Every Monday (UTC) you are placed in a group of about 30 people with a similar pace and time zone.
Earn XP all week. The top 10 with XP move up a tier. Earning XP never moves you down. If you take a couple of weeks off you restart one tier lower and can climb back any time; never below Pawn, and your streak and progress are not affected.
You show up as a generated name like “Brave Knight 42”. Nobody sees your email, your real name or any global ranking, and only the people in your group see your name and XP.
It is optional, and you can leave any time. Leaving deletes your league data.
0 XP
Your score is being checked, so you are hidden from the board for now. If everything is fine it comes back on its own.
