Leaderboard

Overall: every ranked case earns points by difficulty (Easy 1, Medium 2, Hard 4). On equal points, the lowest total ranked time comes first.

By case: Only your first solve of each case counts: replaying never changes your place. Each hint level you open (level 1, then level 2) adds 30 seconds to your ranked time. A first game where a hint revealed a cell (level 3) is not ranked. Times are checked: an implausible result is not ranked, and a faked one may be removed.
