Every league has its own code. Scan it where it's displayed and you go straight in; arrive from this site and you'll be asked to type it. Either way you land in that league and nobody else's.
Every fixture, one scoreline each. The whole round closes a day before the first kick-off, so nobody gets to watch Tuesday's game before picking Wednesday's.
If your league is run somewhere with a screen, checking in for the match being shown doubles your points for it. You still have to be right — turning up multiplies a good call, it doesn't replace one.
Plus three season-long calls — the winner, the top scorer and the best keeper — worth up to 35 more. Knockouts are scored on the 90-minute result: level after 90 is a draw, whoever goes through on penalties.
No leagues are listed publicly just yet.
A league of your own with its own code, whether that's a pub, a five-a-side team, an office or twelve mates who argue about football. Somewhere with a screen gets the double-points check-in as well, which is a decent reason to watch together.
