The Origins game convention is held each June/July in Columbus, Ohio. It's one of the larger game conventions in the Eastern USA, with more than ten thousand people typically in attendance.

Since the year 2000, Origins has also been the home of the Looney Labs Big Experiment series of game events, that hosts some of the tournaments that could be considered the world championships of Looney Labs gaming, including the International Icehouse Tournament.
