I finally went and read the basic rules of team handball. The ball-in-net-to-score part was clear, but the more nuanced parts were not. Turns out it's super straightforward and seems less full contact-oriented than even basketball or soccer. I'm surprised it's not more popular here, especially recreationally. I could see people of a lot of different ages playing this, and you'd just need a regular gym-sized area. Key Points (from http://usadth.tripod.com/rules.html): - 3 steps before and after dribbling (with unlimited dribbling once you start, but no double dribble) - Can't pull/hit/punch the ball out of an opponent's hand - Can't dive on the floor for a loose ball - Can only use torso to physically obstruct another player - Big area (6m line) around the goal, you can leap into it but you must release before you land
