2023-06-16 Thanks to ゆき❄ (Yu-ri) for finding one non-uniqueness in Pedro's puzzle, for making one example puzzle, and for feedback on this implementation! 2023-06-16 Thanks to Lennard Sprong (X_Sheep) for suggesting colour adjustments to distinguish between tiles better. 2023-06-16 Thanks to Karoo for noticing it wasn't clear numbers couldn't be crossed by lines nor shaded. 2023-06-20 Thanks to Sophie (Edderiofer) noticing "turns at crossings" weren't explicitly forbidden yet. 2023-07-12 Thanks to ゆき❄ (Yu-ri) for writing the japanese rules and making the genre page on PuzzleSquareJP2023-07-14 Thanks to Sophie (Edderiofer) for noticing missing auxmarks, now fixed 2023-09-07 Shaded tiles now retain a small border so the colour of the tile underneath remains visible (thus solving a problem found by Kuchiwo Tsugumi (Competor)) 2024-05-04 A recent visual regression causing shaded tiles to default to a lighter colour was corrected. Thanks Sophie (Edderiofer) for noticing. 2024-11-07 Enhancement: the colour of the last loop in RGB ループ Loop is now inferred based on the colour of the remaining two loops. 2024-11-26RGB ループ Loop was updated alongside R・B ループ Loop. Thanks PinkHoodie for sending a test case. 2024-12-06puzzlettersPinkHoodie fashioned 1 RGB ループ Loop puzzle using variant square, (part of the parallel series).
