How it works
- Every day at midnight UTC a new puzzle appears. Everyone gets the same one.
- Your result set is hashed in the browser and compared on the server, so any query that produces the right rows passes.
- Row order only matters when the puzzle says so. Column names matter.
- Puzzles range from 20 to 50 XP depending on difficulty. Signed-in solves count towards your streak and the leaderboard.
