Anchor-first beats random fitting
Start with pieces that define boundaries or symmetry. Anchors shrink the search space and reduce wasted rotations.
Rotation checks need a sequence
Try rotations in a fixed order instead of ad-hoc flipping. Structured checks make it easier to detect why a fit fails.
Order matters as much as placement
Correct pieces in the wrong order can still block the board. Sequence planning often decides difficult puzzles.
