Guess the regift

REGIFTPick any 2 digit number and subtract both the first and second digit (of your 2 digit number) from the original number you selected.  Robin, the regift guesser, can guess what your regift is. 

Try it!  The explanation there is better than I gave you.

Thanks Hotz

  1. I don’t mean to spoil the fun but the way it’s done is every number you pick is a multiple of 9. If you pick any number from 11 to 99, the only possible answers you can get are 9,18,27,36,45,54,63,72, or 81. Look at those numbers on the chart. Notice anything?

  2. Not to undermine your theory, Jake. It’s quite plausible.

    However, I think it has something to do with where you put your mouse on the page. We automatically put our mouse over the box that is ours, without thinking. I tried it, by putting my mouse over a random square, and it worked.

  3. It has nothing to do with where you put your mouse or anything else for that matter. Jake is correct. It’s all mathematics. Only possible answers are multiples of nine and as Jake mentioned, all of those answers have the same answer.

    for example:
    11 = 11-1-1=9
    12 = 12-1-2=9
    13 = 13-1-3=9
    14 = 14-1-4=9

    You get the idea. It’s simple math.

  4. um no, 72= 72-7-2 = 63. Multiple of 9 and where you mouse was closest to just prior to clicking. Pick a multiple of 9 click a number near it. That’s your result.

  5. you guys all think too much, its all about your mouse positioning, you are moving the mouse to the number you are picking, thing never works or guesses right for me

  6. Vili, it’s cause you can’t do math apparently. No offense. Use a calculator.

    Now everyone, study the image carefully. Note how all the multiples of 9 have the same answer. It has nothing to do with mouse positioning, don’t believe me, try to trick it by clicking the complete wrong answer.

  7. Of course Jake is totally correct, but he omitted the fact that 10 is also a two digit number. Those that think it has anything to do with the mouse position are clearly displaying their ignorance.

  8. Hi…

    I think you all got it right, but you reminded me of something my grandpa used to say:

    “Don’t try to teach Math to chickens, you’ll waste your time and bother the chickens.”

  9. Those who are saying that it has to do with the math – your logic on the math part is right – but if you never put your mouse anywhere and just choose a random number on the board, in your head – say 13 – she’ll get it wrong. So the math part is correct – subtract and you will get a multiple of 9 – but that isn’t how she picks your gift.

  10. I don’t know about you, but when a web page starts talking to me, the only place my mouse goes is to the big red x at the top of the page.

  11. It’s both math and refresh.
    Multiples of nine, which is always the answer, show the same “gift”.
    Now every time you play the game the “gifts” change.
    Check the next time you play. The gifts change on the board, but the “gift” on the multiples of nine is constant.

  12. “just choose a random number on the board, in your head – say 13 – she’ll get it wrong.”

    But you’re not allowed to choose a random number in your head once you’ve seen the board.
    You have to choose beforehand. So if you choose 13, you HAVE to subtract 1 and 3, and you’ll get 9.

    You can’t just choose a random space on the board, it doesn’t work that way. Plus, it goes against the rules.
    You see, all the other spaces that are not a multiple of 9 are red herrings; they are there just to deceive you. You will never ever get any other number if you follow the rules.

  13. Math:

    y = tens digit
    x= ones digit

    (10y + x) is your number. If you subtract the two digits, you get: (10y + x) – y – x. That makes 9y. You will always get a multiple of nine. Fun stuff!

  14. The comments about this post are the best ever!!! To all the people who think it’s a “where I put my mouse issue”-Try not touching the mouse or putting it in the corner. WOW!!! I mean really people it’s always MATH!!!!! Thanks for the laugh though.

  15. Yeah i don’t know why people think it has to do with the mouse…you can have the mouse off of the page and it will still guess the multiple of nine that your number ends up being after the subtraction…it’s clearly the math and Jake is correct

  16. 10-1-0=9 11-1-1=9 12-1-2=9 13-1-3=9 14-1-4=9 15-1-5=9 16-1-6=9 17-1-7=9 18-1-8=9 19-1-9=9
    20-2-0=18 21-2-1=18 22-2-2=18 23-2-3=18 etc—>
    30-3-0=27 31-3-1=27 etc—>
    40-4-0=36 41-4-1=36 etc—>
    50-5-0=45 51-5-1=45 etc—>

    etc etc…

    Look at the chart and notice that 9, 18, 27, 36, 45, 54, 63, 72, 81, 90 are always the same as each other every time.

  17. Ok.. so here it is.. it’s called the rule of 9.. any 2 digit number between 10 and 99 equals a multiple of 9 (IE: 9, 18, 27, 36, 45.. etc.) So no matter what two digit number you choose, every time it will come out as a multiple of 9. If you look at the board and look at numbers 9, 18, 27.. etc, you’ll see that they all have the same Item. All they do to guess a diffrent item each time is change the board that you are looking at.. IE: all the multiples of 9 on the first board say ‘pen and pencil set’. you do the math correctly and it guesses pen and pencil set. Next time all the multiples of 9 say ‘bath salts’ and so on and so forth.. took me awhile to figure it out too.. haha

  18. I think it’s just another example of the redistribution of numbers from those that have more to those that have less…
