A conversation about mathematics inspired by a Noughts and Crosses (Tic Tac Toe) board, covering Noughts and Crosses, a surprising number of variants, with a bit of higher dimensions and topology for good measure. Presented by Katie Steckles and Peter Rowlett.

Fun! Thanks for the shoutout @stecks and @peterrowlett. My rules for 4D noughts and crosses are here, if anyone wants a look. :) https://t.co/ryATOQOZiK pic.twitter.com/XANkyz9W5N
