It’s not predictable, it’s just impossible to end in the spots taken out.

Of course you can "predict" how someone will very likely behave in a given controlled scenario when you act as an omniscient observer who arbitrarily dictates the options available and not to participants in the given scenario -- you're essentially having the participants play-out a game with which you've pre-scripted its conclusion, leaving the participants little chance to beat the house like in gambling.

Explanation 101; 1= Possible squares to go to 2= Impossible squares to go to X= Removed Square Notation is horizontal instead of in a square; write it out if you don't get it. 212 122 222 X21 212 121 X12 12X 212 X2X 21X 12X XXX X2X 21X XXX XXX 12X If he didn't take squares away noticed the checkerboard pattern? 212122222 121212121 212121212 121212121 212121212 This is due to moving uneven numbers so you cant stay on a square he wants to remove!

move right then go in a loop right, down, left, up, rinse and repeat. you'll end up on the top- right. (oh, and move right on the first turn)

This is flawed, you gave me the choice to move up, down, left or right, I moved left on your face. You didn't say in the rules I must stay on a sticky note :P

1:59 when I moved for "2" I moved to the face with tongue out, and it moved, I thought I had touched it!

It don't work though
Brandur Arnoarson (1 год назад)
Spencer Clifford when you reached an edge, did you loop around, or did you change direction? You are not allowed to loop around, if you do, it doesn't work

As Vale i did play correctly lol

Spencer Clifford watch the end of the video - how should it be possible if you understood the rules and played correct?
Spencer Clifford (1 год назад)
As Vale i didn't, actually a lot of people said that it didn't

Spencer Clifford you did something wrong...

i landed on the wavy lines cause i though they were my fav square so i stayed moving away and back to it, that may be cheating?
David Davison (1 год назад)
And the only rule the guy didn't make clear is that you cannot use a wrap function. If you can use a wrap function, then you can go left from the left-most side and such. Without this clarified, you can violate the rule by believing in a wrap function.

"Move 1"*remove all 4 corners* "Move 1. You're now on the middle square!" A bit simplistic, but that's what you're doing here.

+Orlando Armijo You did it wrong.
Sinom (2 года назад)
yes it is really obvious why it works but why are there still people saying they "won" yust cause they can't followe directions
Howler Grace (2 года назад)
it worked!!!
Doruk Efe Gökmen (2 года назад)
Start and go up and down all the time...
Doruk Efe Gökmen (2 года назад)
+lol lol I was in fact trying to provide a proof why this should work
Doruk Efe Gökmen (2 года назад)
+shootingblueyes True, that was basically too implicit of a comment. But it was basically aimed to help people to see why this works.
shootingblueyes (2 года назад)
+Doruk Efe Gökmen My apologies, but nearly every other comment has been trying to dispute the proof, so it was a fair assumption to make, based on your brief statement, that you were alluding to it not working if you 'Went up and down'
Ebo Abo (2 года назад)
+Doruk Efe Gökmen If your point isn't to try and prove it doesn't work then I have no idea what your point is dude
Doruk Efe Gökmen (2 года назад)
+shootingblueyes I really do not understand what you mean by working, and it is funny how you interpret my comment as an attempt to prove this trick wrong. If you try to move back and forth it will be easier to see that for odd number of moves, it is impossible to end up in squares that are even places away from the initial point, you just cant get an even number by subtracting an even number from an odd number lol :D

Every game, choice or anything at all has one outcome. There is no true chaos.
vleesevlons (1 год назад)
+TheFinalAzcent there are no objectives, only rules. The rules are only set so that he can predict. What's the point of playing the game if there's only one outcome?
Azcnet (1 год назад)
what's the point of cheating, if cheating makes you fail the puzzle?
vleesevlons (1 год назад)
Nekogami-Crystal i cheated. Rules are meant to create order out of chaos. But without chaos there would be no rules, so i had to cheat.
Did not work for me
It was it was wrong

He did not specify that I could not move into the blank spaces on the screen, so I did. One blank space of a 3x3 grid at a time, and I broke his test. I win!
