The biggest prize in world rugby is finally upon us. And to make sure you enjoy every single minute of the action from Japan this year, we're thrilled to be bringing back the Guinness Pint Predictor.

What's more, we've been grafting hard on the training pitch to ensure there are a couple of snazzy new features thrown in. Back your rugby knowledge? Time to prove it and win more than just bragging rights in the process.

Let Flats and Shanks explain how to play and what you can win.

Call It

For every international match throughout this Autumn's tournament, there is a free pint of Guinness up for grabs. Simply call the winner of each game and choose by how many points.

Challenge

You can set your predictions anytime and anywhere before kick-off. Crucially, you can make sure it means more by challenging your mates in a private league or by taking on the Guinness Legends League.

Win

If your prediction is correct within 3 points you’ll win a free Guinness to redeem immediately.

Getting your prediction bang on will earn you bonus points, and whoever is top of the overall league after each round of fixtures will win a pair of tickets to the Guinness Six Nations in February next year.

Gift

New feature, ahoy! You asked and we have provided. If your prediction is correct within 7 points, you'll win a 'Giftable Guinness'. This is a pint that you can send to someone deserving of one. Simply share your code with them, or send it via the app. Absolutely legendary behaviour. 

T&Cs apply, over 18s only. See app for the full list of participating venues.
