Has Anyone Played These Frisbee Variation Games? Share Your Experiences!

I've been brainstorming some fun variations to traditional ultimate and I'm curious to know if anyone here has tried playing any of them. If you have, I'd love to hear about your experiences, feedback, or even suggestions for tweaks. And of course, if you've got your own frisbee game variations, do share!

King of the Hill: Essentially a "winner stays" setup. The team that scores becomes the defenders for the next round. Games are typically 1 point.

All-Hands Hustle: Before a point can be scored, every member of the team must receive the frisbee at least once.

Twin Disc Duel: Two frisbees in play! Points can be scored if either disc makes it to the goal, or only if both make it in. There's also an element of risk: if a disc is dropped, it can either result in a turnover for both or just the one that was dropped.

Secret Agent: A fun twist on deception! One person on each team is designated as a secret agent, whose goal is to subtly sabotage their own team and aid the opponents. Each team is aware of their own spy, but the trick is not letting the other team figure it out!

Pivot Promenade: When a player stops and catches the frisbee, they're allowed two steps and then they must pivot. Walking into the end zone with the frisbee is prohibited.

Looking forward to hearing from you all! Cheers.
