In 2013, at a picnic, I stumbled across a strange variation of tic-tac-toe. Ever since then, I've been collecting mathematical games. We'll explore a few examples from my book Math Games with Bad Drawings, from a press-your-luck dice game to a numerical trivia game -- and we'll see what each game reveals about the interwoven powers of reason and imagination. All are welcome!!
