Human Curling was invented and produced by an organization called Obscure Games. Clearly that is not enough information. Hence, I quote from the article in the Pittsburgh City Paper (which I strongly urge you to read, because it’s fun and funny):
Here are the basic rules of Human Curling: You prop yourself in a wheeled office chair. You can kneel or sit, but once you’ve settled on a position, you have to stay there. Then you propel yourself forward, either by pushing yourself off a wall or with a running start. Or — why not? — a teammate can push you.
What else? Oh, yes: When your chair rolls into place, you dismount and stand still on your spot. When the opposing team rolls forward, you can tag moving players (disqualifying them), or you can shove your teammates onward.
And it’s all played on a basketball court.
This manifestly pointless game clearly tweaks the heart of silliness, carrying with it a vibe reminiscent of the herein-much-lauded Circle Rules Football, which is self-explanatory, insofar as both games were invented by the same people.
Fear not, people of play, we are in good hands.
