December 31st, 2021 update

I won't be posting any more problems today until 11:59 PM EST. 

At 11:59 PM, I will post a very unique problem that is suitable for this day. 

Take a wild guess for what it could be 😉


  1. hmmmmm i wonder what it is
    a problem about snow or new year?

    will it be a super troll problem from 2021 contest season? (like 2021 spring amc10b p2)

  3. And not only will there be a problem, but there will also be a meme.

    *everyone looks up*

    I already know what it is...

    I'm not going to spoil it, but I'll just let you know that it will be a HARD problem. In fact, it will be VERY, VERY, VERY HARD.
