Take this simple test if you don’t believe it…

Get out of my head!
My finger was on the Ø when it was removed D: I must be special :D
So was I! I predict I’m unpredictable :)
Not sure you did it right then…. it’s not really about being predictable, its all about math. Every step the squares you could be at access. After the first step its all about even or odd numbers. After you move seven times [odd] you will be on either 1,5,7, 9 (if you number them like a phone keypad). After moving 3 [odd] times from one of those spaces, you will be on either 2,6, or 8. After another 7[odd] times, you’ll be on either 5, 7 or 9.
The reason even/odd matters is this. There are really only two sets of spaces, the ones at 1 3 5 7 9 and 2 4 6 8, although he removes 3 at the beginning, so you’re left with 1 5 7 9 and 2 4 6 8. When you start the game, you’re at either 2 or 4. Moving an even number of times from one of these sets keeps you in the same set. Try it, move two times from space number 2, and you’ll be either on 2 4 or 6. If you move an odd number of times you end up in the opposite set.
So, when you start in the odd set, move an odd number of times, you end up in the even set, (so he can safely remove an odd number). Then you move an odd number of times end up in the odd set and he removes and even numbered space.
Basically he keeps taking a number out of the opposite set until you’re left with only one choice.
[1 5 7 9] [2 4 6 8]
[1 5 7 9] [2 6 8]
[ 5 7 9] [2 6 8]
[ 5 7 9] [ 6 8]
[ 5 9] [ 6 8]
[ 5 9] [ 8]
[ 9] [ 8]
[ 9] [ ]
And at the end, you have to be on space 9
**Every step the squares that you could be at change**
I knew there’d be a mathematical explanation for it, I just would never have worked it out! Thanks for ‘splainin’!
Thanks for the explanation! :)
Me too.. :p
Call me unpredictable.
this is not a prediction, it’s logic. notice that he only counts to odd numbers.
He could do even numbers and it would still work out, he’d just have to remove different tabs.
I kept trying to get to the ones I knew he’d say I wouldn’t choose (and I was right about each one) but I couldn’t get there. Leaving me to realize — hey, this is a math game and I can’t win! ;)
He was wrong for the last two rounds. But then, I was trying to be ornery.
each time he said I predict you didn’t choose? that was my choice except for one. it’s not math it’s manipulation how many of you would simply go back and forth on connecting squares? predictability counts on the fact that the majority of you would not do it.
It’s math. You did it wrong. See above explanation.
I just went back and forth on connecting squares and he was still correct in his predictions. Which means that both of us are predictable and neither of us is special. Get over it.
Anyone that says they’re not predictable just don’t know how to follow instructions. Be proud of yourselves…
I ended up on 4 different squares that he said “won’t be”. I checked and I obeyed the rules…. odd.
