This week’s championship
Daily difficulty changes, so weekly competition uses placement points rather than adding raw solve times. #1 earns 100 points, #2 earns 99, and every ranked finish earns at least 1 point.

Stronger validation
Server clock + game clock
Ranked attempts are server-timed and the submitted game timer must closely match. Superseded sessions and suspicious timing mismatches are rejected from the ranking while local play remains unaffected.
