http://riddle.kaoskorruption.deltaanime.net This riddle is super hard but lots of fun. I think it's new. I've gotten to level 5. See how far you can get.

Below are the names of six plays. Five are by William Shakespeare and one by George Bernard Shaw. What are their names? (Measurements are in Imperial.) 1. 6" 2. 9" 3. 12" 4. Wet 5. Dry. 6. OO, OOO

In just FIVE minutes you should learn to quickly multiply up to 20x20 in your head. With this trick, you will be able to multiply any two numbers from 11 to 19 in your head quickly, without the use of a calculator. I will assume that you know your multiplication table reasonably well up to 10x10. Try this: Take 15 x 13 for an example. Always place the larger number of the two on top in your mind. Then draw the shape of Africa mentally so it covers the 15 and the 3 from the 13 below. Those covered numbers are all you need. First add 15 + 3 = 18 Add a zero behind it (multiply by 10) to get 180. Multiply the covered lower 3 x the single digit above i…

This 2x5 grid is filled with digits which are all different. the 4 digit number B is a multiple of the 4 digit number A. All but one of the 2 digit down numbers are primes. No 2-digit and 4-digit number starts with 0. In which square must 0 be placed? Explain why this is the only possible square. Complete the grid and explain at each step why you placed each digit in a particular position.

Open the Windows Calculator. enter 2 and press 'sqrt' to get the square root of 2 press '×' and then '=' to square the square root of 2 to get 2 again subtract 2 wha???

Follow the instructions: (if they seem vague to you just do what you think is right) 1. Read every direction before you start. 2. Take a sheet of paper. 3. Write your name in the top left corner of the paper. 4. Take scissors and cut a circle in the middle of the paper. 5. Write your name anywhere on the circle. 6. Scribble out your name on both the sheet of paper and the circle. 7. Write your favorite number on the back of the circle. 8. Multiply that number by two and write it below the first number you wrote. 9. Devide your new number by three and write the quotient below both other numbers. 10. If your newest number is between 1 and 100, draw a smile…

Hello! Heres a tricky one for all of you cryptography buffs. Please note, iv never tried to break this particular cypher-system before, so i have absolutely no idea how difficult it will be -- but im pretty sure that it wil be hard. If you want, i can encrypt some more stuff in the same way for you, to give you some more data to work with.

Ok, I have a question for all of you that a teacher asked me, and he told me it was an old cambridge interview question. I took a minute to think about it, but I was able to answer it correctly the first time. Ok, I drill a hole through the Earth directly from one side of the Earth to the other. I drill it in a staright line that passes through the centre of the Earth and the length of the hole is the diameter of the Earth(ignore things like a hot core of magma etc). Now I drop a ball bearing down the hole which experiences no friction or air resistance as it falls down the hole. Describe to me the motion of the ball bearing. It's sounding quite easy to me now:-)

Seeing as most of the threads here aren't all too entertaining, I don't feel so bad posting this one. I'm sure some of you have heard it before. It's more powerful than God, more evil than the devil, the poor have it, the rich need it, and if you eat it you die. WHAT IS IT?

Before I ask the question, I would like to warn you that this is a "think outside the box" type question. There is no mathmatical equation or anyhting like that to figure this out *hint hint*. It's just for fun. So here's the question: How can you fit nine cars into eight spaces?

Someone probably posted this already... but I couldn't find it...so http://www.notpron.com riddle website... the point is... getting to the higher level by ANY means necessary. most of my friends gave up before level 10 (there are more than a hundred levels).

Can anyone help me with the puzzle on this page? http://www.geocaching.com/seek/cache_details.aspx?guid=cd84de09-421f-41d9-9e0f-d934f524d113&log=y&decrypt= I've spent countless hours trying to work it out.

here`s a little puzzel for the math`s folk on here 3 Businessmen go into a hotel and ask for a room, they don`t have enough money for a room each so they decide to share a room. the guy at the desk was still new at his job and said it would cost 30 dollars (use pounds if you want). they each pay 10 dollars and hand him the 30 and goto their new room. sometime later... the manager asks the guy at the desk how`s bussines doin, he then explains about the 3 bussinessmen and the 30 dollars he got, the manager says NO, give them a discount if they share, charge them 25 dollars! the manager leaves along comes a bell boy. the guy at the desk hands him 5 1 one dol…

Okay, it's those puzzles where you look at a picture of words arranged in funky ways and decipher the hidden message: I'm sure everyone's done these, but in case someone hasn't, here is an example: Symphon That would be Unfinished Symphony. So, attached are the clues. Have fun.

if you have twenty diamonds on your bottom grill, and twenty mo' at the top, how many diamonds do you have total...

I think there was already a thread (not on the brain teaser and puzzle forum) that had this question so if you saw the answer, please do not post it. Thanks. Anyway, how is .999... equal to 1? It's actually simple, but a lot of people have a hard time figuring it out.

Just for something different... On The 4th of May, at two minutes and three seconds after 1:00 in the morning, the time and date will be 01:02:03 04/05/06. That won't ever happen again in our lifetime.Apparently it will be approx 400 generations before it happens again. . So can anyone come up with the next time and date or even past occurances that there is such a correlation?

Well, i thought that this thing might be kind of interesting and thought it didn't look that obvious in the photo. Sort of a brain teaser. Try guessing what it is? and give your explanantion. Anyone?
