I perform Martin Gardner’s “Tic-Tac-Toe Force”
This is a simple, classic routine that manages to pack a punch when pulled off well. It’s also a very old routine, and the origin isn’t fully known. I attribute it to Gardner because when I learned the trick from one of Brian Brushwood’s videos, that’s who he said came up with it, but it’s possible someone else had the idea before.
I actually did this trick at an open mic last year, but didn’t post it then because it went badly. The participant I selected smoked some weed before the show, and I swear I am not making this up – she forgot how to play tic-tac-toe. Seriously. She was putting down X’s when I told her that was my symbol, trying to put two symbols in the same square. It was a mess. But that’s the risk you take sometimes.
