- What it is
- Everyone plays the same map, and can retry it as often as they like. A new map and a fresh board come out every Tuesday at 00:00 UTC.
- Who's on it
- Every finished attempt gets its own row, so a player can appear more than once.
- How it ranks
- Problems solved, then attempt number (earlier first: later attempts have seen more of the map), then wrong submissions, then time from start to last solve.
