Regifting Robin

[baregreg]

Not sure how this works. But it gives the right answer.

Hey! I tried this 3 times, using 3 different number pairs, and each time was right. How does this work? What's the magic?

By the way... has anyone noticed before Labor Day all the Halloween & Christmas stuff selling on store shelves? Businesses seem to be gearing up for sales sooner every year. Hate to say it, but only 102 shopping days left 'til Christmas!

[gmoney]

only got it right 2 of 4 times with me. the 1st 2 times...

[Kouak]

I'll let you know the secret in a week. Enjoy the puzzle in the meantime.

[Kouak]

only got it right 2 of 4 times with me. the 1st 2 times...

It always works. Redo the math. 00 to 09 do not count since these "2 digit" numbers are really single digit numbers.

I did it with 52 and 50. it got it wrong.

[Lord Drakkus]

It does always work. It's also a very simple trick.. I'm with Kouak, one of us will tell the trick in a week.

[missouriboy]

I did it three times, and figured out how it worked.

The method is NOT mathematical. :sneaky:

[MeBNude]

O.K., that's just a little creepy. :eek: And I didn't figure out how it works so I shall sit here waiting for the promised explanation next week.

[nimrod]

Well it does not always work, I do not know what the trick is, but only got two of the four times I tried it.

[MeBNude]

All I know is that when I randomly picked a number without doing the math, Robin was 100 wrong. But when I did the math as instructed. She was right... 6 out of 6.

I like clever tricks!

You know what?? It does work!!!shocked
I tried it 3 separate times (with 36, 42 and 52)...and all 3 times it got it right!!!:surprised: Now, how it's done I don't know. What's the answer??:confused:

[JoseO42]

The end result seems to be a variant of the number 9. I wonder if that is why it is working.

In other words, whatever number you choose, once it is subtracted according to the rules, will be divisible by the number 9 in whole numbers.

It was a pattern that I noticed and might be why the trick works.

[baregreg]

Well I think I know how it works (somewhat).
The "power of nine" is involved, right?
Number Nine - Number Nine and etc... (Beatles' White Album) :)

Here's another version of the same thing.

We posted at about the same time, so I didn't see you had the same idea.

Such as:
10 - 19 = 9
20 - 29 = 18
30 - 39 = 27

and etc.

[Kouak]

Yes, the math will always result in a number that is a multiple of 9: 9, 18, 27, 36, etc. If you notice the answer grid for each of these numbers, it has the same gift! They are the only numbers that have the same value. All of the other numbers have different gifts.

The other trick is the size of the table. No multiple of 9 is close to another or else you might have noticed the duplicate gifts.

Aren't tricks great? The first couple of times I did it, I was really surprised with the answers. Thanks for the fun puzzle.

[maliakei]

Me too! I don't get it, so we'll just have to wait for the secret to be revealed.

[missouriboy]

C'mon folks! This joke requires using your thinker a lil bit. Here's some hints:

1. The site claims to "read your mind". It would have to, because you never really tell it what number you picked. (Or DO you?) :surprised:

2. When you bought your computer, did you pay the extra charge for the optional "mind reader" peripheral device? :confused:

3. If you didn't, then the site CANNOT read your mind. :rolleyes:

4. So ask yourself, "How DO I communicate to the website?" :confused:

5. Refer back to #1. :sneaky:

[missouriboy]

Well it does not always work...You are correct! But it sometimes succeeds in making people THINK it always works.

You are correct! But it sometimes succeeds in making people THINK it always works.

It always works. See the above solution. The math has you take the selected 2 digit number and subtract the first digit and then subtract the second digit. Some examples are:

10 - 1 = 9 - 0 = 9
11 - 1 = 10 - 1 = 9
12 - 1 = 11 - 2 = 9
13 - 1 = 12 - 3 = 9
14 - 1 = 13 - 4 = 9
15 - 1 = 14 - 5 = 9
16 - 1 = 15 - 6 = 9
17 - 1 = 16 - 7 = 9
18 - 1 = 17 - 8 = 9
19 - 1 = 18 - 9 = 9
20 - 2 = 18 - 0 = 18
21 - 2 = 19 - 1 = 18
22 - 2 = 20 - 2 = 18
23 - 2 = 21 - 3 = 18
24 - 2 = 22 - 4 = 18
25 - 2 = 23 - 5 = 18

Try it again and pick the number 10 to get 9. Look at the gift chart and see that the "9" gift is the same for 18 too. This means that any number you pick from 10 to 25 will result in the same gift.

It always works. See the above solution. The math has you take the selected 2 digit number and subtract the first digit and then subtract the second digit.

It does not always work, like I said it only worked two out of four times for me, the math does not matter at all. The likelyhood of it being correct is very high, but it is not always right. Pick the same number each time and it will be wrong.

[yellowstud]

How does it work? Please tell me :surprised:

[Kouak]

It does not always work, like I said it only worked two out of four times for me, the math does not matter at all. The likelyhood of it being correct is very high, but it is not always right. Pick the same number each time and it will be wrong.

It always works if you follow the directions. Say, as in their example, you pick the number 25. You then subtract the first digit, a 2, and get 23, then you subtract the second digit (from the original number), a 5, and get 18. Now when you look on the gift chart at number 18. You do not use your original number 25 but rather your calculated number (25 - 2 - 5) of 18. Robin will pick your gift.

Do it again with 25 and look at number 18 on the gift chart...remember you must use your calculated number not your original number. Robin will again guess your gift.

