Acknowledgements and Changes
2024-06-06 Thanks to Rook for creating the rule panels for Crossroads, and for transcribing all puzzles so far!
2024-06-06 Thanks to PinkHoodie for sending a puzzle for the rollout; likewise to justkirb for continuing the trend of disguising genre within a genre.
2024-06-06 The link system was updated to better disambiguate similarly-named genres (cause: aliasing functions had been designed to ignore dashes, this was too imprecise). Thanks Rook and PinkHoodie.
2024-06-07 Adding edges no longer erases cross marks on other edges (cause: all lines were being subtracted instead of just the newly added ones). Thanks Mitchell Clarke (DireKrow) for the helpful, detailed bug report!
2024-06-12 The line palette was darkened to improve contrast (Martin Ender (Menderbug), Mitchell Clarke (DireKrow))
2024-06-16 Quickly drawing Ls on the standard orthogonal grid is now possible without mis-input. Thanks Dunder_code for the detailed video-report.
2024-07-19 puzzletters PinkHoodie sent 1 classic - thank you!
2024-07-20 Correction after a good unit test by PinkHoodie: edge-less numbers no longer allowed.
2024-07-22 The default new puzzle size is now 6x6, as requested by Rook.
2024-08-03 Local variant edge-given-free, suggested by Rook, can now be used. A puzzle by PinkHoodie was added, as well as two great test cases that yielded a correction. Thanks to Rook and PinkHoodie for feedback and discussion on this variant, which lead to a more precise definition of "intersection".
2024-08-10 puzzletters PinkHoodie sent 2 puzzles using variants edge-given-free and ice,ice-crossing-total,crossing,edge-given-free, the latter a disguised barns puzzle!
2024-08-14 An edge case detected by Rook in the edge-given-free variant was corrected (cause: long free lines needed to be split at grid vertices to register all possible number-clue points). Thank you!
2024-09-05 Overlapping given segments in the edge-given-free variant are now highlighted, to solve an issue detected by Rook. Thank you!
2024-10-11 Crossroads promoted to global variant crossroads. Also, local variant crossrings by Endagorion was added.
2024-10-16 The unequal-lengths variant was adapted to also work on genres with multiple line types like Crossroads (PinkHoodie)
2024-11-22 puzzletters Rever shared a masyu Crossroads variant puzzle - thank you!
2024-11-23 Encoding for Crossroads was corrected. In principle, all puzzles should update automatically.
2025-03-30 puzzletters PinkHoodie prepared 2 Crossroads (classic) puzzles - danke!
