9×9 Sections Puzzles

The 9×9 is one of the rarer sizes here. Only 46 of the 582 puzzles in the Archive use it, and it is the largest grid Sections publishes. About 45% of the players who start one finish it, taking 21:45 on average. The hardest one so far is March 24, 2026: only 22% of the players who opened it made it to the end.

Grid size sets the ceiling, not the difficulty. How the bars fall matters more, which is why the hardest puzzles list ranks on results rather than dimensions.
