The game is designed to last 1 hour. You can make it longer (if desired) by including more surprise challenges or having a more in-depth discussion at the end.
Start planning your game and preparing your materials a few weeks beforehand. Most facilitators report spending 1-2 hours preparing the game materials. On game day, give yourself 15-30 minutes to set up the game room. Find more information on the Play the Game and Materials pages.
