It's the most magical time of the year. When Europe unites in a carnival of glorious, camp costumes, glitter and pop music.
And the best part of it, it's an excuse for a knees up.
Now, we here at WalesOnline urge people to drink responsibly. Stop when you've had enough. But also, cancel your plans for Sunday.
We've split our drinking game into two sections: The main show and the results.
Do one, do both, don't do any, the choice is yours. Just don't hold us responsible.
The rules:
The grand finale will air on BBC One on Saturday, May 22 with Graham Norton hosting as usual, you can get live updates here.
It will be broadcast live from 8pm until 11:45pm on the channel. Fans will also be able to catch up on the Eurovision Song Contest on iPlayer if they miss it.
It will also be broadcast on BBC Radio 2 in a programme hosted by Ken Bruce.
The competition will also be live streamed on the official Eurovision Song Contest's YouTube channel.