Try it a third time using number 25. You calculated number is still 18. Look at the gift for number 18. While you are there, look at the gift for number 9 and number 27. They are the same gift as for number 18, right? As you can see, the first 3 multiples of 9 (9, 18, 27) are the same gift. In fact, all of the multiples of 9 have the same gift.

If it does not work for you, please tell us what you did on each page and the numbers you start with and calculate. Usually a "wrong" answer is because we make a mistake in the calculation or we look up the gift using the original number.

Good luck.

[missouriboy]

Kouak, you are having trouble seeing past the wall you have erected around your number theory. :(

Please go back and review my Post #18, and concentrate on Hint Numbers 2 and 3.

Got it? Good! Now let's explore your thesis further, and see where it leads us...

EVERY 2-digit number, when operated upon per the instructions, yields a multiple of 9 for the result. THEREFORE, EVERY "correct" answer would have to be the same gift, the Fuzzy Scarf, which IS listed for EVERY multiple of 9 in the grid.

Now, does the site ever give an answer that is NOT a Fuzzy Scarf? YES!

Then how can that be right? We've established that the ONLY correct answer is Fuzzy Scarf. So, if any other answer is ever returned, the website logic itself is flawed.

Go back to what I said in Hints 2 and 3... the fact is that the website, and the computer programming behind it, can NOT read your mind. Right?

Therefore, it matters not two whoops whether you do the math correctly IN YOUR MIND, because the computer has NO idea whether you DID so or NOT, or whether you even did it AT ALL, or whether you were thinking about another subject entirely, such as your girlfriend's goldfish, or your favorite brand of microwave popcorn. THE MATH DOES NOT MATTER!!! IT HAS ABSOLUTELY ZERO EFFECT on the outcome. TRY IT AND SEE!!

So, then, what DOES cause the computer to select various answers for you? (Even though "various" answers are wrong, since we've established that only ONE answer is correct, according to the instructions.) Go back to Hint Numbers 4 and 5 to continue your pursuit, but you have to get past the idea that it's mathematical. ;)

[nimrod]

Good luck.

I have already told you what I did, I picked the same number multible times, and still followed the directions. I got two wrong answers. If it always worked I would not have seen any wrong answers, since I did see wrong answers it does not always work.

[baregreg]

Gosh guys, this was suppose to just be a fun thing to do/checkout. :surprised:

[Lord Drakkus]

Okay, we've determined that the answer is always a multiple of nine, correct? Okay then.

Next time you guys try this out, look at all the nines. The answer is not always the same each time, it changes. One time, the nines will be the fuzzy scarf, another time it will be something else. The point is this; whatever the nines are, that's going to be the answer.

The math is actually quite important, since it sets you up with a multiple of nine. After that then all the site has to do is tell you what the answers are, and VIOLA, mind reading website. Even though it actually tells you what to think every time.

Now, explain this one. (The datingwar site, I mean.) I did this with 52, 62 and 72--meaning 52-5=47-2=45, 62-6=56-2=54, 72-7=65-2=63.
All 3 times, it guessed right.:eek: Now where's the trick with that??:confused:
Something's screwy somewhere...:sneaky: I mean, it all works on variables of 9 and all, but this is ridiculous.

This will be my last post on this thread.

I think Lord Drakkus answered missouriboy's concerns well. Let me underscore the key point. The gift is not the same each time however it will always be at a multiple of the number 9.

I have already told you what I did, I picked the same number multible times, and still followed the directions. I got two wrong answers. If it always worked I would not have seen any wrong answers, since I did see wrong answers it does not always work.

When I asked that you tell us what you did, I meant you tell us the number you picked and what you did for the math and the results you got. For example, you pick 72. You subtract 7 and get 65 and subtract 2 and get 63. You go to the grid and see that the gift is a Snow Globe. You click next and Robin picks Snow Globes.

If you want, pick the number 25 each time. They do the math for you to get 18. Go to the grid and see what gift is at 18. Robin will pick it. Next time pick 25 and get 18 after doing the math. Go to the grid and see what gift is at 18. Robin will pick it.

Now, explain this one. (The datingwar site, I mean.) I did this with 52, 62 and 72--meaning 52-5=47-2=45, 62-6=56-2=54, 72-7=65-2=63.

This works identically to Regifting Robin.

[missouriboy]

I think Lord Drakkus answered missouriboy's concerns well. Let me underscore the key point. The gift is not the same each time however it will always be at a multiple of the number 9.YES he certainly did. I was not aware that the answers changed every time. So, MEA CULPA! :o

Except that I still say the math does NOT matter, and the silly thing does NOT read anyone's mind. :rolleyes:

All ya gotta do is look at the gift for #9 and that's the answer. Period. No math exercise by the user is useful, required, or effective. Except to DISTRACT the victim. :D

I had not looked at it very many times, thus never noticed the answers changing, and I originally thought that the computer sensed where you let YOUR MOUSE POINTER LINGER ON THE GRID while you memorized the answer (this IS within the capability of the system). And I believe using THAT approach could be developed, using a different type of question, and would mystify the user even more effectively.

I am a man that can admit when he wrong, you are correct it should be right every time. If I did something wrong I do not know what it could have been, I could have looked at the wrong number, which is hard for me to believe after picking the same number each time, or I could have assumed that the prize was the same each time and it just happened to have the same prize twice for the spots, which is likely but I thought I looked at the gift each time. I fully understan how it works and if you follow the directions it will pick the correct gift each time.

You may have done what I did a few times when testing it...I was thinking of the original number so much that I looked at the gift for that number, not the computed number.

It has been a while since I tried a puzzle like this. It always freaks me out the first few times when the web site can "read my mind!"

Have a great day and weekend.
