Twitch Solves IMO Shortlist

In early 2020 I created a Twitch stream that I stream on some (but not all) weeks. The series is informally titled Twitch Solves IMO Shortlist.

Content includes:

  • Working on IMO shortlist or other contest problems with other viewers.
  • Twitch chat asking questions about various things
  • Games: metal league StarCraft, AoPS FTW!, Baba Is You, etc. I have a preference for somewhat difficult puzzle games.

I also upload past broadcasts to YouTube.

Twitch schedule

You can find a schedule for the stream, also below. Friday night at 8pm Eastern is the usual time.

Streaming software

Software used on the stream includes:
