Imagine this. You are on a big stage, looking at the 1000 listeners and you have exactly 2 minutes to start, explain and play a game.

What can you do in so short time? You rely on what people know already. Everybody knows tic-tac-toe.

Great starter for other games or fast energizer when you literally have seconds to spare.
