How do the weekly leagues work?

Each week you play in a league with learners at your stage: levels 1 to 4, 5 to 9, 10 to 19, or 20 and up, set by your level at your first game of the week.

You score a point for every item right on the first try without a hint, in any game except practice; accuracy breaks ties. The week ends on Monday at 00:00 UTC, and everyone who played gets a notice with their place.
