The existence of officials looking for infractions in the few rules that they do have does not mean that overall they don’t have a looser set of rules compared to head to head competitive games. Like I said before, there often isn’t even a turn order for these events. You make your number of attempts over a long period of time and then are done.

I wouldn’t call those events “play” either. No one is really having fun riding a heavy stone multiple times. They might feel accomplished afterwards. But they aren’t engaging in play. And I still say it’s not a sport. You busting out a tautological oxford definition doesn’t really help anything.
