Firstly, thanks for the post. This "ask" site is going to become a great resource worldwide to understanding (and hopefully conforming) kubb rules internationally. Thanks for the post. In current US Nationals rules, the above scenario (I believe) would be ruled in bounds. "A Kubb that can be raised in bounds must be raised in bounds". There is no discretion between a flat kubb on the line or in front of the line. US Nationals rules are looking at the potential footprint of the kubb. If the footprint is 50% on the line (or too close to call out) then it is in. It appears the World Championship rules work differently, and the kubb has to at least "touch" the line. Which I find weird for one reason: this is the only line rule in kubb that relies on a "determining edge". Kubb is the only sport (I know of) that doesn't use a determing edge for all facets of lines. In hockey the determing edge of the goal-line if the far side of the line (the puck has to cross the line entirely. In American football, the determing edge of the goal-line is the nearest edge (the tip of the ball has to touch the line). Kubb (aside from the WC rule above) doesn't use determining edge, and sometimes that leads to judgement calls by officials (in/out), even if lines are painted. I personally don't like that as much. Imagine bringing in the line 3.5 cm and saying if it touches a line its in. No more judgement calls. No more ambiguity. This however leads to potential problems with the centerline though. Okay, I'm digressing a bit, but my opinion is that it is easier to call in/out on a standing kubb than it would calling a flat kubb touching an imaginary line. I also think you should either play half-in/half-out OR play determining edge. Pick one, but don't use determining edge in some situations, then half-in/half-out in others. Again, that is my 2cents, and I have seen the overall "theme" of the US National rules drift closer and closer to World Championship rules. I personally think some rules in US Nationals work better than Worlds, and that happens. Consider "no-touch icing" in hockey. Small AAA Leagues use that rule (NHL doesn't), and the overall feedback from fans is "we like that better". Its safe, it speeds up the game, and it makes sense. Well, the NHL watches them, gets feedback, tries it out, and I would expect sometime soon you will see NHL adopting that rule. For this rule, I think for now based on what I know, I like the US National rules better. I would encourage US Nationals to try the WC rule out, and for other tournaments using this rule to try US Nationals way. Use this forum for sharing the gaps, successes/failures with the rule, and continue to work on unified rules. We will never have the Kubb Bible that all countries use that is the same. But we can at least understand the differences, understand WHY there are differences, and in some cases agree to disagree. In other cases, changes could potentially be made either way. I am just happy to find people out there that are as passionate about kubb as I am. Thanks Tony!
