    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.”

      I figured this out independently before I watched this. Instead, I used the number 21, since people in my school play with 21. I always win, and they get really mad.

      question, What if you are going 2nd in the Number game, do you still have to do the 11 - opponent number?

    So in other terms what ever number they chose just add another number to make it go up to 11 like so... 7+4=11 5+6=11...

    I saw this video last night and I studied the number game to win in every situation except the one that your opponent starts with 1 and knows the series. When I went to school I challenged my math teacher to play this game to end a bet we had. It turns out he figured out the pattern already while I was explaining the game to him. I lost but I also won every other match I had with the teachers and my friends leaving them confused on how I won every single time. I also figured out the mathmetical explanation it's a pattern which is 11n+1 (you get rid of the 1 first and then add 11 in total each time to reach 89 which is n=8 11x8+1=88+1=89)
    Well thank you for reading this long ass comment and don't forget to like the video and support this awesome channel 👍

    My mom used to make me play this with her when I was really young and she’d always win and I didn’t get it until I finally figured it out and then I always wanted to go first to win. And then she changed the game. And then I just stopped playing it with her.

  • Henry Cheeseburger
    Henry Cheeseburger 14 days ago

    A game that I used to play was called 21 it was the person who said 21 looses, to play you need to count up with either 1,2 or 3 and how you won was by going second and making it so you numbers are in the 4 times tables and near the end when you friend thinks that they have won you say 20 and force them to say 21 so you win!!!!!!
    Now go think about why you just read this it’s not like you are going to play the game but at least you know how to win

    • wolfuu
