    The 100 game was created by the Reverend Charles Lutwidge Dodgson -- who you may know for writing Alice In Wonderland under the pen name Lewis Carroll.
    Carroll’s Oxford students were amazed. On February 5, 1856 he wrote in his diary: “... the trick of counting alternately up to 100, neither putting on more than 10 to the last number named, astonished them not a little.”

    Or u could let them go first and keep picking a number to get to 9
    For example:
    Total:9 then his/her say a number again then keep going till 89 then when they pick a number between 1-10 then say the number to get 100 to win

    I found a pattern in the sequence
    1 12 23 34 45 56 67 78 89
    The last digit of the number will be the first digit of the next number and the second digit of that number will be the first digit+1

    I got a game where you had to get "15", and your move had to be from 1-3. It took me a few games, but I figured out the trick and became unstoppable (at least when I began).

    When you were "playing with yourself" I saw what you were doing right at 89. I was like. "well that's 11 off of 100, you can only pick up to ten so no matter what your screwed. Then I thought. How did he get to 89 though? Because out of all possibilities its just one off of 10? Yeah right. So if you were to reduce your number by choice of theirs (11 to whatever) then you can win no matter what by default.

    I play a game called bonk. Whoever gets the number 10 loses. My theory is whoever says 1 first wins. If I say one, you could either say 2,3, or 4. Then I would say 5. Then you could either say 6,7, or 8. Then I would say 9, and you would lose because you would have to say 10.

      This was covered in the video: simply play a number that lands you back onto the 11n+1 sequence (1, 12, 23, 34, 45, 56, 67, 78, 89, 100)
      For example, if your friend starts on a 7 you would play a 4, landing you on 12 where you just play as usual. (friend plays 8, you play 3. Friends plays 2, you play 9 etc until you are on 89 where you are guaranteed to win as long as you continue with the 11- whatever your friend plays)
      Example game:
      You (total) | Friend (total)
      x (0) | 4 (4)
      8 (12) | 5 (17)
      6 (23) | 8 (31)
      3 (34) | 3 (37)
      8 (45) | 2 (47)
      9 (56) | 4 (60)
      7 (67) | 5 (72)
      6 (78) | 4 (82)
      7 (89) | 9 (98)
      2 (100) And you win!
      The only way you can lose is if your friend knows the strategy and they start first in which case, you are dead.
