nintendo DS. I've been searching online, but all I come across are sites with crappy little riddles and math problems. I need some big guns. If you have any really great ones or know of a site that catalogues a trove of them, please post them here.post:ask.metafilter.com,2008:site.94764Mon, 23 Jun 2008 07:11:13 -0800Christ, what an assholebrainteasersriddleslaytonpuzzlesBy: Jaltcoh

This had me and several of my friends swearing for several days:<br>
<br>
<a href="http://thinkzone.wlonk.com/MathFun/Triangle.htm">The World's Hardest Easy Geometry Problem</a><br>
<br>
I sketched it out in crayon on the paper tablecloth where we were eating, which lead to a rapid proliferation of triangles across the table.<br>
<br>
I gave up; there's apparently a solution, although I won't link to it, since that would spoil the fun...comment:ask.metafilter.com,2008:site.94764-1384499Mon, 23 Jun 2008 09:11:47 -0800kotharBy: martini

Does anyone have more story-related ones? The math ones require more pencil-paper treatment. I'd like ones my friends and I can hawk over during a cocktail party.comment:ask.metafilter.com,2008:site.94764-1384633Mon, 23 Jun 2008 10:55:38 -0800Christ, what an assholeBy: Hlewagast

It's funny... I just did a search for a puzzle I solved, and forgot about ("The Bridge"). And found it (and more) <a href="http://www.puzzle.dse.nl/teasers/index_us.html">here</a>. <small>Currently stuck on "Alphabet Blocks".</small>comment:ask.metafilter.com,2008:site.94764-1384842Mon, 23 Jun 2008 13:20:56 -0800ObscureReferenceManBy: peacheater

If you like logic puzzles I cannot recommend Raymond Smullyan's books more -- <a href="http://www.amazon.com/exec/obidos/ASIN/0671628321/metafilter-20/ref=nosim/">What's the Name of this Book?</a> and <a href="http://www.amazon.com/exec/obidos/ASIN/B000VZMCBY/metafilter-20/ref=nosim/">Alice in Puzzleland</a>. They can be hard to find since they don't seem to be in print anymore but I worked through all the puzzles as a teenager and found them really mind-bending.comment:ask.metafilter.com,2008:site.94764-1384912Mon, 23 Jun 2008 14:13:46 -0800peacheaterBy: smackfu

These three have an underlying mathematical foundation to them, but also can be solved using an intuitive process as well. I've found that the chicken mcnugget one is especially good with kids and computer scientists.<br>
<br>
Chicken McNuggets come in sizes 6, 9, and 20. What is the largest number of McNuggets that they cannot serve you? For example, they can serve you 26 (a 20 pack and a 6 pack) but not 25. (Or is there a largest number?)<br>
<br>
Suppose you have a coin that may or may not be 50-50 chance of heads and tails. What can you do to still use the coin and make it 50-50?<br>
<br>
Suppose you have a pile of small chips (randomly distributed) and a bunch of ants on a flat surface. The ants run around randomly. If an ant runs into a chip and is not carrying anything, it will pick up that chip and then continue to move about randomly. If an ant, on the other hand, is already carrying a chip and runs into another chip, it will drop the chip it is carrying and then continue to move about randomly. What does the surface look like after a long period of time? That is, how are the chips distributed?<br>

Sorry to necro such an old thread, but I came across it when browsing the archives and I wanted to recommend Foggy Brume's <a href="http://www.pandamagazine.com/">P&A Magazine</a>. The puzzles are fantastic. He also created a free really cool online puzzle extravaganza called <a href="http://www.pandamagazine.com/island/index.html">The Puzzle Boat</a>.comment:ask.metafilter.com,2008:site.94764-1436217Fri, 08 Aug 2008 03:17:33 -0800painqualeBy: grobstein

Here's a couple: <br>
<br>
A perfect number is a positive integer which is the sum of its positive divisors. For example, 14 + 7 + 4 + 2 + 1 = 28, so 28 is a perfect number. Can you find an odd perfect number? If not, why not?<br>
<br>
Show that every even integer greater than 2 can be written as the sum of two primes.<br>
