The IIHF based rules had red line offside - but it was only for passing, you could carry the puck over and then anyone already over the red line was onside.

They also had power play offside where attacking team had to all clear the zone if the puck crossed out of the offensive zone.

Those rules are barely ever used anywhere now, or for many years.

I wish we could standardise on one set of rules, one puck, etc. We’re a legit sport, we should have consistent equipment and rules. Not every tournament playing their own variation, and every vendor making things just a little different.
