This weekend sees the first exciting finale to the 6 nations since 2015. The last time the Six Nations title was still undecided going into the final week was “Super Saturday” way back then.

But with such an exciting close to the tournament comes a headache that many less than fanatical rugby fans (like me) are having.

How do you figure out who wins the Six Nations?

All the different combinations of winners and losers, as well as bonus points and differentials, makes for a very complicated final weekend. If Wales win it's simple, they’ve secured their 12th Grand Slam, their first since 2012 and will take home the Six Nations title for this year.

But if Wales lose it's a very complicated kettle of fish indeed. England or Ireland could win, and Wales are still in with a shout as well. Who wins is a total mystery to people like me.

It's very complicated but will be really useful information. It's also relatively easy to figure out if you have an expert to help you.

One industrious and expert Reddit user has put together the flowchart below to explain what could happen this weekend. It’s simple and easy to follow - even for a relatively fairweather footy fan like me.

This is exactly what Passle is doing with the various experts and clients we work with. To those that fully understand a niche, demystifying one element of it is easy, helpful and sets you up as the expert and the obvious choice for information (and possibly services in the future).
